House Washing

The problem

The dark streaking under your eaves and the green tint on the shaded side of the house aren't dirt — they're organic growth, and rinsing doesn't remove them. They come back faster each year because what's left behind keeps growing. On the Peninsula, north-facing walls and anything under tree cover go first.

Why soft washing, not pressure washing

High-pressure washing can force water behind siding, strip paint, etch stucco and blow out old caulking around windows and trim. Soft washing uses low pressure and a cleaning solution that breaks down dirt, algae and mildew chemically, then rinses gently. It's more effective on organic growth and it doesn't carry the damage risk.

Every siding type is different

Stucco is porous and absorbs water. Vinyl has overlapping panels that trap water forced behind them. Wood and cedar can splinter and lose stain. Fiber cement handles more but still doesn't need blasting. We adjust pressure and solution strength by material rather than running one setting across the whole house.

What's included

All exterior siding surfaces, trim, eaves and soffits, entryways, and ground-level buildup around the foundation. Light fixtures, exterior doors and window exteriors get wiped down as part of the job — the details are usually what people notice.

How often you'll need it

Once a year for most Peninsula homes. Homes under heavy tree cover, on shaded lots, or in the fog belt closer to the coast often benefit from twice a year to stay ahead of regrowth.
