The Florida Exterior Problem
Your Property Exterior Has a Florida Problem
St. Augustine sits in a near-perfect storm of exterior cleaning challenges. The salt air off the Atlantic accelerates mold and corrosion on siding, fences, and metal surfaces. Summer humidity keeps algae growing year-round on driveways, patios, and roof shingles. Between HOA compliance requirements and the tourist-driven expectation of clean, well-maintained properties, St. Augustine homeowners and business owners face real pressure to keep up.
If you have noticed black streaks on your roof, green slime creeping across your driveway, or a hazy film on your home's exterior, those are not just cosmetic issues. They are early signs of surface degradation that, left untreated, shortens the lifespan of your roofing, siding, and concrete.
- Black algae streaks across roof shingles that will not wash off with rain
- Mold and mildew returning weeks after you try cleaning it yourself
- HOA violation notices over dirty driveways or algae-covered siding
- Oil stains, tire marks, and rust that standard cleaners cannot reach
- Salt residue and corrosion building up on fences, gutters, and soffits
- Algae-slicked walkways and pool decks that become slip hazards
- Storefronts and parking areas that put off customers before they walk in
- A listing photo shoot coming up and an exterior that photographs grey

Why Cannon
What Separates Cannon Exterior Cleaning
There are dozens of pressure washers in St. Augustine. Here is what makes a concrete difference in the quality and safety of the work we deliver.
Surface-Specific Methods
There is no single pressure setting that suits every job. Concrete gets high pressure. Shingles get low-pressure soft washing. Stucco gets a gentle solution rinse. The wrong approach damages your property, so your surfaces set the settings.
Commercial-Grade Equipment
Consumer-grade pressure washers top out around 2,000 PSI. Commercial equipment delivers up to 4,000 PSI with heated water for oil and grease, so your heavily soiled surfaces actually get clean instead of just getting wet.
Licensed and Fully Insured
Every job is covered. If something goes wrong during cleaning, your property is protected and you are not left dealing with an uninsured crew. Liability coverage appropriate to residential and commercial work is in place on every job.
Deep Local Knowledge
Five years on St. Augustine properties surfaces things a general contractor will not know about yours: how salt air behaves on Vilano Beach stucco, which algae strains dominate Anastasia Island shingles, and how Historic District coquina stone needs a different approach than modern vinyl siding.
Flexible Scheduling
Commercial properties get early mornings, evenings, and weekends so your trading hours stay clear. Residential jobs are booked around your availability.
HOA Compliance Ready
Many St. Augustine neighborhoods have strict exterior maintenance standards. Your community's compliance requirements are already familiar, and you get documentation of completed work whenever the board asks for it.

What Property Owners Are Saying
We publish reviews with a real name, a real neighbourhood, and permission to use them, which means this section stays empty until those come in rather than filling it with copy nobody said. Ask for references and you will be put in touch with recent customers directly.
About Cannon
St. Augustine's Locally Operated Exterior Cleaning Crew
Cannon Exterior Cleaning was built around one idea: St. Augustine properties deserve a cleaning service that understands coastal Florida. The salt air, the subtropical humidity, the Historic District's unique coquina and stucco surfaces, and the HOA-heavy neighborhoods scattered from Ponte Vedra down to Anastasia Island all require a different level of attention than a generalist crew can provide.
Jake Cannon founded the business with five years of hands-on experience learning exactly how Florida's coastal environment ages a property's exterior and what it takes to reverse it. Homeowners and commercial property managers across St. Augustine and St. Johns County are both served.

We Clean St. Augustine Businesses Too

FAQ
Common Questions from St. Augustine homeowners and business owners
Pricing depends on the surface type, square footage, and level of buildup. Residential jobs are priced by property and surface condition, and commercial properties are quoted on a per-job basis. Visit our pricing page for starting prices by service, or contact us for a free, no-obligation estimate specific to your property.
Pressure washing uses high-force water to blast away heavy buildup from hard surfaces like concrete and brick. Soft washing uses lower pressure combined with professional cleaning solutions to safely treat delicate surfaces like roof shingles, stucco, and wood siding where high pressure would cause damage. Each surface on your property gets the method that suits it.
Because of Florida's humidity, salt air, and year-round heat, most St. Augustine homes benefit from professional exterior cleaning once a year. Properties near the coast or with heavy tree coverage may need cleaning every six to nine months to stay ahead of algae, mold, and mildew growth.
Yes. Cleaning your home exterior before hurricane season is actually good preparation, removing debris, mold, and organic buildup that can trap moisture and accelerate storm damage. Your annual cleaning is best scheduled in spring, before the June-through-November storm window opens.
Yes. We serve properties throughout St. Augustine, St. Augustine Beach, Anastasia Island, Vilano Beach, Ponte Vedra, and the broader St. Johns County area. Salt air accelerates buildup on coastal properties, and our team understands how to address those specific conditions.
Black streaks on roofs are almost always Gloeocapsa magma, a type of algae. Roof soft washing, not high-pressure washing, is the correct treatment. Our low-pressure soft wash process uses a professional-grade algaecide solution that kills the algae at the root, removing streaks without voiding your roofing warranty or damaging shingles.
