Frequently Asked Questions
How often does a Florida home exterior need repainting?
In Florida's harsh UV, quality exterior paint lasts 7–10 years on wood surfaces and 10–15 years on stucco with proper application. Lower-quality paints or poor surface prep can require repainting every 4–6 years. Using SW Emerald or Duration with proper primer extends paint life significantly.
What is the best exterior paint color for Florida?
Lighter colors (whites, light grays, light tans) absorb less heat in Florida sun and stay cooler. Dark exterior colors on Florida homes increase cooling costs. Most Florida HOAs require light exterior colors as well. Energy Star certified cool roof coatings are available for maximum heat rejection.
