Quality exterior paint on properly prepared surfaces lasts 7-10 years in Southwest Florida. Barrier-island properties with direct salt air exposure on Siesta Key, Longboat Key, and Casey Key may need recoating every 5-7 years. Cheap paint on poor preparation fails in as little as 2-3 years.
Three factors determine exterior paint longevity in Florida: surface preparation quality, product selection, and exposure severity. Preparation accounts for 60-70% of the equation -- pressure washing, scraping loose paint, repairing substrate damage, priming bare surfaces, and caulking gaps all extend coating life.
Salt air accelerates paint degradation by depositing corrosive chloride crystals on the paint film. Gulf-facing elevations degrade 30-40% faster than sheltered sides of the same home. Our barrier-island protocol adds extra primer coats on salt-facing walls and specifies coatings with enhanced salt-spray resistance.
Grove Street Painting's 10-year workmanship warranty reflects our confidence in the preparation and product systems we use. We document every surface, primer, and topcoat in your written proposal for long-term reference. Review our exterior painting process to understand how proper prep extends your coating's lifespan.
