Exterior cleaning services in Millbrae
Every surface outside a home wants a different method. Here is how we approach each one, and what it usually involves on a Millbrae property.
Pressure Washing in Millbrae
Not everything outside a house should be pressure washed, and knowing where the line falls is most of the job. In Millbrae we use genuine pressure on driveways, walkways, patios and other hard flatwork, and switch to low-pressure soft washing the moment we move onto siding, stucco, painted wood or a roof. Same visit, two different methods.
House Washing & Soft Washing in Millbrae
Most of what makes a Millbrae house look tired is organic: algae, mildew and mould growing where shade and moisture sit longest, usually north-facing walls and anything under tree cover. Soft washing removes it properly because the solution kills the growth rather than knocking the top layer off, which is why results last a year or more instead of returning within weeks.
Roof Cleaning & Organic Growth Removal in Millbrae
Roof cleaning in Millbrae is about organic growth, not dirt. Dark streaking on asphalt shingle is typically algae feeding on the limestone filler in the shingle, and moss establishes in valleys and along shingle edges where debris holds moisture. We use low-pressure soft washing with a roof-safe solution. Pressure is never appropriate on a roof: it strips the protective granules off asphalt shingle and cracks tile, and it is usually what voids a manufacturer warranty.
Window Cleaning in Millbrae
Exterior window cleaning here deals with more than dust. Spring pollen bonds into a film, coastal and bay air leaves its own deposits, and hard water from irrigation builds mineral spotting season after season. We clean glass, frames, sills, tracks and screens, and we will tell you honestly when long-term etching will improve substantially rather than disappear.
Gutter Cleaning in Millbrae
Roof and gutter cleaning go together on most Millbrae homes, because the debris in the gutter came off the roof and the algae streaking on the siding is often runoff from the roof above. Doing both in one visit costs less than two mobilisations and gets a better result than either on its own.
Solar Panel Cleaning in Millbrae
Solar panel cleaning matters in Millbrae because of how long the dry season runs. From roughly May to October there is little rain to rinse anything off, so dust, pollen and airborne particulate accumulate uninterrupted for months. We use soft brushes and filtered water — nothing abrasive, and nothing that leaves mineral spotting on the glass as it dries.
Driveway Cleaning in Millbrae
Concrete and pavers are not the same job. Concrete takes real pressure; pavers have joint sand holding the surface together and lose it under too much force, which loosens the surface and opens the gaps to weeds. Paver driveways in Millbrae get controlled pressure and, where it is worth doing, fresh joint sand afterward.
Concrete & Sidewalk Cleaning in Millbrae
The white chalky bloom that appears on Millbrae concrete is efflorescence — mineral salts moving through the slab — and it is worth being straight about: it can be reduced but it recurs, because the cause is moisture inside the concrete rather than on it. Organic staining, by contrast, comes off properly and stays off for a season or more.
Patio & Deck Cleaning in Millbrae
Patio and deck cleaning in Millbrae covers wood, composite, paver and concrete, and each needs a different setting. Wood splinters and loses stain under pressure, composite has a textured surface that holds mildew and a manufacturer pressure ceiling, and pavers lose joint sand. Getting this wrong turns a cleaning job into a refinishing job.
Commercial Exterior Cleaning in Millbrae
For Millbrae commercial property, a recurring schedule usually costs less per visit than letting buildup accumulate for a year and then reversing it. Monthly or quarterly walkway and entry cleaning keeps a property consistently presentable, and we can quote by building or as a property-wide scope for HOAs and multi-unit sites.
What we commonly see on Millbrae properties
Proximity to the airport and the bay means more airborne particulate settling on glass and siding. Window cleaning cycles here are often shorter than elsewhere on the Peninsula, and north-facing walls hold organic growth through the damp months.
Common exterior cleaning problems in Millbrae
The common exterior problems on Millbrae properties fall into two groups: organic growth, and staining. Organic growth is alive and needs killing rather than blasting. Staining — oil, rust, tyre marks, mineral deposits — needs the right pre-treatment for the specific stain rather than more pressure. Not every property has all of these — but most have two or three.
- Tree-related buildup. Sap, leaf litter, seed pods and needles feeding growth on roofs, in gutters and across hardscape.
- Oil and tyre staining on driveways. Oil soaks into porous concrete rather than sitting on it, so it needs a degreaser and dwell time, not just pressure.
- Spider webs, nesting and entry grime. Eaves, porch ceilings, light fixtures and entryways — the details people see from two feet away.
- Hard water spotting on glass. Irrigation overspray leaves mineral deposits on ground-floor windows that ordinary glass cleaner will not remove.
- Traffic film and general dulling. Airborne dust and pollen that builds through the dry season and flattens the colour of a whole elevation.
- Algae, mould and mildew on siding. Usually worst on north-facing elevations and anywhere under tree cover, where surfaces stay damp longest.
How we clean different exterior surfaces
Pressure washing and soft washing are different tools for different materials. This is the short version of which gets used where.
| Surface | Method we use |
|---|---|
| Stucco | Porous and absorbent. Soft wash only — pressure can drive water behind the surface and open hairline cracking. |
| Vinyl siding | Low-pressure soft wash, worked top-down. Panels overlap, and water forced behind them does not drain or dry well. |
| Painted & wood siding | The gentlest setting we use. Pressure furs the grain and lifts paint unevenly. |
| Fiber cement | Tolerates more than wood but still gets a soft wash rather than pressure. |
| Asphalt shingle roof | Low-pressure soft wash. Pressure strips the protective granules and typically voids the manufacturer warranty. |
| Concrete & clay tile roof | Low pressure, deliberate foot placement on the structural high points of the tile profile. |
| Concrete flatwork | Genuine pressure with a rotary surface cleaner for an even finish, plus pre-treatment on organic growth. |
| Pavers | Controlled pressure to protect joint sand, with fresh sand afterward where it is worth doing. |
| Wood & composite decking | Low pressure with the grain. Composite has a manufacturer pressure ceiling worth respecting. |
| Glass, screens & solar | No pressure. Soft brushes and filtered water so the glass dries without mineral spotting. |

Why Millbrae homeowners choose Peninsula Exterior Care
Peninsula Exterior Care is professional and based in Atherton, so the person quoting your Millbrae job is the person doing it. We would rather set a realistic expectation up front than surprise you at the end.
I hired Peninsula Exterior Care to wash the roof and the entire exterior of my house in San Francisco, including all the walls, and I couldn't be happier with the results. Habib was professional, punctual, and paid close attention to every detail. The roof looks clean, the exterior walls look almost new, and the whole house has a fresh, well-maintained appearance.
If you're looking for house washing, roof cleaning, or exterior house cleaning in San Francisco, I highly recommend Peninsula Exterior Care. Habib explained the process, worked carefully, and left everything spotless. The service was excellent from start to finish, and the pricing was fair. I will definitely use Peninsula Exterior Care again and recommend Habib to anyone who wants high-quality exterior cleaning.
Habib did a great job on our deck roof ! He came on time, helped us move planters/ chairs etc out of the way and did a great job.
He was courteous, patient, thorough and respectful of our things / property . And he is reasonably priced too !
It was a pleasure to work with Habib. We will surely use his services for all our external washing needs !
Exterior cleaning FAQs — Millbrae
How often should gutters be cleaned?
Twice a year for most Millbrae properties — once before the wet season and once after. Homes under mature trees often need a third check mid-season. If you only do it once, do it in autumn, because that is the appointment that prevents damage rather than cleaning up after it.
Can you clean solar panels without damaging them?
Yes, with the right method. Panel glass scratches permanently, so nothing abrasive and no harsh chemicals go near it. We use soft brushes and filtered or deionised water, which also means the glass dries without leaving mineral spotting.
Do you clean second-storey homes?
Yes. Two and three-storey elevations, upper windows, skylights and roof work are normal parts of the job, and we bring the access equipment for it rather than skipping what is hard to reach.
Do you provide commercial pressure washing in Millbrae?
Yes — storefronts, offices, walkways, entryways, parking areas and building exteriors, for property managers, retail, restaurants and HOA common areas. Most commercial work is scheduled outside business hours.
Do you remove algae, moss and mildew?
That is the majority of what we do. All three are living organic growth, which is why we soft wash with a solution and dwell time rather than relying on pressure. Killing it at the root is the difference between results that last a year and results that last a month.
How soon can you get out to Millbrae?
Usually within a few days of booking. Autumn gutter season and spring are our busiest stretches, so book earlier in those windows if you need a specific week.
Do I need to be home during the work?
Not usually, as long as we have access to the areas being cleaned and an outdoor water spigot. Plenty of jobs happen while the homeowner is at work.
Is soft washing safe for my landscaping?
Yes. Plants near the work area are pre-wet before we start and rinsed thoroughly afterward, and anything particularly sensitive gets covered. Tell us about it when we walk the property.
How much does pressure washing cost in Millbrae?
It depends on the property rather than the city — square footage, number of storeys, the surfaces involved, how long it has been since the last clean, and access. We do not price by city, and we do not quote a range sight-unseen. Send a few photos or book a walkthrough and you will get a real number, usually the same day.

Old oil in concrete, long-set hard water etching and efflorescence all improve rather than disappear — any company promising complete removal is overpromising.
