Paint manufacturers require clean, dry surfaces for warranty coverage. Painting over moss, mildew, or chalky residue causes premature failure. Our soft wash cleaning removes all contaminants so paint bonds correctly.
Low-pressure cleaning (under 500 PSI) with biodegradable solutions. Safe for stucco, wood, Hardie board, vinyl, brick, and painted surfaces. Pressure washing can damage delicate siding and void warranties.
Moss, algae, mildew, and mold must be killed at the root, not just rinsed off. Our treatment ensures these don't grow back under new paint within months.
We work with Vancouver painting contractors regularly. We understand timing, surface prep standards, and paint manufacturer requirements.
