Decks
Deck Cleaning in San Diego
Standard deck cleaning covers wood decks, composite decking and fencing: we clear the area, protect plants, apply a material-appropriate cleaner and rinse at low pressure. This removes surface dirt, mildew and organic buildup while protecting the grain and finish. On wood, a brightening stage is added where applicable.
Sanding, refinishing, staining and sealing are not part of every deck cleaning. They are quoted separately, only when the wood needs them and you choose to include them.

What this solves
Common problems we see
- Wand marks, striping, and fuzzed grain from previous pressure washing
- Green or black growth on shaded sections and stair treads
- Tannin bleed and rust streaks around fasteners and planters
- Composite decking with a dull chalky film and mildew in the embossing
- Fences that are green on the neighbor-facing side and gray on yours
Scope
What's included
- Full clear of furniture, planters, and rugs from the working area
- Plant and landscape protection with pre-wet and post-rinse
- Wood-appropriate cleaner and, where needed, a brightening stage
- Low-pressure rinse with fan tips, never a turbo nozzle on wood
- Composite-specific cleaning that respects the cap layer
- Stain or penetrating sealer available as a separately quoted return visit once fully dry
Our process
What standard deck cleaning includes — finishing quoted separately
01
Board survey
We check for soft boards, popped fasteners, and rot at ledger and post bases, and flag anything that needs a carpenter.
02
Protect
Landscape, siding, glass, and lighting are protected and pre-wet before any solution goes down.
03
Clean
The cleaner does the work with dwell time and agitation — pressure is not the tool that removes growth.
04
Rinse
Even, low-pressure rinse worked with the board direction so nothing stripes.
05
Brighten
On wood, a brightener neutralizes and returns natural color before any coating.
06
Optional: seal or stain
Only if you have chosen a separately quoted finish — we return once the moisture content is low enough for it to bond.
In detail
Protect what you've invested in
Your deck, fences, and outdoor wood surfaces should look clean, safe, and well-maintained — not covered in dirt, algae, and buildup.
We provide professional deck cleaning services in San Diego, including wood deck cleaning, composite decks and fences, using low-pressure methods chosen to avoid surface damage. Sealing, staining and restoration are separately quoted services.
What we clean
- Wood decks
- Composite decks (Trex, TimberTech, and similar)
- Wood fences
- Outdoor wood furniture
- Railings
- Stairs
- Balcony wood surfaces
Why wood surface cleaning matters
- Slippery buildup creates safety hazards — algae and mildew make decks and wood surfaces slick and unsafe.
- Protect your wood and finishes — improper cleaning or high pressure can permanently damage wood, causing splintering, streaking, and premature wear.
- Prevent fading, rot, and deterioration — dirt, moisture, and organic buildup break down wood over time if left untreated.
- Keep your outdoor space looking clean and guest-ready across the whole backyard.
Wood vs. composite cleaning
Not all materials should be treated the same. Wood cleaning uses gentle methods to protect the natural grain and prevent splintering and surface damage. Composite cleaning uses low pressure to avoid streaking and fading, safe for manufactured decking materials.
Fence panels, gates, wood seating, tables, and outdoor wood features are restored the same way, bringing back a clean, uniform look across your entire yard.

- Sanitizing of contaminated surfaces
- Urine and odor treatment where applicable
- Organic buildup removal
- Low-pressure, material-safe cleaning methods
Materials & capabilities
What we restore, and what we don't promise
Every board type takes a different route. Here is how we treat each one — and where restoration stops and carpentry begins.
Softwood decking
Redwood, cedar, and pressure-treated pine clean and brighten well and take a penetrating stain or sealer. These are the boards where the difference between a wash and a restoration is most visible.
Tropical hardwood
Ipe, cumaru, and similar dense hardwoods are cleaned gently and oiled rather than sealed with a film. Expect deep color back, not a glossy coating.
Composite and PVC
Trex, TimberTech, and PVC boards are cleaned with composite-safe products that lift mildew from the embossed grain. No stripping, no sanding, no sealer — those damage the cap layer.
Fencing, gates, and screens
Wood fencing, gates, and privacy screens are cleaned on both faces where access allows, with the shaded side treated for the heavier growth it always carries.
Railings, stairs, and pergolas
Deck railings, stair treads and stringers, and pergola posts inside the same footprint are handled by hand so nothing is left half-finished at the edges.
What restoration cannot fix
Rot, structural movement, and failing ledger connections need a licensed contractor. Badly fuzzed boards from earlier pressure washing need sanding or replacement, and sealer in full coastal sun lasts one to two years, not five.
Pricing
What deck restoration costs
Quoted based on your space, condition, and scope. Staining or sealing is quoted separately as a return visit once the wood is dry. Fences and gates can be priced on their own or bundled with the deck.
What moves the price
- Square footage, stair count, and railing linear footage
- Current condition — light mildew versus years of greying and growth
- Wood versus composite, and the board species involved
- Whether sanding, staining, or sealing is required
- Access, and how much furniture and planting must be moved and protected
San Diego conditions
Decks here fail from the edges in
Coastal moisture, shaded canyon lots, hard UV, and a dry-then-drenched seasonal swing all age outdoor wood differently. Most of our deck and fence work happens in La Jolla, Del Mar, Carmel Valley, Encinitas, Rancho Santa Fe, Coronado, and the surrounding neighborhoods.
Coastal moisture and mildew
Encinitas, Solana Beach, and Point Loma decks carry heavier mildew loads on shaded and north-facing boards year round.
Canyon and shaded properties
Leaf litter packs into board gaps, holds water against end grain, and stains the wood beneath it.
Sun, dry summers, winter rain
Intense UV bleaches horizontal boards far faster than railings, and the swing from parched summer to concentrated winter rain opens checks and lifts film finishes.
Sprinkler damage
One misaimed head will rot a bottom fence rail or post base long before the rest of the structure ages. We flag it when we see it.
Maintenance
Keep the finish, skip the restoration
A deck that is washed once a year and has its board gaps cleared holds a finish far longer, which is where the real cost sits — recoating a tired sealer is straightforward, stripping a failed, peeling one costs several times more. If water no longer beads on the boards, the sealer is spent.
Recurring patio maintenance can be scheduled whenever the deck is already in a condition you want maintained. Restoration is only recommended when the wood or finish needs more extensive work.
