Fix the Weak Spots. Reinforce the Frame.

Deck Repair & Structural Reinforcement in South Carolina

Don’t Replace It — Restore It

We Repair What Time, Moisture & Weather Break Down

Not every old or damaged deck needs to be replaced. Often, the framing is still good — it’s just the surface, fasteners, or specific sections that need help. We carefully inspect your deck to identify weak spots, water damage, code issues, or unsafe features. Then we repair what matters and reinforce what’s worth saving — giving you more years of safe, enjoyable outdoor space at a fraction of the cost of a full rebuild.

From Wobbling Stairs to Rotten Joists

What’s Included in Our Deck Repair Services

We handle everything from surface board swaps to full structural reinforcement. That includes new footings, joist sistering, ledger board replacement, stair rebuilds, railing anchoring, and hardware upgrades. Every repair is made with pressure-treated lumber, coated fasteners, and framing techniques that meet or exceed South Carolina building code. We also prep repaired surfaces for new stain or decking, so your upgrade looks seamless.

Safety Isn’t Optional — It’s the Whole Point

We Bring Old Decks Back Up to Code

Loose railings. Unstable stairs. Soft spots underfoot. These aren’t just annoying — they’re dangerous. Our team performs full safety checks and brings your deck up to current South Carolina building code. That includes correcting joist spacing, replacing undersized beams, anchoring posts, and ensuring handrails meet height and strength standards. We don’t just patch over problems — we fix them at the source.

Local Weather Is Tough on Wood

We Repair What the Heat, Rain & Humidity Have Damaged

South Carolina’s climate is tough on decks. From year-round humidity to hurricane-season rainfall, untreated or poorly built structures break down fast. We replace rotted posts, upgrade fasteners, add ventilation, and reframe areas where water or pests have caused hidden damage. We know how to build and repair decks for low country, coastal, and inland weather — and we never cut corners.

Better Materials. Smarter Fasteners. Safer Builds.

Modern Repairs for Old-School Decks

Many older decks were built before modern standards — with nails instead of screws, no flashing, or wood not rated for ground contact. We bring those decks into the 21st century with moisture-blocking tape, Simpson brackets, hurricane ties, and sealed fasteners. Whether it’s a 15-year-old deck or just one poorly built last summer, we’ll strengthen it properly so you can use it confidently.

Deck Repair FAQs

What South Carolina Homeowners Ask Most

Here are answers to the most common questions about deck repair and reinforcement — especially for aging or weather-damaged structures.

Can you repair just part of a deck?

Yes. We often replace only damaged sections, preserving the parts of your deck that are still structurally sound.

How do I know if my deck is safe?

If your deck wobbles, leans, or has soft spots — or if it’s over 10 years old — it’s time for an inspection.

Do repairs need permits in South Carolina?

Sometimes. We’ll determine what’s required and handle permitting when needed — especially for framing or stair repairs.

Can you upgrade my deck’s stairs and railings too?

Absolutely. Most repairs include safety features like stronger railings, better step alignment, and updated access points.
