Deck Repair & Rot Restoration in New Hampshire

Don’t ignore a wobble. A deck that flexes, bounces, or leans is telling you something about the structure underneath — and in New Hampshire’s freeze-thaw climate, small problems become structural failures fast. Chippy’s inspects, repairs, and resurfaces decks across Central NH. We fix what’s broken, we never cover up rot, and we tell you honestly when repair is the smarter money and when it isn’t.

Structural Deck Repairs That Keep Your Family Safe

The dangerous problems are the ones you can’t see from a lawn chair: loose or under-bolted ledger boards (the #1 cause of deck collapses), rotted rim joists, failing stair stringers, and railings that give when you lean on them.

We reinforce ledger connections, sister or replace compromised joists, rebuild stair stringers with proper spacing, and secure railings to code. These are the details that keep your deck standing.

Explore our full list of deck services to see how we make your outdoor space safe again.

Rotted Deck Board & Frame Repair

Soft spots, cupped boards, and splintering surfaces don’t always mean the deck is done. If the frame below is sound, we replace the rotted decking and damaged framing members and give the deck years more life. And if we strip the boards and find hidden damage — a rotted rim joist, a failed post — we stop and show you immediately, price the fix clearly, and get your approval before moving forward. We never cover up rot.

Resurface Your Pressure-Treated Deck with Composite

This is one of the most popular projects we do: the frame of a well-built pressure-treated deck often outlives its surface by decades. If your joists and footings are solid, we strip the old wood decking and railings and resurface the entire deck with modern composite — new boards, new railings, hidden fasteners.

You get what looks and feels like a brand-new maintenance-free deck for a fraction of the cost of a full rebuild, because the structure you already paid for keeps working for you. We inspect the frame first and only recommend resurfacing when it will actually last.

Repair or Rebuild? An Honest Assessment

If the frame and footings are solid, repair or resurfacing saves you real money. If the frame has significant rot, the footings are heaving, or the structure was never built to modern code, a rebuild is the safer, longer-lasting investment — and we’ll show you exactly why, with photos of your own deck, not a sales pitch. Either way, the free assessment costs you nothing.
