Mold Removal & Remediation in Coquitlam, BC

Burke Mountain is a specific hotspot for attic mold in newer Coquitlam homes. Townhomes and single-family builds from 2010–2018 frequently have bath fans that were installed to terminate inside the attic, and ventilation baffles that weren't installed correctly. We've assessed a significant number of Burke Mountain homes with attic mold colonies under 10 years old.

Ranch Park and Austin Heights crawl spaces from the 1960s–70s are some of the most common calls we get from Coquitlam. Original vapor barriers in this era were either 4-mil poly (now typically brittle and torn) or simply absent. The floor joists, sill plates, and rim joists in many of these spaces have had decades of ground moisture exposure.

Maillardville's older homes and the heritage-adjacent stock in the lower Coquitlam townsite frequently have basement moisture issues from aging drainage and foundation walls that weren't waterproofed by modern standards. Westwood Plateau homes on steep terrain can have exterior drainage that routes water toward the foundation during heavy rain events.

Pre-purchase mold inspections are common in Coquitlam, particularly for Ranch Park and Maillardville homes where buyers are savvy enough to know the age-related risk factors. We also do a significant number of inspections for Burke Mountain buyers and sellers — it's become an expected part of transactions in that area given the known attic mold issues.

Coquitlam receives significant rainfall and has many properties with heavy tree canopy that deposits debris on roofs and in gutters. Blocked gutters overflow and allow water to enter at fascia and soffit — a path that can saturate attic insulation before anyone notices. We see post-roof-leak mold calls from Coquitlam regularly, particularly after autumn storm events.

Burke Mountain townhomes with bathrooms that share exterior walls and inadequate exhaust ventilation — a common construction pattern — develop bathroom mold more quickly than detached homes. The shared wall assembly doesn't allow moisture to dissipate as easily.

Coquitlam's real estate market is active and buyers and their agents increasingly request clearance certificates after remediation — particularly on Burke Mountain and Ranch Park properties where attic and crawl space mold are known issues. We coordinate independent testing that produces certificates lenders and buyers accept.
