A deck restoration in Charleston should fix what the weather broke, not just paint over it. We repair loose and soft boards, replace rusted fasteners, strip failing stain, wash off mildew and gray wood fibers, sand the surface smooth and finish with a penetrating stain chosen for how much sun and salt your deck gets.
Choose the right level of restoration
A sound deck with faded color needs only cleaning and a fresh coat of stain and sealer. A gray, rough or peeling deck needs full deck refinishing. If the boards themselves are worn out but the frame is solid, deck resurfacing puts new pine or composite on top. We also restore piazza and porch floors and private docks. Compare prices in the 2026 deck restoration cost guide.

Most restorations on a 400 square foot deck cost about $1,000 to $1,800 for cleaning and staining, and about $1,400 to $2,800 for a full strip, sand and refinish, before any board or railing repairs. Every estimate is written and free.
How long does a deck restoration take?
Most decks take two to four days, including drying time between cleaning and staining. Humidity and rain can add a day or two.
How often should a deck be stained in Charleston?
Every two to three years for most decks with semi-transparent stain. Decks in full sun or near the ocean may need a maintenance coat sooner.
What is the best stain for a Charleston deck?
For most pine decks, a penetrating oil or hybrid semi-transparent stain with strong UV protection and mildewcide. It soaks in instead of peeling and can be re-coated without stripping.
