How to Maintain a Wood Fence
Quick Answer
Stain or seal a wood fence every 2-3 years, clean annually with a pressure washer, replace damaged boards promptly, and keep vegetation trimmed away from the fence line.
Annual Maintenance Checklist
A well-maintained wood fence can last 15-20 years. Follow this annual routine:
- Inspect for loose boards, leaning posts, and rot — especially at ground level
- Clean with a garden hose or light pressure wash (1,500-2,000 PSI max)
- Trim vegetation, vines, and tree branches away from the fence
- Repair damaged boards, tighten hardware, and re-secure loose rails
Staining and Sealing
Apply a quality wood stain or sealant every 2-3 years. This is the single most important thing you can do to extend your fence's life. Wait for a dry period with temperatures between 50-90°F. New pressure-treated wood should weather for 2-3 months before the first stain application.
Preventing Rot
The most common failure point is where posts meet the ground. Ensure posts are set in concrete (not bare soil) and that water drains away from the base. Keeping the bottom of fence boards 1-2 inches above ground prevents moisture wicking.
