Fall is the single best time of year to pressure wash your Florida home — and most homeowners don't take advantage of it. The summer rainy season ends in late September, leaving behind months of accumulated algae, mold, and organic growth on every exterior surface. Temperatures drop into the comfortable range for outdoor work. And the holiday season is approaching, when your home's exterior will be seen by more guests, neighbors, and visitors than at any other time of year.

If you're going to do one round of professional exterior cleaning per year, fall is the time to do it. Here's a complete checklist of every surface that benefits from attention before the holidays arrive.

1. House Exterior (Soft Wash)

Your home's exterior walls accumulate more biological growth over the summer than any other time of year. Florida's rainy season — June through September — creates the perfect conditions for mold, mildew, and algae to colonize stucco, painted surfaces, and siding. By October, most Florida homes have visible dark streaking, green patches near the roofline, or a general gray-brown discoloration that wasn't there in the spring.

What to look for: Dark streaking running down from the roofline, green or black patches near the foundation or in shaded areas, general discoloration of stucco or painted surfaces.

Method: Soft washing — low-pressure application of professional cleaning solutions. Never high-pressure washing on stucco or painted surfaces.

Timing: Schedule in October or November, after the rainy season ends and before holiday gatherings begin.

2. Roof

Roof algae spreads aggressively during Florida's rainy season. The dark black and gray streaks that appear on asphalt shingles and tile roofs are active biological growth — Gloeocapsa magma — that feeds on roofing material and spreads with every rain event. Fall is the ideal time to address it before another year of growth causes additional damage.

What to look for: Dark streaking from ridge to eave, green or brown moss patches on north-facing sections, discoloration in roof valleys.

Method: Soft washing only — ARMA guidelines prohibit pressure washing on asphalt shingles. Tile roofs also require low-pressure technique to avoid cracking tiles and damaging underlayment.

Timing: October through December — cooler temperatures and lower humidity make fall ideal for roof cleaning throughout Northeast and Central Florida.

3. Driveway and Walkways

Your driveway is the first surface guests see when they arrive for holiday gatherings. Summer rain, vehicle traffic, and organic debris leave driveways stained with algae, tire marks, oil, and tannin discoloration. A clean driveway makes an immediate positive impression and removes the slippery algae growth that creates a liability risk.

What to look for: Dark green or black algae growth, oil stains, tire marks, tannin staining from oak leaves, efflorescence (white mineral deposits) on pavers.

Method: Surface cleaner at appropriate pressure for the surface type — higher for concrete, lower for pavers to protect joint sand.

Timing: October or November — after the last heavy rains of the season and before holiday guests arrive.

4. Patio, Pool Deck, and Outdoor Living Areas

Outdoor living spaces in Florida get heavy use year-round, and they show it. Pool decks accumulate algae and calcium deposits; paver patios develop mold and tannin staining; concrete patios collect organic debris and biological growth. Fall cleaning restores these spaces for the cooler months when outdoor entertaining peaks in Florida.

What to look for: Algae and mold on pool deck surfaces, calcium deposits around pool edges, tannin staining on paver patios, general discoloration of concrete outdoor areas.

Method: Surface cleaner for large flat areas; pressure wand for edges and detail areas; calcium remover pre-treatment for pool deck deposits.

Timing: October — before the peak outdoor entertaining season of November through March.

5. Fence

Fences are often the most neglected exterior surface on a Florida property. Vinyl fences develop green algae and mold that makes them look gray and dingy; wood fences accumulate mold, mildew, and tannin staining; aluminum fences develop oxidation and organic growth. A clean fence dramatically improves the overall appearance of your property.

What to look for: Green or black algae on vinyl fencing, dark mold staining on wood fencing, general discoloration of any fence material.

Method: Low-to-medium pressure with appropriate cleaning solution for the fence material — lower for vinyl to avoid warping, medium for wood.

Timing: Fall — before the fence becomes a backdrop for holiday decorations and outdoor gatherings.

6. Gutters and Fascia

Gutters and fascia accumulate mold, mildew, and organic staining throughout the rainy season. Dark streaking on the exterior of gutters — called "tiger striping" — is caused by electrostatic bonding of organic particles to the gutter surface. Fall cleaning removes this staining and prepares gutters for the leaf drop of late fall.

What to look for: Dark vertical streaking on the exterior of gutters, mold and mildew on fascia boards, general discoloration of soffit and fascia.

Method: Low-pressure soft washing with appropriate cleaning solution — high pressure can dent aluminum gutters and damage fascia paint.

Timing: October — after the rainy season and before significant leaf accumulation.

7. Screen Enclosures

Florida screen enclosures — pool cages, lanais, and porch enclosures — accumulate algae, mold, and organic debris on both the frame and the screen material. A dirty screen enclosure is immediately visible from inside and outside the home, and the biological growth on screen material reduces light transmission and airflow.

What to look for: Green or black algae on screen frame and screen material, mold on the enclosure floor, general discoloration of the frame.

Method: Low-pressure soft washing — high pressure damages screen material and can bend aluminum frame members.

Timing: Fall — before the peak season for outdoor living in Florida's cooler months.

Scheduling Your Fall Cleaning in Northeast and Central Florida
