Check out this Saltspring Island crawlspace! From rodent-infested, musty and just plain nasty to clean, energy efficient, dry and even pleasant to look at!
Exterior retrofit before/after:
This Prospect Lake home had a mould problem on the interior due to the poorly insulated walls. Every winter, condensation would form on the cold walls, leading to a pretty nasty mould issue. In 2009, the owner had enough and the house was retrofitted. To repair the home, the walls were retrofitted by removing the batt insulation from inside and adding R13 of open cell foam. Then we added an exterior layer of R18 closed cell foam, along with a rain screen system and new Hardie Plank siding. Now the walls are R31 rated are completely air tight! The roof was re-insulated as well with an exterior layer of closed cell foam, and new sheathing and shingles to complete the package. A true deep retrofit that also score 84 on the EnerGuide rating.
For this project, we started with the foundation repairs, and eventually solved the entire homes energy efficiency issues.
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.
Perimeter drains should be replaced every 25-30 years. Our alternative solution for this site is to install our sub-slab WaterGuard and SuperSump system under the basement floor as this will prevent seepage and flooding from occurring without the cost and mess of digging up the front yard. Also removing and replacing the basement slab is very difficult and expensive. Our solution to stop water vapour we use ThermalDry membrane flooring that is both a vapour barrier and a thermal break so the basement is more comfortable.
Closed cell spray foam is perfect for basements and can be tied into the ThermalDry flooring membrane to provide an encapsulated basement. It's seamless bonds well the the concrete and wood framing, providing a complete air barrier as well as 20 insulation.
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!
