Most homeowners pay $750–$3,000 for deck repair, with averages reported between about $1,500 and $2,250. Small fixes like loose boards or popped nails can cost under $500, while extensive rot or termite damage can reach $10,000 (Angi, HomeGuide, Fixr and HomeAdvisor data, as of October 2026).

Deck repairs range from resetting popped nails to replacing rotted joists and failing footings. Catching problems early, such as soft boards, wobbly railings or loose stairs, keeps a repair small and keeps the deck safe to use.
Below are typical repair costs by problem, a breakdown for a common mid-size repair, and tips to keep costs down. If the damage is widespread or the deck is 15 years old or more, compare these figures with our deck replacement cost guide.
Average cost
Typical deck repair costs, national averages as of October 2026:
| Scenario | Typical range | Notes |
|---|---|---|
| Simple repair (loose boards, popped nails, a stair tread) | $100–$750 | Often a few hours of handyman or carpenter time |
| Average repair (several boards, a joist or two, railing fixes) | $750–$3,000 | Most common range; averages about $1,500–$2,250 |
| Major repair (widespread rot, framing, footings, termite damage) | $2,500–$10,000+ | At this level, compare with full replacement |
Deck repair cost by type of repair
| Repair | Typical cost | Notes |
|---|---|---|
| Replace deck boards | $10–$35 per sq. ft. (repair) or $125–$625 per board | Wood is cheapest; composite and PVC cost more |
| Repair or replace a joist | $100–$350 per joist | Sistering a new joist is usually cheaper than full replacement |
| Replace a post | $150–$500 per post | Rot at the base is common |
| Replace a footing | $300–$400 per footing | May require temporary shoring |
| Railing repair | $150–$5,000 | Replacement runs $20–$250 per linear foot by material |
| Stair repair | $15–$300 per step | New stairs cost $1,400–$2,600 |
| Rot repair (pro) | $200–$700 for minor rot | Extensive rot can reach $5,000 |
| Termite or pest treatment | $200–$600 | Plus repairs to damaged wood |
Cost breakdown: materials, labor, permits and extras
Line-item estimate for a mid-size wood deck repair: replacing about 40 sq. ft. of rotted boards, sistering two joists and replacing one railing post. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Materials (boards, joist lumber, fasteners) | $200–$700 | Pressure-treated or cedar to match the existing deck |
| Labor | $400–$1,500 | Carpenters typically charge $50–$100 per hour |
| Railing post replacement | $150–$500 | Per post, including new hardware |
| Inspection | $0–$200 | Many contractors waive it; in-depth inspections cost up to $200 |
| Contingency (about 10%) | $100–$300 | Hidden rot found once boards come up |
| Estimated total | $850–$3,200 | Before any discounts or rebates |
Labor is the biggest variable: the same repair can cost twice as much if the damaged area is hard to reach or under a hot tub or built-ins.
What affects the price
- Extent of damage. Surface problems such as popped nails cost as little as $0.30 per sq. ft. to fix, while rot that reaches the framing or termite damage can push a repair from a few hundred dollars to $5,000–$10,000.
- Boards and joists. Replacing boards costs about $10–$35 per sq. ft. for repairs, or $125–$625 per board depending on length and material. Joists cost about $100–$350 each to repair or replace, and posts $150–$500 each.
- Staining. Refinishing after repairs helps new boards blend in and protects the wood. Professional staining runs about $550–$1,250, and full refinishing with sanding about $3.00–$6.50 per sq. ft. See our deck staining cost guide for details.
- Railing. Fixing loose balusters or posts can cost a few hundred dollars, while replacing a railing runs $40–$60 per linear foot for wood and more for metal, composite, cable or glass. Loose railings are a safety issue and should be fixed promptly.
- Footings. Sunken, cracked or undersized footings cost about $300–$400 each to replace, and the deck may need temporary support while the work is done. Footing problems often show up as a sagging or bouncing deck.
Ways to save
- Inspect your deck every spring and fix small issues, such as popped nails, loose screws and a single soft board, before water and rot spread.
- Bundle repairs into one visit; many contractors have a minimum charge, so several small fixes cost less together than separately.
- Ask whether damaged joists can be sistered (a new joist fastened alongside) rather than fully replaced.
- Clean and reseal the deck regularly. Pressure washing costs about $200–$450 and protects against the mildew and moisture that lead to rot.
- Get at least three quotes and ask each contractor to note the condition of the ledger, footings and framing so you know whether repair still makes sense.
How to get an accurate quote
Ask at least three licensed, insured contractors for written quotes after an on-site inspection. Before they visit:
- Make a list of every problem you've noticed: soft or cracked boards, wobbly railings, loose stairs, sagging spots or rust on hardware.
- Note the deck's age, size, height and material, and whether it is attached to the house.
- Ask each contractor to price boards, framing, railings and refinishing as separate line items.
- Ask whether a permit is needed for structural work and what warranty covers the repair.
FAQ
Is it worth repairing an old deck?
It is usually worth repairing a deck with isolated damage and sound framing. If repairs would exceed about half the cost of a new deck, or the deck is 15 or more years old with widespread rot, replacement is often the better value.
Does deck repair need a permit?
Minor repairs such as replacing boards or a few balusters usually don't require a permit. Structural work, like replacing joists, beams, footings or the ledger, often does, so check with your local building department.
Can I repair a deck myself?
Replacing a few boards or tightening fasteners is a common DIY task with basic tools. Structural repairs to joists, footings or the ledger affect safety and are best left to a qualified contractor.
