Problem:  These homeowners had an old sump pump system and pit which was open, creating a humid environment in the home. They were also experiencing some drainage problems and cracks in their basement floor.

Solution: We successfully installed a new SuperSump+ Sump Pump System. We moved the location of their sump pump, filled in the old pit, filled the floor cracks, and improved their drainage system.

We're investigating options to finish our attic, as part of that we want to make sure the space is adequately insulated.
Project Location: Blenheim, ON
Just moved into house march 27th. Since moving their has been quite a few rainy days and today I have noticed that their are a couple spots in the basement that are collecting/pooling with water. I did a quick inspection myself as best as I could and know how and did find a few places where the water appears to be seeping through the concrete foundation itself (no visible cracks from what I've been able to see as some of the foundation is currently behind drywall) as well as maybe water coming in from piping? And or door on main floor that I need to replace. The home has downspouts that go underground (probably a weeping bed) but it is an older home approx 1989 so maybe it wasn't installed properly or the grading is off. First time home owners unsure what to do.

Hi there, I have a back split home, and I am getting water leaking into the basement during heavy rain, and the thaw in early spring. Looking for some quotes on an exterior or interior water proofing plan which could include weeping tiles, re-routing downspouts, and if something you offer, installing a backflow valve. Thank you -Kevin

Just bought a house in July. Was a little damp at times but since middle of October it has constant water flowing across the floor. Looks like it is coming up through the floor more so than down through the walls.

I have a 1939 house, one of the basement wall is leaning in and the one of the walls is bowed it looks like these 2 walls are drywalled where the laundry room is and my other wall is seaping water when I get a bad rainfall and some areas are crumbling, which started when I had 3 trees taken out of my driveway
