Exterior cleaning services in San Jose
Every surface outside a home wants a different method. Here is how we approach each one, and what it usually involves on a San Jose property.
Pressure Washing in San Jose
Pressure washing is the right tool for hard, structurally sound flatwork — concrete driveways, walkways, steps and paver surfaces. It removes material by force, which is exactly what a slab needs and exactly what siding does not. On a San Jose property we set the pressure to the surface rather than running one setting across the whole job, and we use rotary surface cleaners on open flatwork so the finish is even instead of striped.
House Washing & Soft Washing in San Jose
Exterior house cleaning here covers stucco, vinyl siding, painted wood and fiber cement, and each behaves differently under water. Stucco is porous and absorbs; vinyl has overlapping panels that trap water forced behind them; painted wood splinters and loses finish. That is why house washing in San Jose is a soft wash — low pressure plus the right detergent, with dwell time doing the actual work on algae, mould and mildew.
Roof Cleaning & Organic Growth Removal in San Jose
Roof washing in San Jose is worth doing before the growth becomes structural rather than cosmetic. Lichen in particular anchors into the shingle surface and is far harder to remove once established. Everything we do on a roof is low pressure — no wand, no blasting, no walking on tile anywhere weight should not go.
Window Cleaning in San Jose
Window cleaning in San Jose covers interior and exterior glass, frames, sills, tracks and screens. Tracks and screens are the part most often skipped, and skipping them is why glass looks hazy again within a week. Irrigation overspray is the other common issue: sprinklers hitting ground-floor glass leave mineral deposits that ordinary glass cleaner will not remove and that need a specific hard-water treatment.
Gutter Cleaning in San Jose
A clogged gutter is not just an overflow problem. Packed wet debris is heavy enough to pull fasteners loose and sag the run, and standing water keeps the fascia and roof edge permanently damp. On San Jose properties, especially those under mature trees, twice a year is the baseline — once before the wet season and once after it.
Solar Panel Cleaning in San Jose
The best time for solar panel washing in San Jose is late summer through early autumn — after a full dry season of accumulation, and before shorter winter days when every bit of light counts. We clean with soft brushes and deionised or filtered water so the glass dries without spotting, and we clear debris from the array edge and adjacent roof valley at the same time.
Driveway Cleaning in San Jose
Driveway cleaning in San Jose deals with oil staining, tyre marks, algae in the shaded sections and general traffic film. We use rotary surface cleaners rather than a handheld wand, which is what produces an even finish instead of the striped, arc-patterned look a wand leaves. Oil and rust need targeted pre-treatment before the main clean rather than the same approach as everything else.
Concrete & Sidewalk Cleaning in San Jose
Walkways, sidewalks, entry steps, pool surrounds and garage aprons all fall under concrete cleaning. On San Jose properties we pre-treat organic growth so it is killed at the root, surface clean the field of the slab for even coverage, then detail edges, joints and steps by hand where a surface cleaner cannot reach.
Patio & Deck Cleaning in San Jose
If you are planning to stain or seal a deck in San Jose, clean first and let it dry fully — usually a couple of days. Sealing over a damp or dirty deck traps the problem underneath and causes hazing, which is a callback nobody wants.
Commercial Exterior Cleaning in San Jose
Commercial exterior cleaning in San Jose covers storefronts, office buildings, walkways, entryways, parking areas, dumpster pads and awnings. Most of it is better done outside business hours, so early morning, evening and weekend scheduling is normal — the goal is that customers see the result and never see the work.
What we commonly see on San Jose properties
San Jose covers an enormous area with very different housing depending on where you are — post-war ranch homes in Willow Glen and the Rose Garden, larger newer construction in Almaden and Evergreen, and dense infill closer to downtown. Practically, that means a quote here depends far more on the specific property than on the city. Stucco is the dominant siding material across most of San Jose, and concrete driveways and walkways are close to universal, which is why house washing and driveway cleaning are the two services we are asked for most often here.
Common exterior cleaning problems in San Jose
Most of what makes a San Jose exterior look tired is biological rather than dirt. Algae, mildew, moss and lichen grow where shade and moisture last longest, and they have root structure in whatever they are growing on — which is why rinsing removes the colour for a few weeks and then it comes back. Not every property has all of these — but most have two or three.
- Algae, mould and mildew on siding. Usually worst on north-facing elevations and anywhere under tree cover, where surfaces stay damp longest.
- Roof streaking, moss and lichen. Dark streaks on asphalt shingle are typically algae; moss and lichen establish in valleys and along shingle edges where debris holds water.
- Black staining on shaded concrete. Organic film on walkways and driveway edges. It is also slippery when wet, which makes shaded flatwork a safety issue as well as an appearance one.
- 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.
How we clean different exterior surfaces
The single biggest decision on any exterior job is how much force a surface can take. Here is how we match method to material.
| 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 San Jose homeowners choose Peninsula Exterior Care
We work in San Jose regularly rather than passing through. That means we walk the property with you first, use the method each surface actually needs, and tell you honestly when something — old oil, long-set hard water etching, efflorescence — will improve rather than disappear.
Peninsula Exterior Care did an awesome job with our exterior windows. Habib was super professional and courteous. He explained what he was gonna do and was done in time. They have a water softener system and the windows clean out squeaky clean.
We don't always get our windows cleaned, but when we do it will be Peninsula Exterior Care :)
Habid just finished soft washing outside of house and washing windows including outside porch and banisters. My house is a single story, 1915 CA craftsman's house. I hired him because he I had the option of a non pressurized wash. Because my house is old, I didn't want to use too much pressure. He is meticulous and provided a fair price for all the work he did. No damage at all to the stucco or wood from the washing. It turned out great! I see he does other soft and pressurized cleaning. I will most likely be hiring him again for my sidewalk and brick patios.
Exterior cleaning FAQs — San Jose
How much does pressure washing cost in San Jose?
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.
Is pressure washing safe for stucco?
High pressure is not. Stucco is porous, and pressure can force water into and behind the surface and open up hairline cracking. Stucco gets a soft wash: low pressure plus a detergent that breaks down algae and mildew chemically, with dwell time doing the work.
Should vinyl siding be pressure washed or soft washed?
Soft washed. Vinyl panels overlap, and water driven behind them at pressure does not drain or dry, which is how you end up with mould inside a wall cavity you cannot see. Low pressure and the right solution clean it more thoroughly anyway, because they kill organic growth at the root.
Can pressure washing remove black stains from concrete?
Usually yes, when the black is organic growth — which on shaded San Jose flatwork it typically is. We pre-treat so the growth is killed rather than knocked back, then surface clean. Mineral efflorescence is different: it can be reduced but it recurs, because the cause is moisture inside the slab.
Can you remove oil stains from a driveway?
Partly, and how much depends on age. Fresh oil usually comes out well. Oil that has been soaking into porous concrete for years typically lightens substantially rather than disappearing completely. We will tell you what to realistically expect before starting, not after.
How often should gutters be cleaned?
Twice a year for most San Jose 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 San Jose?
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.
