Larry B. in Welland, ON has a house with a nasty crawlspace. Despite efforts to insulate and encapsulate himself, the crawlspace was still cold and damp. This caused problems with the floor joists sagging and cold floors upstairs. Omni Basement Systems recommended a 3 part system for Larry. Add supplemental beam and Smartjacks to fix the sagging floors, Silverglo Insulation on the walls to keep the crawlspace and floors warm and finally, encapsulate the crawlspace with Cleanspace membrane. Cleanspace is 20mil thick liner with cord reinforcing and antimicrobial product built right in. Cleanspace is mechanically fasten so it will never come off.

Good day... I have a wartime-era house, with a crawlspace. In one quadrant of the main floor [my office area], I am suffering from what your website describes as an "Uneven, bouncy or sagging floor". Before I continue with any further renovations and upgrades, I felt it to be a good idea to have it looked at, and plan what my next steps should be. Thank you for your time,

The front entrance of my house is settling. There is also a crack on the inside of the house in the corner of the wall. I'd like to repair it before any damage happens!
