Pressure Washing Cost in Los Angeles

Driveway 400 sqft: $120–$220

A standard two-car driveway in LA is roughly 400–500 square feet of concrete or pavers. Pressure washing it runs $120–$220 — about $0.30–$0.55 per square foot, which is the typical LA range you'll see across direct local pros, Yelp listings, and the major platforms. The lower end is a once-a-year clean on a flat driveway with no significant staining. The higher end includes oil spot pretreatment with a degreaser, edge-of-driveway weed and moss removal, and a post-rinse with clean water rather than just shutting off the unit.

Surface matters more than people expect. Plain broom-finish concrete from the 1960s through the 1990s — most of the Valley, South LA, and the older flatlands — is the easiest surface to clean and sits at the lower end of the price band. Stamped or colored concrete from the 2000s onward is more delicate; pros use a wider fan tip and lower PSI to avoid stripping the color sealer, and that's slower work. Pavers are slowest of all because the joint sand has to be re-swept in afterward, which adds $30–$60 to the visit.

What pressure washing won't fix on a driveway: deep-set rust stains from a leaking car, oil that's been soaked in for years, or efflorescence (the white chalky bloom on some concrete). Pros will tell you on arrival whether those will lift or not — sometimes they do, sometimes they need a chemical pretreatment that's a separate $40–$80 add-on, sometimes they're permanent.

Walkway and patio: $80–$160

Front walkway, back patio, side-of-house concrete strip — all sit in the $80–$160 range for a standalone visit. The lower end is a single short walkway from sidewalk to front door, maybe 50–80 square feet. The higher end is a full back patio of 200+ square feet or a walkway with a lot of plant overhang where the pro is also blowing leaf debris and trimming back grasses to expose the edge of the concrete.

Most LA pros price walkway and patio bundled with a driveway clean at a discount — a driveway plus a walkway might run $160–$280 total rather than $200+ as separate visits. If you're booking, mention everything you want washed in the same visit; you'll save $30–$80 versus two separate bookings.

Exterior stucco siding: $240–$480

Soft-washing the exterior of a single-story stucco home in LA runs $240–$480. The wide range tracks both the size of the house and the staining situation. A 1500 sqft single-story in the Valley with normal dust and the occasional cobweb is $240–$320. The same home with significant marine-air staining (Mar Vista, Venice, Santa Monica, Playa del Rey, anywhere within a mile or two of the coast) runs $320–$480 because the pro is using a stucco-safe surfactant and a longer dwell time before rinsing.

Stucco is not actually pressure washed in the way concrete is — high pressure damages stucco. What's happening is closer to soft washing: a low-pressure detergent application followed by a low-pressure rinse, sometimes with a softening agent for hard water. Westside homes age faster on the stucco because chloride from marine air slowly degrades the surface, so the staining you're trying to remove is partly biological (mildew, algae) and partly mineral. Pros who work the Westside regularly carry a different chemistry mix than pros who mostly do inland Valley work.

Two-story stucco runs roughly 1.5x to 2x the single-story price ($380–$780 typical) because of ladder time and the slower, more careful rinse pattern needed at height. Get a same-visit gutter clean quote at the same time — you save the trip charge and the pro is already up on the ladder.

Wood deck: $160–$280

Wood decks need the gentlest treatment of any surface a pressure washer touches. The right approach is a fan tip at 1500–2000 PSI held 12+ inches off the wood, working with the grain. Done correctly, you get a clean deck without raised grain or fuzz; done with the wrong tip or pressure, you get a deck that will need full sanding and refinishing.

A typical 200–300 sqft wood deck in LA runs $160–$280 to wash. The lower end is a deck under five years old where the wash is mostly cosmetic. The higher end includes brightener application after the wash — a percarbonate or oxalic-acid based brightener that lifts the gray oxidation and prepares the wood to take stain or sealer well. If you're planning to refinish the deck within the next month, the brightener step is worth the extra $40–$80 because it's part of proper prep, not a cosmetic upsell.

What pressure washing won't fix on a deck: rotted boards, popped fasteners, or split boards. Those need replacement, not cleaning. A pro will point them out during the wash visit and you can decide whether to add deck repair as a separate scope or just wash and accept the cosmetic limits.

Fence: $120–$260

A standard backyard fence in LA — typically 80–150 linear feet of cedar, redwood, or pine — runs $120–$260 to wash. Pricing tracks fence height (6 ft is standard, 8 ft adds 20–30 percent) and access (fence with planter beds and AC units in front of it is slower than a clean fence with grass on both sides).

Like decks, fences need lower pressure than concrete. The pro is removing surface mildew, algae growth (especially on north-facing sections that don't get sun), and the layer of dust and fine debris that builds up on horizontal rail caps. After washing, the wood is significantly lighter — sometimes uncomfortably so — and most homeowners then book a stain or seal application within a few weeks. We can refer that out on the same platform if you want it.

LA-specific staining: hard water, jacaranda, marine air

Three types of staining are specific enough to LA that pros price them separately:

• Hard water mineral deposits ($30–$80 add-on): LA tap water runs 250–500 ppm hardness depending on neighborhood. Sprinkler overspray on stucco and irrigation drips on driveway edges leave white mineral haze that won't come off with plain water. Pros use a mild acid wash (oxalic or hydrochloric, depending on surface) to dissolve the deposits, then neutralize and rinse.
• Jacaranda blossom stains ($40–$80 add-on, May–June only): The purple flowers that drop across Hancock Park, Beverly Hills, and parts of South LA stain concrete a faint pink-purple when they sit and decompose. A surfactant pretreatment plus warm-water rinse handles it; cold-water-only rigs leave streaks.
• Marine air mildew ($60–$120 add-on, Westside only): Stucco within a few miles of the coast picks up black-streak mildew on the north and east-facing walls. Westside-specialized pros use a sodium-hypochlorite-based soft wash with thorough plant protection — neutralized before rinse, so landscaping isn't damaged.

Bundling: how to get the most out of a single visit

Pressure washing is one of the categories where bundling really moves the price. The pro's setup time — pulling up, unspooling hose, filling tanks, testing pressure — is the same whether they wash one surface or four. Most LA pros pass that efficiency back to the homeowner in a bundle quote.

A common Westside or Valley bundle: driveway plus walkway plus front-of-house stucco plus mailbox area. Standalone, those four scopes might quote at $120 + $80 + $240 + $40 = $480. As a single bundled visit, expect $380–$420 — about a 15 percent saving for combining. The same logic applies to a back-of-house bundle: deck plus fence plus patio plus exterior of detached garage. Mention everything you want washed at booking time; the pro can scope it all on arrival and quote accurately rather than upselling once they're already on site.

One thing not to bundle: pressure washing immediately before painting. The deck or stucco needs to dry fully — usually 48–72 hours in LA's dry climate, longer if the wood is dense — before primer or paint goes on. Schedule the wash at least three days before any paint visit.
