Crawlspace Insulation
in Burnaby, BC
Burnaby's topography ranges from the relatively flat areas along the Burrard Inlet waterfront through the mid-slope residential neighbourhoods of Capitol Hill and Burnaby Mountain to the lower-lying districts around Edmonds and Metrotown. The variability in elevation and soil conditions means crawlspace challenges vary considerably across the city. Properties on Burnaby Mountain and Capitol Hill often deal with steep-site drainage challenges, where surface water moving downslope through clay soils is channelled toward downhill foundation walls. Properties near Deer Lake and in the lower Edmonds area face a higher seasonal water table.
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 Burnaby — What We See Here
Many of Burnaby's established residential neighbourhoods were built in the post-war era through the early 1970s, and a significant proportion of this housing stock has crawlspace foundations. These homes are now old enough that original structural wood — posts, beams, sill plates — has had decades of exposure to whatever moisture conditions were present before the first renovations or repairs were done. In our experience, Burnaby homes from this era are among the most likely to have multiple compounding issues: deteriorated original posts, collapsed insulation, and mold on the subfloor underside that has gone unnoticed for years.
The good news for Burnaby homeowners is that the soil conditions in most of the city, while clay-heavy, respond well to proper perimeter drainage improvements. Combined with encapsulation, these interventions tend to produce very effective results. We also note that Burnaby has an active real estate market, and crawlspace conditions are increasingly part of pre-sale and pre-purchase inspection discussions — a clean, documented, encapsulated crawlspace is a measurable asset in the market.
