Frequently asked questions

Yes. In addition to standard pressure washing, we offer hot-water power washing for gas stations and properties with heavy grease, oil, grime, or built-up stains. Hot water breaks down oils that cold water simply can't.

We match the technique and pressure to the surface — using lower-pressure soft-wash methods on delicate materials like stucco and painted siding, and higher pressure only where it's appropriate, like concrete.

It depends on the size, surface, and condition of the area, plus whether hot water or soft washing is needed. We provide free, no-obligation quotes — call or text us with a few details and we'll get you a fast estimate.

Pressure washing uses high water pressure to blast dirt off hard surfaces like concrete. Soft washing uses low pressure plus specialized cleaning solutions to safely clean delicate surfaces — stucco, painted siding, and wood — without forcing water behind them or stripping the finish. We use whichever is right for the surface, and often both on a single property.

In most cases, yes. Fresh and moderate oil stains respond well to hot-water washing combined with a degreaser. Older stains that have soaked deep into the concrete may lighten significantly rather than disappear completely — we'll set clear expectations when we see the surface.

Not necessarily. As long as we have access to the areas being cleaned and an outdoor water spigot, many jobs can be completed whether or not you're present. We'll confirm access details when we schedule.

Any time of year works in our mild climate, but late spring through fall is popular for tackling the mildew and moss that accumulate over the wet winter. Many homeowners schedule an annual or twice-yearly wash to stay ahead of organic buildup.

Purified (deionized) water contains no minerals, so it lifts dirt and rinses away without leaving spots or residue — and it means no chemicals touch your panels. Combined with soft brushes, it's a scratch-safe way to clean delicate solar glass.

Yes. Dust, pollen, bird droppings, and grime block sunlight and reduce production. Regular cleaning helps your system perform closer to its rated output.

Most Bay Area systems benefit from cleaning once or twice a year, more often near trees, farms, or dusty areas, or after wildfire-season ash. We're happy to recommend a schedule based on your location and how quickly your panels soil.

Yes. Many manufacturers void warranties if abrasive pads or harsh chemicals are used. We use only soft, panel-safe brushes and 100% purified water — no detergents and nothing abrasive — so the glass and your warranty stay protected.

Yes. We clean residential rooftop systems, ground-mount arrays, and larger commercial or multi-panel installations. Tell us your system size and location when you request a quote and we'll scope it accordingly.

It varies with how dirty the panels are and your local conditions, but soiling commonly trims production by a noticeable margin — and that loss compounds over time. Regular cleaning helps your system perform closer to its rated output and shortens its payback period.

We filter water through a 3-stage purification system to remove all minerals, then clean and rinse with that 100% purified water. The glass dries spot-free and streak-free naturally — no detergents needed.

Yes, we clean interior and exterior glass, and can wipe down screens, sills, and tracks. Let us know what you need when you request a quote.

Yes. Our water-fed pole system lets us safely clean upper-story and hard-to-reach windows from the ground — no ladders against the house and no risky climbing.

Most homeowners clean their windows once or twice a year, while storefronts and offices often schedule monthly or quarterly service to keep a sharp first impression. Homes near busy roads, construction, or heavy tree cover may want more frequent cleaning.

Often, yes. Light to moderate mineral spotting from sprinklers and hard water typically comes off with our process. Severe, long-standing etching that has set into the glass is harder to fully reverse — we'll let you know what's realistic after we look.

Yes. We clean storefronts, offices, and professional centers, and can set up recurring service so your glass always looks its best for customers and staff.

Often, yes. Graying is usually a weathered surface layer. We clean and brighten the wood to bring back its natural tone and prepare it for sealing or staining.

Our focus is professional cleaning and restoration prep. Tell us your goal when you request a quote and we'll advise on the best approach for your wood.

Not when it's done correctly. High pressure alone can gouge and splinter softwoods, so we use lower-pressure, surface-safe methods paired with the right cleaners to lift dirt and the gray layer without harming the boards.

Wood needs to dry thoroughly before it will accept stain or sealer — typically a couple of dry days, depending on weather and how saturated the wood got. We'll give you a recommended window for your project so the finish bonds properly.

Yes. Composite and capped-composite decks can collect mildew, algae, and grime in their texture. We clean them with gentle, manufacturer-appropriate methods that lift the buildup without dulling or damaging the surface.

Yes. Organic growth like mildew, algae, and moss is one of the most common reasons wood looks dingy. Our cleaning solutions break it down at the root rather than just rinsing the surface, so the wood comes back cleaner and stays clear longer.

Most Bay Area homes do well with cleaning once or twice a year — typically in late fall after the leaves drop, and again in spring. Homes surrounded by trees often need it more often.

Yes. We clear the gutter troughs and flush the downspouts to make sure water actually drains — a clogged downspout is a common cause of overflow even when the gutters look clean from the ground.

Yes — we bag and remove the debris we pull from your gutters, so you're not left with a pile to deal with afterward.

Clogged gutters overflow and send rainwater down your siding and foundation instead of away from the house. Over time that leads to fascia rot, leaks, stained walls, and pooling around the foundation — all far more costly to fix than a routine cleaning that prevents them.

While we clean, we look for common problem signs — sagging sections, loose fasteners, separated seams, and evidence of overflow — and we'll let you know what we find so you can address small issues before they cause water damage.
