Your basement may be showing signs of water intrusion if it feels humid, produces a musky/moldy smell, or visible moisture spots. These signs are more common in spring and fall as rain water and snow runoff create water pools underneath and surrounding your home. Under the right conditions, the water pools build up pressure and permeate concrete, sometimes causing cracks or visible moisture spots.

Interior Waterproofing – Protect Your Home from Water Damage

The good news is that these leaks can be prevented with a Basement Waterproofing System. The membrane is usually installed on the exterior of the foundation but can also be applied on the inside of the basement. There are also additional measures that can be taken to foolproof the basement by creating underground channels for water runoff.

Key Services Offered

Interior Waterproofing and Crawl Space Waterproofing


While many contractors start outside and deal with the exterior, at Canadian Rooter we also specialize in interior and crawl space waterproofing. This allows us to work from the inside of your home with much less excavation and heavy work, while still providing long-lasting protection from leaks and damp.

Foundation Crack Repair and Under-Slab Drainage


We address cracks in the foundation by sealing them properly and, if necessary, implementing under-slab drainage solutions. This prevents water from seeping through the walls or floors of your basement, protecting your home for the long term.

Sump Pump Installation and Vapor Barriers


Sump pumps remove water that collects beneath your basement floor, while vapor barriers keep moisture from entering your living space. Both methods are crucial to maintaining a dry and mold-free environment.

In Toronto, interior waterproofing is vital because of the changing weather. Proper moisture control protects your foundation, stops basement flooding, and keeps property values high. By preventing water intrusion and potential mold growth, you preserve the structural integrity of your home. A well-maintained and dry basement also appeals to prospective buyers, enhancing resale value and boosting overall market appeal.

Recent Reviews

Water was coming into the bedroom of my furnished short term rental income property. It was important to get it fixed quickly between guests. I did not want to dig up the front of the house at the beginning of our busiest season. Canadian Rooter responded quickly and gave me the best quote and the fastest service! I picked them from a newspaper ad and was a bit dubious. They did tell me that the best way was to dig from the outside, but I could not do that at this time of year. The crew was great, very clean. Walter, the foreman, kept in communication. They were professional and provided me with licensing papers. The work was done quickly and looks very good. They had to dig down through the basement concrete floor which necessitated removing drywall, studs, insulation. They installed weeping tiles, a strong membrane, redirected a problem drain. They do not replace drywall and studs, etc., but referred me to Ivan, a carpenter/handyman colleague who is doing an excellent job as well. Great service! I would highly recommend Canadian Rooter and will use them again. In my furnished rental business, I am often asked if I know good trades people. I will use this site for referrals! I did not know it existed until now. Thanks a lot!

Very professional and quick! We had a flood in our basement and found out it was the result of sewer back up and foundation leek. These guys came in right away and started working immediately. They were extremely neat and tidy; they showed up at 7:30am and didn't leave until 7pm. There is now no leaking at all and I would very highly recommend using them!

The Canadian Rooter crew came into my house to fix existing waterproofing that was made wrong. Foreman explained to me everything that was done wrongfully, and promised to do the job right and on time. He also understood my situation, and expenses that I had to suffer, and didn't charge me as much, as in other estimates. The guys did their job very professionally; they organized their time properly, and left their place clean after they left. THANK YOU Canadian Rooter!!!

Had a leaky basement that could not be waterproofed from exterior, so I called Canadian Rooter for an interior solution. They answered by questions and came in immediately to waterproof the side of my basement and installed a sump pump. So far so good. Quick and easy and gave me a competitive price as I received three quotes and negotiated price. Very happy with the service. Thanks
