Crawlspace Insulation
in Burke Mountain, BC
Burke Mountain is one of the most recently developed residential areas in Coquitlam, with construction ongoing on the steep slopes of Burke Mountain above the existing Coquitlam community. Homes here are built on terrain that was forestland until recently, on soils that are a mix of shallow glacial till and organic forest soils. The steep topography creates significant drainage challenges, and the cut-and-fill grading required on these lots alters natural drainage patterns in ways that can produce unexpected water intrusion for individual properties.
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 Burke Mountain — What We See Here
Because Burke Mountain development is recent, the crawlspace issues we address here are different from the decades-old moisture damage we encounter in older communities. The challenges are more often about site drainage design — fill areas that have not drained as intended, grading that channels runoff toward foundations, and drainage systems that were adequate under normal conditions but overwhelmed during the heavy storms that are increasingly common in this region. Proactive assessment and drainage correction are the right approach for Burke Mountain homeowners.
