Tired of dealing with a damp, moldy crawl space? If your Quebec crawl space has become nothing more than an eyesore, there is a CleanSpace contractor in your area that can help!

A wet, flooded crawl space could cause severe structural damage to your entire house and mold growth may lead to unwanted health issues for you and your family.

One of our Quebec crawl space repair specialists can protect your below-grade space from the elements and ensure a clean, dry, healthy crawl space that can be utilized for storage, instead of becoming wasted space.

    I live in Long Sault Ontario, I was getting the run around with the contractors in Ontario so I decided to get the work done by Systemes Sous-Sol. The workers did an excellent job, I couldn't ask for a better job. Systemes Sous-Sol always kept me updated and they did the job on time and at a reasonable cost. Super Happy customer!!!
