Staining and sealing protect a sound deck from the two things that age it fastest in Charleston: UV and moisture. We clean and brighten the wood, let it dry to the right moisture level, then apply a penetrating sealer or semi-transparent, semi-solid or solid stain matched to your sun exposure and the look you want.
This service is part of our our Charleston deck restoration options. Homeowners who need it often ask about low-pressure deck cleaning, resurfacing over the existing frame or piazza and porch floor restoration at the same time, so we price and schedule them together.
Choosing a finish
- Clear and toned sealers: show the most grain, need re-coating about every year in full sun
- Semi-transparent stain: the most popular choice, shows grain and lasts about two to three years
- Semi-solid stain: hides mismatched boards while some texture shows through
- Solid stain: hides the most, but needs care on horizontal surfaces to avoid peeling
Timing in Charleston
Spring and fall are ideal. We stain when the wood is dry, rain is not expected for 24 hours, and the boards are out of direct midday sun. If the old finish is failing, start with deck refinishing instead.
Typical cost
Cleaning plus one or two coats typically runs $2.50 to $4.50 per square foot, or about $1,000 to $1,800 for a 400 square foot deck.

Frequently asked questions
How often should I stain my deck in Charleston?
Most decks with semi-transparent stain need a maintenance coat every two to three years. Decks in full sun or near the ocean may need it sooner, and shaded decks can go longer.
How long before I can use my deck after staining?
Light foot traffic is usually fine after 24 to 48 hours. Wait 48 to 72 hours before putting furniture and rugs back.
Should a new pressure-treated deck be stained right away?
No. New pressure-treated wood is wet. It usually needs a few weeks to a few months to dry before it will absorb stain properly. We test the moisture first.
