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.

Highly recommend this company. We had a water leak in the basement due to a crack in the foundation, we called for a quote and they came right away and gave a reasonable price. Andrii was very professional and responsive throughout the process. His crew was very skilled and did a good job, found the problem and fixed the leak. The whole team including Carl, Andrii and the crew who did our job were outstanding.

We recently hired Canada Waterproofers Mississauga after discovering major cracks and leaks in our basement walls. They handled everything from exterior waterproofing to a full foundation repair, and the difference is unbelievable. Their crew was kind, respectful, and incredibly professional throughout the entire process.They didn’t cut corners—they used the best basement waterproofing products and truly high quality materials that gave us the confidence our home is now protected long-term. Our basement waterproofing services also included a proper weeping tile system to ensure water drains away from our foundation, and it’s working perfectly.We can finally breathe easy knowing our waterproofing house project was done by a team that genuinely cares. Highly, highly recommend!

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.

I spoke to many companies, some were all about price - trying to be the cheapest provider but lacked a solid reputation, others I felt pushy or had poor communication. I found Canada waterproofers on homestars and it was a great experience. I specifically dealt with Andrew who was knowledgeable, patient and not pushy at all. He came multiple times to have a look and before diagnosing the issues suggested more trouble shooting to be able to understand what the root cause was. Anyhow, his team completed the work all in one day and was very neat And tidy. I got progress pictures throughout and was not asked for any money until I was satisfied with all the work done. This is how you know you’re working with someone who stands behind their work! Their work came with a lifetime warranty for leaks on the wall where they did the work! Thank you Andrew for your professionalism, communication and putting your customer first! Highly recommend you guys

Outstanding company and top quality work.I have never had major structural repairs done to my home and was nervous when I needed a foundation crack repaired. I shouldn't have been. Canada Waterproofers put me at ease from the beginning. Assessment and scheduling was easy. The work was done very fast and with absolutely no damage to the backyard grass and fencing. The quality of work was outstanding and matched exactly the quote. There were no hidden fees or overhead on the invoice.Overall, I am very satisfied and would recommend Canada Waterproofers!

Slava and his team came in, gave a fair price and did the job on the day they said they would. They were quick. They had to dig a trench through the concrete in the basement and when they were done, they cleaned up so all you could see was the fresh concrete. Strongly recommend.
