Exterior Basement Waterproofing Toronto

Everybody wants a dry, safe, healthy home. But our changing climate isn’t a situation that is going to reverse itself suddenly. The home’s foundation walls and basement floor are under constant water pressure (hydrostatic pressure, as the soil becomes more saturated). This situation worsens with heavier rains and more rapid snowmelts, on top of the fact that city sewer and drainage infrastructures are ageing and are less reliable.

So perhaps you find water in the basement or water stains on the walls. Probably there is a musty smell, or the onset of mould, in the basement area.

Inaction is not a solution – it will only get worse. Water will always find its way through – concrete is a porous material. It will absorb water. It will erode over time. A particularly vulnerable area is where the concrete floor meets the wall, or through the mortar between concrete blocks.

Of course, you can do it yourself. YouTube has plenty of DIY waterproofing videos, and you can apply a sealant to cracks, but that’s more like a finger-in-a-dam solution.

The most proactive, effective way of tackling the problem is an Exterior Waterproofing solution.

It’s a major excavation project. There is a lot of soil to be placed up on the ground. It requires expertise both in the products being installed and the process of installation itself. For example, without the gravel on top of the new perforated weeping tile/pipe, and soil below it, the system won’t work. The holes in the pipe need to be pointed the right way (down). A fabric barrier and gravel in the system helps keep dirt from clogging holes in the pipe. There are many different steps involved.

If done properly, this is the best way to protect the basement of a home from water seepage, or worse, a flood. It tackles the problem at its source.

But it’s complicated and labour-intensive, and needs to be done the right away. Get it wrong and water will still leak in. It will be challenging to go back for a do-over. It’s probably best to leave a job like this in the hands of professionals – so it’s done correctly the first time.

We had serious water issues in our basement, and after searching for a reliable waterproofing specialist, we finally found Canada Waterproofers in mississauga. They inspected the whole house carefully and suggested the right waterproofing solution instead of pushing unnecessary work. The results are amazing, no more leaks, no damp smell, and the walls look completely dry. I am really happy with their professionalism and honesty. Highly recommend them for anyone needing house waterproofing done right!

Had wet basement issues since long time, friend recommended us Canada Waterproofers, I think it was the best decision to get in touch with them. Carl and crew came and did foundation repair for us along with battery backup sump pump installation, all at a very affordable price. 5 stars to them!

Water used to come in through small cracks inside our basement walls, and the smell was getting worse every week. We decided to go for interior basement waterproofing, and Canada Waterproofers handled everything perfectly. They worked carefully, kept the area clean, and now the basement is completely dry and fresh. Couldn’t be happier with the results!

Our old sewer line kept backing up and digging up the yard was not an option. Carl suggested trenchless sewer replacement and it worked perfectly. Canada Waterproofers finished the job fast with no mess and the flow is smooth now. Super professional and easy to talk to. You can really tell they care about doing the job right. I felt completely stress free from start to finish and highly recommend them to anyone with sewer problems. Great work!

We had a major sewer line issue that caused slow drains and a terrible smell around the house. We called Canada Waterproofers and their response was quick and professional. They inspected the line with a camera and explained our options clearly. The crew handled the full sewer replacement efficiently, minimizing disruption and cleaning up perfectly before leaving. Everything is flowing smoothly now, no more backups or bad smells. Excellent service and honest communication from start to finish!

I had a foundation leak, and the job was done by Canada Waterproofers. I was fortunate to connect with Andrii, the project manager. He is very knowledgeable, prompt, and easy to communicate with—he even answered my calls after working hours.I had my entire house waterproofed. Andrii explained everything in detail, and the price was very reasonable. His crew, especially the foreman Andrew and his team, did an amazing job. The work was extremely clean and professional, and I am 100% satisfied with both their knowledge and workmanship.I highly recommend Canada Waterproofers to anyone who needs waterproofing for their home. Since they couldn’t bring heavy machinery inside, they dug almost 7 feet down by hand and still completed the job in an unbelievable timeframe—with no mess and no issues.

My husband and I were really worried about water in our basement. After every big rainfall, we’d find puddles and damp walls. It was starting to feel like a losing battle. A friend recommended Canada Waterproofers, and honestly, they were a blessing. They checked everything and explained the issue in plain words. We ended up getting interior basement waterproofing and a sump pump installation. The crew was polite, respectful, and cleaned up after the job. It’s clear they’re not just any waterproofing contractor—they actually care about doing it right. It’s been dry ever since. No more panic during storms. If you need wet basement repairs, we highly recommend them. They gave us real peace of mind.

We were so tired of dealing with leaks every time it rained. After talking to a few companies, we went with Canada Waterproofers—and I’m so glad we did. These guys are true basement waterproofers who actually know what they’re doing.They helped us with waterproofing basement walls from the outside, and the whole exterior basement waterproofing process was smooth and well explained. They even suggested installing a backwater valve to prevent any sewer backup—and thank God they did, because two weeks later, we had a massive downpour and everything stayed bone dry!Their team made the whole basement waterproofing job feel stress-free. Super professional, honest pricing, and no mess left behind. If you’re looking to protect your home for good, this is who you call.
