Before and After Pictures from Blenheim

Before After

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 own a house in Blenheim and we are looking to fix up our basement / crawl space area - most of the house is crawl space and 1 small furnace room in about the middle of the house. There has been water in the basement and we aren't sure if we need to waterproof it from the outside or inside and I believe our sump pump isn't working well. The crawl space we would just like to clean everything up and insulate it. Please let us know what you suggest. Thank you, Aggie

Radon Mitigation. Seems like a pretty simple procedure to be done in my basement. I have tiling in the inside of the house underneath the concrete that leads back to the sump pump room.
Project Location: Blenheim, ON
We are planning to replace our back deck this summer and have a few minor cracks in our block foundation (open/exposed in the basement). Our house was built in 1980 and the foundation was never sealed. We are looking to get the back (26ft in length) of our home dug and waterproofed/sealed before we proceed with putting up a new deck. We are looking for a quote on this work. Thank you!
