Almost none of them are on top. Boards can look sound while the frame holding them up is failing — and by November, when nobody’s using the deck, a compromised structure goes into a winter of snow load and freeze-thaw unnoticed. US ProPaint & Renovation repairs decks across Braintree, and here’s the check worth running before the first storm.

Take a flashlight and a screwdriver. Most of this happens underneath.
1. Probe for rot where water sits. Push the screwdriver into the wood at post bases where they meet grade, at the bottom of stair stringers, at the ends of joists, and under anything that’s been sitting on the deck for years — a planter, a grill mat, a hot tub. If the tip sinks in a quarter inch with light pressure, that’s rot, not weathering. Surface grey is cosmetic. Soft is structural.
2. Look at the ledger — the board bolting the deck to your house. This is the one that matters most. You want to see bolts or lag screws in a staggered pattern, not nails. You want flashing above it, turning water away from the house. What you don’t want: rust streaks running down from the fasteners, a visible gap between the ledger and the house, or any sign that water has been sitting behind it. Ledger failure is the single most common cause of deck collapse, and it’s usually invisible from the deck surface.
3. Push the railing — hard. Code expects a guard to take roughly a 200-pound push at the top without moving. Lean into it with your hip at a few points, especially at corners and where the railing meets the house. Any flex, any give at the post base, means the connection is going.
4. Check the joist hangers. Look for rust bleeding at the nail holes, hangers pulling away from the beam, or — surprisingly common — the wrong fasteners entirely. Deck screws and roofing nails are not hanger nails, and a hanger filled with the wrong fastener is holding far less than it looks like it is.
5. Bounce on it. Walk the middle of each span. Noticeable deflection or side-to-side sway means undersized joists, failed lateral bracing, or connections that have loosened. A sound deck feels like a floor.
6. Stairs and handrail. Loose or cracked stringers, treads that flex underfoot, a handrail you can rock. Stairs fail more often than deck surfaces do and hurt people more when they go.
If anything on that list turns up, stop using the deck until it’s looked at — particularly before snow sits on it.
There’s an age cohort we see more than any other, and there’s a specific reason for it.
CCA-treated lumber was phased out of residential use at the end of 2003 and replaced with ACQ and similar copper-based treatments. The newer chemistry is far more corrosive to steel. Decks built in the years right after the switch were often assembled with the same fasteners, joist hangers and post bases crews had always used — standard galvanised hardware that the new lumber eats.
The result shows up now, twenty-odd years on: hangers rusted thin behind the wood, lag bolts corroded in the ledger, nail heads mushroomed and bleeding. The lumber looks fine. The metal holding it together doesn’t. Current practice is hot-dip galvanised rated for treated lumber, or stainless — which matters even more on the damp, shaded lots common around Braintree.
If your deck dates from roughly 2004 to 2010 and has never had its hardware checked, that’s the inspection to prioritise.
Often, yes — and we’d rather do that. But the honest line sits in a specific place.
Repair makes sense when the damage is surface or isolated. Rotted deck boards on an otherwise sound frame, a failed railing section, one bad stair stringer, corroded hardware on good lumber, a ledger that needs re-flashing and re-bolting. These are real repairs with real lifespans.
Replacement makes sense when the frame is the problem. Multiple soft joists, post bases rotted at grade, footings that have heaved, or a ledger that was never flashed and has been wetting your rim joist for a decade. At that point you’re paying skilled labour to work around a structure that’s failing anyway, and the repair bill starts chasing the rebuild price.
The rough test we use: if the repair runs past about half the cost of a new deck, rebuild. You get a code-compliant structure, current hardware, a fresh start on footings, and a warranty — instead of a patched frame with the same end date.
One more thing worth saying plainly: if the ledger has been leaking, the damage isn’t only in the deck. Water behind a ledger rots the house’s rim joist and sheathing, and that gets found during the repair, not before it.
It depends on whether you’re touching the structure.
Generally no permit for cosmetic, in-kind work — swapping damaged surface boards, replacing a railing section like for like, re-staining.
Generally yes once you’re into structural elements: the ledger, joists, beams, posts or footings. In most Massachusetts towns, rebuilding a deck’s structure rather than just replacing surface boards requires a permit under 780 CMR — and if a contractor is doing it, a licensed Construction Supervisor’s name and licence number go on the application.
Where people get caught out is scope creep. A board replacement that turns into “while we’re in here, these three joists are gone” has become structural work, and it should be permitted. We’ll tell you which side of that line a job falls on at the estimate rather than halfway through. For how permits work on a full rebuild, our Braintree deck construction page walks the process.
We’re at 175 Derby Street in Hingham, roughly fifteen minutes from Braintree — East Braintree, Braintree Highlands, South Braintree and the streets around South Shore Plaza — plus Weymouth, Quincy, Milton, Hingham and Randolph.
Over two decades on the South Shore we’ve repaired about as many failed decks as we’ve built new ones, which is why the assessment comes before the recommendation. If a repair will hold, we’ll say so. The full scope sits on our deck repair and replacement page, and our guide to choosing a deck contractor covers what to ask whoever you hire.
How much does deck repair cost in Braintree, MA?
Small repairs — a few rotted boards, a railing section, hardware replacement — typically run a few hundred to a couple of thousand dollars. Structural work on joists, posts, footings or the ledger costs considerably more. Once a repair passes roughly half the price of a new deck, rebuilding is the better value.
What are the warning signs my deck is unsafe to use?
Wood that a screwdriver sinks into at post bases, stair stringers or joist ends; rust streaks or a gap at the ledger where the deck meets the house; a railing that flexes when you push it; rusted or wrong-fastener joist hangers; bounce or sway underfoot; loose stair stringers.
Can you replace only the damaged boards instead of rebuilding?
Yes, when the frame underneath is sound — that’s a normal repair. If multiple joists are soft, post bases have rotted at grade or footings have heaved, new boards sit on a failing structure and you’ve bought time, not a deck.
Does a deck repair in Braintree need a permit?
Cosmetic, in-kind work like swapping surface boards generally doesn’t. Structural work on the ledger, joists, beams, posts or footings generally does under 780 CMR, with a licensed Construction Supervisor named on the application when a contractor performs it.
How soon can you get out for a deck repair in Braintree?
We prioritise safety issues — a failing ledger, loose railings, rotted stair stringers — and aim to assess those within the same week. Non-urgent repairs are scheduled normally.
