Professional Pressure Washing in Key West, FL

Under The Sun Property Care provides professional pressure washing for homes, driveways, commercial properties, and outdoor surfaces throughout Key West and the Lower Florida Keys. Our certified technicians use commercial-grade equipment to remove marine algae, mold, mildew, salt film, and tropical buildup that accumulates on properties in Monroe County's coastal climate. Whether you need a one-time exterior refresh or a recurring maintenance plan, we bring the right equipment and the right technique to every job — and we serve the full corridor from Key West to Big Pine Key.

What We Pressure Wash in Key West

We provide pressure washing for a wide range of residential and commercial surfaces:

Home Exteriors

Stucco, painted concrete block, and Hardie board siding all accumulate mold and algae in Key West's humidity. A thorough exterior wash restores curb appeal and protects the surface from long-term deterioration caused by organic growth.

Driveways & Parking Areas

Concrete and paver driveways in the Keys turn green fast from algae and mildew. We clear buildup, remove oil stains, and restore the clean surface underneath — with results that are immediately visible.

Pool Decks & Patios

Wet environments around pools breed slippery algae and mold. Pressure washing pool decks removes that growth and restores safe, clean footing — important for both homeowners and vacation rental guests.

Fences & Walls

Wood, vinyl, and concrete block fences take on salt haze and organic staining in the coastal environment. We clean them without damaging the surface or stripping paint.

Sidewalks & Walkways

High-traffic walking surfaces accumulate grime and biological growth that can become a slip hazard. Clean walkways also make a strong first impression for rental properties and businesses.

Commercial Properties

Storefronts, restaurant exteriors, hotel facades, and commercial parking lots. We work around your business hours and offer recurring contracts for commercial clients who need consistent maintenance.

Boat Docks & Marine Structures

Dock surfaces and marine-adjacent structures collect some of the heaviest biological buildup in Monroe County. We use appropriate pressure and technique for treated wood, composite decking, and concrete dock surfaces.

Why Pressure Washing Matters in the Florida Keys

Key West isn't like the rest of Florida. The combination of salt air, high humidity, intense UV exposure, and tropical rainfall creates conditions where mold, algae, and mildew grow year-round on virtually every outdoor surface.

Salt air deposits accumulate on exterior walls, windows, and hard surfaces within weeks of a cleaning. Left untreated, salt film traps moisture against surfaces and accelerates oxidation and deterioration.

Marine algae and mildew thrive in the Keys' warm, humid environment. The green and black biological growth common on driveways and home exteriors isn't just unsightly — it creates slippery surfaces and, on porous materials like stucco and concrete, can penetrate and cause structural damage over time.

Hurricane season adds another dimension. Storms deposit debris, organic matter, and contaminants across every outdoor surface. Post-storm pressure washing removes this buildup before it has time to set and stain.

Vacation rental standards make regular exterior cleaning essential for Airbnb and VRBO hosts. Guest photos go public. Exterior appearance directly affects review scores, and a property that looks clean and well-maintained books more consistently.

Our Pressure Washing Process

Step 1 — Surface Assessment

Before we use any equipment, we walk the property and assess each surface. Not everything gets the same treatment. Concrete driveways handle high pressure well. Historic wood-frame homes and painted surfaces may need soft washing instead. We make that call on-site so nothing gets damaged.

Step 2 — Preparation

We protect surrounding landscaping, plants, and any surface that shouldn't get wet. Nearby vehicles are noted, outdoor furniture is moved if needed, and downspout drainage is checked before we start.

Step 3 — Wash & Rinse

Commercial-grade pressure washing equipment delivers the right PSI for each surface. We work systematically, section by section, ensuring even coverage. For surfaces with heavy biological buildup, we may apply a pre-treatment solution before the pressure wash to break down growth at the root.

Step 4 — Final Walkthrough

We walk the completed job with you — or document it with photos for absentee owners — to confirm results before we leave.

Frequently Asked Questions — Pressure Washing in Key West

How much does pressure washing cost in Key West?

Pressure washing in Key West is priced based on square footage, surface type, and the scope of work — so every quote is customized to your property. Homes in the Florida Keys accumulate marine algae, salt film, and mold faster than inland properties, which affects the time and equipment required. The best way to get an accurate price is a free on-site estimate. Contact Under The Sun Property Care at (786) 933-0510 to schedule yours.

How often should I pressure wash my home in the Florida Keys?

Most Key West homeowners benefit from pressure washing every 6–12 months. The combination of high humidity, salt air, and tropical rainfall accelerates mold, algae, and mildew growth significantly faster than inland Florida. Properties near the water, vacation rentals, and homes with stucco or concrete surfaces may need cleaning every 3–6 months. A seasonal schedule — once before tourist season and once after hurricane season — works well for most properties.

What's the difference between pressure washing and soft washing?

Pressure washing uses high-pressure water (2,000–4,000 PSI) to blast away dirt, mold, and debris from hard surfaces like concrete, brick, and pavers. Soft washing uses low pressure (under 500 PSI) combined with biodegradable cleaning solutions to safely clean delicate surfaces like wood siding, stucco, painted surfaces, and roofs. In Key West, many historic homes and wood-frame properties require soft washing. Under The Sun Property Care offers both and will recommend the right method for each surface.

Can pressure washing damage my Key West home's wood siding?

Yes — improper pressure washing can strip paint, gouge wood, and drive water behind siding. That's why we assess every surface before choosing equipment and pressure settings. Wood-frame and historic homes in Old Town Key West are typically treated with soft washing rather than high-pressure methods. When in doubt, we default to the lower-pressure method.
