High-pressure washing only removes visible mold but leaves spores and root systems that regrow within weeks. Our biodegradable solution kills mold completely for results lasting 1-2 years.
Mold removal doesn't require high pressure. We use under 500 PSI with specialized cleaning solutions. High-pressure washing damages siding, forces water behind panels, and voids warranties.
Vinyl, stucco, Hardie board, wood, brick, and painted surfaces. Each material requires different pressure levels and cleaning solutions; we adjust our method accordingly.
Mold exposure causes respiratory issues and allergic reactions. Our thorough removal protects your family's health and indoor air quality.
Our mold-killing products are safe for landscaping, pets, and Vancouver's coastal environment.
