Why Are My Basement Windows Leaking?

Are your basement windows leaking? Leaky basement windows can be quite an issue, especially if your basement is otherwise finished. Water leaking in can dampen carpet or get on belongings and lead to all kinds of issues. So, Let’s sort out the cause of your basement windows leaking and then find the solution to fix it.

Condensation Vs. Infiltration

The first thing we have to determine about your basement moisture problem is whether it’s caused by condensation or infiltration. You may not realize it, but poorly installed windows, or those that have been installed for many years, can cause enough condensation buildup to appear leaky. This is because old windows lose their insulation over time, allowing the cold, outdoor temperature to draw moisture toward the window from inside.

On the other hand, some windows are working perfectly fine and are just getting overloaded with water. Water pooling against a window is enough to make any window leak. That’s when water infiltration happens, leaving you with a stream of dirty water pooling into your basement. Yuck!

Ground Level

To figure out whether you’re dealing with condensation or infiltration, you should start by knowing where the ground level is. If the ground is above the bottom of your window, there’s a good chance it’s infiltration. However, the easiest way to check is to see if the inside pane of the window is wet. Swipe a hand across the top of the pane. Is it damp? Fogged up? If so, you might just need to lower the moisture levels in your basement, or consider replacing the window to improve insulation.

If the top of your window pane is dry, you’re almost definitely experiencing a leak. Even better signs are visible water pooling at the window or witnessing the leak in action. However, there’s no reason to wait until the next time it rains to take action.

Window Well Waterproofing

If your window is leaking due to water flowing toward it from the ground level, the best solution is window well waterproofing. Fortunately, window well waterproofing is a simple procedure that will stop basement windows leaking and keep your home dry, as intended.

Window well waterproofing is as simple as digging some of the soil out from in front of the window, putting down a drain, attaching your new drain to an outflowing pipe, and then covering the drain in gravel, to keep out debris.

Window Replacement

Some leaky basement windows continue to have moisture problems because they also have condensation issues. If your window is frequently collecting moisture, this is an easy way to develop mold. Old windows that don’t insulate enough to keep away condensation should be replaced when possible.

Dehumidifiers

If you’re not keen on replacing the windows in your basement, you can also invest in a small dehumidifier. This will suck the moisture out of the basement air, making condensation harder to accumulate, even if the insulation of the window is poor.

If you’ve got questions about window well waterproofing or other basement waterproofing procedures, give us a call at POM Waterproofing. We look forward to hearing from you!

How Summer Rain Can Damage Your Foundation

Did you know summer rain can significantly damage your foundation? We want to break down the hows and whys for you so that you can use that knowledge to protect your home from an early retirement. Keep your home in good shape by staying knowledgeable about summer rain and its effect on your foundation.

Erosion

The first way summer rain can hurt the integrity of your foundation is by erosion. This is an issue in any season with rain, but can’t be discounted in summer. When rain water seeps into the ground around your home, it will run toward your house and collect around the perimeter of your foundation. 

However, what many people don’t realize is that ground water doesn’t just sit still. It will continue to flow, taking the slowest route further down into the ground. What this means is that it will continue to flow against the side of your foundation, eroding away the cement or stone supporting your home. Never underestimate erosion. Canyons and valleys are created by a continuous flow of water eroding the ground away, and it can wreak just as much havoc on your foundation.

Crack Widening

While ground water is eroding your foundation, it isn’t just settling for the outside of it. Water also seeps into the cracks in your foundation. You would be shocked if you knew how much water can fit inside of cracks that are barely visible to the naked eye. As water flows through these cracks, they erode away more of the stone, widening the cracks and making them even easier to fill with water. That means, each year, summer rain can exponentially wear away at your foundation.

Expansion and Contraction

Water getting into the cracks of your foundation doesn’t just lead to erosion; it also leads to expansion and contraction. Summer days are often extremely hot – after all, that’s what it’s known for. However, when the rain comes down, it cools everything off. That means, throughout the season, your foundation will go through a series of temperature changes – sometimes sudden – which leads to expansion and contraction of the cement or stone its made of.

The foundation itself isn’t the only thing expanding and contracting; the water in the foundation cracks is too. It’s because of this that erosion is the least of your worries. When water repeatedly expands and contracts within the cracks of a foundation, it creates new cracks, and can even split the foundation. Moreover, when enough cracks form in a foundation, even something as simple as rain expansion within the cracks of the foundation can cause it to split.

When a foundation splits, the different parts are able to move separately from each other. This can lead to one part of the house sinking below another. Even a few millimeters of this can cause structural damage and put stress on the house’s supports. If you notice doors shutting differently at different times of the year, or small hairline cracks in your walls or window frames, your foundation may already be struggling.

Exterior Basement Waterproofing is the only surefire solution to prevent rain damage to your foundation. Call us at POM Waterproofing if you’re interested in learning more about the process or scheduling an appointment today.

How to Prevent Garage Flooding from Rain

Are you struggling to keep rain water from pooling in your garage? This is an unfortunately common struggle with houses positioned at the bottom of a hill or with a down-sloping driveway. However, POM Waterproofing is happy to assure you that there is a very effective solution. Here’s how you can prevent garage flooding when it rains near your home.

Trench and French

The solution to garage flooding is actually very simple. To keep rain water out of your garage, all you need is a combination of a trench drain and a French drain. These are two kinds of drains that, when used together, can stop water in its tracks and reroute it.

The trench drain is installed in front of the garage, spanning the length of the garage entrance. This small, unobtrusive drain has slots in it that allow water to flow into it. From there, the trench drain connects to the French drain, which directs the water elsewhere.

Redirecting Rain Water

What exactly does it mean to redirect rain water? It’s not as hard as it sounds. Instead of letting water just pool inside a drain and stay there, we install a French drain as well. The French drain connects the lower end of the trench drain and runs further away from the house. This French drain gives the same assistance to your yard that a ditch gives to the roads. It simply moves runoff to somewhere less obtrusive. 

If you have a ditch near your house, the French drain may be able to simply connect there and dump the rain water from your driveway into a public drain. If there’s no ditch in sight, that’s no problem at all. The French drain doesn’t need an outlet. It can simply offload excess water into the ground, far enough away from your house that it’s at no risk of running back toward it.

The Process

The process of installing these drains can be slightly involved. If you have a cement driveway, we may need to break away the part closest to the garage entrance to allow space for your new trench drain. Any gaps between the driveway and trench drain upon completion can be patched up easily. 

Dirt or gravel driveways are even easier to install in. We’ll have to dig a small trench across the front of the garage entry, but can cover the area with gravel again when we’re done. In the case of a dirt driveway, the trench drain will remain visible.

The French drain will likely involve digging a small trench through your yard. However, we can dig this along the side of the driveway, avoiding damage to your landscaping. It’s also possible for grass to be pulled back during the trench digging process and then pushed back into place aftward, as the surface layer of dirt is held together by grass roots. That makes the French drain installation process fairly easy to recover from, visually.

Reliable Installation

If you’re looking for reliable French drain installation, trench drain installation, or general help to prevent garage flooding in Toronto, POM Waterproofing is the place to call. We look forward to working with you.

The Danger of Ignoring Basement Moisture

It’s not uncommon for basements to have stone walls. There are unfinished basements with stone walls as well as finished ones. Not everyone opts for drywall when deciding on their finished basement. For some, a coat of paint or raw brick is just more appealing. However, with stone basement walls comes the ability to spot basement moisture. While many people are fine with ignoring basement moisture, POM Waterproofing is here to let you know why this could be a terrible – and costly – mistake.

Where Does It Come From?

The first thing you need to know is, where is your basement moisture coming from? In some cases, basement moisture is just condensation. This comes from your basement walls being uninsulated. Therefore, when they get cold, the moisture in your warm basement collects there. This is the same way your glass of lemonade sweats on a hot day.

However, ignoring this moisture without confirming that it’s condensation can be dangerous. That’s because, on the flip side, you can also get moisture on your basement walls from leaking cracks. If your basement walls have cracks in them, even tiny ones that you can barely see, they can leak in moisture and water from the ground outside.

What Does It Mean?

If your basement walls are leaking moisture in from outside, it doesn’t actually mean a whole lot. Simply put, your basement walls are stone, and stone is fallible against water. Water is able to erode stone at a surprisingly fast rate. Even if your house is only 10 years old, it may be leaking exterior moisture into the basement.

However, while the leaking itself isn’t complicated, the result of it might become complicated. Let’s look at how this can cause long term damage.

Long Term Damage

Basement moisture isn’t something to scoff at. It can go from a slightly damp wall to something worse in no time at all. Here’s how:

The first danger of ignoring moisture problems is the potential for mold growth. Mold loves moisture even more than it loves outright water. When your basement walls are damp all the time, they provide an environment for mold to thrive. This mold can grow directly on the walls, spread to your carpet, get into your subfloor, and ultimately rot the structure of your house. Mold may seem like a mild irritant on the outside, but it can quickly turn deadly.

Not only does moisture risk the rotting of any wooden structural elements, it also poses serious health risks. Even for people who aren’t asthmatic or allergic to mold, breathing in mold spores can cause COPD, pneumonia, and more. This risk is even higher if you have carpeting in your basement, as each step on carpet contaminated with mold will force spores into the air. Mold in carpet is not always visible from the surface, and spores can come through from beneath, leading to an easy-to-miss health risk, all because of wall moisture.

Preventing Basement Moisture

The best way to prevent basement moisture is to confirm the source and take steps to block that source. Condensation is less than ideal, but can be avoided with a dehumidifier. Leaking basement walls, on the other hand, are best managed with exterior basement waterproofing or damp proofing. Give us a call at POM Waterproofing today and we’ll come out to assess your basement as soon as possible.

What Can I Use to Repair Basement Leaking?

If your basement walls have cracks in them, it’s not unusual for them to be leaking water. However, even small amounts, dripping in when it rains, can cause big problems down the line. Mold, bacteria, and pests are just some of the results of leaking basement walls. So, what can you use to repair basement leaking? The answer may not be as simple as you hoped.

Find the Source

The first thing to do is find the source of the leaking. If you’re looking for repair solutions, you probably already know where the water is coming from. If a basement window isn’t doing a great job of keeping out water, you likely need some window well waterproofing. This process is fairly simple. We install something you could call a tray, which catches any water collecting in the window well. The water is then redirected away from the house.

However, if your basement leaking is caused by cracked basement walls, there’s a bit more to be done.

Don’t Fill Cracks

What most people end up looking for when trying to DIY repair basement leaking is something to fill in the cracks in their walls. However, you should never try to fill in basement wall cracks from the inside. 

Because water leaks in from the outside, filling the cracks from the inside ends up trapping water within the walls. The water will then expand and contract with the weather. This will cause a lot more damage to your walls than if you’d left them.

Determine Severity

The next step is figuring out how severe the issue is. During the worst weather of the year, is the leaking simply causing moisture on the inside of the walls, or is it running down and pooling on the floor? If the worst the weather can do is give you some moisture on your interior walls, you likely just need damp proofing. However, if water is coming in enough to pool, even in tiny rivulettes or puddles, you’ll want to go the waterproofing route. 

Both methods involve accessing the basement walls from the outside, which means digging a trench along the side of the house. However, they each offer a different level of protection.

Basement Damp Proofing

When damp proofing, the real culprit is the cracks in the wall, allowing regular ground moisture in. So, when you hire POM Waterproofing to damp proof your basement walls, we fix cracks from the outside and then coat the exterior of your basement walls. The crack repair will build the integrity of the walls back up while the coating will keep moisture from getting in or forming new ones. 

Basement Waterproofing

With basement waterproofing, the culprit is the amount of water trying to get at your basement walls. A high level of ground water will cause damage to otherwise intact walls. This happens when rain collects along the basement wall and erodes the stone.

When we waterproof your basement walls, we do the same process as damp proofing, but take it a step further. Once the wall has been smoothed and coated, we apply a solid membrane and adhere it to the wall. This membrane provides a solid barrier between ground water and your basement. Then, we install a track that collects and redirects ground water that finds its way to the membrane. The water will then be redirected away from the house, ensuring it doesn’t just pool against the membrane.

My Basement Flooded – Now What?

Finding your basement flooded is one of the most stressful situations a homeowner can experience. For most, the immediate response is, “What do I do now?”

Luckily, POM Waterproofing has plenty of experience in the area of basement flooding. Let us walk you, step by step, through what you need to do in the aftermath.

Get Rid of the Water

The first step may seem obvious but, when in a panic, the obvious is often foggy. The first step when you find your basement flooded is getting rid of the water. You can do this one of three ways:

  1. A Bucket
    This method is not easy, nor is it fast or effective. You should only attempt to bail out your basement by hand if you have no other option, financially. It can also be dangerous as flood waters can contain disease and parasites and bailing with a bucket usually leads to contact with the water.
  2. A Wet Vacuum
    A wet vacuum is a vacuum that’s able to suck up liquids. Because this requires the same amount of hauling water outside as bailing with a bucket, it’s also not the most recommended. It does save on time, however, as you can suck up water with the hose, instead of trying to scoop it – which gets difficult the lower the water level gets.
  3. A Pool Pump
    You’ve probably seen one of these before – if not in person, then in a movie. Pool pumps are those long, wide hoses that are used to suck all of the water from a pool when it needs maintenance or is going out of commission. Using one of these can clean up the pooled water in your basement in no time, minimizing long-term damage to your foundation and structure.

Begin Item Recovery

When the basement is clear of pools of water, it’s time to begin salvaging your belongings. Take everything out of the basement. It’s recommended to lay out a tarp on the lawn by the exit nearest your basement. This will allow you to sort through what you recover without spreading flood water and mud all over your house.

Remove Remaining Moisture

When everything is out of the basement, it’s time to get rid of any moisture left. It’s recommended to buy or rent a heavy duty dehumidifier and leave it running in the basement. This will suck up moisture in the air, allowing the space to dry faster.

For any surface you can reach, it’s time to take out your entire closet of towels and begin drying. Save sanitation for later. The goal for now is to get things dry to avoid molding, bacterial growth, and pests.

Ensure Safety

When the basement has been completely dried, let the dehumidifier keep running and begin sanitizing the space. Break out all of your favorite cleaners and use them on every surface that was within a foot of the flood water. This will kill any bacteria that made its way in in the water.

When you’ve cleaned up to the best of your ability, you’ll want to have a professional come out and inspect your basement. Someone experienced in basement flood recovery will be able to spot any areas that may need further help, such as waterlogged wood that may rot. Without an inspection, certain red flags may slip your notice and leave you with hefty remodeling bills down the line.

Avoid Another Flood

If your basement flooded just by severe weather, it’s time to prepare for future flooding. If it can happen once, it can happen again. Therefore, if there was a specific source for the flood water, such as a window well, window well waterproofing could save you from another disaster. However, if cracks in your foundation or basement walls are the culprit, it’s time to invest in basement waterproofing. Keep your house lasting as long as you do by investing in your future.

How to Repair a Damaged Foundation

A damaged foundation is bad news for anyone. Your home’s foundation is what keeps it “alive.” Without it, the rest of the structure would quickly fall victim to shifting ground and instability, making the building dangerous to live in. So, how do you know if your foundation is suffering? What happens if it is? Can you repair a damaged foundation? POM Waterproofing has answers to all of your questions and more. Let’s take a look!

Is My Foundation Damaged?

The first step to anything foundation related is knowing if it’s damaged to begin with. There are obvious warning signs from both inside and outside of a building.

Signs from the interior include:

  • Cracks in your sheetrock/drywall
    (Not your paint. Old paint get’s little cracks in it over time and this is harmless.)
  • Cracks in your flooring
    This is most noticeable with tiling or the cement floor of an attached garage.
  • Doors or windows that aren’t aligned correctly anymore
    Have you ever noticed your doors suddenly closing more or less easily during certain seasons? This is due to shifting in your foundation.
  • Floors being uneven
    Your foundation was built to provide a flat, even surface for your house. If the floors of your house are not completely flat, the foundation has shifted.

Signs from the exterior include:

  • Cracks in exposed parts of your foundation
  • Gaps between exterior doors or windows and the exterior wall
  • Displaced moldings, doorframes, and window frames
    If there is a gap between the frame or molding around a door or window and the wall that it should be sitting against, something is amiss. 
  • Cracks in exterior brick or stone walls
    Cracks in the mortar between bricks is bad enough, but any shift in the foundation that can apply enough pressure to crack the bricks themselves is noteworthy.

How to Prevent Damage

If you’re not seeing many of these signs, your foundation is probably fine. However, if you see one or two things that seem like they might indicate the beginning of a problem, there’s a way to prevent that problem from getting worse.

To prevent a damaged foundation, you should heavily consider damp proofing or waterproofing for your exterior. This process is somewhat involved. It aims to install a barrier between your foundation and the surrounding ground. This is very effective at stopping damage from groundwater and moisture. It can also be used to prevent moisture from leaking into basements, which is a leading cause of basement mold.

Can A Damaged Foundation Be Repaired?

The amount of damage a foundation can accrue before it is irreparable is quite extensive. Repairing a foundation actually comes with many solutions. This is especially true if you catch the damage early on. Foundations that are beginning to shift position due to the shifting ground beneath it are some of the easiest to repair – though the process isn’t simple nor cheap.

How to Repair a Damaged Foundation

If you need help repairing a damaged foundation, you’ll need to contact a local specialist. The repair will typically involve digging into the surrounding soil to expose the foundation. Your specialist can then repair it from beneath by applying supports. This uses a method called slabjacking.

If you have questions about damage prevention, waterproofing, or damp proofing, you can get all the help you need right here. Call us at POM Waterproofing and we can help you avoid any future need for foundation repair.

How Damp Proofing Can Protect Your House Structure

The #1 thing that destroys houses is simply time. Or, specifically, it’s the environment with the addition of time. This is the exact reason why abandoned buildings fall apart. With no one around to mitigate the damage done by the environment, they simply fall apart. Do you want to protect your house structure from the environment and minimize the amount of upkeep it needs to remain its best? Damp proofing is exactly what you need. Now let’s jump into why!

Ground Moisture Destroys Foundations

You might expect rain and wind to be the biggest environmental opponents your house has to withstand. However, the real opponent is much more insidious. Wind and rain can do a great deal of damage to parts of your house that are cosmetic or easily replaced. However, ground moisture has a much bigger impact on your house structure. The parts of your house that are hurt by ground moisture are difficult, or even impossible, to fix once damaged.

Let’s look at your foundation, for example. The foundation of your house is possibly the most important part of it, structurally. Without the foundation, your house would only last a few years before succumbing to moisture damage, ground shifting, and more. After a few years, any foundation will begin to get microscopic cracks in it. These are no big deal with they’re small. They show up from the earth around the foundation shifting slightly with each passing year. The changes are so small that their effect is really very small.

However, when these tiny cracks appear in your foundation, it creates a place for moisture to hide. The moisture in the ground around your foundation will seep into those cracks and make them worse. There are 2 ways they do this:

  1. The moisture flowing from crack to crack erodes the foundation the same way a river can create The Grand Canyon.
  2. Changes in temperature lead to that moisture expanding and contracting, which forces the cracks to widen and spread.

Structural Integrity

As you can imagine, the faster your foundation deteriorates, the faster other parts of your house structure do. For example, a damaged foundation makes it harder to protect your house structure from mold.

Houses with basements will experience the same struggle with basement walls as they do with their foundation. The difference is, the cracks in your basement walls will easily reach all the way through. This can lead to basement moisture problems and mold.

Mold is a particularly dangerous thing to allow a foothold. Once mold growth begins in your home, it’s very hard to get rid of. This is especially true when mold manages to make its way into your house structure, such as the wooden framework. It’s nearly impossible to protect your house structure and framework from mold once it’s taken hold. The best way to protect your house structure is to prevent damage to your foundation and basement walls before it happens.

A Long Lasting Home

If you want to keep your foundation and basement walls from falling victim to moisture damage, it’s time to look at how damp proofing can protect your house structure. Damp proofing creates a barrier between your foundation and the ground, keeping water and moisture from reaching it in the first place. POM Waterproofing does damp proofing for the entire Toronto area, and we can do it for you too. Give us a call if you want your home’s structure to remain its best.

Why Is My Toilet Backing Up?

Is your toilet backing up? We’re truly sorry to hear it! A toilet backing up is one of the most unpleasant experiences one can deal with. The question you’re asking now is, why? What is the cause? After all, the first step to fixing a problem is knowing what’s causing it. POM Plumbing is here to help. Let’s start at the beginning.

What Is Backing Up?

If you’re not sure what a backed up toilet is, it’s when there is sewage coming up from your toilet or other drains in the house. That can mean you have sewage coming up from the tub drain, or even sinks as well. If you need help with a clogged toilet, that’s a different beast, and usually much easier to fix. Not sure how to tell the difference? A clogged toilet will only have recent waste in it. A backed up toilet can have old waste as well and will usually look muddy, as it contains waste that has already broken down.

Flooding the Pipes

The reason you’re dealing with a back up is actually because of something called backwater. The root cause of this is that there is a clog somewhere further down in the plumbing system. Because that clog is keeping things from moving along, every time someone flushes a toilet or takes a shower, the waste level rises. The additional water and waste ends up flooding the pipes. That’s where backwater comes in. The waste begins to move backwards, filling all of the pipes in the home’s plumbing system until it overflows into a tub, sink, or toilet – or out of them.

That clog causing the backwater can be as near as the intersection between the tub and toilet drain pipes. It could be where your home system dumps into the local system. It can even be as far as where the local system dumps into the city system. As long as there is a clog somewhere in the plumbing system, enough water added to it will begin to cause backwater.

Home or Local

So, the question is, how do you know if the problem is home or local? Without doing an extensive inspection of your home system, there are two easy ways to find out. The easiest is to call your local plumber. If the problem lies beyond your home, they’ve probably already received hundreds of calls from the other locals. If they haven’t, you can also check with your neighbors. If they’re having issues too, call back your local plumber and let them know there is likely a local blockage. This will allow them to get to work right away and minimize damage. Plus, early response can prevent disaster in all of your neighbor’s houses, as they can be notified.

Solving the Problem

The solution to backwater is actually quite simple. You need a backwater valve. Backwater valves are legally mandatory in many parts of Canada and are often necessary for insurance to cover backwater flood damages. However, even though many homes are built with them, there are many that are without. It could be from poor construction or because the house is old and never had one to begin with. If you don’t know that when buying, it’s best to have one installed right away.

A backwater valve prevents sewage from the local system from being able to enter your home system. It makes it a one-way exit for your own sewage and keeps all of your neighbors’ waste from reaching your toilet.

If the problem is just within your house, a backwater valve won’t help. However, POM Plumbing can. Clogs within your own plumbing can be equally disastrous if not handled quickly. So, give us a call and let us come out and rid your pipes of clogs.

What Is a Backwater Valve?

If you’re looking for the solution to your problem and keep seeing talk of backwater valves, you may be wondering what, exactly, they are. A backwater valve is what’s used to prevent sewage from the local sewage system from entering your home system. How does that work and why is it necessary? Let’s dig into the details.

How Does a Backwater Valve Work?

The first thing you may be wondering is how exactly a backwater valve works. It’s actually fairly simple. In laymen’s terms, it turns your sewage main into a one-way exit. The cover of the valve will only open one direction. That means any sewage that presses against it from the other side will only push it more firmly shut.

Why Is a Backwater Valve Necessary?

A backwater valve is a huge necessity when it comes to safety, hygiene, and keeping your home undamaged. Because backwater is full of other people’s waste, having it back up into your home is a huge hazard, especially if it overflows. Not only is it gross, a backup will introduce tons of foreign bacteria into your home. You also can’t rule out the presence of parasites and disease – both common presences in sewage systems. A backwater valve keeps all of this gross matter from gaining access to your home. We think that’s pretty important.

What Happens During a Local Backup?

Remember how we said that when your local sewage backs up, it closes the valve? Because of this, if your local area has a sewage backup, your own home may have its own. That’s because, while local sewage isn’t able to get in, your sewage also can’t get out. Fortunately, it would take you a while to fill your own pipes all the way up with sewage. Therefore, you only need to do a little bit of damage control, mostly regarding water usage.

As soon as you catch wind that there’s a local sewage clog, you’ll want to minimize water usage. This helps to ensure you don’t flood your own house while you’re waiting for the local sewage problem to be solved. As you can’t be positive how long it will take them to solve the problem, it’s best to be cautious.

  • Don’t take any showers or baths
  • Don’t run washing machines or dishwashers
  • If you don’t have a dishwasher, save washing by hand for later too, as it often uses up even more water than dishwashers
  • Keep sink use to the bare minimum by washing hands quickly and turning off the water while you lather with soap
  • Refrain from flushing the toilet unless you’ve pooped or there’s a few uses worth of toilet paper waiting to be flushed (we don’t need to add more clogs to the mix)

How Do I Install a Backwater Valve?

Backwater valve installation is quite intensive and can only really be done by a professional. It involved digging a trench and messing with some of the biggest pipes in your sewage system. Therefore, you don’t want to DIY this. Plus, it’s quite a dirty job. Fortunately, you can count on POM Waterproofing to serve you anywhere in Toronto. Give us a call if you’re interested in backwater valve installation and we’ll make it happen!
