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.

Hi! We purchased our first home 2 weeks ago and there's water in the basement 🙁 we know there was a small leak somewhere but assumed it was the old windows down there. Since moving in, we've pulled back some panelling to see and discovered large cracks. This is all very new to us. Is there someone who would come out and provide a free estimate? Or what is the cost involved to have someone come out and give a quote? Thanks so much Ashley
