What this covers
A deck stain protects wood from water and sun. The job starts with a cleaner to remove dirt, mildew and old finish, a brightener to open the grain, repairs to any split or soft boards, and light sanding. Then a penetrating stain or sealer is applied in dry weather, brushed into the grain and back-wiped so it does not pool. Railings and stairs are done the same way.
When to call
- Gray, faded or water-absorbing boards.
- An old finish that is peeling or flaking.
- A new deck that has weathered long enough to take a finish.

Questions people ask
Stain or paint?
Penetrating stains soak in and wear away gradually without peeling, which makes them easier to maintain on a deck. Paint and solid stains form a film that can peel on horizontal boards.
How often does a deck need staining?
It depends on sun, weather and the product. When water stops beading on the boards, it is time.
Can a new deck be stained right away?
Pressure-treated wood needs to dry out first, often a few months. Cedar and redwood can usually be finished sooner. The company tests the wood for readiness.
