Crawlspace Encapsulation
in Murrayville, BC
Murrayville is one of the older established communities in Langley Township, with residential streets dating from the mid-20th century and a character that reflects its origins as a rural village centre. The homes here range from original farmhouses and small-town bungalows from the 1940s and 1950s to post-war suburban homes from the following two decades, with crawlspaces that represent the full range of construction practices of those eras.
Crawlspace encapsulation is one of the most effective investments a homeowner in Surrey or the broader Lower Mainland can make. The process involves covering the crawlspace floor and walls with a continuous, heavy-duty polyethylene vapor barrier — typically 12-mil or 20-mil reinforced poly — then sealing every seam, penetration, and vent opening with industrial-grade tape and adhesive. The result is a fully conditioned environment that is physically isolated from ground moisture and the damp Pacific Northwest soil beneath your home.
The installation process begins with a thorough cleanup — removing old fiberglass batt insulation (which absorbs moisture and harbors mold), clearing any debris, and treating visible mold colonies. Technicians then install the vapor barrier across the ground, lapping it up the walls and piers, and sealing it to the stem wall with adhesive and mechanical fasteners. All vents are closed and sealed from the inside. Depending on the space, we may also install a commercial-grade dehumidifier calibrated to maintain relative humidity around 50 to 55 percent throughout the year.

About Murrayville — What We See Here
Older homes in Murrayville sometimes have crawlspaces with original construction details — wood posts on concrete pads without protective post bases, original cedar or fir sill plates that have been exposed to decades of moisture, and foundation wall construction that predates modern drainage requirements. We approach these properties with care, assessing what original elements can be preserved versus what needs replacement, and designing modern moisture management solutions that work with the existing structure rather than requiring extensive demolition.
