Repair or Replace an Old Wood Deck? The Inspection That Decides It in Indian River County
Start Your Transformation
How to walk an aging wood deck from the footings up, what the age of the lumber tells you, and when a patch stops making sense in Vero Beach and the rest of Indian River County.
Quick Answer:
The boards don't decide it — the frame does. If the posts, footings, joists, and ledger are sound, an old wood deck in Indian River County can usually be repaired or re-boarded. If the frame is failing in more than one place, or the guards and stairs can't be made safe, replacing it is the better money.

Start Below the Boards
Gray, splintered boards make a deck look finished. Usually they're the least important part of the call.
Boards are the wear layer. They take the sun, the rain, and the foot traffic, and they're built to be swapped. What holds the deck up is underneath: posts, footings, beams, joists, and, on an attached deck, the ledger bolted to your house.
So the real question isn't "do the boards look bad?" It's this:
- Is the frame still sound? Then you're looking at repair or new boards.
- Is the frame failing? Then new boards on top just hide the problem for a while.
- Are the guards and stairs safe? That's the part people lean on, literally.

The Five-Point Structural Walk
Grab a flashlight and a flat screwdriver, and go underneath. Work from the ground up:
- Posts and footings. Push on each post. It shouldn't rock. Probe the wood right at grade, where it stays wettest. Look for footings that have sunk, tipped, or cracked.
- Beams and joists. Look for sag, splits at the hangers, and soft spots on the joist tops where water sits under the boards. A screwdriver that sinks in easily means rot.
- The ledger. On an attached deck, check where it meets the house. Water stains, missing flashing, or soft wood there is the most serious find on the list.
- Connectors and fasteners. Hangers and bolts that are flaking rust or missing nails aren't carrying their load.
- Guards and stairs. Grab the rail and shake it. Walk the stairs and feel for bounce or a loose stringer.
Plenty of Indian River County houses are concrete block, and the ledger connection on block works differently than on a wood wall. Our attached vs. freestanding deck guide explains why.
How Old Is Your Deck, Really?
Age matters for two reasons: the lumber it was built with, and the rules it was built to.
The lumber. According to the EPA, manufacturers stopped making chromated copper arsenate (CCA) treated wood for most homeowner uses in December 2003. Decks built before 2004 may well be CCA. The EPA says:
- You don't have to tear it out. The EPA doesn't require removal of existing CCA structures.
- Never burn it. Burning treated wood releases toxic chemicals in the smoke and ash.
- Saw it carefully. Wear goggles and a dust mask, and wash your hands after handling it.
- Check disposal rules locally. It can often go out with regular trash, but check with your local waste program first, and never reuse it as mulch.
The rules. A deck built decades ago was built to the code of its day. Guards, stairs, and ledger connections are all spelled out more tightly now. That doesn't make an old deck illegal. It does mean a replacement gets built to today's code, not yesterday's.

Repair, Re-Board, or Replace
Once you've walked it, the call usually makes itself:
- Repair. A few soft boards, a loose rail post, popped fasteners, or one rusted hanger, on a frame that's otherwise solid.
- Re-board. The surface is worn out, but posts, joists, and ledger all pass. New boards on a good frame is a sound investment.
- Replace. Rot in several joists, a soft or leaking ledger, posts rotting at grade, sunken footings, or guards and stairs that can't be made safe without rebuilding them.
Thinking of switching to composite while you're at it? Composite boards carry a labeled maximum span under the Florida Building Code, Residential (R507.2), so the old joist spacing has to be checked first. Our wood vs. composite guide covers that choice.
📌 The Repair-or-Replace Checklist
- Posts solid, no rot at grade
- Footings level, not sunk or cracked
- Joist tops firm under a screwdriver
- Ledger dry, flashed, and tight to the house
- Hangers and bolts intact, not flaking
- Rails don't move, stairs don't bounce
❌ Two or more fails in the frame? Plan on replacing it.
Permits and Code When You Replace
Replacing a deck means building a new one, so it goes through the building department like any new deck.
Which office depends on your address:
- City of Vero Beach and unincorporated Indian River County: the county Building Division at 1801 27th Street.
- Sebastian, Indian River Shores, and Orchid: each runs its own building department.
A replacement is built to the current Florida Building Code, Residential. On a raised deck, that means a few things inspectors check closely:
- Guards where the deck is more than 30 inches above grade, at least 36 inches tall, with no opening a 4-inch sphere can pass (R312.1.1–R312.1.3).
- Stairs with risers no taller than 7¾ inches, treads at least 10 inches deep, and a handrail once there are four or more risers (R311.7.5, R311.7.8).
- The ledger or freestanding frame, shown on the drawings and inspected before boards cover it.
On the barrier island or near the lagoon, check your flood zone on FEMA's Flood Map Service Center before you design anything. A mapped zone adds to the review.
What a Replacement Looks Like With Us
When the frame is done, we build the new deck from the footings up:
- Wood: high-moisture-resistant pressure-treated wood decking.
- Composite: TimberTech, AZEK, Deckorators, or Trex. We're a certified pro on those brands.
- Attached or freestanding: we build both, and pull the permit on both.
- Timeline: built by our own crew in 1–2 weeks once the permit is in hand.
- Warranty: our 2-year workmanship warranty, on top of the board maker's own.
What moves the price is deck size and height, wood or composite, rails and stairs, the ledger or freestanding frame, and how much of the old deck has to come out. We price it on-site, and you get a real number at the consultation.
FAQs
Can I just replace the boards on my old wood deck?
Yes, if the frame passes. Re-boarding makes sense when posts, footings, joists, and the ledger are solid and only the surface is worn. If the screwdriver sinks into joist tops or the ledger is soft, new boards just hide the problem. In Indian River County, the frame is the first thing we check at the consultation.
Was my old deck built with arsenic-treated wood?
Yes, possibly, if it was built before 2004. The EPA says manufacturers stopped making CCA-treated wood for most homeowner uses in December 2003. You don't have to remove it, but never burn it, wear a mask when cutting it, and check local disposal rules. If yours is due for replacing, we build the new one in pressure-treated wood or composite.
Do I have to bring an old deck up to today's code when I replace it?
Yes. A replacement deck is new construction, so it's built and inspected to the current Florida Building Code, Residential, including guard height, stair dimensions, and the ledger or freestanding frame. In Vero Beach and unincorporated Indian River County, the county Building Division reviews it. We pull that permit for you.
