Pool Deck Cleaning in Orlando, FL

Orlando Pool Deck Cleaning — What’s Actually Growing on Your Deck

Most homeowners who call about a green or black pool deck have already tried something — the garden hose, a pressure washer rental, a bottle of pool deck cleaner from Home Depot. And the growth came back, usually within four to eight weeks. The reason is always the same: whatever method they used removed the visible layer. The organism itself — rooted in the pores of the surface — was never touched.

What to Avoid

What causes my Orlando pool deck to go green so fast after cleaning?

Green algae (Chlorophyta) lives in the micro-pores of concrete, travertine, and paver surfaces. A pressure rinse removes the visible layer — the organism stays embedded and regrows in 4–8 weeks in Central Florida’s continuous warmth and humidity. A screened lanai makes this worse by trapping moisture and diffusing sunlight to the indirect range algae prefers. Pre-treatment with biodegradable algaecide chemistry kills the organism at the root before the surface clean removes the dead material. The pool deck stays clean for 6–12 months instead of 4–8 weeks. If yours went green within two months of a professional cleaning, the pre-treatment was skipped or under-diluted.

Will pressure washing damage my travertine pool deck?

Yes — if done at the wrong PSI. Travertine is a natural porous limestone that begins to erode at anything above 800 PSI. High-pressure washing at 2,000+ PSI can permanently pit and roughen the stone. Strong acid chemistry used for calcium removal on concrete will etch travertine if not carefully neutralised and rinsed immediately. We clean travertine at 500–800 PSI maximum with pH-neutral or carefully matched chemistry and extended dwell time. If any operator quotes “pressure washing” for your travertine deck without specifying a PSI limit under 800, ask them directly before they start.

What is Kool Deck and can it be pressure washed?

Kool Deck is a trademarked Mortex Corporation product — a spray-applied acrylic texture coating over concrete, patented in 1965. It keeps pool deck surface temperatures 30+ degrees cooler than bare concrete in direct Florida sun. Under anything above 600 PSI, the texture strips permanently. The concrete beneath is bare, smooth, and significantly hotter. Recoating costs far more than a correct cleaning. We soft-wash all Kool Deck and cool-deck coatings at 400–600 PSI maximum. If you are unsure whether your deck has a Kool Deck coating, tell us at booking — we identify it before we touch anything.

What causes orange staining on my pool deck near the sprinkler heads?

Iron oxide — rust deposited by Florida’s mandatory irrigation water. Central Florida groundwater carries dissolved iron. Every irrigation cycle deposits a trace amount on whatever surface the water hits. Over months it builds into visible orange-brown staining. Pressure washing alone cannot remove iron oxide because it is chemically bonded to the surface. Oxalic acid pre-treatment converts the iron compound to a water-soluble form that rinses away. We carry and apply rust pre-treatment on every job where orange staining is present. Results depend on how long the staining has been present — we describe the realistic outcome before we start, not after.

What causes the chalky white deposits around the edge of my pool deck?

Calcium efflorescence from pool water splash. Pool water contains dissolved calcium carbonate. Every time splash water lands on the deck and evaporates, it leaves a thin calcium deposit. Over months of daily pool use in a Florida summer, it builds into the white-grey crust you see forming along the pool edge and on the pool steps. The treatment is different from rust staining — calcium responds to a slightly acidic cleaning chemistry that must be matched carefully to the deck surface to avoid etching.

How much does pool deck cleaning cost in Orlando?

A standard concrete pool deck of 400–800 sq ft runs $200–$320. Travertine at the same size runs $280–$440 due to the lower-speed specialist technique required. Paver decks start at $200 clean only and $280+ with joint sand restoration. Rust pre-treatment adds $50–$100. Calcium treatment adds $50–$100. Pool cage screen soft wash on the same visit adds $100–$200. Full property bundles — pool deck, driveway, and house wash — average $450–$950. A quote under $100 for a standard pool deck is a consumer pressure washer with no chemistry and no pre-treatment. The growth comes back in six weeks.

How often should I clean my Orlando pool deck?

Concrete pool decks in a screened lanai need cleaning every 8–12 months in Central Florida. Open-lot decks in full sun go 12–18 months. Travertine near water — Windermere and Dr. Phillips — needs attention every 6–10 months due to the moisture loading from lake proximity. Paver decks under heavy canopy in Baldwin Park or College Park may need cleaning every 4–8 months. HOA community pools typically need annual cleaning to maintain compliance.

Can you clean my pool deck without getting chemicals in the pool?

Yes. Before any chemistry is applied to the deck, we pre-wet and barrier the pool edge, control runoff direction away from the pool, and assess wind direction before applying any spray chemistry. We flush the deck with fresh water after the pre-treatment dwell period, before the surface clean. Biodegradable chemistry breaks down rapidly on contact with water. We have never had a pool chemistry issue from a cleaning job. We tell you specifically what we are applying and how we are containing it before we start.

What is the best time of day to schedule a pool deck cleaning in Orlando?

Morning — before 10 AM. Concrete and travertine pool decks cleaned in morning Florida sun dry in 2–4 hours for open decks and 4–6 hours for screened lanais. Schedule morning and your pool area is ready by early afternoon. Decks cleaned in the afternoon during Florida summer can still be damp at sunset — the afternoon storm pattern from June through September reduces UV drying significantly. If you have a pool event, book the cleaning 2–3 days prior to allow full drying and optional sealer cure time.

Why hire a licensed pool deck cleaning operator instead of a cheap contractor?

A licensed Florida business — verifiable at Sunbiz.org — carries $1,000,000 general liability and active workers’ compensation. If an uninsured worker is injured on your pool deck, your homeowner’s insurance absorbs the liability. Beyond insurance: the equipment difference is significant. A licensed pool deck operator brings a rotary surface cleaner, downstream chemical injector, oxalic acid rust pre-treatment, biodegradable enzyme degreaser, and the experience to identify what your surface is and what PSI it can handle. A rented consumer pressure washer with no pre-treatment chemistry is how Kool Deck gets stripped and travertine gets pitted. The repair bill is always more than the original cleaning cost.

“The orange staining near my sprinkler heads had been there for three years. Every company I called said pressure washing would handle it. These guys explained that iron oxide needs a separate treatment before the surface clean, applied the oxalic acid pre-treatment, and the staining reduced by about 85%. They told me upfront the remaining 15% was too deep to fully remove. That honesty is genuinely rare in this market.”

“Our Kool Deck was stripped by a previous cleaner who used too much pressure. We did not know it was Kool Deck until we called and they identified it from our description before they even came out. They explained exactly what happened, what could be done, and what to expect. The deck looks significantly better. The previous damage from the other company is still there — but they were honest about that too.”

“HOA violation notice for black mold on our screened pool deck. 18 days to fix it. These guys came out three days after I called, completed the full pool deck and screen enclosure clean, gave me before-and-after photos the same day, and I submitted them to the Celebration Foundation that evening. Violation closed four days later.”
