Many decks in Litchfield County were built in the 1980s and 1990s and are near the end of their life. A replacement can be a full tear-off and rebuild, or new boards and railings on a frame that's still sound.
Signs it’s time to replace a deck
A few soft boards can be fixed. These signs usually mean the deck as a whole is done:
- The ledger is rotted or not flashed. Push a screwdriver into the board where the deck meets the house. If it sinks in easily, water has been getting in for years, and the house rim joist may be damaged too.
- Posts are buried in the ground or sitting on rocks. Older decks often had posts set straight into dirt. They rot at the base and the deck starts to lean.
- Joists are soft or split. Look underneath with a flashlight. Dark, spongy wood near the top of the joists, where water sits under the boards, is a bad sign.
- The deck sways. If it moves side to side when people walk on it, the bracing or ledger connection is failing.
- The railing moves. Railing posts that were only nailed to the outside of the frame loosen over time. A loose railing on a high deck is a real safety problem.
- Rusted hardware. Joist hangers and nails that weren’t rated for treated lumber can corrode until there’s almost nothing left.
Replace everything, or keep the frame
There are two kinds of deck replacement.
Full tear-off and rebuild. The old deck comes down to the footings, or the footings come out too, and a new deck is built to current code. This is the right call when the ledger, posts, or joists are failing, or when the old deck was never built to code in the first place. It also lets you change the size or shape.
Resurface (new boards and rails on the old frame). If the footings are deep enough, the posts sit on proper bases, the ledger is flashed and bolted, and the joists are solid, the builder can keep the frame and put on new decking, stairs, and railings. This costs less, usually 50 to 70 percent of a full rebuild.
Be careful with resurfacing when you switch to composite. Composite boards often need joists at 12 inches apart instead of 16, especially for diagonal patterns, and the frame has to be flat. A good builder will check spacing and add joists or sister old ones before laying new boards. A composite board on a 30-year-old frame can outlast the frame by a decade or more, so it pays to be honest about the frame’s condition.
How the tear-off works
- Inspection. The builder pulls a few boards, checks the ledger and footings, and tells you which kind of replacement makes sense.
- Permit. A rebuild usually needs a new building permit. A board-only resurface may not, depending on the town. The builder will check with your building department.
- Demolition. Old boards, rails, and framing are removed and hauled away. Treated wood from before 2004 contains arsenic (CCA treatment), so it shouldn’t be burned. Builders take it to a transfer station.
- Footings and ledger. New footings go 42 inches deep. The house rim joist is checked, and any rot is repaired before the new ledger is flashed and bolted on.
- New deck. Framing, boards, stairs, and railings, followed by the final inspection.
A full replacement usually takes about a week of work on site.
What it costs
| Job | Typical range (Litchfield County, 2026) |
|---|---|
| Tear-off and haul-away only | $1,500–4,000 |
| Resurface 12×16 in pressure-treated, new rails | $5,000–8,000 |
| Resurface 12×16 in composite, new rails | $8,000–13,000 |
| Full rebuild 12×16 in pressure-treated | $7,500–12,000 |
| Full rebuild 12×16 in composite | $12,500–19,000 |
Second-story decks, extra stairs, and rot in the house framing all add to the price. See the full deck cost guide.
Upgrades worth doing while it’s apart
- Switch to composite or PVC if you’re tired of staining.
- Hidden fasteners so no screw heads show on top.
- Aluminum or cable railing for a cleaner view of the yard. See railings and stairs.
- Wider stairs with a landing, which are easier to use and safer in snow.
- Low-voltage post cap or stair lights.
- A roof or screen room over part of the deck. See covered decks and porches.
Common questions
Can I just replace the boards?
Only if the frame is sound. A builder should check the ledger, posts, footings, and joists first. New boards on a failing frame waste money.
Is old pressure-treated wood dangerous?
Lumber treated before 2004 was usually CCA, which contains arsenic. It’s fine to leave in place, but don’t burn it or use the sawdust in gardens. Wash your hands after handling it. Builders dispose of it properly.
Will I need a new permit?
For a full rebuild, almost always. For new boards and rails only, it depends on the town. Ask your builder to check with the building department before work starts.
How long does a replacement take?
Most single-level replacements take four to eight working days on site, plus time for the permit and inspections.
