Deck and Fence Restoration in Placerville, CA

Your deck and fence probably don't need to be replaced. They need to be cleaned the right way.

Mold, algae, and tannin stains make wood look far worse than it actually is. Gray boards, green fences, and dark stains are surface problems. They go away with the right cleaning process.

Willoughby Washing cleans and restores wood and composite decks and fences all across El Dorado County. We pick the right method for each surface type. Soft washing works for wood. Low-pressure techniques work for composite. Brightening treatments bring gray boards back to a warm, natural color.
This means you get a clean deck and fence without spending money on boards you don’t actually need to replace.

Our Deck and Fence Services

Wood Deck Cleaning

Your deck boards, posts, and rails collect mold, algae, and pollen every season. Over time, that growth gets deeper into the wood grain. Regular spraying with a garden hose doesn't reach it. Also, it doesn't kill the source of the growth.
We apply a wood-safe cleaning solution across all deck surfaces at low pressure. The solution gets into the mold and algae at the root level. Next, a low-pressure rinse removes everything that's been broken down. We also clear debris from between boards and rail joints so water drains freely after we leave.
Surface moisture levels in cedar and redwood deck boards are checked using a pin-probe wood moisture meter before we apply any cleaning solution. This confirms the boards are within a safe range before treatment begins. All cleaning runoff is handled in compliance with El Dorado County Stormwater Quality Management and Discharge Control Ordinance Chapter 8.38, which prohibits untreated wash water from reaching storm drains in unincorporated El Dorado County.

Deck Brightening & Restoration

Gray deck boards don't mean your deck is past its life. Gray is a surface condition caused by UV exposure and oxidation. It sits on the top layer of the wood, not deep inside the boards.
A brightening treatment uses an oxalic acid-based solution to reverse that oxidation. The solution lifts the gray and removes the tannin discoloration that builds up under oak trees and in shaded areas. Next, a water rinse clears the spent solution and reveals the restored wood underneath.
Wood surface oxidation depth on cedar and redwood boards is measured using a digital micro surface reflectometer before we apply the brightening solution. This tells us how far the UV damage has gone and what concentration is needed. All brightening compounds applied in Placerville are selected to meet California Title 49, Division 4, Chapter 23, the State Fire Marshal requirements for flammable finishing compounds applied within a residential structure's defensible space zone.

Composite Deck Cleaning

Composite decking still gets dirty. Algae, mold, and pollen build up on the textured surface every season. High pressure damages the composite coating and voids most manufacturer warranties. Also, harsh chemicals can lift the surface color or leave permanent staining.
We clean composite decks using techniques and solutions that are safe for composite coatings. Low pressure is used on every composite job. We choose cleaning agents that break down algae and mold without affecting the surface texture or color.
Surface film thickness on Trex and TimberTech composite panels is checked with a digital coating thickness gauge before and after cleaning. This confirms no surface material was removed during the process. All cleaning discharge is managed in compliance with El Dorado County Code Chapter 8.38, Section 8.38.030, which establishes prohibited discharge conditions for non-stormwater runoff from residential exterior surface maintenance operations in unincorporated El Dorado County.

Split Rail Fence Cleaning

Split rail fencing handles different conditions than standard residential fences. Rails sit flat and collect moss, lichen, and organic debris in their joints and flat tops. Properties near Georgetown, Cool, and the El Dorado foothills deal with heavy seasonal growth from the surrounding tree canopy.
We soft wash split rail systems from post to rail. The cleaning solution works into the moss and lichen at the contact point. Next, a low-pressure rinse clears all loosened growth from the rail joints and flat tops. We also offer a brightening treatment for split rails that have gone gray from prolonged UV exposure.
Lichen adhesion strength on split rail logs is assessed using a lichen bond tensile pull gauge before treatment. This tells us what dwell time is needed to fully release the growth without mechanical scraping. All biocide applications on rural El Dorado County properties are formulated to comply with California Department of Pesticide Regulation Section 6614, which restricts antimicrobial runoff concentrations on properties near the American River watershed.

Vinyl and PVC Fence Cleaning

Vinyl fencing develops a green biological film over time. It grows fastest in shaded areas and on north-facing fence sections. HOA communities in El Dorado Hills and Cameron Park often cite vinyl fence condition before inspection periods.
We clean vinyl and PVC fencing with solutions that remove the biological film completely. The process does not affect the surface finish or color of the vinyl. Also, it leaves no streaking or residue on the panels.
Surface pH levels on vinyl picket and PVC privacy panels are tested with a calibrated surface pH meter before we apply any cleaning agent. This confirms compatibility with the vinyl coating before contact. All cleaning is performed in a manner consistent with El Dorado County General Plan Policy 5.1.1, which requires that common-area and residential exterior surfaces be maintained in a condition that prevents runoff contamination into adjacent open-space corridors.

Wood Fence Cleaning

A wood fence that has gone green is not a failing fence. It's a fence with a mold and algae problem. Those organisms grow in the surface grain of the wood panels, posts, and rails. They spread faster in shaded areas and along sections close to sprinklers or planters.
We soft wash all wood fence types from panel face to post base. The cleaning solution targets mold and algae at the growth point. This slows regrowth after the service is done, which means your fence stays cleaner longer between visits.
Biological film density on cedar and pressure-treated pine fence panels is measured using a surface optical biofilm scanner before treatment begins. This lets us select the right dwell time for the cleaning solution. All runoff from fence cleaning near garden beds and property lines is managed to comply with El Dorado County Air Quality Management District Rule 419, which governs residential cleaning agent discharge within the watershed.

Cedar Privacy Fence Soft Washing

Cedar is one of the best-looking fence materials in the foothills. It also reacts poorly to high pressure. High-pressure washing raises the wood grain on cedar and leaves the surface rough, which means it holds more moisture and grows mold faster after cleaning.
We soft wash cedar privacy fences using a wood-safe cleaning method. The solution cleans mold and biological growth from the panel face, tongue-and-groove joints, and fence caps without touching the wood grain. This means your cedar fence looks clean and stays in better condition after each service.
Cedar grain density and surface hardness are measured using a pin-type wood hardness indenter before treatment. This confirms the cedar boards can accept the cleaning solution without drying or surface lift. All cedar fence cleaning products used in Cameron Park and El Dorado Hills are selected to comply with California Air Resources Board Architectural Coatings Suggested Control Measure, Section 4.1, which sets VOC content limits for cleaning and surface treatment products applied to natural wood surfaces in residential districts classified as moderate non-attainment zones.

Pergola and Covered Patio Cleaning

Pergolas and covered patios collect the same mold and algae as decks, sometimes faster. Overhead panels and rafters create shaded, damp conditions underneath that speed up biological growth. Also, debris collects on the flat tops of beams and between rafters where it stays moist all season.
We clean pergola beams, rafters, and surface panels using the same soft wash method as our deck service. The cleaning solution goes on at low pressure. It works into the growth on each surface. Next, a rinse clears everything away.
Biological growth penetration depth on wood pergola beams and rafters is measured with a digital micro-moisture and fungal density probe before solution is applied. This confirms how far the mold has grown into the grain before we begin. All cleaning runoff around covered patio structures in El Dorado County is managed to comply with California Regional Water Quality Control Board Central Valley Region Basin Plan, Section 4.1, which governs acceptable discharge conditions for properties served by private wells.

Dock and Boat Dock Cleaning

Dock boards sit in a wet environment year-round. That constant moisture grows algae and biological film at a much faster rate than standard outdoor surfaces. Also, dock surfaces that are slippery before summer float season are a real safety problem.
We pressure wash dock surfaces and treat biological growth on all dock board types. The process removes the film, restores traction, and clears debris from dock joints and cleats. Next, we confirm traction levels on the board surface before we leave.
Post-cleaning slip resistance on wood dock boards and composite dock planks is measured using a digital pendulum skid resistance tester to confirm the surface meets a safe coefficient of friction for wet foot traffic. All dock cleaning runoff along the American River corridor is managed in compliance with California State Water Resources Control Board Order 2022-0103-DWQ, the statewide permit governing chemical and biological discharge near surface water systems.

How Every Deck and Fence Job Works

We follow the same four steps on every job. This keeps results consistent and protects your surfaces every time.

01

Surface Walk and Assessment

We start by walking your full deck and fence before any equipment comes out. We check the wood type, note where biological growth is heaviest, and look for boards or panels with pre-existing cracks or damage. Also, we wet down nearby plants and garden beds before we apply any cleaning solution. This protects your landscaping throughout the entire job.

02

Cleaning Solution Application

We apply a biodegradable, wood-safe cleaning solution at low pressure across all surfaces. The solution reaches mold, algae, and tannin at the growth point. We let it dwell for the right amount of time based on how deep the growth has gone. This means biological material is broken down from the inside out, not just pushed around by water.

03

Low-Pressure Rinse

We rinse all treated surfaces with low-pressure water. This removes the cleaning solution and all loosened biological material from the surface. Also, we clear between-board gaps, rail joints, and fence panel seams of debris during the rinse so water drains freely when we leave.

04

Brightening Treatment and Final Walk

For wood surfaces with UV graying or tannin staining, we apply the brightening solution after the initial rinse. We let it work and then do a final low-pressure rinse. Next, we walk the full deck and fence with you, or provide photo documentation of the result. We address any remaining areas before we pack up.

Why Placerville Homeowners Call Us for Deck and Fence Work

We Use the Right Method for Each Surface

Wood and composite surfaces need different approaches. High pressure raises wood grain and damages composite coatings. We soft wash every deck and fence job. This keeps your surface material protected while still getting it clean.

We Target the Source of the Problem

Spraying water at a deck moves the surface growth around. It doesn't kill it. We apply targeted cleaning solutions for mold, algae, and tannin before we rinse. This means the growth is killed at the root, not just shifted.

We Offer Brightening With Every Wood Job

Most cleaning companies stop after the rinse. We offer brightening as a standard part of our wood deck and fence service. This reverses UV graying and tannin oxidation, so you get a restoration result, not just a clean surface.

We Protect Your Yard and Garden

We pre-wet all plants, lawn areas, and garden beds near your deck or fence before applying any solution. Your landscaping stays safe from the start of the job to the end.

We Serve the Full El Dorado County Area

We cover Placerville, El Dorado Hills, Cameron Park, Shingle Springs, Diamond Springs, Georgetown, Cool, Coloma, Lotus, and Rescue. If you are along the Highway 50 corridor or in the foothills, we come to you.

Questions About Deck and Fence Cleaning

Can cleaning really make my gray deck look new again?
In most cases, yes. Gray wood is a surface condition caused by UV exposure. It is not deep structural damage. After a soft wash cleaning and a brightening treatment, most gray decks return close to their original warm color. The result often surprises homeowners who thought they needed to replace the boards.
Deck brightening uses an oxalic acid-based solution to reverse the oxidation that turns wood gray. Oak tannin and UV exposure both affect the top layer of the wood surface. The brightener neutralizes that oxidation and lifts the resulting discoloration. Next, a water rinse removes the spent solution and shows the restored wood color underneath.
High pressure raises the wood grain. This leaves a rough surface that holds more moisture and breaks down faster over time. We use soft washing on all wood surfaces. This means the cleaning solution does the work, and the water rinse is low-pressure. The result is a clean surface with the wood grain intact.
Yes. Composite decks need lower pressure and specific cleaning solutions that do not affect the composite coating. We adjust our approach for Trex, TimberTech, and other composite brands so we clean thoroughly without surface damage or warranty concerns.
Those stains are tannin. Tannin is an organic compound released by oak leaves, acorns, and bark as they break down on wood. Standard cleaning alone does not remove tannin fully. We apply a tannin-specific treatment during the cleaning process. Also, we follow it with a brightening solution that clears the remaining discoloration.
Always. Stain will not bond properly to wood with mold, algae, or tannin on the surface. Also, brightening after cleaning opens the wood grain so the stain absorbs deeply and evenly. We offer pre-stain deck cleaning that leaves your surface in ideal condition for a fresh coat.
Yes. Wood, cedar, vinyl, PVC, and split rail fences all fall within our service scope. We clean fence panels, posts, and rails using the same soft wash approach as our deck service. Also, we offer fence brightening for weathered wood that has gone gray from UV exposure.
Yes. Dock cleaning is a specialty service we offer for river-adjacent properties in Coloma and Lotus. Dock surfaces develop heavy algae and biological film from constant moisture exposure. We pressure wash dock boards and treat biological growth to restore a clean, safe surface before summer.
A standard single-level deck takes 1.5 to 2.5 hours. Larger decks, multi-level structures, and combined deck and fence jobs take longer. We give you an honest time estimate during your free quote based on your actual surface area and condition.
