How Much Does Deck Replacement or Repair Cost? [2025 Data]
The average deck repair cost is $2,161, but it can range between $864 and $3,485, depending on the deck’s size and material.
A few popped nails or loose boards can be easily replaced for $100 or less.
Mold, weather, or termite damage can be much more costly to repair, especially if it impacts the deck's integrity.
Cedar decks are the most affordable to repair, while composite or recycled plastic decks are nearly six times as expensive.
If the damage is widespread or there’s significant warping or cracking, it’s in your home and your wallet’s best interest to replace the deck completely.
For an average cost of $2,161, you can get deck repairs done, like fixing boards, loose steps, and wobbly railings, to get it looking great and operating safely. Depending on your deck type, expect to pay $3 to $45 per square foot in materials for the repair. Deck replacement costs $7,900 due to additional materials and extensive labor.
Hanging out on your deck is a nice way to unwind from a busy day, but structural issues can make your space unsafe or uncomfortable. Here’s how to budget for deck repairs so you can get back to enjoying your yard.
Deck Size
The size of the repair area plays a major role in the cost of deck repair or total deck replacement. To get an idea of repair costs, you can inspect your deck and measure the problem areas. The materials for deck repairs cost between $3 and $45 per square foot, with the type of deck also influencing the cost. Larger areas will also carry higher material costs and greater labor costs.
Average Cost to Repair a Deck
| Deck Size | Repair Cost Range |
|---|---|
| 10-by-10 | $300–$4,500 |
| 12-by-12 | $432–$6,480 |
| 12-by-14 | $504–$7,560 |
| 14-by-14 | $588–$8,820 |
| 14-by-16 | $672–$10,080 |
| 14-by-20 | $840–$12,600 |
| 16-by-16 | $768–$11,520 |
| 16-by-18 | $864–$12,960 |
| 20-by-20 | $1,200–$18,000 |
Size also impacts the cost of rebuilding a deck or starting one from scratch. The average cost to build a new deck ranges between $4,500 and $18,000. The larger the deck, the more the build costs—at around $30 to $60 per square foot.
Deck Contractor Costs
Hiring a reputable, professional deck contractor will help you get the project done right the first time. State laws may require your contractor to hold a current builder’s license to work on decks. Check your local laws and ask for licensing information before hiring someone.
Labor costs between $50 and $100 per hour, with most projects taking two to five hours. Set aside at least $100 to $500 for labor. Expect costs and project times to increase if you’re replacing a deck.
Your deck contractor will handle all aspects of your deck project, from assessing the necessary repairs and removing old deck parts to installing the replacement parts.
Decking Materials
The cost of replacing broken boards depends on the deck materials and the best wood for your deck. Different deck board materials also have varying life spans, so you may need to replace certain types more often than others.
| Decking Material | Average Cost (Per Square Foot) | Benefit |
|---|---|---|
| Cedar | $3–$7 | Rich color and cedar smell |
| Pressure treated lumber | $8–$20 | Easy to install and maintain |
| Ipe Hardwood | $10–$20 | Lifespan of 30 to 50 years, resistant to rotting |
| Redwood | $5–$30 | Unique grain patterns |
| Composite wood | $12–$45 | Low initial cost and weather-resistant |
| Recycled plastic lumber | $30–$45 | Resistant to weather and decay, doesn’t splinter or warp |
Deck Repair Cost by Type
If your deck just needs a repair or two, the cost depends on the issue. Minor cosmetic fixes will cost much less than major structural repairs.
Here are some common decking issues that you may encounter when evaluating your deck for repairs:
| Decking Issue | Average Cost to Repair |
|---|---|
| Railing Repairs | $500–$4,000 |
| Popped Nails or Screws | $0.30 per square foot |
| Loose Stairs | $25–$50 per stair |
| Mold and Rot | $200–$500 |
| Mildew | $50–$110 |
| Board Replacement | $500–$4,000 |
| Termite or Other Pests | $200–$600 |
| Resurfacing | $15–$50 per square foot |
| Refurbishing | $100–$2,000+ |
| Stair anchoring | $15–$40 per step |
| Pressure washing | $200–$450 |
Railing Repairs
Depending on the extent of the damage, railing repairs can cost about $500 to $4,000 or more. Again, the type of material will make a big difference, with cable and composite railings costing the most.
Popped Nails or Screws
Popped nails or screws cost an average of $0.30 per square foot to repair. While this might seem like a minor issue, a simple screw can make a big difference in the overall stability and safety of the area, especially on stairs. Luckily, this is one of the easiest DIYs if you’re a handy homeowner.
Loose Stairs
Deck stairs cost an average of $25 to $50 per stair to fix. Loose, wobbly stairs create a major tripping hazard, which is important to address ASAP. Be sure to check for loose or missing nails and screws before attempting any major work, as these are often the source of the problem. However, if there seems to be an issue with the overall structural integrity of the stairs, more serious repairs may be necessary.
Mold, Rot, and Mildew Issues
If mold is the primary issue affecting your deck and the damaged area isn’t weight-bearing, you can trim away damaged wood on your own and fill in the area with an epoxy compound. These compounds cost $35 to $70 per quart or $100 to $200 per gallon. A pro charges about $200 to $500 for this repair.
Mildew, on the other hand, can be power washed. If you don’t own a power washer, you can rent one for $40 to $75 per day and purchase cleaning supplies for $10 to $30. However, know that incorrect power washing can lead to further damage to your deck’s structure and appearance, so you’ll want to have a good handle on your approach and technique for this project.
Termite and Pest Control
Professional termite and pest control on a deck costs an average of $200 to $600. Staining and sealing your deck every two to three years can dramatically decrease the likelihood of infestations.
Resurfacing
Resurfacing a deck costs around $15 to $50 per square foot. This project totally transforms the look of a deck by replacing decking boards, stairs, and railings while keeping the underlying base structure intact.
Refurbishing
Refurbishing a deck averages $100 to $2,000 or more, depending on the materials and the extent of the work. Refurbishing involves minor cosmetic fixes, such as sanding, restaining, and replacing rusted nails to refresh the deck's appearance.
Stair Anchoring
Anchoring steps costs between $15 and $40 per step. This repair helps correct wobbly steps and is an important fix for the deck's overall safety.
Pressure Washing and Staining
Pressure washing costs around $200 to $450 on average, while the cost to stain a deck is between $550 and $1,250. If you’re up for the money-saving DIY deck staining option, you’ll pay between $20 and $250 for the stain and $35 to $175 per day to rent a pressure washer.
Location
Your location can have a major impact on labor and material costs. Densely populated urban areas and places with higher costs of living will have the highest costs.
| City | Repair Cost Range |
|---|---|
| Chicago, Illinois | $1,500–$5,500 |
| Saint Louis, Missouri | $1,200–$4,800 |
| Saint Paul, Minnesota | $1,400–$5,200 |
| Houston, Texas | $1,300–$5,000 |
| Atlanta, Georgia | $1,200–$4,700 |
| Birmingham, AL | $1,100–$4,500 |
| San Jose, CA | $1,700–$6,000 |
| Fort Lauderdale, FL | $1,400–$5,300 |
Additional Costs to Consider
There’s a lot more to a deck than just the platform. Here are other additional costs to keep in mind when getting bids for your deck repair.
Railing Replacement
Replacing your deck railing can cost anywhere between $35 and $210 per linear foot. Railings are essential safety features for raised decks, and they’re also nice to have on ground-level or floating decks to prevent tripping hazards. Your final cost depends on the type of material you choose for the railing. Below are the average costs you’ll pay for these common building materials:
| Deck Railing Material | Average Cost (Per Linear Foot) |
|---|---|
| Wood | $40–$60 |
| Metal | $55–$85 |
| Composite | $80–$165 |
| Glass | $140–$210 |
| Cable | $115–$175 |
Permits
While you won’t likely need a permit for a minor repair, you may need to invest an extra $225 to $500 to cover permit fees for a new build. Deck size and elevation often affect the cost. Not all states require permits, but many of them do, so be sure to double-check or consult your contractor before starting the project.
Time of Year
If you’re seeking professional deck repairs during the busiest times of the year—from late spring through early fall—expect to pay a premium cost due to the extra demand. Putting off cosmetic repairs can save you a lot in this area, but if you’re in need of a structural repair that impacts your deck’s safety, it’s best to get it done right away.
Prep Work
If you’re having a significant repair done, such as resurfacing, restaining, or refurbishing, there may be extra costs for the prep work involved. This covers tasks like power washing, staining, sanding, and paint stripping.
Demolition
Demolishing an old deck costs about between $5 and $15 per square foot. This includes removing the old materials and the demolition itself. However, disposing of the materials yourself can help cut costs.
Site Evaluation
If you need a major repair or rebuild, your contractor may need to perform a site evaluation before taking on the project. Many contractors waive this fee if you choose to hire them for the job, and others may offer a free quote. Always ask your pro during the initial phone call to avoid surprise fees.
Sealing and Staining
The average cost to stain a deck professionally is between $550 and $1,250. Whether hiring out or DIYing, always follow up with a clear sealant for added protection. Be sure to stain and reseal your deck every two to three years.
Customizations
Going against the grain of a standard deck build will result in higher labor and material costs. Before you commit, be sure to check out portfolios and credentials for multiple contractors and request custom quotes to determine who offers the best bang for your buck.
Disposal
If a significant amount of materials need to be hauled away, disposal may be more expensive. Again, you might save money in this area if you’re willing to haul and dispose of the materials yourself.
Insurance
Homeowners insurance may not cover all issues related to your deck, such as wear and tear or specific types of damage. You might want to consider purchasing a deck insurance policy, usually offered by the builder, to make sure repairs are covered and your investment is protected.
When to Repair vs. Replace Your Deck
Building a deck is a worthwhile home improvement project that's highly likely to offer you an impressive return on investment. Remodeling by JLC's 2023 Cost Value Report found that wooden decks offer a 52.4% ROI on average, and composite decks offer a 39.8% ROI nationally.
While it’s a great idea to repair rather than replace a deck when possible, there are some instances when it’s better to start fresh. Unfortunately, if your deck is in poor shape, your best option may be to tear it down and rebuild. Here are some key signs that it’s time to budget for deck replacement costs.
| When to Repair Your Deck | When to Replace Your Deck |
|---|---|
| Minor damage, like small cracks | Significant damage, like large holes and split boards |
| Mold on the exterior that hasn’t permeated the interior | Extensive termite or mold damage |
| Popped nails or screws | Massive amounts of rotting wood |
| A build-up of dirt and grime | The overall structure sways |
| Loose railing | Frequent and high repair costs |
| It’s in need of a maintenance visit | It’s older than the projected lifespan |
DIY vs. Hiring a Deck Repair Contractor
The cost of supplies for DIY deck repairs ranges from $10 to $50 for simple projects like replacing a few broken boards, strengthening wobbly posts, or replacing nails, all of which can be done in a few hours.
Replacing decking boards can cost $3 to $45 per square foot for materials while replacing railings costs $35 to $210 per linear foot. Both projects will likely take several days to complete and require carpentry expertise. Hiring a local deck contractor will increase the total cost by $100 to $500, as you’ll have to pay for labor.
If you’re handy and have experience with carpentry, DIY repairs can save you money. However, working with a licensed pro can help you ensure that the project is done correctly and avoid the need for additional repairs in the future.
How to Save on the Costs of Repairing a Deck
To offset the cost of professional labor, you can minimize your overall deck repair costs by buying the decking materials yourself and even completing some repairs. Here are some approaches for saving on repair costs:
Ask your contractor for a complete list of needed materials, then purchase them yourself from your local hardware store.
DIY certain minor repairs, such as fixing popped nails, cleaning and sealing, and filling in cracks with composite.
Consider hiring a handyperson instead of a carpenter or deck company for minor repairs.
After repairs are made, dispose of leftover materials yourself.
Resurface your deck every two to three years or as needed to keep it looking fresh and lengthen its life span.

Frequently Asked Questions
In most cases, repairing a deck costs much less than replacing it. Deck repairs cost around $2,000 on average, while the cost of deck replacement is at least $7,900. Repairing involves fixing issues like loose boards or small cracks, which requires less material and labor. If the deck has extensive damage, though, the cost of repairs can add up quickly, and it may be more cost-effective to replace the deck entirely.
Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.
For the longest-lasting deck, consider composite and ipe hardwoods. Composite decks are known for their durability and long life span of 30 years or more. They’re more budget-friendly than ipe hardwood decks, but ipe wood lasts 75 years or longer with proper maintenance. Regardless of which material you choose, regular cleaning and sealing (if necessary) will help you get the most out of your deck.
Replacing an old or failing deck is a great way to increase your home’s value and improve its appeal to potential buyers. However, it’s important to weigh the pros and cons and consider timing. A new or replaced deck will return about 50% to 65% of its cost in home value when it comes time to sell. If you’re planning on selling your home in the short term, you may be better off just doing minor repairs and cleaning and staining your deck to increase its visual appeal.
