Mold Remediation
in Clearbrook, BC

Clearbrook is one of the older residential communities in Abbotsford, developed as a distinct Mennonite farming settlement before being absorbed into the modern city. The residential areas of Clearbrook have housing stock from the 1950s through the 1970s on relatively flat terrain with heavy clay soils — conditions very similar to the older Fraser Valley communities we serve throughout the Lower Mainland. Crawlspace moisture and mold issues are common in this housing stock, which was built to the standards of its era.

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.
