Mold Remediation
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.
Mold in a crawlspace is far more common in the Lower Mainland than most homeowners realize. The combination of high annual rainfall, cool soil temperatures, and the older vented crawlspace designs found throughout Surrey and Langley creates near-ideal conditions for mold spore germination. Once wood framing reaches sustained moisture content above about 19 percent, various mold species — including Stachybotrys (black mold), Cladosporium, and Penicillium — can establish colonies on joists and subfloor sheathing within days. Left unaddressed, those colonies degrade structural wood, release spores into the living space above, and contribute to persistent musty odors and elevated indoor VOC levels.
One point that often surprises homeowners: mold does not go away on its own, and painting over it or applying bleach to crawlspace framing does not constitute proper remediation. Bleach is largely ineffective on porous wood because its active chlorine dissipates before penetrating the surface, leaving the root structure of the mold intact. Proper remediation requires physical removal of the colonized material combined with a professional-grade biocide or encapsulant rated for crawlspace use.

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.
