In Coquitlam, rain and moss buildup dull siding fast. This page covers safe cleaning methods for vinyl, fiber cement, and wood siding. Learn what to expect from professional service. Protect your home’s value with proper exterior maintenance.
Homeowners in Coquitlam often see green algae and black streaks on north-facing walls. These stains show up quickly in the coastal climate. Moisture sits on exterior surfaces for months at a time. Soft washing uses low-pressure rinse with biodegradable cleaners. This removes dirt, mold, and mildew without damaging siding material or paint.
High-pressure washing forces water behind siding panels. This causes warping or cracking that leads to expensive repairs. The method works well for concrete driveways. It destroys the protective finish on exterior walls. Burke Mountain homes with cedar siding benefit most from gentle technique. This preserves wood grain and factory coatings.

It breaks down organic growth at the molecular level. This approach removes years of buildup. It also protects the structural integrity of siding materials.
Most Coquitlam homes need siding cleaned every 12 to 18 months. This maintains curb appeal and structural protection. BC’s wet climate speeds up moss and algae growth.
