Practical advice on deck staining, fence maintenance, and wood care in Colorado. Real numbers. Honest takes on what works and what doesn't.
Deck staining in Colorado lasts 2–4 years on horizontal surfaces. Vertical fence boards hold stain longer — typically 3–5 years — because they don't pool water or take direct foot traffic. Here's what affects that number most.
Grey wood tone, water absorption instead of beading, cracking boards, visible mildew, and faded colour. If you see three of these before October, you're better off treating it now than waiting until spring.
Cedar stains better than pressure-treated lumber in nearly every case. The difference shows up in year two: cedar holds oil-based stain deeper into the grain, while PT wood's chemical treatment slows penetration and shortens the life of the finish.
New wood often has mill glaze — a compressed surface layer that blocks stain penetration. Staining too early traps moisture and causes peeling within months. Most new lumber needs 30–90 days to open up. We check moisture content before we touch it.
Staining over dirty or weathered wood traps contaminants under the finish. The stain may look fine for a few weeks, then peel in patches. A proper wash removes mould, dirt, and grey oxidation so the product bonds to clean wood — not to debris.
Fence staining costs in Boulder depend on three things: linear footage, wood condition, and whether repairs are needed first. Most residential privacy fences fall in a predictable range once you know what drives the price up or down.
