Andri and his team did a fantastic job waterproofing two area’s around the external foundation of our home. From the consultation with Andri through to execution was seamless and very informative. Andri is really knowledgeable and great to work with. The team was on time, neat and fixed the leaking coming into our basement. I will definitely contact them again in the future should we have any further issues.

Carl came by for a second quote on a drain line replacement, and took the time to make sure we needed the work done. After 30 minutes of work we talked through what was actually needed and ended up saving us thousands. So generous with his time, excellent communication, trustworthy & above all just a super decent person. Highly recommend.

Andrew and his team are true professionals. They installed the backwater valve at my tenanted property in Etobicoke recently. I was having a toilet water clogging issue. I contacted my previous provider first but they did not help out with this issue. When I connected with Andrew, he came the next day and inspected the property and discussed the issue. I even did not meet him, he gave me a quote and it was quite reasonable. Andrew discussed with me the whole process. Within a week they installed the backwater valve. They came on time and finished it. These guys are amazing. I will not hesitate to contact them for any similar kind of issue or for other services if I need.

Andrii came to look at our basement leak and was extremely helpful. He made some suggestions to help us isolate the problem and came by a second time to follow up. He assessed that the solution was something outside of scope of work for his company, but helped us get connected with a contractor who could do the job. I really appreciate his honesty, expertise, and friendliness, and would recommend Canada Waterproofers to anyone with a wet basement problem!

We’ve used Canada Waterproofers twice and had excellent service both times. A few years ago, they waterproofed our basement wall along the driveway, and they repaired the concrete driveway after the ground had settled. Recently, when we found water on the floor, we called Carl to help with a leak that appeared to be in our main stack. Carl sent Peter who expertly diagnosed and fixed the problem with minimal damage to the drywall. He replaced the kitchen drain pipe connected to the stack and replaced a faulty shut off valve under the sink. All of our interactions with Canada Waterproofers have been friendly and helpful. We have recommended them to family and friends.

I had a fantastic experience with Canada Waterproofers! Salesman Andrew was exceptionally knowledgeable, friendly and guided me through the entire waterproofing process as well as all possible options to solve my problem. He answered all my questions over multiple phone conversations and visits and never made me feel as though I was a bother. The hardworking crew, Dmitri, Victor, and Grigorii, displayed remarkable attention to detail and completed the job flawlessly all while keeping a tight, clean work area so my family could continue our daily routine without interruption of any kind. Haven’t seen guys hustle like that in a long time. I don’t often hire contractors to do work and when I do I take my time to find the right contractor. I can be picky and tough to please as my attention to detail can be excessive These guys hit the mark! Don’t look any further when hiring someone to perform any task listed on their website. My basement is now dry and secure. I highly recommend Canada Waterproofers for their expertise and dedication.

Slava Koval was the best!!! We had 2 different companies who came and quoted us tripled what we paid him. He was very honest and thorough. The other 2 companies couldn't provide us a straight answer and provided us insane quotes. I googled and found this company and gave it a shot. He came by right away to do a camera inspection and was blown away by his expertise. He told us what was wrong right away and helped us with other things. He even offered us complimentary camera inspection after 6 mos. If you google his name you'll see all happy clients. You wont be disappointed. Very honest guy and doesnt rob people! Thanks Slava and Canada Waterproofers!

I called this company to come investigate my basement leak and fix immediately. Upon investigation, it was made know it's was a plumbing issue. I dealt with Andrew and I couldn't question how intelligent he was which speaks from his years of experience. He did not have to rip the wall open. He walked around the house and checked all the wall outside etc .Oh well, it was indeed a plumbing issue and we paid nothing to get the leak source investigated.Thanks so much Andrew for your intellegent.I will recommend this company because it's clear they have experience employees that are ready to help and not take advantage.

Carl and his team did an excellent job waterproofing a large section of my foundation, when finished everything was neat and clean. Carl and his team took pictures and videos during the repair which was very informative and helpful. Throughout the process he has been very responsive and accommodating, always happy to answer any questions that we have. His prices are reasonable and I would highly recommend him and Canada Waterproofers to anyone in need of waterproofing.

Valentine from Canada Waterproofers came to my house and did a FANTASTIC job repairing a water leak we had. He diagnosed where the leak was coming from and then voluntarily chose to repair it with a high quality copper pipe which typically would've costed more. He also noticed another issue with the pipes where the previous contractor had implemented a poor shortcut solution that would've broken down over time and fixed that proactively as well. Valentine and Canada Waterpoofers went completely above and beyond my expectations and did even more than what was required of the job. They did all this at great value for the dollar as well. Highly recommend this company and technician. Thank you for your service!!!

We had a problem with our shower drain leaking and a botched repair job by a previous plumber. We needed to call in the real professionals this time and Val was our guy. Rest easy if he's the one to answer your call.From his calm and calculated demeanor to his willingness to listen and provide the right solution, it was an absolute pleasure to deal with someone at the top of his field. Highest recommendation!

Boris is a true professional 5 star rating plumber because he determined the source of the 2nd floor shower leak right away which 3 others plumbers from other companies failed. He fixed the problem without opening the main floor ceiling. He showed up on time, ensured quality service and charged us a reasonable price for fixing the shower, replacing garburator and replacing kitchen faucet. All 3 issues completed in less than 2 hrs. We are so glad we found Canada Waterproofers online. We will strongly recommend Boris from Canada Waterproofers to our families and friends for their plumbing problems.

This is the second time I have used this company's services. My kitchen drain was severely clogged, and my attempts to use a plumbing snake were unsuccessful. Later, I called Karl, and their service was very prompt—they came the same day and fixed the issue within an hour. They were very professional. The technician was not only efficient but also very friendly, explaining the root cause of the problem and preventive measures in detail. Over the years, I have never considered switching to another company. Their service has always left me extremely satisfied.

Carl and his team consistently provided outstanding customer service with quick responses, willingness to answer questions and explain issues clearly, giving us high degrees of confidence in their work. They made these stressful situations more manageable than we expected or imagined. We highly recommend their services. One of the best experiences we ever had with a house-related specialist.

I am always skeptical of companies in these types of industries receiving so many 5-star reviews but with this one, I get it. Similar to others, we had a fantastic experience with Canada Waterproofers. They did interior waterproofing (with sump pump installation), camera inspection and service pipe replacement (from outside the house), as well as a main water valve change for us. Andrew/Andrii (the client rep) was a joy to deal with; responsive, friendly, detail-oriented, and gave the most competitive quotes (balancing experience and price) out of the many places I reached out to. Andrew the technician and the rest of his team were also great; they were on time, worked efficiently but carefully, and were communicative and professional throughout. We had a complicated service pipe issue that required detailed inspection and some analysis on how best to tackle it and Carl (the owner, I believe) came to do the inspection himself, who was extremely knowledgeable and clearly very experienced. We received detailed quotes before accepting the jobs as well as professional looking packages with warranty certificates, etc. following completion. The way this company presented itself - which it then backed up with its work - made us feel confident and comfortable throughout the process and brought my anxiety way down (which is not an easy thing to do, as I'm sure Andrii, who patiently answered my many, many calls and questions, can attest to). I have yet to find any reason not to go back to them for all plumbing/waterproofing related work in the future.

Andrew and his team did an amazing waterproofing job for our basement. Andrew came to our house to do the estimate and I received the quote the next day with all the details.

I definitely recommend Canada Waterproofers for anyone who needs that kind of project to be done.

I've worked with Slava and his team multiple times. Once for basement waterproofing, the second time to fix a sewage pump disaster that another tradesman caused, a 3rd time to upgrade the water supply, and a 4th time to fix an emergency plumbing issue. All on different properties and occasions, and all of which have been excellent work done! Slava and his team are experts at what they do, pricing is fair, and always professional. There's a reason why I keep going back. Don't look anywhere else, this is the team you want to work with when it comes to waterproofing and plumbing!

Carl and his team waterproofed our exterior back wall a few years ago. They were professional and gave me a great price.I recently had some drain problems inside my house and as Carl and his team are also plumbers I felt comfortable asking their opinion. Carl came by and his drain camera showed us what the problem was. The previous drain installation was done incorrectly. So Carl sent his team a few days later to dig up the problem which was a p trap placed in the wrong spot. A new straight pipe fixed the problem!We no longer have issues with blockage and our wallets didn’t suffer the extreme damage that another person quoted.Bottom line, the best prices for the best work anywhere in Toronto for sure!Thank you Carl!

     Backwater valve costs

The issue of our times is a changing climate, and the impact that has on all of our lives. As the air becomes warmer, and temperatures rise up, that means a more intense water cycle, with more moisture evaporating into the atmosphere.

That leads to changes in rainfall patterns, and more storms. Downpours are more intense. There is more snow, which melts more rapidly.

With an increase in precipitation comes an increased risk of flooding. If you own or rent a house, with a basement, you know what we are talking about.

The home’s foundation drainage system is interconnected and complicated, and includes the city’s sanitary sewer lateral, perhaps a storm service lateral (in newer homes), a weeping tile system that channels water away from the foundation, drain pipes and sump pumps. Any failure there leaves the home exposed to flooding.

BASEMENT FLOODED HOME REPAIR COSTS THAT CAN TOTAL THOUSANDS

For most people, purchasing a home will be the most significant investment they make in their lives.

How many of us though have directly experienced, or heard horror stories, about walking down the basement stairs to find a foot or two of water, or a cascade of water pouring into a finished basement through a clogged-up window well during a heavy rain storm, personal possessions being washed away forever in some cases.

Cost estimates to fix water damage vary – but it’s in the thousands, all to repair or replace drywall, floors and hardwood, or anything electrical. Those home repair costs go up the more the water damage is left untreated, or if the homeowner is dealing with clean water as opposed to a sewer backup, or contaminated water. Around $1.7 billion is paid out in insurance claims due to water damage in Canada each year.

Moisture will spare no part of the home – timber, block structures, floors, and bricks. Many people spend a lot of money finishing a basement, perhaps creating a rental apartment for income purposes, all to help push up the value of that investment, only to have to do the work again.

For homeowners the issue becomes balancing the potential repair costs associated with a flood with buying flood insurance from your provider. That becomes even more of an issue for people living next to waterways – in case a river or body of water overflows.

Then there are the health effects – water damage leads to mould and mildew growth. You look at it and it seems harmless, but mould spores can travel anywhere, and can lead to throat and eye irritation, coughing, headaches, fatigue, fever, skin problems, nasal congestion, nose bleeds and allergies. It is important to not only get rid of it when you see it, but stop it from showing up in the first place.

HYDROSTATIC PRESSURE AND WATER LEAKS

So why does water leak into your basement?

Maybe you have heard the term “hydrostatic pressure”. By definition, it’s the pressure exerted on a fluid at equilibrium (not flowing) by the force of gravity. Hydrostatic pressure increases the deeper you get from the surface due to the increasing weight of the fluid from above.

Hydrostatic pressure is the reason you see water leaks in the basement of a home. Water that is building up against the foundation wall will eventually leak through eroding concrete, at the joint where the poured concrete floor meets the wall, and through cracks in the wall, mortar joints or floor if left un-checked.

With more precipitation, that becomes more of a factor, especially as the soil becomes more saturated. The more loose the soil, the more water it absorbs. That expanding soil also puts more pressure on the foundation walls. In the event of heavy rain or a rapid snowmelt, water tables will rise, putting pressure on a basement.

DO-IT-YOURSELF FIXES

You can’t control the weather, but you can control how well you protect your home. If you want to stop water from leaking into your basement there are a number things you can do on your own.

• Landscaping should be a focus. You need to keep the water away from the house. Slope the ground away from the foundation, around six to 10 feet. Install asphalt or patio stones next the home, so water doesn’t settle into the soil.
• Make sure the eavestroughs and gutters around the home are clean. Water will overflow if they are clogged by dirt or leaves and will over-saturate the ground next to the foundation walls
• Make sure downspouts are directed to where you want the water to go, like a garden
• A window well with a clogged drain can lead to water flooding into the basement. Placing covers over each of the window wells will help keep out leaves and other debris that can lead to clogs
• Clear snow away from the home’s foundation during winter
• Protect your HVAC system – make sure the furnace and water heater is not sitting on the basement floor

But if you really want to stop the problem of flooding at its source, you need an exterior (hyperlink) or interior (hyperlink) home waterproofing system.

A healthy debate is always good, especially if there is some positive that comes out of it – personal illumination on an important topic, that directly and positively impacts something in your life.

When the topic is home basement flooding, and what route to take to best protect your home investment in the event of a water leak, or flood, there are many factors at play when considering what to do about it. And is there anything more important than protecting your home?

Most important, right off the hop – don’t rely on your average Google search for answers to queries. Google is a good place to go for cursory understanding of basement waterproofing, but always call on licensed pros to come to your home and give you an honest assessment. Canada Waterproofers will come to your home for no charge.

DON’T MESS AROUND WITH BASEMENT WATERPROOFING

Your home is far too important, far too sizable an investment – from the financial perspective, especially if you are balancing a hefty mortgage, plus the perspective of minimizing any emotional impacts that come with your basement being swept away in a flood.

Water pooling, stains on the walls and floor, musty odour, rotting and rusting – it’s bad news all around. Even with small water leaks into the basement, the longer term, more insidious, impacts include those on your health, and the health of your family – mould and mildew can lead to breathing problems, eye irritation, skin rashes, headaches, fatigue, fever, and coughing.

A pro from Canada Waterproofers will do a full analysis of the inside of your basement, the outside foundation area of your home, the state of the window wells and eavestroughs, even how the earth is graded up against the home’s foundation, and whether there is anything else close to the home that is storing excess water, that might be contributing to increased water pressure up against the basement walls (called “hydrostatic pressure), which in turn lead to basement leaks.

They will even take a look at how close your home is to any neighbouring homes, because that will impact their basement waterproofing recommendation. There are many factors that go into a professional assessment.

TOP 5 REASONS TO GO WITH EXTERIOR WATERPROOFING

• Absolutely the best, most complete way of protecting your home from a basement leak or flooding, involving the excavation around the exterior perimeter of your home, down to the base of the home’s foundation, cleaning the walls and replacing cracks, applying aqua bloc foundation, installing fiber mesh around the perimeter for reinforcement, installing drainage membrane on the walls, installing a new weeping tile or drainage system below the basement floor. Gets to the root of the problem.
• Exterior waterproofing prevents water from seeping deeper into your home, causing untold damage to walls and floors. Helps keep the structure of the home strong.
• It’s more expensive (starts at around $100 per foot and can go to $1,000 per foot, depending on the size and difficulty of the job), because there is more work and material involved, but it stops water from leaking through the foundation of your home, which can cause the foundation to weaken, and that saves you more money in terms of repair costs in the long run. Put a dollar figure on peace-of-mind.
• Exterior waterproofing techniques are constantly evolving and improving, translating into a more protected, safer home.
• Relatively fast and efficient process – could be one day, or one to two weeks, depending on the job.

TOP 5 REASONS TO GO WITH INTERIOR WATERPROOFING

• It’s more inexpensive than the exterior option (anywhere from $75 per foot to $250 per foot).
• Close proximity to neighbouring homes, restricted space, the presence of an outside deck, or the looseness of the soil around the exterior of the home, all might make the excavation work associated with exterior waterproofing impossible. The process of installing an interior waterproofing system doesn’t involve the high level of disruption like with exterior waterproofing.
• Insulating the basement wall, part of the process of interior waterproofing, will prevent condensation from forming behind the wall, as long as spray foam insulation is added on top of the membrane when the waterproofing is complete.
• Interior waterproofing pumps out water that has already entered your basement, as opposed to exterior waterproofing, which keeps it out – but it’s still a very effective method of keeping your basement dry and safe.
• It’s a comprehensive waterproofing system with several back-ups built in – including a battery back-up for the sump pump, which collects water from the pipe/drain system installed around the home and pumps it out to a safe location away from the basement, which gives the homeowner peace-of-mind knowing the basement is being kept dry in the event of a power outage.

Some Canada Waterproofers’ clients have opted for both options, for even extra coverage. Contact a licensed pro today, for an assessment.

Exterior waterproofing is the most effective method of protecting your home from basement leaks. It’s also the one method of home waterproofing that involves the most work, especially during the soil excavation phase.

It’s certainly not a DIY project to be completed over a weekend. There are multiple steps involved. That’s why it’s important to have licensed professionals take on the job.

Everyone wants a dry basement. With more rainfall comes more water pressure on the foundations of the home. A small water leak plugged up by a sealant fix off a YouTube video can soon expand into a full home flood.

THE COSTS OF EXTERIOR WATERPROOFING

Cost estimates to fix water damage vary – but it’s in the thousands, all to repair or replace drywall, floors and hardwood, or anything electrical. Moisture will spare no part of the home – timber, block structures, floors, and bricks. Those home repair costs go up the more the water damage is left untreated, or if the homeowner is dealing with clean water as opposed to a sewer backup, or contaminated water. Around $1.7 billion is paid out in insurance claims due to water damage in Canada each year, according to the Insurance Bureau of Canada.

The basement is often used as a living space for the family, a work area, or an income-generating rental apartment. The potential consequences in leaving the basement unprotected from water leaks are too dire. It’s vital to deal with any potential problems at the source.

THE STEPS INVOLVED IN EXTERIOR WATERPROOFING YOUR BASEMENT

Canada Waterproofers provides solutions to all challenges, including a close proximity of neighbouring homes, and the impact a major excavation like this can have on the aesthetics of property, like trees and gardens.

What are the steps involved in exterior waterproofing?

• Protect work areas with tarps.
• Excavate down to the footing level or base of the home’s foundation, around the full perimeter of the home (which holds up the walls of the home), and expose the footing and wall ready for the waterproofing application. Often there is a bulldozer and other machinery involved in this.
• Clean the wall, repair cracks by grinding them out into a “v” and repair with hydraulic cement, applying a parging mix (meant to coat a water-resistant barrier). Hydraulic cement will expand as it is curing to cover up the cracks.
• Apply foundation aqua bloc, which provides a rubberized asphalt membrane on the top of the repaired cracks in the cement foundation.
• Apply fiber mesh (yellow jacket) for reinforcement and then another coat of aqua block and polyurethane (four-millimetres thick) for additional protection.
• Install Delta MS drainage membrane (made of long-lasting polyurethane and recyclable materials, another added feature which keeps your basement dryer) with delta clips, finishing the moulding along the top with tapcon screwsT
• Remove the old weeping tile and install a new “Big O” weeper with filter and connect to the existing weeping tile pipe, below the basement floor.
• Encase weeper (which sits on the soil) with ¾” clear gravel (one foot of gravel above the weeper), and then install the filter on top to separate gravel from soils. Without the gravel on top of the new perforated weeping tile/pipe, and the soil below it, the system won’t work, since dirt will clog the holes in the pipe.
• Backfill and compact the ground every two feet until backfilled.
• Install gravel finish, clean work areas and remove access debris from the site, re-planting the garden around the home if necessary.
• Important point – before any excavation is started, the hydro and gas companies, as well as Bell or Rogers, will need to be contacted, to ensure workers are not cutting or digging into pipes or lines.
• Install new window wells with drainage pipe if required.
• You also might want to install a sump pump (there should be a three-year manufacturer’s warranty on all mechanical pumps).

Exterior waterproofing is a comprehensive, labour-intensive process. The process can take a day, or one or two weeks, depending on the job. Get it wrong, and not only will water still be leaking into the basement, but you’ll have to dig everything up and go at it again. Nobody wants the extra money and the headaches that will come with that scenario.

It might not seem like it now, with the snow and sub-zero temperatures, but spring will be here before you know it.

Spring is party time for your garden, and the flowers and trees around your property – but another thing entirely for the basement of your home.

Maybe you notice a feeling of dampness or brownish stains on the walls and ceiling, mildew, stains on the carpet, or rust stains on the floor that comes from water corrosion to metal like nails, and electrical boxes. Basement flooding is a messy and expensive reality. But you are not alone. Many homeowners face the same challenges.

Usually a big part of addressing any problem is figuring out why something happens in the first place. In the case of basement flooding we know the answer – water pressure that builds up against the home’s foundation. The more rain there is the more pressure is created by water in the loose soil around the basement. That pressure pushes water through the walls and floors.

But that’s not the only reason – during heavy rain, city sewers can become overloaded, and can back up water and sewage into homes. Municipal infrastructure is aging.

Older Homes Are More At Risk Of A Basement Leak

This has become such an important issue the City of Toronto introduced a subsidy program so homeowners can have a basement waterproofing system installed.

The city offers owners of single-family, duplex, and triplex residential homes up to $3,400 per property to install flood protection devices like a backwater valve (a backwater valve is a device that prevents outbound water from the home to re-enter through the home’s drain pipes), a sump pump and the capping of a home’s storm sewer or external weeping tile connection. Have a look at the rules here and keep in mind you’ll need licensed, professional waterproofers to do the job.

Clogged eavestroughs or downspouts, and clogged window wells or poorly sealed stairwell doors, also cause flooding and basement leaks.

Older homes – where mortar joints around cement blocks have worn down, older pipes are no longer sealed properly, cracks emerge over time in the walls and floors, or the joints where the concrete floor meets the basement walls start to break down – are the highest risk.

With climate change comes an increase in precipitation.

So how do you fix the problem? All homes, old and new, need to have a basement waterproofing system in place. Contact a basement waterproofing company to install either an exterior or interior waterproofing system – or both.

Interior basement waterproofing features a drainage system led by a sump pump that is connected to your home’s drainage tiles, pumping water to a location outside of the home, minimizing those water pressure effects. Those drain tiles will collect water that’s flowing throw cracks in the cement of the wall or via the area where the floor meets the wall.

Exterior Waterproofing Is A Very Effective Way Of Preventing A Basement Leak

Exterior waterproofing is a more comprehensive, multi-step job, involving major excavation work, installing protective coating and a drainage membrane, as well as a new weeping tile system, but it’s a highly effective way of keeping your basement dry.

Exterior waterproofing is most definitely not a job that should be left to amateurs or weekend warriors.

Overall, a basement waterproofing system will funnel water away from your basement.

The damage caused by a basement leak, leading to water damage to dry wall, wiring, floors, mould and mildew issues, can run the homeowner into the thousands of dollars. There is also the incalculable emotional cost that comes with seeing family possessions and heirlooms permanently destroyed.

Taking care of the home while keeping it dry is key in maintaining or increasing its value. A home purchase is the most important investment most of us will make in our lifetime. And property values around the GTA are only going up. Many homeowners have converted their basements into rental income opportunities, making a home waterproofing system that much more economical, from an investment perspective. Better to get ahead of any potential basement leak issue now.
