Professional Soft Washing Service
Low-pressure cleaning with biodegradable solutions that kill moss, algae, and lichen at the root — the right method for BC's wet climate.
What Is Soft Washing?
Soft washing is a low-pressure cleaning method that uses a biodegradable cleaning solution to kill organic growth — algae, moss, lichen, mildew, and bacteria — before gently rinsing it away. Where pressure washing relies on force, soft washing relies on chemistry.
The solution penetrates deep into porous surfaces and eliminates the microorganisms causing staining and buildup. The result isn't just a surface that looks clean — it's a surface where the growth has been treated and won't come back as quickly. In the Fraser Valley, where properties deal with near-constant moisture from fall through spring, this makes a significant difference in how long the results last.
What We Soft Wash
We provide soft washing service for a wide range of residential and commercial exterior surfaces across the Eastern Fraser Valley.
Roofs
Safe for asphalt, cedar, and metal — no pressure washing that strips granules or voids warranties.
Siding
Vinyl, wood, fibre cement, or painted siding — removes the green film that builds up through BC's rainy seasons.
Stucco
Porous stucco traps moisture and hosts algae. Soft washing cleans it without forcing water into the substrate.
Fences & Decks
Wood and vinyl surfaces cleaned safely — removes biological staining and extends material life.
Soft Wash vs. Pressure Wash
A lot of homeowners use the terms interchangeably, but they're very different approaches — and using the wrong one can cause real damage.

|---|---|---|
| How it works | Low pressure + cleaning solution | High pressure water |
| Best for | Roofs, siding, stucco, painted surfaces | Concrete, driveways, hard pavers |
| Kills organic growth | Yes — at the source | No — removes surface growth only |
| Risk of surface damage | Very low | Higher on softer materials |
| Results last longer | Yes — growth is treated | Growth returns faster |
