Moss, algae, and winter grime removed from the surfaces that take the worst of the Pacific Northwest weather.
There is no part of the country where pressure washing matters more than western Washington. Roughly seven months of rain and shade turn concrete green, put a black algae streak down the north side of every house, and grow moss thick enough in driveway expansion joints to lift the concrete. Most Renton homeowners stop noticing because it happens gradually — and then they see the clean strip where a planter was sitting and realize how far it had gone.
We've been pressure washing in Renton since 2004. Owner Jack Kapala walks the property, tells you which surfaces are worth doing and which aren't, and quotes each one as a separate line item. If your driveway needs it and your siding doesn't, he'll say so — the goal is a customer who calls us again next spring, not the biggest possible invoice this week.
Pressure is matched to the surface. Concrete gets high pressure. Siding, paint, and wood decking get low pressure with the work done chemically instead of by force. That distinction is the whole job — it's why a professional wash looks even and a rental-machine wash leaves wand marks, stripped paint, and furred wood grain.
Moss and algae are not dirt. They are living organisms that root into the pores of concrete and the grain of wood, and they grow specifically in the conditions Renton provides for most of the year: consistent moisture, mild temperatures, and shade. That's why a surface that's been blasted clean with water alone often looks green again within a few months — the pressure removed the visible growth but left the root structure behind.
Our approach treats the growth chemically first, then rinses at the pressure appropriate to the surface. That takes longer than blasting, and it lasts substantially longer. Neighborhoods under heavy Douglas fir and cedar cover — Fairwood, the Renton Highlands, the Cedar River corridor, and the shaded slopes above Kennydale — see the biggest difference, because needle drop keeps surfaces damp and feeds the growth all winter.
There's also a safety argument that isn't marketing. Wet moss on a concrete walkway or a set of front steps is genuinely slick, and it's the reason a fair number of our spring calls come from people who nearly went down on their own front path.
May through September is the working season. Surfaces are dry enough to treat properly, the growing season for moss has paused, and the result holds through the dry months and well into the next winter.
Before listing a property is the other high-value moment. A green driveway and streaked siding read as deferred maintenance in listing photos, and it is one of the cheapest pre-sale corrections available. If you're prepping a property, this pairs naturally with a move-out clean.
After construction or landscaping work — concrete dust, mortar splatter, and soil staining all come up far more easily within a few weeks than after a year of weathering.
Entryways, sidewalks, loading areas, and dumpster pads are what customers and tenants actually walk across. We handle recurring exterior washing for retail, offices, and multi-tenant properties across Renton, scheduled outside of business hours where access allows.
Certificates of Insurance naming your business or property management entity as additional insured are issued at no charge. If you also need interior janitorial, both scopes can run on a single monthly invoice — see commercial cleaning in Renton.

Pressure washing is quoted by surface and square footage, not by the hour. A standard two-car driveway, a patio, a deck, and a full siding wash are four different numbers. Jack looks at the surface type, the square footage, how much organic growth is on it, and access — then gives you a firm written figure. There's no charge for the estimate.
Not if the pressure is matched to the surface. Concrete driveways and walkways take high pressure. Siding, painted surfaces, and wood decking take much lower pressure with the cleaning done chemically rather than by force — that's the difference between a clean surface and one with the grain torn open or the paint stripped. Using driveway pressure on cedar siding is the single most common way DIY pressure washing goes wrong in this region.
Late spring through early fall. Moss and algae do their growing during our wet season, roughly October through April, so washing in May or June removes a full season of growth and leaves the surface clean through the dry months. Washing in the middle of winter is possible but the growth simply returns faster, so you get less value per dollar.
Most Renton properties want driveways and walkways done annually, and siding every two to three years. Anything under heavy evergreen cover — which is much of Fairwood, the Highlands, and the Cedar River corridor — moves to annual for everything, because needle drop and shade accelerate moss growth dramatically. North-facing surfaces always need it more often than south-facing ones.
Driveways, patios, decks, siding, and walkways. If you're unsure whether your surface is a good fit — painted concrete, pavers, composite decking, older stucco — call Jack and describe it. He'd rather tell you honestly that something isn't a good candidate than take the job and damage it.
Yes, an outdoor spigot and a standard exterior outlet. We bring the equipment and all cleaning solutions. If your spigot is inside a locked gate or the outlet is on a GFCI that trips, just mention it when you book and we'll plan around it.
A driveway is usually an hour or two. A driveway plus front walkway and patio is a half day. A full house siding wash is typically a full day depending on square footage and stories. Jack gives you a time estimate with the quote, and the crew sends the day-before text with the exact arrival time.
Yes. We use non-toxic products across the business, and it matters more outdoors than indoors — whatever you put on a driveway in Renton runs into a storm drain and, in much of the city, into the Cedar River or Lake Washington watershed. We choose products with that in mind.
