Professional Fence Cleaning
in Seattle & the Eastside
Green algae, gray weathering, and mildew take over Pacific Northwest fences fast — especially on shaded, north-facing runs. We clean every fence material safely, from delicate cedar to vinyl and chain-link, and can prep wood fences for staining.
Why Seattle Fences Turn Green, Gray & Grimy
Your fence takes the same Pacific Northwest beating your deck and siding do — constant moisture, shade, and tree debris — but it's often the last surface anyone thinks to clean. That's why fences tend to look the most weathered part of a property.
The green film is algae thriving on the shaded, damp sides that never fully dry. On wood and cedar, the gray, weathered look is oxidized surface fiber, and the dark blotches are mildew and tannin staining. On vinyl and composite, it's algae, mold, and a buildup of dirt and pollen that dulls the surface. North-facing runs and sections shaded by trees or the house itself always show it worst.
A clean fence does more than look better — it frames your whole property. When the fence is green and gray, even a freshly washed home reads as unkempt. Cleaning it is one of the fastest, most noticeable improvements you can make to curb appeal.
How We Clean Fences Safely — By Material
A vinyl fence and a cedar fence could not be more different to clean. We match the method to the material, every time.
Identify Material & Condition
Cedar, pressure-treated wood, vinyl, composite, or metal — each takes a different pressure and solution. We identify what you have and its condition before anything else, because that decision is what prevents damage.
Protect & Pre-Treat
We pre-soak surrounding plants and landscaping — fences sit right against gardens and lawns — and pre-treat heavy algae, mildew, and shaded runs so cleaning is even and thorough.
Material-Matched Cleaning
Wood and cedar get low pressure worked with the grain; vinyl and composite get a gentle soft wash; metal and chain-link get an appropriate rinse. The growth is killed at the root, not just rinsed off the surface.
Rinse, Inspect & (Optional) Brighten
We rinse thoroughly and inspect both sides. For wood fences headed for stain or seal, we can finish with a brightener that restores color and preps the surface for finishing.
Fence Materials We Clean
Every fence material has its own quirks — here's how we handle each one:
Cedar Fences
The most common — and most delicate — fence wood here. Low pressure, worked with the grain, removes gray and mildew without raising the grain or splintering.
Pressure-Treated Wood
More durable than cedar but still needs controlled pressure. We clean off graying, mildew, moss, and tannin staining safely.
Vinyl Fencing
Soft washed at low pressure to lift algae, mold, and dirt from panels and posts without scratching or dulling the finish.
Composite Fencing
Rot-proof but still grows mold and algae in shade. Cleaned gently to remove growth and staining without marring the surface.
Chain-Link & Metal
Chain-link, wrought iron, and metal panels cleaned of oxidation, rust staining, and biological buildup at appropriate pressure.
Masonry & Mixed Fencing
Block, brick, and stone fence walls — and mixed-material fences — cleaned to remove moss and staining from every surface.
Fence Problems We Solve
Green Algae
The green film on shaded, north-facing runs — killed at the root so it doesn't return in a few weeks.
Gray, Weathered Wood
Oxidized surface fiber cleaned and, if you like, brightened back to the wood's natural color.
Mildew & Tannin Stains
The dark blotches on wood fencing lifted with the right cleaning and brightening chemistry.
Dirt, Pollen & Dulling
The buildup that flattens the look of vinyl and composite fencing, washed back to a clean finish.
Rust & Oxidation
Rust staining and chalky oxidation on metal and chain-link fencing cleaned away.
Staining & Sealing Prep
Wood fences cleaned and brightened so a stain or seal absorbs evenly and lasts.
Excellent work — they went above and beyond on our concrete and fence. Our neighbors are already asking who we used. Highly recommend Homefront in Shoreline.— David M., Shoreline, WA · Concrete & Fence Cleaning
What Does Fence Cleaning Cost in Seattle?
Fence cleaning cost depends on the total linear footage, the material, its condition, and whether you want a straight clean or a clean-and-brighten prep for staining. We provide transparent, itemized quotes — and cleaning your fence alongside a house wash or deck cleaning lowers the overall cost.
Length & Material
Linear footage and the fence material set the scope and the right method. We measure for an accurate quote.
Condition
Heavy graying, established algae, or deep mildew need extra cleaning and dwell time, accounted for upfront.
Bundle & Save
Fences pair naturally with deck, siding, and house washing. Combining surfaces on one visit is the best value.

Frequently Asked Questions
Can you clean a fence without damaging it?
Yes — the key is matching the method to the material. Wood and cedar fences need low pressure and a gentle, with-the-grain approach so we don't raise the grain or splinter the boards. Vinyl and composite clean easily at low pressure. Chain-link and metal are more forgiving. We assess your fence first, then use the right pressure and solution for that material.
How often should I clean my fence in the Seattle area?
For most Pacific Northwest fences, every 1–2 years keeps growth from taking hold. Our damp, shaded climate grows green algae and mildew fast — especially on the north-facing sides and shaded runs that never fully dry. Cedar and wood fences that are sealed or stained hold up longer between cleanings; bare wood benefits from more regular attention.
Can you remove the green film and black staining from my fence?
Yes. The green film is algae and the darker staining is usually mildew and tannin — both thrive on shaded, damp fencing. We clean with solutions that kill the growth at the root rather than just rinsing off the surface, so it clears fully and stays clean far longer than a quick DIY spray-down.
Do you clean vinyl and composite fences?
Absolutely. Vinyl and composite fencing don't rot, but they still grow algae, mildew, and mold in the shade, and collect dirt and pollen. We soft wash them at low pressure to remove all of it without scratching or dulling the surface.
Can you prep my wood fence for staining?
Yes — a freshly cleaned and brightened wood fence is the ideal surface to stain or seal. We remove graying, mildew, and contaminants and can brighten the wood so a finish absorbs evenly. If refinishing your fence is the goal, cleaning is the essential first step.
