Push on a railing and it moves. Step near the back door and a board gives a little. Look under the deck and there's a post sitting on a cracked block with dark, soft wood at the bottom. These are the most common deck calls, and the question is always the same: can it be fixed, or does it need to come down?
The answer depends on what's going on underneath.
How a deck should be inspected
The surface tells only part of the story. On a free inspection, a good contractor looks at:
- The ledger. How it's attached to the house, whether it's flashed, and whether there's rot behind it or in the house rim joist.
- Footings and posts. Whether posts sit on proper footings, whether they're plumb, and whether there's rot or settling at the base.
- Joists and beams. Soft spots, splits, sagging, and how they're supported.
- Hardware. Hangers, bolts and screws, looking for rust and corrosion, or missing hardware.
- Railings and stairs. How they're attached and whether they hold up to real force.
- Decking. Rot, splits, cupping and loose fasteners.
Expect them to probe suspect wood with a screwdriver or awl. Sound wood resists. Rotted wood gives. They should point out what they find as they go, and you're welcome to look along. Most inspections take under an hour, and you'll get a written quote afterward that explains each item, so you can decide what to fix now and what can wait.
Common problems on Statesville decks
Older homes around town often have decks that were added years ago without flashing, with posts set in the dirt or on blocks, and with nails instead of structural fasteners. Newer builder-grade decks are usually framed to the minimum and may have hardware that's starting to corrode against treated lumber.
Our climate speeds things up. Hot, humid summers and heavy rain keep wood wet. Pine pollen and leaves pack between boards and on top of joists, holding moisture right where rot starts. Decks close to the ground, with little airflow underneath, stay damp the longest. Shaded decks under trees can grow mildew and algae that keep boards slick and wet.
Repair or rebuild?
When repair makes sense
If the ledger, footings, posts and most of the joists are solid, targeted repair is usually the smart move. That might mean:
- Replacing rotted or split deck boards
- Sistering or replacing a few damaged joists
- Adding or replacing hangers and fasteners
- Resetting posts on proper footings
- Tightening or rebuilding railings and stairs
- Adding ledger flashing where it's missing, if the wood behind it is still sound
What a repair costs depends on how much needs to be done and what turns up once boards come up.
When a rebuild is the better call
If the ledger has rotted, the posts have no real footings, or rot runs through many joists, patching usually costs good money to keep a bad frame. A rebuild fixes the structure from the ground up. Sometimes the crew can reuse footings or parts of the frame. Often it's a full tear-out and a new custom deck, with composite or treated decking on top.
Resurfacing an existing frame
If the frame is sound but the boards are shot, replacing just the decking and railings can save a good amount compared with a full rebuild. Joist spacing gets checked first. A frame built at 24-inch spacing for wood may need extra joists added before composite can go on.
What a good contractor won't do
A good contractor won't lay new boards over rotten joists to make a deck look new. They won't tell you a deck needs to come down if a repair will do. And they won't skip the ledger. If they pull boards and find rot behind the ledger or in the house framing, they should show you before going further.
Permits are often required for larger repairs and rebuilds, and the contractor pulls them when needed. For pricing, see the deck building cost guide.
Questions people ask
How do I know if my deck is safe?
Warning signs include railings that move, soft or spongy boards, posts with rot at the base, rusted hangers, and a gap between the deck and the house. If you see any of these, limit use of the deck and have it inspected. A free on-site inspection will tell you what's going on.
Can you just replace the boards on my deck?
Yes, if the frame is sound. The contractor should check the ledger, posts, footings and joists before re-decking. Putting new boards on a frame with hidden rot means you'll be tearing them back up in a few years, so confirm the structure first.
How much does deck repair cost?
It depends on how much of the deck is damaged and where. Replacing a handful of boards or tightening a railing is a small job. Replacing joists, resetting posts or fixing a ledger costs more. Your actual price comes from a free inspection and a written quote.
Is it worth repairing an old deck or should I replace it?
If the structure is sound, repair is almost always the better value. If the ledger is rotted, the footings are inadequate, or rot runs through much of the frame, rebuilding is usually safer and costs less over time. Ask the contractor to show you what they find and quote both options when it's close.
