There's no single number, but there is a reliable test. Spray a few seconds of water on a board and watch what it does.
- Beads up and rolls off: the finish is still working. Leave it alone.
- Soaks in and darkens the wood: the sealer has worn out. Time to clean and recoat.
- Some boards bead, some soak: the sun-facing runs are done first — that's normal, and it's why fences often get done in stages.
The rough schedule around here
Most Central Texas fences want a wash every one to two years, and a fresh penetrating stain every two to four. West-facing runs, unshaded yards and full-sun properties sit at the short end; heavily shaded fences usually go longer between coats but grow mildew faster, which is a different problem.
Why waiting costs more
A fence that's recoated on schedule just needs a wash and a coat. A fence that's gone fully gray and dry needs more prep to get back to sound wood — and if it's left long enough, boards start to cup, crack and rot, at which point no finish will save them. Re-coating is cheap. Rebuilding a fence line is not.
What we do about it
We clean, brighten and dry the wood, then seal it with a professional-grade penetrating stain, and we'll tell you honestly if a section isn't worth coating yet. If you're not sure where your fence stands, send a couple of photos with a quote request — the answer is usually obvious from the wood color and how it takes water.
