Professional Crawlspace Care in Coquitlam

Coquitlam's topography is dramatically varied — from the near-flat Como Lake area and the Burquitlam lowlands to the steep slopes of Burke Mountain, where residential development has pushed into terrain that was forestland a generation ago. This range means crawlspace conditions are highly site-specific. Burke Mountain homes on new lots sometimes deal with cut-and-fill grading that has disrupted natural drainage patterns, directing water toward foundation walls in ways that were not anticipated during construction. Lower Coquitlam properties in areas like Burquitlam and Maillardville deal with the older housing stock that characterizes the lower Fraser Valley — vented crawlspaces, original fibreglass insulation, and moisture damage that has accumulated over decades.

Maillardville in particular has some of Coquitlam's oldest residential housing — a French-Canadian community established in the early 20th century, with some properties dating back to the 1910s and 1920s. Crawlspaces in homes of this age have often had multiple rounds of insulation and vapor barrier work over the decades, and we frequently find layers of materials installed by successive owners, some of which have contributed to rather than solved the moisture problems. Proper remediation in these cases requires understanding what is actually there before proceeding with a new approach.

The Austin Heights and Coquitlam Centre areas represent mid-century development — 1950s through 1970s — where many homes have crawlspace foundations and the typical moisture and structural issues of that era. We see a high proportion of cases here where the original fibreglass insulation has completely failed and mold on the subfloor underside is well-established. Encapsulation combined with mold remediation and insulation replacement is the standard scope for these properties.
