Basement Waterproofing

Our comprehensive basement waterproofing solutions protect homes from water intrusion using advanced exterior and interior methods. We address foundation cracks, hydrostatic pressure, and damp conditions through proven techniques like Hydro Guard membrane application and drainage system installation. Services include lifetime warranty coverage and tailored solutions for both new constructions and older homes facing water damage challenges.

Foundation Repair

We specialize in foundation crack repair and structural stabilization using epoxy injection and engineer-approved reinforcement techniques. Our services address freeze-thaw cycle damage and foundation movement issues while ensuring long-term structural integrity for residential properties across diverse soil conditions in Ontario.

Sump Pump Installation

Professional sump pump installation and maintenance services protect basements from flooding with battery backup systems ensuring continuous operation during power outages. Our solutions include proper sizing, strategic placement, and integration with existing drainage systems for optimal water management in varying climate conditions.

Crawlspace Encapsulation

We transform moisture-prone crawlspaces into dry environments using vapor barriers and encapsulation techniques. This process prevents mold growth, improves indoor air quality, and protects structural elements while addressing humidity-related issues in residential properties throughout Ontario's climate zones.

Interior Waterproofing

Our interior waterproofing systems combat existing moisture problems through internal drainage management and wall sealing techniques. This approach effectively handles hydrostatic pressure issues in Ontario's varied soil conditions while minimizing disruption to finished basement spaces and existing landscaping.

Kurt came to the house and inspected our leaky basement. He discussed our options, what had to be done to fix the problems. One the day of repair, Omar and his crew arrived on time, explained exactly what they would be doing, were courteous and respectful. They worked so hard all day. It was a cold and snowy day, they completed the whole job in one day. Clean-up was excellent. What a great crew. Thank you.

The crew of Canroy and Mauro was very professional and personable. They arrived on time and assessed the work that needed to be completed. The work was completed expertly, efficiently and neatly. There was virtually no clean up needed on my part. The only way I knew they were there was because the damage had ben fixed. I have already referred them to friends and family and would highly recommend. You will not be disappointed!

RCC did an amazing job waterproofing both the inside and outside for our basement. Mauro has all the answers to our questions and provided us with the best quotation for the work that was required. He was always available by email and by phone to help.
Noel and his crew were absolutely a pleasure to work with. Professional, meticulous in their set up, execution and clean up. Incredible workmanship! Highly recommend RCC and Staff to any one needing their services...the best in their field!

Contacted RCC about waterproofing my basement foundation walls as I had some water issues. From the 1st contact through the entire process the team at RCC took care us. Ramy was great at communicating the quote and the aspects of the job. Andy & his team showed up on time and completed the work without issue. The guys explained how a previous waterproofing job was poorly finished (side of the house had been waterproofed and the weeper was not connected) and explained how their lack of detail contributed to the problems that I was having. He explained how they fixed it and that it should never have

I had a great experience with RCC. It was for my grandfather's house. My estimator Mauro was very kind, and took the time to explain to him and I the problem. RCC came and did a thorough job. They came in and did what they had to do, and left with no mess. It was professional and efficient. There was a re-leak but they honoured their lifetime warranty, came back to do water tests and fixed the problem. I would recommend RCC as they are a trustworthy company, very professional, and have great representatives working for them.
