Crawlspace Insulation
in Edmonds, BC
Edmonds is one of the lower-elevation neighbourhoods in Burnaby, situated near the border with New Westminster and occupying relatively flat terrain. The soil conditions here are clay-dominant, and drainage to natural outlets is limited by the flat topography. Like many of Burnaby's mid-century residential areas, Edmonds has significant housing stock from the 1950s through the 1970s where crawlspace conditions have deteriorated over the decades.
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 Edmonds — What We See Here
Mold on subfloor framing is particularly common in Edmonds crawlspaces that we inspect. The combination of flat drainage, heavy soils, vented crawlspace design, and decades of Pacific Northwest wet seasons creates ideal conditions for persistent mold establishment. We address this through comprehensive remediation — mechanical removal of colonized material, antimicrobial treatment, encapsulation, and dehumidification — rather than partial measures that allow recurrence.
