House washing in San Mateo — the green off, the paint on.
San Mateo's housing mix — stucco in Aragon, wood siding in Baywood, mid-century in Hillsdale — is exactly why we don't own a one-pressure approach. Each material gets its own detergent and its own touch, and every house gets the cobweb-and-eaves detail that makes the difference.

Real before & afters from this service across the Peninsula.
House Washing, the right way.
We wash houses with low-pressure soft washing: a material-specific detergent does the work, then a gentle rinse carries the grime away. Stucco, painted wood, fiber cement, and brick each get their own approach — never a one-pressure-fits-all blast.
A full wash covers siding, trim, eaves, and cobweb detail under the roofline. The biological growth dies at the root, so the house stays clean longer and paint lasts longer.
San Mateo specifics: San Mateo runs the full range — downtown bungalows, Baywood and Aragon's tree-lined streets, Hillsdale ranches — and the mix of stucco, wood siding, and older brick keeps every job a little different. We work Baywood, Aragon, San Mateo Park, Hillsdale, and Shoreview regularly.
Four services.
Obsessively executed.
Common Burlingame service calls: moss removal from shaded roofs, brick walkway restoration in Burlingame Park, driveway cleaning in Easton Addition, and gutter clearing across the whole city after the rainy season.

Gutter Cleaning
Gutters cleared by hand, every downspout flushed until it runs clear, and a look at the hardware for sagging, pulled spikes or separated seams. Book before the rains.

- Clogged downspouts cleared
- Damage inspection report
They washed the whole house and nothing was damaged — which was my worry going in. The stucco came out perfectly even.

Asked constantly.
How much does house washing cost in San Mateo?
Most San Mateo single-family homes land between a few hundred and a thousand dollars depending on size, stories, and siding. Free quotes within 24 hours.
Will soft washing damage my paint or stucco?
No — avoiding that damage is the point. Low pressure keeps water out of stucco and finish on the wood.
How often should I wash my house?
Every 1–2 years for most San Mateo homes; shaded, north-facing walls grow algae faster and may want annual attention.
Do you wash houses before painting or listing?
Constantly — a soft wash is standard prep before exterior paint, and pre-listing washes are one of our most common San Mateo calls.
Do you power wash houses in San Mateo?
We wash the outside of San Mateo homes every week, but not with a pressure washer aimed at siding. Low pressure and a detergent matched to the material remove the same algae and mildew a power wash would, without driving water behind stucco or lifting paint. If you searched for house power washing, this is the service.
Can you clean stucco without damaging it?
Yes. Stucco is porous, and high pressure forces water into the wall. We treat it at low pressure with enough dwell time to lift mildew out of the texture, then rinse. It comes out evenly clean, no wand marks.
