How Often to Paint House Exterior in Florida

You've noticed your neighbor's house still looks freshly painted while yours is showing its age - even though you both painted around the same time. What gives?

The difference usually comes down to factors most homeowners don't think about until it's too late: prep quality, coating choice, and whether your painter understood Florida's unique climate demands. A properly done paint job can outlast a rushed one by five or more years.

Realistic Lifespan by Siding Type

Most Florida homes need exterior repainting every five to seven years. That's significantly shorter than the seven to ten years northern states get from the same paint. Florida's intense UV, high humidity, salt air, and daily temperature swings create one of the most demanding environments for exterior coatings in the country.

Stucco homes - the most common in Sarasota - typically get five to seven years from standard acrylic latex. Elastomeric coatings designed for stucco can push that to seven to ten years. Wood siding lasts only three to five years with regular paint and five to seven with oil-modified alkyds. Fiber cement like Hardie board is the durability champion, lasting seven to ten years with field-applied paint and ten to fifteen with factory finishes. Vinyl siding usually doesn't need paint, but if painted, expect five to seven years.

For coastal homes on Siesta Key, Longboat Key, or within a mile of the Gulf, subtract one to two years from all these numbers. Salt air accelerates paint breakdown significantly.

Why Florida Chews Through Paint

Florida receives 230+ sunny days annually with intense UV radiation. That UV breaks down paint binders - the adhesive that holds pigments to surfaces - faster than anywhere else in the country. South and west-facing walls take the worst of it, fading 20-30% faster than shaded surfaces.

Then there's humidity cycling. Paint expands and contracts with moisture changes. Florida's 85-95% summer humidity followed by 50-60% winter humidity stresses coatings repeatedly, year after year.

Coastal homes face constant salt exposure on top of everything else. Salt is hygroscopic, meaning it attracts moisture and keeps surfaces damp longer. That accelerates every other degradation process.

High humidity also promotes biological growth. Without mildewcides, paint becomes a breeding ground for mold that discolors and degrades the coating.

Warning Signs Your Home Needs Repainting

Don't wait for complete failure. Watch for these warning signs that indicate your paint is no longer protecting your home.

Chalking is the earliest warning. Run your hand across the painted surface. If white or colored residue comes off on your fingers, the paint binders have broken down. This leaves surfaces unprotected and indicates repainting is needed within six to twelve months.

Fading shows next. Compare hidden areas under eaves or behind shutters to exposed surfaces. Significant color difference means UV has degraded the pigments. While fading alone is cosmetic, it typically accompanies binder breakdown.

Peeling or flaking is an emergency. Any paint lifting from the surface exposes substrate to moisture, leading to rot on wood, efflorescence on stucco, or corrosion on metal. Address immediately.

Cracking allows moisture penetration. Hairline cracks are concerning. Alligator cracking - that pattern resembling reptile skin - indicates complete coating failure requiring full removal and repainting.

Mold and mildew show as black, green, or gray patches. While sometimes cleanable, extensive mold usually means the mildewcide has failed and repainting with proper additives is necessary.

Bubbling or blistering means moisture is trapped under the paint film. This requires identifying and fixing the moisture source before repainting, or the problem will recur.

What Shortens and Extends Paint Life

Poor surface preparation guarantees early failure. Skipping pressure washing, not addressing repairs, or painting over chalking paint means you're throwing money away. Prep work accounts for 80% of paint job success.

Low-quality paint may cost 50% less but fails in half the time. Per-year cost is actually higher with cheap coatings.

Direct sun exposure hits south and west walls hardest. These surfaces may need touchups two to three years before north and east walls.

Premium coatings like Sherwin-Williams Duration and Emerald contain better binders and UV blockers. They cost 30-40% more but last 40-60% longer.

Proper primer creates adhesion between substrate and paint. Skipping primer saves $200-400 but costs $2,000+ in early repainting.

Annual pressure washing removes mold, salt, and debris before they damage coatings. A $200-300 cleaning extends paint life by years.

Prompt repairs make a difference too. Fixing cracks, caulk failures, and small peels immediately prevents moisture damage that requires full repainting.

Get Your Home Assessed

If your Sarasota home shows any warning signs or is approaching the five to seven year mark, schedule a professional inspection. We'll assess your current coating condition and recommend whether touchups, cleaning, or full repainting makes sense.
