We have transformed this crawl space in Dunham, Qc into a very beautiful area.

The soil was very wet, mold and insects were growing.

So we installed our CleanSpace membrane to insulate the house from the ground and our company’s SmartDrain that intercepts water infiltration caused by plumbing leaks.

Installing a vapor barrier will entirely seal and encapsulate your crawl space. This prevents moisture from entering the space, therefore stopping mold growth, and will keep out pests as well.

We have successfully installed one of our top sump pumps in Dunham, QC called the TripleSafe pump. Sump pumps systems gets rids of water before it seeps into your place and causes flooding and damage.

All the water intercepted is evacuated far from the house. The TripleSafe system gives you three times more protection thanks to its three pumps. The first allows pumping water under normal conditions. The second embarks when the flow and / or the volume of water is too fast. The last is a pump that works thanks to a self-recharging battery. This pump will save your basement if a storm or other reason causes a power failure

Our client was the new owner of this home. She quickly noticed a moisture problem, not knowing the source she called our team for a quote.

The team realized that this moisture was coming from the crawl space. They also found water infiltration on the upper floors. A complete solution with the CleanSpace, the SmartPump, an IceGuard and a LawnScape will guarantee a dry and usable crawl space.

Our Supersump pump system is being considered as one of the best pumps in the market; it has an airtight lid on it to prevent water from evaporating out of the sump hole into your basement, to stop stuff from falling in, that can clog the pump or switch, and to quiet the system.

Job Stories From Dunham, QC
Moisture problems in crawl space, Dunham, QC

Mrs. Élaine has bought her house only a few months ago and she immediately realized the problem in her crawl space; there was a lot of humidity and even water infiltration on the floors. She wanted to fix the problem, before the mold would grow and the mess got even bigger. And she was worried that this would affect her investment and affect the rest of her house. She therefore decided to act quickly and contact us, knowing that we were experts in this type of work.

Therefore Mrs. Élaine chose a perfect complete solution for this type of problem including several products.

We started with the CleanSpace product. This is a crawl space encapsulation’s solution, which is the best choice for reducing moisture from soil. This product prevents mold from getting to floors, through floors and walls.

Then she chose the SmartPump (with an IceGuard and a LawnScape). The SmartPump is a crawl space drainage system that keeps your crawl space dry with its state-of-the-art pump. This creates a perfect seal around the CleanSpace coating.

And here is another successful job executed by our team in Quebec!

Moisture and mold problems in a basement in Dunham ,QC

Mr. Frederic who lives in Dunham, Qc, had asthma problems and his doctor informed him that he needs to stay in a completely dry place, or else his health issues will get worse.

Living in that house was not helping Mr. Frederic’s issue, since he felt that his house had lots of moisture and started questioning the reason behind this.

When he started asking about that problem, our client found our company, and he contacted us in order to get more details, and asking us whether we can inspect his place.

We were happy with our client’s trust and we informed him that our inspection if for free!

As soon as we got there, our foreman Paul saw many signs of humidity presence such as mold existence and water seepage, and suggested a complete waterproofing system.

The waterproofing system consisted of an Interior drainage system ‘ WaterGuard’ that  captures all the water infiltrating from the floor and walls and redirects them to one of the best pumps available the ‘TripleSafe’ pump system.

The TripleSafe system that we installed gives you three times more protection thanks to its three pumps.

Finally we installed the CleanSpace vapor barrier which is an ultra-resistant vapor barrier specifically designed to block water vapor, preserves the structure of the house and prevents mold from growing.

After months from the installation, our client’s health got so much better and he never had any water issues in his basement ever again!

Moisture problems in a crawl space in Dunham, Qc

This crawl space in Dunham Qc, was in a very bad condition. A lot of water was seeping into the place, which was humidifying the air and adding mold and bacteria into it.

Mrs. Elaine tried several times to fix this problem but moisture never stopped, until she found us and contacted our team asking for our help.

Our company encapsulated this crawl space by installing a CleanSpace membrane which is designed to create an ultra-resistant barrier against moisture, preventing mold growth. This product is guaranteed for 25 years against tear.

Then a SmartSump pump was installed to intercept water infiltration. This system is especially designed for crawl spaces.

After the installation, the crawl space looked so bright and clean and our client’s place never had humidity ever again!
