The cost to replace deck boards often runs $8-$30 per square foot, with a typical 200-square-foot project landing near $3,600 before major framing repairs. A Homewyse estimate can help establish a baseline, but board material, removal needs, deck height, local labor rates, and the amount of damaged framing can move an actual quote substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Wood board replacement | $8 per sq. ft. | $15 per sq. ft. | $24 per sq. ft. | Includes typical materials and installation |
| Composite board replacement | $15 per sq. ft. | $25 per sq. ft. | $38 per sq. ft. | Board grade and fastening system affect price |
| 200-sq.-ft. deck, wood | $1,600 | $3,000 | $4,800 | Assumes accessible deck and sound framing |
| Deck-board labor | $45 per hour | $75 per hour | $110 per hour | Rates vary by market and crew type |
What Homewyse and contractors charge to replace deck boards
For a straightforward replacement using pressure-treated lumber, a useful U.S. planning range is $8-$24 per square foot installed. The middle of the range, about $15 per square foot, represents ordinary materials, removal of existing boards, and installation on a deck with accessible, serviceable joists. Cedar and composite decking commonly push the installed price higher.
For a 200-square-foot deck, budget roughly $1,600-$4,800 for basic wood board replacement, with about $3,000 as a practical average. Smaller jobs may cost more per square foot because contractors often set a minimum charge. A partial repair of a few boards can therefore cost $300-$900 even when the material quantity is low.
Homewyse pricing is best treated as an estimating benchmark, not a guaranteed local quote. Its calculation can reflect selected location, job size, material, and project assumptions; changing those inputs changes the result. Check whether the estimate covers tear-out, disposal, fasteners, trim, and taxes before comparing it with a contractor’s total.
Assumptions: 200-square-foot deck, standard pressure-treated boards, normal access, no structural repairs, and typical U.S. labor rates.
How lumber, removal, and labor shape the replacement quote
Quotes usually combine decking, fasteners, removal, installation labor, and disposal. The following ranges are planning figures for a 200-square-foot wood deck; line items may be bundled rather than separately itemized. Local material prices and the number of cutouts or stairs can alter the totals.
| Quote component | Low | Average | High | Typical basis |
|---|---|---|---|---|
| Pressure-treated boards | $2-$4 per sq. ft. | $4-$6 per sq. ft. | $6-$9 per sq. ft. | Board grade and dimensions |
| Labor to remove and install | $4 per sq. ft. | $8 per sq. ft. | $14 per sq. ft. | Deck access and fastening complexity |
| Fasteners and small supplies | $50 | $125 | $275 | Coated screws or hidden clips |
| Removal and disposal | $150 | $400 | $900 | Old-board volume and haul distance |
| Possible framing allowance | $0 | $300 | $1,500+ | Only if joists or blocking need work |
Material prices are not always a simple share of the installed bill. A premium decking product can require compatible clips, fascia, or color-matched trim, while a low-cost lumber selection may still need extra labor if boards are warped or the deck layout has many angles. Ask whether the estimate includes disposal and fasteners; those omissions can make an apparently low bid incomplete.
Labor can be estimated with a simple check: For example, 20-32 crew labor-hours at $60-$95 per hour equals approximately $1,200-$3,040 before material, disposal, or overhead.
Why board width, wood species, and joist spacing change price
Material choice is one of the largest quote variables. Pressure-treated pine typically costs less than cedar, redwood, or composite. As a broad installed comparison, expect pressure-treated boards at $8-$24 per square foot, cedar or redwood at $14-$32, and common composite products at $15-$38. Premium composite lines or specialty hardwoods can exceed those ranges.
Deck size affects both total and unit price. A 100-square-foot repair might run $1,000-$3,000 because minimum labor and setup are spread across fewer boards. A 400-square-foot replacement may cost $3,200-$9,600 for wood, but larger, open layouts can reduce the average labor charge per square foot.
Spacing and framing determine whether standard boards fit. Deck joists spaced 16 inches on center commonly support standard residential decking, while 24-inch spacing may not meet the product’s installation requirements. If a composite manufacturer calls for 12-inch spacing for a diagonal layout, adding joists or blocking can add $4-$12 per square foot of affected area.
Height and access also matter. A low deck with a clear path for hauling boards is less demanding than a second-story deck with stairs, railings, landscaping, or limited access. Difficult removal can add $300-$1,200 or more. Check joist condition before ordering boards: replacing surface material over rot can leave the underlying safety problem unresolved.
Board dimensions and pattern can affect waste. Diagonal installation, curved edges, picture-frame borders, and numerous posts require more cuts and can raise labor or material waste by 10%-20%. A simple rectangular layout with standard lengths generally costs less than a pattern requiring short custom pieces.
How to lower the deck-board replacement bill without cutting corners
Keep the work limited to boards that are split, soft, badly warped, or unsafe, if the remaining boards match reasonably well and the deck has no widespread deterioration. A small repair may cost $300-$900, while replacing every surface board on a 200-square-foot deck can be several thousand dollars. However, mismatched color and repeated repair visits can make selective replacement less appealing.
Compare material options by installed cost rather than board price alone. Pressure-treated boards are often the economical choice, while composite costs more initially but avoids routine staining. Using a standard board profile and familiar fastening method can also reduce labor compared with specialty colors, hidden clips, or intricate borders.
Prepare the site by moving furniture, planters, and grills, and make access clear before the crew arrives. Confirm whether the contractor expects the homeowner to remove railings or whether that work is included; removing and reinstalling railings may add $200-$800 depending on length and complexity. Do not remove structural pieces without confirming the scope with the contractor.
Obtain two or three written estimates with the same square footage, material grade, removal scope, disposal method, and repair allowance. Ask for a separate price for any joist work so a contingency is not mistaken for guaranteed work. Comparing identical scopes is more useful than selecting the lowest headline price.
What labor time and crew size mean for the final price
A two-person crew may need one to three days for a typical 150-250-square-foot deck with straightforward access and no framing repairs. A small repair can take several hours, although scheduling and minimum charges may still produce a substantial bill. Larger decks, stair surfaces, rail removal, and diagonal board layouts can extend the work to several days.
Contractor labor rates commonly fall around $45-$110 per worker-hour, though some companies price by square foot or bid the project as a fixed amount. A crew-hour is not the same as one worker-hour: two workers on site for eight hours generate 16 worker-hours. Ask whether the quote covers both installation and tear-out labor, plus setup and cleanup.
Unexpected damage may require a pause while the contractor documents the framing and prices a change order. A modest joist-end repair can add $150-$500; replacing several joists or rebuilding a section can add $500-$2,000 or more. The final price depends on access beneath the deck and whether railings, stairs, or attached structures must be disturbed.
How three common deck sizes translate into real quotes
These examples illustrate how scope changes the total. They assume ordinary U.S. labor rates, standard residential access, and no major code or framing work. Regional prices and contractor minimums can produce different bids.
| Scenario | Material and scope | Estimated total | Cost basis |
|---|---|---|---|
| Small repair | Replace 8-12 damaged pressure-treated boards | $450-$1,100 | Trip minimum plus removal and disposal |
| Mid-size surface | 200 sq. ft. pressure-treated, full board removal | $2,000-$4,800 | $10-$24 per sq. ft. |
| Premium resurfacing | 300 sq. ft. composite with old boards removed | $5,400-$11,400 | $18-$38 per sq. ft. |
For the 200-square-foot example, a simple rectangular layout with clear access may fall near $2,000-$3,500. Adding stairs, railing removal, or a picture-frame border can move the quote toward $4,800. For the composite example, the upper range is more likely when the product uses hidden clips, color-matched fascia, or higher-priced boards.
How regional labor rates shift deck replacement estimates
Prices can vary by roughly 10%-25% between lower-cost rural markets and expensive metropolitan areas. Local contractor availability, travel distance, disposal fees, and lumber supply all contribute. A $3,000 estimate in a mid-cost market could be around $2,400-$2,700 in a lower-cost area or $3,300-$3,750 in a high-cost city for similar work.
Coastal locations may have higher demand for rot-resistant materials, while regions with freeze-thaw cycles may require closer attention to drainage and fastening. These differences do not create a fixed regional surcharge; product availability and local conditions matter. Use a local Homewyse setting where available, then compare it with itemized bids from contractors serving the same area.
Ask whether a quote includes sales tax, delivery, and haul-away. Delivery charges may be $50-$250 for a standard order, with higher fees for remote properties or difficult drops. Dump fees can add $75-$300 or more depending on local disposal rules and the volume of treated or composite material.
Repairing a few boards versus replacing the whole surface
Replacing individual boards is usually less expensive when damage is isolated and replacement lumber can be matched. A contractor may charge $15-$40 per board installed for simple access, with a minimum visit fee; unusual lengths, edge boards, or boards trapped under railings cost more. If many boards are deteriorated, full resurfacing can be more economical per square foot and produce a consistent appearance.
Resurfacing is not the same as rebuilding. If joists, ledger connections, posts, or footings are damaged, the project may need structural repair or reconstruction rather than new boards alone. Framing repairs can add hundreds or thousands of dollars, and a full deck rebuild may substantially exceed the ranges in this article.
For a deck with sound framing, compare a selective repair, a full wood-board replacement, and a composite upgrade as separate options. Include any added framing, fascia, and railing work in each quote. Choose board-only replacement only after the supporting structure is checked and the contractor states what is excluded.
Before approving work, verify the product grade, board thickness, fastening approach, disposal plan, labor warranty, and payment schedule in writing. Permit requirements are local and may depend on whether the project changes the deck structure, dimensions, height, or guardrails; replacing surface boards alone may be treated differently from rebuilding. A contractor or local building department can clarify the applicable rule.
