Challenge: These London homeowners thought they could seal the issue on their own until they recently noticed they were not properly filled and have been letting moisture in behind the drywall.

Solution: We installed our interior waterproofing system with our in-floor drain, moving any seeping water in the sump pump. We provided these homeowners with a peace of mind by installing our TripleSafe sump pump systems, with three levels of protection, these homeowners are ready for the heaviest rainfall. Finally, our team installed our full height, ThermalDry wall barrier to help reflect heat back into their dry space.

Residential house build in 1968. On heavy rain days, water rises up from the basement floor foundation. It comes through the box that houses the sewer clean-out hatch. Not exactly sure what the problem is. Not sure if weeping tile exists or is blocked. Backyard is on a slope towards the house as well. No sump pump was installed with the original house. Looking for a diagnosis and an estimate please.

I had mould removed from my basement and it was said that water is coming up from the ground.
Project Location: London, ON
Moved into the house in late spring of 2024 knowing the basement was going to be a project. Seeking a quote to use on greener homes lone and a contractor/company to complete the work. Suggestions from our energy assessment are to insulate the foundation. The unfinished basement has experienced minor water leakage this summer and some wear on the foundation is apparent. 1950s build, basement is approx. 540sqft. The expected project is to upgrade the basement space by firming up the foundation, waterproofing and insulating the space.
