A fence is exposed to weather 24/7, so a little care goes a long way. The goal is to keep water out and movement under control.
Wood fences
- Clean yearly to remove the algae and gray that ages wood.
- Seal or stain every 2–3 years — water getting into the grain is what causes rot and warping.
- Keep sprinklers from spraying it and trim back plants leaning on it.
Vinyl & aluminum fences
Low maintenance, but they still get a green algae film on the shaded side. A gentle wash once a year keeps them bright. Check that posts are still solid after big storms.
Catch problems early
A wobbly post or a small rot spot is cheap to fix now and expensive to ignore. Most of a fence's lifespan comes down to dealing with water and movement before they spread.
