Home Exterior Washing in St. Augustine, FL

St. Augustine's coastal climate puts mold, mildew, and salt film on exterior surfaces faster than inland Florida. Professional house washing removes what has built up and protects the paint, stucco, and siding underneath.

What Florida's Climate Does to Exterior Surfaces

Why St. Augustine Homes Need Regular Exterior Cleaning

The combination of heat, humidity, salt air, and year-round moisture that defines St. Augustine's coastal environment creates near-perfect conditions for mold, mildew, algae, and oxidation on exterior surfaces. Homes in the Historic District develop mold along shaded walls and north-facing elevations. Properties on Anastasia Island and Vilano Beach accumulate salt film that dulls paint and accelerates corrosion in any metal fasteners or trim. St. Augustine Beach homes often show streaking within a few months of a fresh paint job because the conditions never let surfaces fully dry.

None of this is a reflection of poor maintenance. It is simply the reality of living in a coastal Florida environment. What matters is how regularly the buildup is addressed and whether the cleaning method matches the surface type, because the wrong approach (too much pressure on stucco, the wrong chemistry on painted brick) creates damage that costs far more to fix than the cleaning was worth.

Our Approach

Surface-Matched Cleaning for Every Exterior Type

A single pressure washing method applied to every surface type is how cleaning jobs cause damage. Stucco, which is the most common exterior surface in St. Augustine's newer construction, is porous and painted. It requires a soft washing approach (low pressure with surfactant chemistry) rather than high-pressure stripping. Vinyl siding can handle moderate pressure but is prone to water intrusion behind panels if water is directed upward. Hardie board holds paint well but the factory finish requires gentler treatment than bare concrete. Brick needs pressure to lift grime but painted brick needs a much lighter touch to protect the paint film.

We assess the surface before we start and set pressure, nozzle, and chemistry for what is actually in front of us. The result is a thorough clean that does not create a future repair bill.

  • Pre-treatment rinse of landscaping and surrounding hardscape
  • Application method selected to match the specific exterior surface
  • Full exterior coverage including soffits, eaves, and window frames
  • Special attention to north-facing and shaded elevations with heavier mold buildup
  • Low-pressure rinse that does not force water behind siding or into wall cavities
  • Post-wash walk-around inspection before we leave

Neighborhoods We Serve

House Washing Across St. Augustine and St. Johns County

We clean homes throughout St. Augustine and St. Johns County, including the Historic District, Anastasia Island, Vilano Beach, St. Augustine Beach, Palencia, Nocatee, and surrounding neighborhoods. Coastal properties (those on Vilano Beach, along A1A, and on the barrier island) typically show the most dramatic transformation because salt film and airborne moisture have been building for months between cleanings.

If you are in a neighborhood with an active HOA, we are familiar with the exterior maintenance requirements common to St. Johns County associations and can document the work for your records. Many of our house washing jobs are prompted by HOA compliance notices, and we are able to respond quickly to get properties back in compliance.

Honest Fit Check

Is House Washing the Right Service for Your Home?

House washing solves a specific set of problems. Here is what it does and does not cover.

A good fit if

  • Green or black growth is showing on stucco, vinyl, or painted siding
  • You are on the water and salt film has dulled the whole exterior
  • Your HOA has flagged the appearance of the home itself, not just the drive
  • You are painting soon and need a clean surface for the coating to bond to

Not the right fit if

  • The paint is already chalking or peeling, because washing will take more of it off
  • You need the siding repaired or replaced, which is a siding contractor's work
  • You want interior windows cleaned, which we do not do
  • The home has damaged or missing siding that would let water behind the wall

House washing is quoted on square footage, storey count, siding material, and how heavy the growth is. Starting prices are on the pricing page.

The Process

How a House Washing Runs

Whole-home washing touches more surface types than any other job we do, so it is sequenced around the material, not the elevation.

Send Us Your Siding Details

Siding material, how many storeys, and where the growth is worst. North-facing walls and anything under a tree canopy are usually the first to go green.

Your Openings and Beds Get Covered

Your windows and doors get checked, exterior outlets and fixtures get covered, and the beds along the wall get pre-wet so runoff dilutes instead of concentrating at the roots.

Soft Wash the Walls, Top Down

A low-pressure solution goes on from the top down, dwells, and lifts the mildew and salt film out of your surface texture. Stucco and painted surfaces never see high pressure.

Rinse and Check the Detail Work

Your soffits, fascia, window frames, and light fixtures get checked one at a time, because those are the spots a fast job skips and the ones you notice from your own driveway.

Real Job, Real Result

What a House Wash Takes Off Florida Siding

Two St. Johns County homes, each photographed before and after a soft wash. The grey cast on the siding is biological growth and salt film sitting in the surface texture, which is why it comes back off with chemistry and low pressure instead of force.

The shaded elevation always carries the heaviest growth. It gets the longest dwell time rather than the highest pressure.

FAQ

Common Questions from St. Augustine homeowners asking about house washing

We clean all residential exterior surface types common in St. Augustine: stucco, vinyl, fiber cement (Hardie board), painted brick, wood siding, and EIFS (synthetic stucco). Each surface requires different pressure levels and chemistry. Stucco and painted surfaces receive soft washing. Vinyl and Hardie board are cleaned at low-to-medium pressure with appropriate surfactants.

Annual house washing is a reasonable baseline for most St. Augustine homes. Homes within a few miles of the coast, particularly in Vilano Beach, Anastasia Island, and St. Augustine Beach, typically benefit from washing every six to nine months because salt film and airborne moisture accelerate mold and mildew growth significantly.

We pre-wet all plants, shrubs, and lawn areas near the work zone before applying any cleaning solution, and we rinse them thoroughly after the job is complete. For particularly sensitive plantings, we can modify our approach or shield them during treatment. We have cleaned properties with extensive landscaping throughout St. Johns County without landscape damage.

Yes. We direct water away from windows and entry points and use lower pressure on any surface near penetrations. Soft washing inherently uses lower pressure than standard power washing, which reduces the risk of water intrusion significantly. If you have known gaps around windows or doors, let us know during the estimate and we will adjust our technique accordingly.

Cost depends on square footage, story count, surface type, and the degree of mold or algae buildup. See our pricing page for starting prices, or contact us for a free on-site or photo estimate specific to your property.

Most St. Augustine homes stay visibly clean for six months to a year, depending on tree coverage, proximity to the coast, and shade. Coastal properties and heavily shaded lots tend to show new growth sooner because salt film and moisture accelerate regrowth.

Combine Services and Save a Trip

Most homeowners who schedule a house washing also benefit from combining it with driveway cleaning, roof soft washing, or gutter cleaning. Scheduling multiple services in a single visit saves time and often reduces the total cost compared to separate appointments.
