GreenTree washes the gray, moss, and algae off Portland fences, restoring wood, vinyl, and composite to a clean, bright finish across Multnomah County. Every job is backed by a written price-lock quote, $2M insurance, and our Triple Protection Guarantee.
Most fence cleaning in Portland runs $250 to $750, depending on the length and material of the fence and whether you add brightening or sealing. A standard backyard wood fence runs about $300 to $500. GreenTree uses a soft-wash approach and locks the price in writing first.
Portland gets about 43 inches of rain across roughly 155 wet days a year. As a result, fences stay damp, wood grays, and a green film of algae and moss spreads across every panel, especially on the shaded north side.
A fence in the Portland metro is exposed on every face, all year. The wet season feeds moss and algae in the grain, while summer UV bleaches the wood gray. Vinyl and composite fences do not rot, but they still grow the same green and black film that makes a yard look neglected. Over time, the growth holds moisture against wood and speeds up the rot.
Cleaning a fence is the cheapest way to protect it and to lift the whole look of a property. For example, a clean, bright fence makes a Portland backyard or rental look cared for. By contrast, a gray, mossy one drags down the entire yard. A professional wash clears the growth at the root and, on wood, prepares the surface for a sealer that slows it coming back.
A proper fence wash lifts more than surface dirt. Our crew clears green algae and black mildew, plus the gray weathered layer on wood. Beyond that, it lifts the moss behind the boards and the cobwebs that collect along the rails. On vinyl, we cut the chalky film and road grime. The result is an even, bright finish on every panel rather than a streaky, half-clean look.
From the front of the property to the back, we handle every surface that needs it.
Soft-washed to lift gray, moss, and algae without gouging the grain, then optionally brightened and sealed.
The chalky film and green growth come off with a low-pressure wash and the right cleaner, restoring the white.
Trex-style panels cleaned of algae and grime without the harsh scrubbing that can damage the surface.
Rust film, moss, and grime cleared from the mesh and posts for a clean, uniform look.
The detail areas, hand-cleaned so the gates and posts match the rest of the fence line.
Block walls and privacy screens cleaned alongside the fence to finish the whole boundary.
A four-step process that matches the method to the surface, so it comes clean without damage.
First, we walk the fence line with you and identify the material, since wood, vinyl, and composite each need a different touch. We note the worst of the moss and any loose or damaged boards.
Next, we apply a cleaning solution that kills moss, algae, and mildew at the root. Pre-treating lifts what a plain rinse leaves behind and keeps the green from coming back as fast.
We then soft-wash the fence with low pressure rather than blasting it. As a result, the growth and gray come off evenly without gouging wood, etching vinyl, or driving water behind the boards.
Finally, on wood we can apply a brightener to even out the tone, or a sealer that repels water and slows the moss. Both extend how long the clean finish lasts in {city}’s climate.
fence cleaning in Portland typically runs $250 to $750. A standard backyard wood fence runs about $300 to $500, vinyl runs a bit less, and adding sealing on wood costs $1.50 to $3.00 per linear foot. The exact price depends on length and material, and GreenTree quotes it all in writing first.
The price of fence cleaning in Portland depends on the length of the fence, the material, and whether you add brightening or sealing on wood. A short vinyl run costs less than a long cedar fence that needs sealing. Every figure is locked in writing before we start.
| Fence Cleaning service | Typical Portland price | Notes |
|---|---|---|
| Standard backyard wood fence | $300 to $500 | Soft wash, moss and gray removal |
| Long or double-sided wood fence | $450 to $750 | Both faces cleaned, more linear feet |
| Vinyl or PVC fence | $250 to $450 | Low-pressure wash, film and green removal |
| Chain-link or metal fence | $200 to $400 | Mesh and posts cleared of moss and rust film |
| Wood fence sealing (add-on) | $1.50 to $3.00 / linear ft | Repels water, slows moss regrowth |
| Fence plus deck package | $1,200 to $3,500 | Clean the fence and restore the deck together |
For comparison, replacing a wood fence costs $25 to $50 per linear foot, often several thousand dollars. Cleaning and sealing it every couple of years protects the wood for a small fraction of a replacement.
Different surfaces need different methods. Here is when each applies.

“Our cedar fence was solid green on the shady side. GreenTree made it look brand new and sealed it so it stays that way.”
“Cleaned a long vinyl fence that had gone dingy. It is bright white again and the price was exactly quoted.”
“Did the fence and gates, even the hard-to-reach back side. Great attention to detail.”
Our crew works throughout Portland, including the Pearl District, Sellwood, Hawthorne, Alberta, Laurelhurst, St. Johns, Multnomah Village, and Irvington, plus nearby Beaverton. Wherever you are in Multnomah County, the wet the Portland metro climate is the same. So the work follows the same yearly cycle, and we schedule accordingly. Founder Andreas Benavente set up that seasonal cadence so no Portland property gets missed.
Fence Cleaning in Portland works best as part of a full exterior plan. For that reason, many homeowners pair it with our fence cleaning service. They also book it alongside fence cleaning in nearby Beaverton for a rental or second property. GreenTree handles the scheduling, so the whole job lands in one visit.
Most fence cleaning in Portland runs $250 to $750. A standard backyard wood fence runs about $300 to $500, vinyl runs a little less, and adding a sealer on wood costs $1.50 to $3.00 per linear foot. The price depends on the length and material, and GreenTree locks the full figure in writing first. Cleaning costs far less than the thousands a fence replacement runs.
High pressure can. A pressure washer on full power gouges soft cedar and fir, raises the grain, and leaves a fuzzy, splintered surface. We soft-wash fences instead, using low pressure and a cleaner that lifts moss and gray without harming the wood. That gets the fence clean without the damage a careless pressure wash leaves behind.
Yes. Vinyl and composite do not rot, but they still grow the same green algae and collect a chalky film in Portland’s damp climate. We wash them with low pressure and a cleaner matched to the material, which restores the bright finish without etching the surface. Composite gets a gentle approach so we do not damage the texture.
Once a year keeps a Portland fence free of the moss and algae that the 43 inches of annual rain encourage. Shaded sides may need it more often. On a wood fence, pairing the yearly clean with a sealer every two to three years is the most cost-effective way to keep it bright and protected.
Yes, and on a wood fence it is worth it. Sealing after cleaning repels water and slows how fast moss and gray return, so the clean finish lasts much longer in Portland’s wet climate. We apply it for $1.50 to $3.00 per linear foot. A brightener can also even out the wood tone before sealing.
Yes, that is the most common reason Portland homeowners call. We pre-treat the fence with a solution that kills the algae, moss, and mildew at the root, then soft-wash it off. Killing the growth rather than just rinsing the surface is what keeps the green from returning within weeks.
Spring through early fall is ideal, when panels can dry between rain events, which matters most if you are sealing afterward. That said, a fence wash works year-round here. Many homeowners book a clean in spring to clear the moss that built up over the wet Portland winter.
A standard Portland backyard fence usually takes a few hours. A long or double-sided fence, or one that also gets sealed, can take most of a day since the wood needs to dry before sealer goes on. We give you a clear time window when we lock the quote.
Yes, when both sides are yours to clean and accessible. A fence often looks worse on the shaded side where moss thrives, so cleaning only one face leaves it half-done. Where a neighbor shares the fence, we clean your side and any shared face you have access to, and we confirm the scope at the quote.
The shaded side, usually facing north or under trees, stays damp far longer after Portland rain, and that is exactly what moss and algae need. The sunny side dries out and grows far less. We treat the whole fence so both faces match, with extra attention on the shaded panels.
Yes. GreenTree is Oregon CCB licensed and carries $2M in general liability coverage plus workers compensation, with documents on request. That protects your property if anything goes wrong, and it meets the vendor requirements most Portland HOAs and property managers set for contractors.
Yes, and it is often the best value. Many Portland homeowners pair a fence wash with a deck restoration, a house wash, or a driveway clean and have us handle it all in one visit. Bundling saves a trip charge and gets the whole exterior matching at once. We quote the package in writing up front.
