Your Home faces Water Damage

1. As the snow melts and the rain falls flash flooding near your home can become a serious concern.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

    Lana C. of Gatineau, QC

    Customer Testimonial

              Yes, we were very impressed with Systèmes Sous Sol’ professionalism, the letter beforehand outlining our responsibilities, precautions to be taken, etc. The book you sent ahead of time to help us know the company, possible solutions to the issues homeowners face was very well done. As a former graphics designer, I was impressed. It’s pretty scary when as a homeowner you experience leaks in your home (small or large) and companies you call for quotes don’t respond, yet you can’t move forward as was our case. The laundry room and adjoining bathroom are in their original state (53 yrs.old) needing to be renovated but having to deal with water infiltration every few years. Hi again, I forgot to mention the prompt service we received from Sam. When I had questions, he responded very quickly. He phoned us the night before and that morning too because he was going to be a bit late. He did a great job! Now we can move forward knowing that the problem was resolved thanks to your company.
