Fence staining lasts 3–5 years on vertical surfaces in Colorado because boards shed water instead of pooling it. The prep standards are the same as decks. The most common mistake is staining too soon after a new fence goes in.
New fence timing
New lumber carries mill moisture — and in some cases the treatment process adds more. Staining above 15% moisture content traps water beneath the finish and causes peeling within a season. We check moisture with a pin-type meter before every job. A homeowner in Longmont had a new cedar fence installed in May and wanted it stained immediately. We tested the moisture content — 22%, which was too high. We recommended waiting six weeks. They did. The stain penetrated evenly, and two years later the fence still holds colour without any peeling.
For cedar in Colorado's dry summer climate, the wait is typically 3–5 weeks after install. Pressure-treated wood usually needs 6–12 weeks. The calendar date doesn't matter — the meter reading does.
Penetrating stain vs film-forming
A penetrating oil-based stain absorbs into the wood cells. There's no film sitting on the surface. When it wears out, the wood gradually loses colour and water-repellency — but it doesn't peel. You clean, brighten, and recoat. A film-forming product — whether it's called stain, coating, or solid colour — sits on the surface like paint. On fences, these products eventually crack at the edges and grain lines. When they do, stripping is the only path before the fence can be properly restained. Every time you use a film-forming product, you're choosing harder future maintenance.
One side or both
We assess both faces of the fence during the estimate. If both are accessible and exposed to weather, treating both sides protects the wood fully. One-sided staining is the right call when the back face is sheltered, against a structure, or in deep shade — in those cases, the exposed face is taking the damage and that's where the product needs to go.
Before you book
If your fence boards are soft, spongy, or rotting at the base, staining isn't the answer. Stain on rotten wood makes rotten wood look better briefly — it doesn't add structural life. We'll identify soft boards during the estimate and quote repair or replacement separately before any stain work happens.
