Soft Washing Services in Key West, FL

Under The Sun Property Care provides professional soft washing for homes, roofs, fences, and delicate exterior surfaces throughout Key West and the Lower Florida Keys. Soft washing uses low pressure (under 500 PSI) combined with biodegradable cleaning solutions to safely remove mold, algae, mildew, lichen, and salt deposits from surfaces that would be damaged by high-pressure washing. In Key West — where historic wood-frame homes, stucco exteriors, and painted concrete block are common — soft washing is often the right choice for exterior cleaning.

What We Soft Wash

Roofs

Roof cleaning is one of the most important soft washing applications in the Florida Keys. Black streaking and green growth on roofs is caused by Gloeocapsa Magma bacteria and algae — organisms that thrive in Key West's humidity and can degrade roofing materials over time if left untreated. High-pressure washing voids most roof warranties and damages shingles. Soft washing treats roof staining at the source with professional-grade solutions, without damaging the surface. Results typically last 2–4 times longer than pressure washing because the treatment kills the growth rather than just removing the visible layer.

Stucco Exteriors

Stucco is one of the most common exterior finishes in Key West, and it's highly porous — which means it holds moisture and allows mold and algae to take root deep in the surface. High-pressure washing can damage stucco, crack the finish, and force water behind the surface. Soft washing cleans stucco thoroughly without causing that damage, using solutions that penetrate and kill biological growth at depth.

Historic Wood-Frame Homes

Key West's Old Town is full of historic Conch-style homes with wood siding, painted wood trim, and delicate exterior finishes that have been on these structures for a century or more. Pressure washing these surfaces risks stripping paint, gouging wood grain, and forcing water into areas where it can cause rot. Soft washing cleans these surfaces safely, preserving paint and wood integrity while removing the salt film, mold, and mildew that accumulate in the coastal environment.

Painted Block & Concrete

Painted exterior walls on concrete block structures are common throughout Key West and the rest of Monroe County. High pressure can chip paint and damage the surface underneath. Soft washing cleans painted surfaces completely — removing biological growth and salt film — without risk to the paint or the masonry underneath.

Fences & Screens

Wood fences, vinyl fencing, aluminum pool cages, and screen enclosures require soft washing to clean safely. High pressure damages wood grain, strips paint, and can crack vinyl panels. Our low-pressure method cleans these surfaces thoroughly without causing surface damage.

Outdoor Furniture & Shade Structures

Patio furniture, pergolas, trellis structures, and awnings accumulate salt and biological growth in Key West's environment. Soft washing cleans these surfaces safely without damage to fabric, painted metal, or composite materials.

Soft Washing vs. Pressure Washing — Which Do You Need?

The right cleaning method depends on the surface. Hard surfaces like concrete driveways, pavers, and brick can typically handle high-pressure washing. Delicate, porous, or painted surfaces — roofs, stucco, wood, painted block — need soft washing to avoid damage.

At Under The Sun Property Care, we assess every surface before choosing our method. We don't default to high pressure just because it's faster. If soft washing is the right call for your home or a specific surface, that's what we use — and we explain why.

Many properties need both: a pressure wash for the driveway and pool deck, and soft washing for the home exterior and roof. We handle both in a single visit when needed.

Serving Key West and the Lower Florida Keys

We provide soft washing services throughout Key West — including Old Town, New Town, and the Truman Annex — and across the Lower Keys from Stock Island to Big Pine Key. For vacation rental properties and absentee owners, we coordinate with your property manager and document completed work.

Frequently Asked Questions — Soft Washing in Key West

Is soft washing safe for Key West's historic homes?

Yes — soft washing is the recommended method for historic Conch-style homes in Old Town Key West. High-pressure washing risks stripping paint, damaging wood, and forcing water into the structure. Our biodegradable cleaning solutions are safe for painted wood and delicate finishes, and our low-pressure delivery (under 500 PSI) won't damage a century-old wood frame. Call (786) 933-0510 if you're unsure whether your home needs soft washing or pressure washing — we'll assess it for free.

How long do soft washing results last?

On most surfaces, professional soft washing results last 1–3 years because the cleaning solutions kill biological growth at the root rather than just removing the visible surface layer. Roof cleaning results typically last 2–4 years on treated shingles. In Key West's particularly humid and salt-air-heavy environment, results at the shorter end of those ranges are more common — we'll give you a realistic estimate based on your property and its exposure. Call (786) 933-0510 to discuss.

Are the cleaning solutions used in soft washing safe for Key West's environment?

Yes — we use biodegradable, environmentally responsible cleaning solutions appropriate for use in coastal Florida. We take precautions to protect surrounding landscaping, outdoor plants, and drainage during every soft wash job. Key West's ecosystem is something we take seriously as a locally operated team.

How much does soft washing cost in Key West?

Soft washing pricing is based on the surface area being cleaned, the surface type, and the degree of biological growth present. Roof cleaning, home exterior washing, and fence washing are each priced differently. The best way to get an accurate quote is a free on-site estimate.
