Crawlspace Insulation
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.
The majority of homes in Surrey and the surrounding communities built before 2000 have fiberglass batt insulation installed between the floor joists in the crawlspace. When this insulation was new and dry, it provided reasonable thermal resistance. The problem is that fiberglass batts installed in a vented crawlspace environment in a high-rainfall climate like ours rarely stay dry. They absorb ambient moisture, sag out of their cavities, and gradually collapse onto the ground. Wet fiberglass insulation has essentially zero R-value, adds weight that can pull down on vapor barriers or staples, and provides a hospitable nesting environment for rodents.
For crawlspaces that are not being fully encapsulated, we install new unfaced fiberglass batts or mineral wool between the joists, but only after addressing the moisture conditions that destroyed the previous insulation. Installing fresh batts into a still-damp crawlspace environment means you'll be back in the same situation within a few years. Proper sequencing matters: drainage, vapor barrier, then insulation.

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.
