I have to say that I had a difficult project due to the area that is full of large stones to put the ties in and the tight space between the house and the fence, that increase the difficulty of this project for putting the French drain along the house ; we had to impliment plan \"B\", do the French drain from the inside of a crawl but the finish product was great.

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.

I contacted Systemes Sous-sol in April/2021 via the internet and quickly received a reply from their office in Laval through which I booked a free inspection and estimate with Jerry Evangelatos, System Design Specialist for April 5th, 2021.  Mr. Evangelatos drove to Wakefield, Quebec and sat down with me to fully explain the "Dry basement solution". His presentation was clear and precise and provided full details of the systems, the cost, the time for the work. the lifetime guarantee and the preparations required. I had read the complete booklet sent to me earlier but Jerry showed me an additional video of the work to be done and with all of this information. I was able to make a decision immediately after I fully understood this system. He was able to give me the date of April 29 for the installation.  Later, I received a call from Valerie, who was pleasant, professional and enthusiastic and who offered me an earlier date. After confirmation with my plumber, I was able to accept this new appointment.  On Tuesday, April 19th, two company employees arrived, having called me to inform me when they could get here. I was very impressed with the friendliness and professional manner of Felix, who was obviously perfect bilingual, very competent and very comfortable with people. When he and his fellow Worker, Quan, arrived, they spent some time with me in the basement going over the work that would be done, the estimated time it would take and offered to respond to any questions. Felix reviewed the contract I had signed with Jerry and then set about their work.  I have never seen two men so motivated, so knowledgeable and so willing to do this job as efficiently and carefully as possible. They were both respectful of me and my home and did their work with as little disruption as possible. They worked as a team and obviously knew what needed to be done and how the best to do it. Felix kept me informed with regard to their progress and always asked whenever he needed to use an indoor plug or whatever. I have already spoken to friends and neighbors about the quality of the workmanship and the integrity that both Felix and Quan demonstrated throughout the 3 days here in my home. They worked together tirelessly and rarely if ever stopped for breaks.  Felix was extremely professional and knowledgeable and though, obviously in charge, treated his coworker with respect at all times. Quan worked comfortably alongside Felix, and both of them worked with amazing strength and speed and wasted no time in bringing the job to completion in a timely manner.  I have never been so impressed by two young men who are obviously both loyal employees, promote their products with confidence and respect and are wonderful ambassadors for your company and worthy of my respect and admiration.  I compliment the entire company on its successful completion of this contract.  Sincerely,

It is been over one year since we purchased this wonderful system, and with all the rain we've been having this week, I felt compelled to write to you.We lived in this house with a leaky, smelly, often flooded basement for years! Since installing your system, we have not had one drop of water downstairs and my home no longer smells like wet socks. Everytime we have a large rainfall, I reflect on how happy I am that we chose Basement Systems Quebec. I love my super-sonic sump pump so much, I refer to it as "the sump pump that God made". We have done extensive renovations over the last two years, and as much as I enjoy my lovely new kitchen, etc. nothing compares to how much I love my dry basement! It has eliminated so much stress for us to know that we can be away for a weekend or expect a heavy rainfall without worrying about whether or not our stored items are floating in 3 inches of water...and the days of mopping, shop-vaccing and trying to bleach out the smell and mold are long behind us!Please continue to use me as a reference for your company, as I have been 100% satisfied with your product, your workmen, and your service since the moment you arrived in our home.Thanks again for a great job!Warmest regards,Mrs. Plymale

    Mrs. Cuff wanted like to use her crawl space for storage, but it was very humid. Since she wanted to keep her belongings in good condition and avoid mold, she wanted to find a solution. So, she decided to contact Systèmes Sous-sol Québec in order to resolve the humidity problem quickly.

     

    The solution for our client was to first install a SmartSump sump pump system. It is connected with a discharge line which will expel the water away from the foundation of the house. Then, a drainage mat was placed on the ground so that the water that ends up on the surface goes directly to the SmartSump. Finally, our CleanSpace coating is installed over the drainage mat. Material with a thickness of 20 mm composed of polyethylene and antimicrobial, it blocks moisture from the soil and prevents the proliferation of mold. It also gives a clear and bright appearance to the crawl space.

     

    With this solution, Mrs. Cuff will be able to use her crawl space as storage space and above all have a dry crawl space!

    Our clients in Gatineau were suffering from water infiltration problems in their home's basement which caused humidity in the area and has also lead to severe coldness in the basement that has reached the whole house as well.

    As you can see in the first picture, the water has penetrated the floors and structural paint damages have occurred on the walls.

    Furthermore, our professionals have installed a WaterGuard system, our SuperSump sump pump, as well as our SaniDry and IceGuard systems and finished it with the EverLast wall restoration systems.

    Our clients are now very happy since they did not face any humidity problems again and can enjoy their new warm, dry and beautiful basement.

    Installation of a vapor barrier and a sump pump in a crawl space in Gatineau, Qc

    The problem

    Mr. Sirois noticed a high humidity in the house, cold air on the main floor coming from the floor and some places of the hardwood floor on the main floor was no longer at level. The cause was the humidity in the crawl space. He contacted Systèmes Sous-sol Québec to add a good vapor barrier membrane, clean the crawl space to improve air quality and reduce the humidity.

     

    The solution

    Adding a SmartSump sump pump system, a drainage membrane and CleanSpace vapor barrier. Most of the moisture in the crawl space comes from the earthen floor that contains water and it can come also from the walls. The SmartSump will therefore be able to remove water from the ground outside and away from the foundation. The drainage membrane, on the other hand, is placed on the ground and makes it possible to drain the water that is on the surface towards the sump pump system. The CleanSpace coating which acts as a vapor barrier is placed over the drainage membrane and blocks moisture from the ground.

    This client had cracks repaired in one wall of his block foundation, but had not repaired all of the walls. Over time, one of the walls will start to arch and tilt inward from the basement. If nothing will be done, the situation will only get worse. So, he contacted Systèmes sous-sol Québec in order to stabilize his wall once and for all!

    Mr. Woods has an earthen crawl space with several problems:

    - Water infiltration

    - Humidity

    - Mold

     

    When it rains or during spring, water infiltrates in his crawl space creating a lot of humidity and mold over time. Another source of moisture is the earthen ground. The water in the soil evaporates creating moisture.

    All of This has affected the comfort of his home, as his floors were cold and there was a smell of dampness in the house.So he contacted Systèmes Sous-sol in order to isolate his crawl space and resolve his problems definitively.

     

    The solution

    First, the mold on the wooden walls was removed with our Mold-X product. Then, our experts installed our SilverGlo insulation panels on the walls of the crawl space. 2 '' thick panels with radiant barrier to isolate the cold and reflect heat inside the crawl space. They then laid our TerraBlock insulation sheets on the earthen floor. They made it possible to insulate the crawl space and protect it against humidity. Finally, our experts installed our CleanSpace coating on top of the TerraBlock. Moisture is therefore blocked, it protects the TerraBlock insulation sheets and crawl space into a clear and clean appearance.

    This is another crawl space that was suffering from water infiltration.

    When water had invaded the place, it had affected badly on the floors in too many areas, causing it to sag. 

     

    We have solved this crawl space problems by installing a drainage membrane on the floor to help water find its way to the drainage system. Then, we covered the floor with a CleanSpace membrane, which mainly serves to prevent water vapor from leaving the floor and rising to the upper floors. Next, we installed SmartJack systems, which are galvanized steel beams used to support the sagging floor. Finally,we had installed SmartDrain drainage systems, which are used to get rid of infiltrating water.

    Now that our work is done, the place is completely encapsulated!

Our crew then proceeded to install a CleanSpace membrane, a SmartSump pump system, and two SmartJack support pillars. They also applied Mold-X Neutralizer to areas affected by mold. Our customer can now enjoy her basement without having to worry about water getting in!
