Deck Staining & Sealing in Knoxville, TN — Cleaning, Repair and Refinishing for Wood Decks

Wood decks in East Tennessee spend much of the year damp. Stain and sealer are what keep water out of the boards, slow down mildew and stop the sun from turning the surface gray. We clean, repair, stain and seal wood decks across Knoxville and the surrounding counties.

Our Staining and Sealing Process

1. Inspect. We check boards, railings and stairs first, and tell you about anything loose or soft before finish goes on.

2. Clean. Dirt, mildew and failed finish are removed with a deck cleaner and a controlled wash. Too much pressure scars the wood, so we keep it low.

3. Dry. The wood must be dry before it will take finish. Depending on the weather this takes a day or more.

4. Repair. Popped fasteners are reset and damaged boards replaced so the finish goes on a sound surface. Larger problems are handled as a deck repair.

5. Apply. Stain or sealer is applied evenly to boards, railings and stairs, following the manufacturer instructions for temperature and drying time.

Choosing a Finish

Clear sealer keeps water out and lets the wood weather to its natural tone. It needs the most frequent recoating.

Semi-transparent stain adds color while showing the grain, and its pigment gives more protection from the sun. It is the most common choice for pressure-treated pine and cedar.

Solid stain covers the grain like paint and hides older, uneven boards. It protects well but shows wear in traffic paths.

How Often and When

There is no fixed schedule, because sun, shade and the product used all change the answer. The simple test is water: sprinkle some on the boards, and if it soaks in instead of beading, the deck is due. Most decks need attention every one to three years. The best time is a dry stretch of mild weather, which in Knoxville usually means spring or fall. Brand-new pressure-treated lumber needs time to dry out before its first coat.

Composite decking does not need staining at all, which is the main reason homeowners choose it. See composite vs. wood decking for the comparison, our wood deck builders page for new wood decks, and the deck maintenance guide for year-round care.

Frequently Asked Questions

How do I know if my deck needs to be resealed?

Sprinkle water on the boards. If it beads up, the finish is still working. If it soaks in within a few seconds, it is time to clean and reseal.

How long should a new pressure-treated deck dry before staining?

New pressure-treated lumber holds moisture from the treatment process and needs to dry before it will absorb finish. The time depends on the lumber and the weather, so we test the boards with water before applying anything.

Can you stain a deck that has gone gray?

Usually, yes. Gray boards are weathered on the surface but often sound underneath. Cleaning and brightening restores the color before stain goes on. Boards that are soft or split are replaced first.
