Deck repair in Charleston usually starts with the same few problems: boards that went soft where water sits, railings that move when you lean on them, stairs with split treads, and joist hangers and nails that rusted in the salt air. We find every weak spot, fix the frame first, and leave you with a deck that is solid underfoot and ready to be refinished.
Repairs range from replacing a few rotted boards to rebuilding railings and stairs, and when the frame is too far gone, a full deck replacement. Not sure what you need? Start with a free deck safety inspection.

Repair, restore or replace?
If the frame is sound and less than about a quarter of the boards are bad, repair plus a full refinish is almost always the best value. If many joists are soft or the ledger was never flashed, we price a deck replacement next to the repair so you can compare honestly.

Small repairs such as a few boards and fasteners typically run $250 to $900. Railing sections run about $45 to $95 per linear foot and a new set of stairs about $900 to $2,500. Every price is written before work starts.
Frequently asked questions
How much does deck repair cost in Charleston?
Small repairs like replacing a few boards and resetting fasteners usually cost $250 to $900. Railing replacement runs about $45 to $95 per linear foot, and rebuilding a set of stairs about $900 to $2,500, depending on height and materials.
Can you repair my deck and then stain it?
Yes. Most of our restoration jobs start with repairs, then cleaning, sanding and staining, so the new boards and old boards end up with one even finish.
How do I know if my deck is still safe?
Warning signs include soft or spongy boards, a railing that moves, rust on hangers or bolts, gaps between the deck and the house, and posts sitting in water. A free deck inspection checks all of these.
