Exterior Paint: lifespan, maintenance and replacement

Typical lifespan: 5–10 years (about 7 years).

Maintenance schedule

• Visual inspection for peeling/cracking — Annually (spring)
• Use siding-approved gentle cleaning; do not pressure-wash suspect lead paint — Every 1–2 years
• Touch up problem areas — As needed
• Caulk windows and trim — Every 2–3 years

Signs it needs replacing

• Widespread peeling or flaking
• Chalking (powdery residue on touch)
• Fading or discoloration
• Visible bare wood or siding
• Mildew growth that won't clean off

Tips

Before disturbing paint on pre-1978 homes, test for lead or assume it is present. Use a lead-safe qualified firm; never dry-scrape, power-sand or pressure-wash suspect lead paint. Follow coating and siding instructions.
