The Black Shark method

How your quote becomes a clean house

Concrete driveway before and after pressure washingFlat tile roof cleaning in progressSolar panel cleaning before and after
STEP 01

Photo in, quote out — 10 minutes

Text us a photo of the area (or just the address). You get a flat, no-surprises quote — usually within minutes, in English or Spanish. No walkthrough appointment, no salesman in your living room.

STEP 02

Pure water, exact pressure

Roof tiles get gentle flow. Concrete gets the full cut. Solar panels get deionized care. One method never fits every surface — that's why we bring the pressure and the restraint. Zero chemicals, every job.

STEP 03

Proof lands in your texts

Before/after photos sent the moment we finish — the same photos you're seeing on this page. Pay after the work, cash or Zelle. If it's not right, we make it right.

Questions we get a lot

How much does it cost?

Every home is different, so quotes are free and fast — usually within minutes from a photo. Our service-visit minimum is $150, and most customers bundle two or three services in one visit to get the most from it (roof + gutters + solar is a favorite). Roof cleaning starts at $550 — every quote is exact for your home before we start.

Do I need to move anything before you arrive?

Yes, please — clear furniture, planters, and anything sitting in the work area before we get there. If the area isn't ready when we arrive, we don't reschedule: we move what's in the way and a $25–50 moving fee is added (it genuinely adds time to the job). We can move it all back afterward for an extra charge, but we don't recommend it: surfaces need time to dry, and putting dirty furniture back on a freshly cleaned patio can stain it all over again. The better move — add outdoor furniture cleaning at $5 a piece while we're there, so everything goes back as clean as the ground under it. And a heads-up: cancelling a confirmed appointment carries a $50 fee — full policy in our service terms.

Do you use chemicals on my house?

No — that's the point. We clean with pure high-pressure water, dialing the pressure to each surface: strong on concrete, gentle on roof tiles and solar panels. Nothing harsh on your garden, your paint, or your pets' yard.

Will every stain come out?

Honest answer: most will, some won't — and we'll tell you which is which before we start. Dirt, grime, mold, mildew, and algae come off beautifully with pure water. But rust, oil, battery acid, irrigation stains, and efflorescence are chemically bonded to the surface — they'll lighten, but water alone can't erase them, and blasting harder only damages the surface. If a stain needs chemistry, we'll say so — and we'll even send you our free DIY treatment guide if you want to tackle it yourself. Full details in our service terms.

What's your guarantee?

We guarantee the process: every quoted surface cleaned completely and carefully at the maximum pressure that's safe for it. Before we pack up, we walk the whole job with you — anything we missed gets re-hit on the spot, free. That walkthrough is the moment: once we leave, the job is closed, and return visits are billed. What we don't do is re-run the full process on a surface that already got it — the result of a complete, correct wash is the result, and washing it twice doesn't change it. Re-cleans are a new job, no sooner than 30 days out.

Is cleaning solar panels actually worth it?

Yes — dirt and pollen buildup measurably cuts production, especially through our dry summers. Clean panels recover real output, and we can check your roof and gutters while we're up there.

Do you work on two-story roofs?

For safety we clean roofs and gutters on single-story homes only. House washing we take up to two stories.

How far do you really travel?

Our home turf is San Jose and the South Bay, but we cover the entire Bay Area — and regularly take jobs out to Sacramento, the Central Valley, Los Banos, and Monterey. If the job's right, the miles aren't a problem.
