Deck & Fence Washing in Duvall
Deck & Fence Washing in Duvall, WA
Duvall climbs from the river up a wooded hillside, and the housing ages as it goes: older homes under big trees near Old Town Duvall and Cherry Valley, newer plats up around Big Rock. The older half mostly needs a finish protected. The newer half mostly needs growth kept off. Both are wash jobs, just not the same wash.
Keeping the finish? The wash stays gentle and the coating stays put. Replacing it? The prep wash goes stronger and ends with a brightener, so the new coat grips clean wood.
The method holds either way: chemistry for cedar, pressure-treated wood, composite, or vinyl, soft-brush agitation where buildup calls for it, and no pressure washer anywhere in the process. The fence is quoted alongside the deck and cleaned the same day.

Duvall questions
- How do I know which wash my deck needs?
- Look at the finish. If it is intact and staying, the gentle wash preserves it. If it is sound but due for a new coat, the prep wash readies the surface, and a degraded finish will release along the way on purpose. If it has failed, or you are going dark to light, that is wood restoration, its own service.
- Our fence is green top to bottom. Does heavy growth change the price?
- It is one of the factors. The degree of growth and buildup figures into the quote alongside the size of the fence itself. Heavy green changes the effort, not the method.

Why it matters
The problem this solves.
A green deck is a slip hazard every time it is wet, which around here is most of the year. Your fence is fighting the same growth vertically: it darkens the boards, holds moisture against the wood, and breaks down stain and paint years early. Left long enough, a wash becomes a refinish.
How we do it
Our approach.
Two questions decide the wash before we quote: how old is the finish, and are you keeping it or prepping a recoat? Then the chemistry is matched to the material, because cedar, hardwood, composite, and vinyl each behave differently. The solution does the work, not pressure, and the deck and the fence come clean in the same visit.
- Material and coating check before chemistry
- Plantings pre-wet, runoff controlled
- Fixtures and furniture covered
- Soft-brush agitation, never forced pressure
- Low-pressure rinse on soft woods
- High pressure never touches vinyl
- Walk-through flags loose boards, fasteners, rot
Materials
Every material gets its own wash.
Cedar, hardwood, composite, and vinyl do not take the same wash. The method follows the material, and the first thing we do on site is confirm what the boards are and what finish is on them.
Cedar and Soft Woods
Pressure furs and splinters soft grain, so cedar gets chemistry and a low-pressure rinse instead. The dark streaks around knots and fasteners are tannin, and the oxalic brightener is what lifts them.
Oxalic Acid BrightenerPressure-Treated Wood
The workhorse of Eastside decks and fences, and it still gets the solution-first wash: the chemistry kills the growth, the rinse carries it off, and the surface of the boards stays put.
Hardwood Decking
Dense boards that weather to varied tones. We clean to the wood's actual color, say up front what a wash will and will not even out, and the brightener rebalances the surface before any new coat.
Wood RestorationComposite Decking
Algae grows on composite fine, and shaded composite can be slick within six months. There is no recoat to protect it, so the annual clean is its whole maintenance plan. Our wash will not etch or fuzz the texture.
Vinyl Fencing
High pressure never touches vinyl. The chemistry lifts the green film and a gentle rinse carries it away, so the panels come clean without pressure scarring.
Painted and Stained Wood
An intact finish gets the Maintenance Wash, which cleans without attacking the coating. A degraded finish will release under the prep wash, by design, because at that point the honest next step is a recoat, and a failed one is a job for wood restoration.
Wood Restoration
Cleaning or restoration?
Know which one your wood needs.
Washing maintains a finish. Restoration replaces one. They are different processes, and quoting the right one first saves you from paying for both.
| Maintenance Wash | Stain & Paint Prep Wash | Wood Restoration | |
|---|---|---|---|
| What it is | The gentlest material-matched clean | Stronger wash, extended dwell, agitation, brightener | A multi-step chemical process: strip, neutralize, rebalance |
| Right when | The finish is intact and you are keeping it | The finish is sound but due for a new coat | The finish has failed, the wood has grayed, or you are going dark to light |
| What happens to the finish | Preserved | A degraded finish releases, by design | Removed completely, old stain or paint stripped off |
| The wood afterward | Clean, safe underfoot, finish protected | Open and pH-rebalanced so the new coat bonds | Healthy bare wood, ready to take even a light-bodied stain evenly |
Going from dark to light, or the finish already failed?
That is restoration, not cleaning. Old stain or paint comes off completely, the wood's pH is restored, and the surface is left ready for a new finish to take evenly. It is its own service with its own page.
Wood Restoration & Paint PrepAdd-ons
Add it while we're there.
The crew and equipment are already on site, so these attach to your visit.
Oxalic Acid Brightener
Rebalances wood pH, lifts tannin darkening, and restores natural color to cedar, pine, and hardwood. It brightens, it doesn't seal.

Railings
Railings, balusters, and posts, priced apart from the deck surface. Ask up front so the estimate covers the whole deck.
Deck Glass
Deck and balcony glass panels cleaned on both sides, so the view matches the freshly cleaned boards.

Wood Restoration
When the finish is past cleaning: a multi-step chemical process that strips it, restores the wood's pH, and leaves the surface ready to take even a light-bodied stain evenly.

Why WindowWorks
Who shows up matters.
Anyone can rent a pressure washer. After 20+ years on Eastside exteriors, and a 4.9 rating across 300+ reviews, we can tell you the real difference is the person holding the wand: what they know, how they were trained, and whether the company behind them takes care of them. We take care of our techs, so they take care of your property.
Background-checked
Every technician is background-checked before they ever step onto a customer's property.
Certified, skill by skill

Paid like professionals
A living wage, healthcare, and dental. People who are treated well do careful work, and they stay, so you see the same faces.
Licensed, bonded, and insured
With OSHA-aligned safety training for the at-height work. If someone is on your roof, they are trained and covered for exactly that.
Method matched to the surface
Soft wash where pressure would damage, hot water where cold cannot lift, the right chemistry for the stain. The method follows the surface, not the other way around.
Documented before and after
Every job is photographed before and after, so you can see exactly what changed and keep it on file.
Common questions
Good to know.
Is this the same as stripping or refinishing?
No. Cleaning improves safety and appearance and preps the surface, but it doesn't strip stain, sand weathered wood, or fix failing paint; if your deck or fence needs more, we'll say so.
Why clean before a re-stain or repaint?
Coatings bond to clean wood, not to what's growing on it, so stain or paint over grime fails early and you pay twice. A thorough prep wash is what makes the new coat last.
Does composite still need a yearly clean?
Yes, for safety more than looks: algae grows on composite fine, and shaded composite can be slick within six months. Composite never gets a protective recoat, so the annual clean is its whole maintenance plan, and our method avoids etching or fuzzing the texture.
Will soft washing damage cedar or vinyl?
No, the method is matched to the material. Soft woods get a low-pressure rinse, high pressure stays off vinyl entirely, and the solution does the work instead of pressure.
Will everything look brand new afterward?
We set expectations by material first: degraded stain can look uneven once the grime is off, failing paint may release, aged cedar keeps some UV gray, and weathered hardwood can vary in tone. When that happens, the surface is ready for a recoat, and we'll say so.
How does pricing work when you do both?
Each is its own line on one estimate: the deck by material and area with railings priced apart, the fence by material, length, and height. One visit, one crew, one setup.
