Crawlspace Insulation
in Richmond, BC
Richmond sits on Lulu Island and Sea Island in the mouth of the Fraser River, which means it occupies some of the lowest-lying land in Metro Vancouver. Much of the municipality sits at or below sea level, held above water by an extensive dyke system. For homeowners with crawlspace foundations — common in the older residential areas of Steveston, Brighouse, and the City Centre neighbourhoods — the water table is a constant consideration. In many areas of Richmond, the water table is within two to four feet of grade year-round, and it rises higher during wet periods. A vapor barrier alone is insufficient in these conditions; active pumping through a properly sized sump system is generally required to keep crawlspaces dry.
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 Richmond — What We See Here
The soils beneath Richmond residential areas are predominantly marine and riverine sediments — silts and fine sands that are highly compressible and have relatively low bearing capacity. This has implications for structural support: post footings in older crawlspaces may have settled significantly over the life of the structure as the underlying soil compressed. We frequently encounter original wood posts in Richmond crawlspaces that appear to be in reasonable condition but are sitting on footings that have dropped an inch or two below their original elevation, creating floor deflection above. Combining structural correction with encapsulation is common in this community.
Richmond's newer developments built since the 1990s are generally on concrete slab foundations rather than crawlspaces, but there remains a significant inventory of older homes — particularly in Steveston and along the Richmond City Centre area — where crawlspace services are needed. We have extensive experience with the specific drainage and moisture management challenges that Richmond's geography presents.
