Testimonials from our customers in Oshawa, ON Glenda R. Ritson Road South

Very happy with a dry basement!

Sean S. Jarvis Street

Worked with Mark from Clarke basement systems and he was very professional and helpful with explaining the system they use to waterproof your basement. Dave was my installer and his team was quick and clean, no mess left behind in the work zone and was very easy to work with. If you need your basement to be worry free then this is the place to go to, well worth the investment to never have to worry about the basement having water ingress. Would recommend them to anyone that needs even just a consult as Mark came back twice to make sure I understood the scope of work to be done.

Richelle P. Athol Street East

This is a very professional, organized and experienced company and I highly recommend them

Anand S. Oshawa Boulevard South

Clarke Basement's team is amazing. Very thorough and professional

John S. Hillcroft Street

We have an old home and with all the rain this year we have had a lot of water in our basement. We had several companies come and give us quotes to waterproof our basement and what set Clarke's apart from the other quotes was how thorough their initial inspection was and then how well they explained the process to us. The crew they had was fantastic. They explained what they would be doing day by day and were always on time. The crew was very professional, they kept the mess from their work to a minimum and did an exceptional job. I waited a few weeks to leave a review, and after a couple of heavy rainfalls, I can say we no longer have water in our basement. We are very happy that we chose Clarke's and I would recommend them to anybody needing to get

similar work done.

Based on the suggestion of the installer we soaked the area outside where the injections had been made in the basement walls and there was some remaining seepage. The installer returned and did more injections, performed an additional test and there was no more leakage into the basement. There has not been any leakage since, even after some strong rain storms that have occurred since. Thank you!

I liked how informative Bill Wallis was as to what procedure was needed for the leak issue we were dealing with. The installation person was on time and the clean up was great. I have been recommending Clarke Basement Systems. We have had some huge rain falls since we have had the basement fixed and the basement is dry. Thank you for a job well done and everyone we have dealt with has been pleasant and forth coming with information if needed.

I think we need at least a full calendar year to evaluate if the repair is good.

Job Stories From Oshawa, ON

Oshawa, ON Foundation Crack Repaired with FlexiSpan

Stephen D. of Oshawa, ON noticed that his foundation wall was showing signs of water seepage, manifested in the form of a lengthy wall crack. Worried for the healthfulness of his home, he sought out assistance in fixing this problem, which led him to the talented team at Clarke Basement Systems.

Claude Mathieu met Stephen at his residence to analyze the problem and determine what the best course of action for remediation would be. Claude recommended the FlexiSpan waterproofing system, designed specifically to fix leaks in foundation walls. Primary Foreman Lucio Flores arrived with his crew to perform installation, which took only a single day and required minimal intrusion into the home. Stephen was ecstatic about the finished project, and greatly appreciated the peace of mind that his foundation would remain leak free.
