What we wash
We pressure wash driveways, walkways, patios, pavers, decks, porches, fences and siding, and we clean windows. Concrete can take higher pressure. Pavers take less, and wood and siding get a low-pressure wash, because the goal is to lift moss and grime without etching, gouging or forcing water where it doesn’t belong.

| Surface | What Tacoma weather does to it | Pressure | Watch out for |
|---|---|---|---|
Driveways & walkwaysPoured concrete | Green algae film, moss in the control joints, fir-needle and leaf stains, tire marks. | Higher | Aging or soft concrete can show wand marks. Oil stains usually lighten rather than vanish. |
Patios, pavers & brickPavers, brick, stone | Moss and weeds in the joints, black algae in shade, slick steps. | Medium | Joint sand washes out and may need topping up. Older mortar needs a gentler touch. |
Decks & porchesWood and composite | Gray weathering, green film on shaded boards, slippery stairs. | Low | Too much pressure raises the grain and gouges boards. Wood must dry before any stain or sealer. |
FencesCedar and painted wood | Green mildew on the north face, gray boards, moss at the base. | Low | Old, soft pickets can splinter. Rotten boards need replacing, not washing. |
Siding & trimLap, shingle, painted | Green streaks on the shady side, mildew under eaves, overflow stains below gutters. | Low rinse | High pressure forces water behind lap siding and lifts loose paint. |
WindowsGlass and frames | Film, water spots and pollen after a long rainy season. | Window cleaning | Book after the siding wash so rinse water doesn’t spot clean glass. |

Pressure vs. soft washing
A pressure washer strong enough to strip moss off a driveway will also fuzz cedar, gouge a deck board or drive water behind lap siding. So the pressure, the tip and the distance change with the surface. On siding and painted wood, a low-pressure rinse, often called soft washing, does the cleaning without the damage.
High pressure tears the soft grain out of cedar and fir, leaving a rough surface that grays and holds moisture faster.
Spraying up under lap siding pushes water into the wall, the one place a Tacoma house least needs more.
Too close a tip leaves wand marks on concrete and strips the joint sand out of pavers.
The rule we work by: pressure matched to each surface. If a stain won’t lift at a safe pressure, we’ll tell you rather than damage the surface chasing it.



Moss & algae
Tacoma gets measurable rain on about 155 days a year, and roughly three-quarters of its 40.81 inches falls from October to March. Concrete, pavers and wood that sit in shade under firs or on the north side of a house barely dry out all winter, so moss and algae move in. Washing lifts the growth and the slippery film; keeping it away means fixing what keeps the surface wet.
A green film on concrete steps and walkways is algae, and it’s a slip hazard.
It holds water against the slab and lifts paver sand.
Often gutter overflow. Fix the gutter or the green comes right back.

Tacoma stormwater rules
Tacoma’s storm drains flow to creeks, lakes, wetlands and Puget Sound. The City of Tacoma prohibits pressure washing water that carries soaps, chemicals or soil from entering storm drains. Its guidance allows only plain, cold rinse water from building walls and sidewalks to reach a drain, with the inlet protected.
“If it hits the ground, it hits the Sound.” City of Tacoma
Wash water with cleaners, detergents or dirt can’t enter storm drains. It harms fish and pollutes the Sound.
City of TacomaPlain cold water with no soap, oil or paint, and inlet protection on any drain the work could reach.
Tacoma discharge tableThe City’s table doesn’t allow parking-lot wash water into the storm system. It goes to the wastewater system or gets collected.
Tacoma discharge tableCommercial, industrial or multi-story residential buildings of that era may have PCBs in caulk and paint. Don’t pressure wash until testing is done.
WA Department of EcologyHiring anyone to pressure wash? Ask three questions.
Are you licensed in Washington? Look the company up on L&I Verify.
Tacoma averages under 1.6 inches of rain a month from June through September, and July averages just 0.55 inches. That’s the easiest window, because surfaces dry and stay clean. Spring is the other busy time, when winter moss has made steps slick. Book a dry week and clean the gutters first so overflow doesn’t streak the fresh work.
Refinishing a deck or fence? Wash it first, then give the wood dry weather before any stain or sealer goes on.
Selling or hosting? A clean walkway, driveway and siding is an easy curb-appeal fix. Ask about bundling with gutter cleaning.

How it works
Pictures of each surface, plus the gutters above them, are often enough to price.
Each surface listed, so you know exactly what’s getting washed.
Concrete, pavers, wood and siding each get the pressure they can take.
We go over the work with you, including any stain that wouldn’t lift safely.
We don’t publish flat pressure washing prices, because a front walk and a moss-covered deck with two sides of siding are very different jobs. Pressure washing cost in Tacoma comes down to square footage, the surface, how much growth there is, access and how the wash water has to be handled. The estimator gives you a range from your address.
Price my pressure washing onlineA front walk and steps is a short job. A long driveway, a wraparound deck and two sides of siding add up by the foot.
Concrete washes faster than pavers, and wood and siding take more care and a lower-pressure approach.
A light film lifts quickly. Thick moss in every joint and years of algae on a shaded deck take longer.
Steps, slopes, tight side yards and second-story siding take more setup than open, ground-level concrete.
Where drains sit and what the surface is decide how rinse water has to be protected or collected.
Gutters first, then the surfaces below, on one visit. Ask about bundle pricing when you request your estimate.
A good wash makes a big visible difference, but it isn’t a restoration or a repair. These are the honest limits, and we’ll point them out on your surfaces before the work starts.
Washing usually lightens old oil and rust marks on concrete. Set into the surface, they rarely disappear completely.
Washing removes grime and green film. Restoring the color of sun-grayed boards takes refinishing after the wood dries.
Clean concrete under firs or on a north side will grow green again. Repeat cleanings and drier ground slow it.
A driveway wash doesn’t touch the roof. Roof moss is its own service, with its own method: roof cleaning and moss removal in Tacoma.
Our Washington office is at 3818 S 66th St in South Tacoma, so crews reach most of the city in a short drive. Shady, tree-lined streets in the North End and West End tend to grow more moss on walks and decks, while South End ranches often need driveways and long runs of siding washed.

Questions & answers
Cost, safety, timing and the City’s wash-water rules. Still unsure? Send a photo of the surface and we’ll tell you what it needs.
Call (425) 828-3000It depends on the square footage, the surface, how much moss and staining there is, and access like steps, slopes or second-story siding. We don’t publish flat prices. Use our online estimator for a range, or send photos for a free written estimate, usually within 24 hours.
Yes, at the right pressure. Too much pressure can force water behind lap siding, strip paint and gouge or fuzz wood, so siding and decks get a low-pressure wash and concrete gets more. That’s what we mean by pressure matched to the surface.
Not if it carries soap, chemicals or soil. The City of Tacoma prohibits that. City guidance allows only plain cold water from washing building walls and sidewalks to reach storm drains, with inlet protection in place. Other wash water has to be collected.
On a dry stretch, so surfaces can dry afterward. Tacoma averages under 1.6 inches of rain a month from June through September. Spring is the other popular time, when winter moss has made steps and walkways slick. Clean the gutters first so overflow doesn’t streak a fresh surface.
On shaded concrete and wood, eventually yes. Washing removes the growth, but surfaces that stay damp under firs and on north sides regrow. Fixing gutter overflow that keeps a spot wet slows it down. Plan on repeat cleanings.
Roofs are a separate service. Moss on shingles is handled as roof cleaning and moss removal, then the gutters below are flushed. See our Tacoma roof moss removal page for how that works.
Yes. Window cleaning is part of our exterior cleaning work, and it’s easy to book with a pressure washing visit. Ask for both when you request your estimate.
It can. For commercial, industrial or multi-story residential buildings built or renovated between 1950 and 1980, the City of Tacoma says not to pressure wash exteriors or nearby sidewalks until PCB testing is complete, and no wash water may reach storm drains.
