Crawl Space Repair Before & After Photos

This home on SSI was an old cabin with the usual issues; cold floorts, rats, musty smells and rotting rim joists.

Our crawlspace remediation converts old crawlspaces into conditioned crawlspaces; warm, dry, energy efficient, and with much better indoor air quality too. Plus the owner can now use it as a viable storage area!

Our systems come with long term transferable warranties too, so if you're buying or selling your home, know that our crawlspace repair methods are the best on the Island.

This crawlspace on Salt Spring was typical with old batt insulation and rodent issues.  After it was cleaned out and sprayed with Benefect disinfectant as an alternate to laying down CleanSpace. R20 closed-cell spray foam was installed to insulate the space. Poorly insulated crawlspaces allow for condensation to form on the wood framing, which then leads to wood rot, mould, mildew, ants, etc. Closed cell foam is a permanent and seamless vapour barrier and prevents condensation from forming on the rim joists, thereby preventing wood rot.

Encapsulation and insulation in crawlspace.

This crawlspace had very high moisture levels, rim joist rot, excessive mould. We stopped the moisture problem, got rid of the mould, fixed the rotting issue and the homeowner now has a clean, dry and healthy crawlspace and home!

This crawlspace was a typical 1970s construction; concrete skim coat on top of a poorly install poly sheet, exterior vents, and the insulation was minimal at best. The rim joist cavities did not have any insulation, air barrier, or vapor barrier installed. The dampness wicking through the concrete skim coat was condensing on the cold rim joists, which resulted in them rotting out, getting moldy, and interfering with the smooth sale of this home. Island Basement Systems was called to provide a solution once the Home Inspector found the issues during the buyer's home inspection.

Our method of repair was to remediate the crawlspace to prevent this from happening again and to replace the rim joist with new materials.

CleanSpace encapsulation liner to provide a permanent ground seal, Elastochem Extreme closed cell spray foam insulation on the exterior walls, (closing off the passive vents too), new rim joist, and mechanical timed ventilation. Mission accomplished, and the crawlspace is now a conditioned space that is clean, dry, energy-efficient with good indoor air quality.
