A quality exterior paint job should last 8-10 years in Nashville's climate. But without basic maintenance, that number drops to 5-6 years. The good news: keeping your paint looking fresh requires just a few hours of attention each year.
Annual Power Wash (or Garden Hose Rinse)
Nashville's humidity breeds mildew, especially on north-facing walls and under eaves. A gentle power wash once a year — or even a garden hose with a car-wash brush — removes the green and gray film that breaks down paint over time. Use a mildew-killing detergent on stubborn spots.
Inspect and Caulk
Walk around your home once a year and check the caulk around windows, doors, and trim joints. Old caulk shrinks and cracks, letting moisture behind the paint film. A $5 tube of exterior caulk can prevent hundreds of dollars in paint failure.
Touch Up Immediately
When you spot a chip, scratch, or peeling spot, touch it up right away. Exposed wood absorbs moisture, and the damage spreads quickly. Keep a small can of your exterior paint color on hand for quick fixes.
Trim Vegetation
Bushes, vines, and tree branches that touch your siding trap moisture against the surface. Keep at least 12 inches of clearance between vegetation and painted surfaces. This also improves airflow and reduces mildew growth.
Watch Your Sprinklers
Sprinkler heads that spray directly onto painted siding cause premature failure. Check your irrigation system and redirect any heads that hit the house.
