Crawlspace Insulation
in Coquitlam Center, BC
The Coquitlam Centre area — surrounding the regional shopping mall and extending into the adjacent residential streets — has a mix of housing types from the 1970s and 1980s that represent the period when this part of Coquitlam transitioned from low-density suburban to more urban character. Single-family homes on crawlspace foundations from this era are common in the streets surrounding the commercial core.
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 Coquitlam Center — What We See Here
The soil conditions in central Coquitlam are predominantly clay-loam, similar to other mid-slope communities in the Tri-Cities area. Drainage is better than in the flatland communities to the south but still prone to surface water accumulation after heavy rain events. We work regularly in this area on encapsulation and mold remediation projects for homes that have accumulated moisture damage over the decades of their existence.
