Deck & Patio Cleaning in Jacksonville, FL
Jacksonville’s heat, humidity, and afternoon rain turn outdoor surfaces green within a single season. Wood decks, concrete patios, pavers, and composite boards all need different pressure and chemistry — one wrong setting causes more damage than a decade of rain.

The Wrong Pressure Setting Costs More Than a New Deck
A pressure washer set too high strips the wood grain from a pine deck, splinters composite boards, blows sand from between pavers, and scours the surface of concrete. Most DIY deck damage happens not from neglect but from overcorrecting — a rented machine at full pressure does in thirty minutes what would take years of weathering.
We calibrate every deck and patio job to the material, age, and contamination level of that specific surface. Wood gets wood-appropriate pressure. Composite gets composite-appropriate pressure. Pavers get a surface cleaner and joint-safe settings. There is no universal setting.
Signs Your Deck or Patio Needs Cleaning Now
- Green, black, or gray discoloration on any boards or slabs
- Slippery surface when wet — algae biofilm
- Darkened wood that no longer looks its original color
- White chalky haze on concrete or pavers (efflorescence)
- Mold or mildew growing in deck board gaps
- Staining under patio furniture or grills
- Surface that was sealed 12+ months ago and looks dull
Surface Types We Clean
Each material has a different pressure tolerance, cleaning chemistry, and drying requirement. We match our approach to your surface.
🪵
Wood Decks
Pine, cedar, and pressure-treated boards need low-to-medium pressure with a wide fan tip. We clean with the grain, never across it. Heavy mildew gets a soft wash pre-treatment so chemistry does the work — not brute force.
⚙️
Composite & Trex
Composite boards scratch and haze under too much pressure. We stay under 1,500 PSI with a fan tip held at safe distance. Composite still grows algae and mildew — especially on north-facing or shaded decks — and needs periodic cleaning to maintain the manufacturer’s appearance warranty.
🧱
Concrete Patios
Concrete tolerates higher pressure but age and condition matter. New concrete needs gentler treatment; older slabs handle 2,500–3,000 PSI with a surface cleaner for streak-free results. We also treat efflorescence — the white mineral haze that forms on Jacksonville concrete from humidity cycling.
🧧
Brick & Pavers
Pavers need careful pressure management to avoid displacing polymeric joint sand. We use a surface cleaner at controlled settings and avoid directing the stream at joints. After cleaning, we can recommend whether re-sanding and re-sealing is needed.
⭐
Pool Decks
Pool decks combine slip-hazard algae with pool chemical residue and bare feet — they need thorough cleaning with solutions safe for pool water. We protect drains and use biodegradable chemistry appropriate for the surface and the environment around it.
Our Deck & Patio Cleaning Process
No two jobs use exactly the same settings. Here’s how we approach every deck and patio we clean in Jacksonville.
Step 01
Surface Assessment
We identify the material, check for damage, assess contamination level, and note any areas — cracks, loose boards, damaged grout — where pressure could cause problems. You get a clear picture of what we’re going to do before we start.
Step 02
Pre-Treatment
For surfaces with algae, mold, or mildew we apply a biodegradable cleaning solution and let it dwell. This breaks down the biological growth at the root so the wash cycle removes it completely rather than just the top layer. Nearby plants get wetted before and rinsed after.
Step 03
Calibrated Wash
PSI, nozzle angle, and working distance are set for the specific material. Wood and composite get fan tips at safe distance. Concrete and pavers get a surface cleaner for even, streak-free coverage. We never use a turbo nozzle on decking.
Step 04
Final Rinse & Walkthrough
A clean-water rinse removes all solution residue. We walk the entire surface with you to confirm the result. If anything needs a second pass, we do it before we leave — not after you call us back.
Deck & Patio Cleaning FAQs
How often should I clean my deck in Jacksonville?
Once a year is the baseline. Wood decks in shaded areas or near tree canopy may need cleaning every 6–8 months. Composite decks in open, sunny spots can often go 12–18 months. Concrete patios vary — pool decks typically need annual or biannual cleaning due to pool splash and bare-foot traffic.
Will pressure washing damage my composite deck?
It can if done wrong. Composite scratches and hazes under direct turbo nozzles or pressure above 1,500 PSI. We use fan tips at appropriate distance and never use a rotary nozzle on composite. Most composite manufacturers require periodic cleaning to maintain the appearance warranty — using the right method protects that warranty rather than voiding it.
Should I seal my deck after cleaning?
For wood decks, yes — cleaning is the right first step before sealing or staining. Sealant applied over algae or mold won’t bond properly and peels prematurely. Allow the wood to dry fully for 48–72 hours after cleaning before applying any coating. We’ll tell you honestly whether the wood is in a condition where sealing makes sense.
Can you clean around my outdoor furniture and grill?
Yes. We move lighter items and work around built-in features. If you want to clear the deck yourself before we arrive, that speeds things up — but it’s not required. We’ll work with whatever’s there.
Will cleaning remove oil or rust stains from my patio?
Biological stains — algae, mold, mildew — come out fully. Oil stains from grills or cars are tougher; we apply a degreaser treatment, but deep oil penetration may lighten rather than fully disappear. Rust stains from metal furniture require a separate acid-based treatment — we’ll let you know upfront what’s realistic for your specific staining.
Is the cleaning solution safe for my pets and plants?
We use biodegradable solutions and pre-wet all surrounding plants and grass before applying anything. We ask that pets be kept indoors during the wash and for about an hour after while surfaces dry. Once dry, everything is safe for normal use.
