Many older homes in Langley, Brookswood and Aldergrove sit over crawl spaces, and our wet winters keep the ground under them damp for months. A crawl space vapour barrier stops that moisture rising into the space, protecting floor framing and keeping rooms above warmer and fresher. If your barrier is missing, torn or stops at the floor, it’s time for an upgrade before the coldest weather arrives. Get our crawl space vapour barrier tips for Langley homes.
