If your deck has gone soft underfoot, the railing moves when you lean on it, or one corner sits lower than it used to, you are probably weighing a repair against a rebuild. Most prices online are national, and they rarely line up. This guide keeps national and Dallas figures apart and names the source for each number. For new-deck prices in detail, see our Dallas deck cost guide.
Should you repair or replace your deck?
Repair when the problem is local and the frame is sound; replace when the ledger, several joists or the footings have failed. Block Renovation’s 2026 deck remodeling guide says new boards and railing on the old frame are the right choice when the joists, beams and posts are solid, with no soft spots at the ends or bases, the footings are intact, the ledger is bolted and flashed, and you are keeping the same footprint, height and stairs. It says a full rebuild makes sense when the frame has soft spots, the footings are shallow or shifting, the ledger is nailed rather than bolted and flashed, or you want to change the footprint or stairs.
Two other sources point the same way. InspectandTest says rot in the ledger plus several joists usually makes replacement the better long-term value. Bob Vila notes that multiple spots of extensive wood rot may call for a full replacement.
Signs a deck needs replacing, not repairing (ledger, joists, footings, railings)
The signs that matter are under the boards: a ledger pulling away from the house, soft joists, footings that have moved, and guard posts that flex. Worn or cracked surface boards on their own are usually a repair. The checks below come from the North American Deck and Railing Association (NADRA), TimberTech, Decks.com and the Journal of Light Construction (JLC).
Ledger
The ledger is the board that ties the deck to the house. TimberTech lists a ledger pulling away from the home because of pervasive rot as a sign it is time to replace the deck. NADRA’s evaluation checklist, as summarized by Pro Builder, says to check what fasteners hold the ledger and whether it is flashed, and that a ledger must not hang on brick or masonry veneer.
Joists and beams
Decks.com suggests a simple screwdriver test: if the tool sinks in more than 1/8 inch with little resistance, replacement may be needed. TimberTech treats pervasive rot in the substructure as a replacement sign. NADRA also says to look for split or decaying wood on the ledger, posts, joists, boards, railings and stairs, and for loose or corroded fasteners. Its evaluation checklist calls for at least 1½ inches of joist bearing.
Footings and posts
JLC’s deck-builder checklist flags footings that have heaved or dropped and missing metal connectors where posts meet footings. NADRA’s checklist says footings should go at least 12 inches into undisturbed ground. A deck that sags or sways is on NADRA’s homeowner list too.
Railings and stairs
Push on the railing. JLC says a railing that moves more than an inch or two at the top should be replaced, and puts it plainly: "If it doesn’t feel safe, it probably isn’t safe." NADRA says balusters should be no more than 4 inches apart. Check the stairs as part of the same walk-around.
Termites
Texas A&M’s Urban and Structural Entomology Program says wherever wood touches the soil, the risk of termites is high. Signs include wood that sounds dull when tapped, mud in the galleries and shelter tubes. Posts set straight in the dirt are the first place to look.
How much does deck repair cost in 2026?
National guides put a typical deck repair at about $1,465 to $2,019, but structural work runs far higher. Fixr’s national guide (updated January 2025) gives a range of $500 to $3,000 with a $1,500 average, Lawn Love (October 2026) a $1,465 average with most jobs between $570 and $2,600, and Bob Vila (2024) $859 to $3,321 with a $2,019 average. No Dallas-only repair figure could be sourced, so every number in this table is national.

|---|---|---|---|---|
| Typical repair overall | $500 to $3,000; average $1,500 | $570 to $2,600; average $1,465 | Not given | $859 to $3,321; average $2,019 |

Why deck repair cost averages contradict each other
An "average repair" mixes $150 nail jobs with $10,000 termite rebuilds, and the cheapest guides leave out ledger work. Fixr’s own examples run from $150 for replacing missing nails on a 300 sq ft deck to $10,000 for extensive termite damage on a 500 sq ft hardwood deck. An average across that spread mostly describes small jobs.
Four things make the guides disagree:
- Different units. Boards are priced per square foot, joists and posts per piece, stairs per step, railing per linear foot, and the averages per job.
- Missing structural work. Lawn Love gives no price for a ledger or a footing, and Fixr gives no ledger price and puts a replacement footing at $300 to $400. InspectandTest puts a ledger with new flashing at $1,500 to $6,000 or more and footings at $500 to $1,500 each. One ledger and a handful of footings can cost more than Fixr’s whole typical repair range on their own.
- "Repair" sometimes means resurfacing. Block Renovation prices new boards and railing on a 200 to 300 sq ft deck at $5,000 to $12,000, which is more than most "average repair" figures.
- National data from different years. The repair figures here run from 2024 to 2026, and none of them is Dallas-specific.
An average tells you little about your deck. What is under the boards decides the price.
How much does it cost to replace a deck in Dallas?
A new deck in Dallas costs about $15 to $30 per square foot installed in pressure-treated wood and $25 to $50 per square foot in composite (Block Renovation, 2026 Dallas guide). That is the best local baseline for a replacement. The other figures below are national. Some include tearing out the old deck, and the Decks.com figures are materials only.
| Source | What it covers | Price |
|---|---|---|
| Block Renovation, Dallas guide (2026) | New deck, pressure-treated, installed (Dallas) | $15 to $30 per sq ft |
| Block Renovation, Dallas guide (2026) | New deck, composite, installed (Dallas) | $25 to $50 per sq ft |
| Block Renovation, remodeling guide (2026) | New boards and railing, 200 to 300 sq ft, 1 to 2 weeks (national) | $5,000 to $12,000 |
| Block Renovation, remodeling guide (2026) | Full rebuild, single level, 300 to 400 sq ft, 2 to 4 weeks (national) | $14,000 to $35,000 |
| Block Renovation, remodeling guide (2026) | Multi-level or custom rebuild (national) | $35,000 to $75,000 |
| Lawn Love (2026) | Removal plus new deck installation (national) | $5,420 to $14,540 |
| Bob Vila (2024) | Deck replacement (national) | $6,000 to $18,600 |
| Decks.com (2025) | 300 sq ft deck with 50 linear ft of railing, materials only (DIY estimate), excluding planning, permits and hauling (national) | $3,160 to $14,850+ |
| Decks.com (2025) | Disposal of the old deck, DIY: landfill fees; dumpster rental (national) | $80 to $180; $300 to $500 |
Here is a worked example using Block Renovation’s Dallas rates. A 300 sq ft replacement at $15 to $30 per square foot is 300 × $15 = $4,500 to 300 × $30 = $9,000 in pressure-treated wood. In composite it is 300 × $25 = $7,500 to 300 × $50 = $15,000. Those totals are before demolition, stairs, railing upgrades and permits. Block notes that demolition and disposal are priced separately from the build.
A rebuild is also the natural time to change the design, since Block Renovation notes that changing the footprint or moving the stairs requires reframing anyway. You can choose a composite deck instead of wood, or add a cover or pergola when you rebuild. If you want a roof over the new deck, see covered decks and pavilions. See how Archetex builds a new deck in Dallas.
The 50% rule: when repair costs say replace
Price a replacement once a repair quote nears half the cost of a new deck the same size. It is a rule of thumb, not a building code, and the sources draw the line in different places:
- InspectandTest (2026): price replacement seriously once repairs approach about half the cost of a new deck, and treat that as a rule of thumb, not an engineering standard.
- Bob Vila (2022): replace if repairs would cost more than half the cost of a deck replacement.
- Fixr (2025): replace if the repairs come close to the price of a new deck.
- TimberTech (2021): consider replacing when repairs are "close to, equal to, or greater than" the cost of a full replacement.
To apply it in Dallas, take half of the worked example above. Half of $4,500 to $9,000 is $2,250 to $4,500 for a 300 sq ft pressure-treated deck. Half of $7,500 to $15,000 is $3,750 to $7,500 in composite. A repair quote in that zone is a signal to get a replacement price as well. If the quote includes a ledger or footings, it can reach that zone quickly: a ledger with new flashing alone runs $1,500 to $6,000 or more nationally (InspectandTest).
Age matters too. Lawn Love says that if the deck is due for replacement in the next couple of years and then gets storm or termite damage, it is probably best to get a new deck.
Can you put new boards on old joists?
Only if the joists, beams, posts, ledger and footings are sound, and composite boards often need tighter joist spacing too. InspectandTest says that with widespread joist rot, a weak ledger or failing footings, new boards will not fix the deck.
When the frame passes, InspectandTest puts resurfacing at roughly $15 to $30 per square foot in pressure-treated wood and $25 to $50 or more in composite. Note that those per-foot figures overlap Block’s Dallas prices for a whole new deck. Ask for both prices before you decide. If you are switching from wood to composite, ask whether the old joists are spaced closely enough for the new boards.
How long does a deck last? Lifespan by material
For the full breakdown of boards, frame and hardware by material, see how long a deck lasts in Texas. The short version for the repair-or-replace decision is below.
A pressure-treated deck lasts about 10 to 15 years and composite about 25 to 30, by most guides. Fixr gives about 20 years as a general figure. No source gives a Texas-specific lifespan, so all of these are national.
| Material | Lawn Love (2026) | Block Renovation (2026) | Bob Vila (2022) |
|---|---|---|---|
| Pressure-treated pine | 10 to 15 years | 10 to 15 years | 10 to 15 years (wood) |
| Cedar | 15 to 20 years | 15 to 25 years (cedar or redwood) | 10 to 15 years (wood) |
| Composite | 25 to 30 years | 25 to 30 years | 20 to 25 years |
| PVC, aluminum or capped polymer | Not given | 30+ years (PVC and aluminum) | Up to 50 years (capped polymer) |
TimberTech also puts wood decks at 10 to 15 years. If your wood deck is in that range and the frame is showing the signs above, the replacement price is worth getting now.
Dallas clay and deck footings
Blackland Prairie clay swells when wet and shrinks when dry, so footings can heave or drop and a deck slowly tilts. The Blackland Prairie runs from the Texas border north of Dallas to just south of San Antonio, along I-35 (Soil Science Society of America). The SSSA notes that its smectite clays crack when dry and that "construction on this soil is often plagued by cracking."
For a deck, that puts the footings first on the inspection list. NADRA’s 12-inch minimum into undisturbed ground is a general check, not a Dallas rule. No source gives a Dallas-specific footing depth, so ask how deep any new footings will go and why. Block Renovation lists shallow or shifting footings as a reason to rebuild rather than resurface.
Because wood touching soil invites termites (see above), a replacement is also the moment to get posts off the dirt and onto proper footings with metal connectors.
Railing code: what a replacement deck has to meet
A guard is required where the deck is more than 30 inches above grade, it should be at least 36 inches high, and it must resist a 200 lb load. Under the 2021 International Residential Code (R312.1.1), a guard is required where the walking surface is more than 30 inches above the floor or grade within 36 inches horizontally. JLC explains that the 2021 IRC requires a guard to resist a 200 lb concentrated load outward and downward.
NADRA’s evaluation checklist adds the details that old decks often miss:
- Guard height at least 36 inches, ideally 42.
- Balusters less than 4 inches apart on the deck and 4⅜ inches on stairs.
- The triangle under the stair rail smaller than 6 inches.
- A shear connection between each guard post and the frame.
JLC puts stair rails at 34 to 38 inches above the stair nosing. Ask your city which code edition it enforces before you finalize the design.
Permits for deck replacement in Dallas
Check with City of Dallas Development Services, or your suburb’s building department, before any rebuild or structural work starts. Block Renovation’s 2026 Dallas guide says elevated decks typically need permits. Nationally, Decks.com puts deck permit fees at $50 to $700. For the City of Dallas fee schedule itself, see the permit section of our Dallas deck cost guide.
Suburbs set their own rules and fees, so check with your city: Dallas, Plano, Frisco, McKinney, Richardson, Garland or Rockwall. There are also local deck pages for Richardson, Garland and Rowlett. If you have an HOA, check it before you change the footprint. Block Renovation notes that HOA rules often require setbacks of 5 to 15 feet from rear and side boundaries. TexasLawHelp.org says the contractor should pull the permits.
Dallas TX deck repair companies and contractors: how to get a written quote
Get a written, itemized quote for both repair and replacement from someone who has looked under the deck. Texas does not require general contractors to be licensed or bonded, so the checks are up to you (TexasLawHelp.org). TexasLawHelp.org advises asking for proof of insurance and three references, getting a written contract, having the contractor pull the permits, and not paying in full up front.
A quote you can compare should list each of these as its own line:
- Ledger and flashing: inspected, re-fastened or replaced.
- Joists: how many, and repaired or replaced.
- Posts and footings: how many, and how deep.
- Railing: type, height and baluster spacing.
- Stairs: repaired or rebuilt.
- Demolition and haul-off.
- The permit, and who pulls it.
- How hidden rot found after the boards come up will be priced.
That last line matters most on a repair, because a quote can move a long way once the boards are off.
If the frame has failed and a new deck is the honest answer, that is the work Archetex does. Archetex builds new and replacement decks in wood and composite, with footings and framing sized to the home’s elevation and load, not a one-size prefab kit, and railings built to code from the start. Matthew will look at the frame and tell you whether a rebuild makes sense, then give a written price after a free site visit. You can see finished decks on our work page, read about the Dallas deck builder service, or contact us to book a visit. Call or text (430) 318-6275.
