House Washing — Richmond BC

Soft Wash Exterior Cleaning for Richmond Homes

Richmond's coastal climate — over 1,100mm of annual rainfall, persistent humidity, and dense residential tree cover — creates ideal conditions for algae, mildew, and moss to establish on siding. Left untreated, biological growth traps moisture against your siding surface, accelerating paint failure and, on wood or composite materials, the degradation of the substrate underneath.

House washing removes this growth before it causes structural damage, restores original colour, and significantly improves curb appeal. We use soft wash — low-pressure application with surface-appropriate cleaning solutions — rather than high-pressure washing, which can strip paint, force water behind cladding, and damage seals around windows and doors.

Surface-Matched Approach

Every siding material requires different chemistry and pressure. We assess the surface before treating it.

• Vinyl siding — soft wash with low-concentration SH; no mechanical scrubbing that leaves swirl marks
• Stucco — soft wash only; high pressure cracks stucco finishes and forces water into the substrate
• HardiePlank (fibre cement) — soft wash; protects the paint finish and factory sealing
• Cedar and wood siding — low-concentration treatment to kill biological growth without bleaching grain
• Brick and stone — pressure or soft wash depending on mortar condition and biological load

Frequently Asked Questions

How much does house washing cost in Richmond?

Most Richmond homes run $300–$600 depending on square footage, siding type, and storey count. We provide exact quotes after a free assessment.

How often should I wash the exterior of my home?

Every one to two years in Richmond's climate. Homes with heavy tree coverage or north-facing walls tend to accumulate growth faster.

Is soft washing safe for my plants and garden?

Yes. We pre-wet all landscaping adjacent to the work area and rinse after application. The dilution concentrations we use for siding are not harmful to established plants.
