Power Washing in Centralia

Centralia sits at the southern edge of our Puget Sound service area, off I-5 about 90 minutes south of Seattle, and we usually schedule Lewis County jobs on days we're already working Chehalis or Olympia to keep travel costs off your invoice. Most Centralia jobs get booked within 1-2 weeks of the call, and access is simple since most driveways and yards here have room for the truck and hose reels without street parking hassle. Call (206) 591-1096 and Vladislav will give you a real window, not a vague 'sometime next month.'

A standard driveway and walkway runs $150-$350, siding wash-downs run $300-$500, and a roof-and-deck combo lands around $250-$450, all depending on square footage and how much moss, oil, or mildew buildup there is to strip off first. Bundling siding, driveway, and a fence into one visit usually knocks 10-15% off the combined price since setup time only happens once. We quote a flat number after seeing the property, not a phone estimate that changes once the crew shows up. Call (206) 591-1096 for a free on-site walk-through and a written price before anything gets scheduled.

Straight exterior washing doesn't need a City of Centralia permit — it's routine maintenance, not construction. If the visit is really prep work ahead of re-siding, trim replacement, or a structural repair, that project itself would need sign-off through Lewis County Community Development, and we handle that paperwork as part of the larger job, not the wash itself. A few of the newer developments near Fords Prairie have HOA rules about driveway and siding upkeep, and we're happy to send photos afterward if your HOA wants proof of the work. WA Licensed Contractor, so anything that crosses into repair work is covered under the same license.

Not at the settings we run — Hardie fiber-cement and cedar both get a soft-wash approach under 500 PSI with a diluted sodium hypochlorite mix, never a turbo nozzle straight at the surface. Cedar decking gets an oxalic acid wood brightener pass afterward instead of just higher pressure, which is what actually removes the gray without gouging the grain. A rotary surface cleaner keeps pressure even across flat Hardie panels so you don't get the striped 'zebra' marks that come from a wand held too close in one spot. That's the difference between a wash that helps a repaint stick and one that voids the paint warranty.

Roofs and decks in this valley usually hold a clean look for 12-18 months before moss spores start showing again, faster on deep-shade lots near Fort Borst Park than on open, sun-exposed lots. Zinc control strips at the roof ridge stretch that out closer to 2-3 years by killing spores as rain washes over them. Siding and concrete hold up longer, typically 2-3 years, since they don't hold moisture the way a shaded roofline does. We don't warranty against moss returning entirely — that's a climate reality here — but workmanship on every wash is guaranteed, and we'll tell you honestly if a spot needs re-treating within the first season.

Yes — Chehalis, Napavine, and the Olympia area all get covered on the same trip schedule as Centralia, so groups of jobs in that corridor get booked together during the week. Typical scheduling window runs 1-3 weeks out depending on season, with spring being the busiest stretch after a wet winter builds up moss and algae. Vladislav quotes every job in person himself — the same owner who's completed 100+ remodel and exterior projects since 2023 handles the walk-through, not a sales rep or a subcontracted crew showing up cold. Call (206) 591-1096 to get on the schedule or ask about combining a wash with an upcoming remodel or repaint.
