Deck a little worse for wear, and in need of repair?
Leave this job to a top-rated local pro.
A deck should be a comfortable space to enjoy those summer evenings with family and friends, not a squeaky or unstable surface. If it seems like the deck is sagging in the center, the boards are uneven, or it’s looking rather unkempt overall, it’s probably time for the homeowner to consider repairing it. The amount of repair a deck needs will be a significant factor in deck repair cost.
According to Angi and HomeAdvisor, the average cost can be as little as $859 or as high as $3,321. Most homeowners spend around $2,019 to repair a deck. Aside from the amount of repair needed, it’s also important for homeowners to take into consideration the overall deck size, the deck material, any customizations, and the cost of labor. These and other factors are explained in more detail below.
Key Cost Factors
Decks come in all shapes and sizes, which is why the price range for deck repairs is so wide. The size, materials, labor, delivery fees, extent of the repair, and even location will affect the cost to repair a deck. In some cases, it may be necessary for the homeowner to have the deck entirely replaced.
Deck Size and Material
Smaller decks that measure 8 feet by 8 feet are easier and cheaper to repair or replace than larger 15-foot by 20-foot decks. The first question a deck repair pro asks will likely be about the size of the deck and then the materials, so it’s a good idea for the homeowner to have this information handy. On average, homeowners will pay between $10 and $55 per square foot for deck repair costs.
The material of the deck will also affect the price, since some materials are much more expensive than others; an average range is $3 to $45 per square foot. Many homeowners prefer cedar planks, which are cheaper and fairly durable. Cedar deck repair costs $25 to $55 per square foot. Recycled and composite decking cost more but are able to resist weathering and last longer. Composite deck repair costs $12 to $45 per square foot. The best decking material for a home will depend on the homeowner’s needs and budget. The graphic below shows the average costs for deck repair for different deck materials.
Labor and Permits
Labor will make up a portion of the cost to replace a deck or repair it, and the cost depends on current market rates and the length of time it will take to repair the deck. Usually, deck repair pros charge $100 to $500 for labor, but this cost could increase for a deck replacement. Homeowners can look up “deck repair contractors near me” to get a sense of local prices.
Permits aren’t typically needed to repair decking, especially if the repairs are minor. However, if significant changes will be made, such as increasing the deck size or upgrading it to add utilities for an outdoor kitchen, the homeowner or the contractor will need to inquire with local authorities about permits. Permit costs typically fall in the range of $225 to $500.
Delivery Fees
If the deck is in need of significant repair, a lot of materials may need to be delivered to the house. Delivery fees could run at least $50. Some deck repair companies will include this in their total prices, or this could be a separate fee if the lumber company delivers the wood directly.
Damage and Repair Type
Some deck repairs are as simple as sanding and staining to restore a weathered deck. Other times, homeowners might need to factor in the cost to replace deck boards if they are warped or damaged. The most expensive deck repairs will involve repairing the joists or the deck’s foundation. In this case, it’s difficult for a homeowner to know how to redo a deck for cheap, but it’s also worth having it done properly to ensure safety down the road. Most deck joists need to be inspected after 10 years. The table below shows the average repair cost by the type of deck damage.
| Damage Type | Cost |
| Cracks | $150 to $500 |
| Creaky boards | $150 to $600 |
| Holes | $150 to $500 |
| Missing nails | $100 to $200 |
| Mold | $200 to $600 |
| Rot | $300 to $5,000 |
| Sagging | $750 to $10,000 |
| Screws popping out | $100 to $200 |
| Termite damage | $500 to $10,000 |
| Wobbly stairs | $200 to $2,000 |
Time of Year
It’s common for homeowners to search for “deck repair near me” in late winter or early spring as they look forward to spending more time outdoors. But this is usually the most expensive time of year to do deck repairs, since there is high demand to get decks in working order. Prices may be cheaper in the late summer into early winter when the need for repairs isn’t as high.

Geographic Location
While budgeting for deck repair costs, homeowners will want to consider location. The cost in urban areas tends to be higher for construction projects than in rural or suburban areas. It’s also not uncommon for homeowners to see increased prices in areas with a lot of residential construction that puts more demand on resources and laborers.
Additional Costs and Considerations
After having a deck contractor review the current state of the deck, homeowners will have a better idea about any additional costs for their project. Deck repair contractors can help determine whether repair or replacement is best, what prep work is involved, any demolition costs, and other considerations. The following are factors that may not be accounted for by a deck repair cost calculator.
Repair vs. Replacement
Repairing a deck can be a simple process if all that’s needed is a little staining and a new deck board or two. On the other hand, it can grow into a complex project with new stairs, railings, joists, and additional customizations. New materials will always increase the price, especially if any materials are being upgraded simultaneously. But the refreshed deck might be a nice treat to enjoy. Homeowners will need to decide based on these costs whether they want to repair or replace the deck. They can expect to pay between $20 and $62 per square foot for materials to replace the same footprint. Increasing the size of the deck can cost more. Overall, replacing the deck can cost anywhere from $6,000 to $18,600.
Prep Work
A deck pro will be able to estimate how much prep work is needed to start the project. For refinishing, the deck will need to be power-washed and nearby items will need to be removed or covered for protection. Power-washing a deck costs about $100 to $200 on average. But if a lot of the damaged deck will be removed, then the contractor will need more room to work as they remove damaged materials and haul them away. This will involve clearing a larger area surrounding the deck. Removal costs $5 to $10 per square foot. The most expensive prep work is leveling the ground around the deck, which can cost $800 to $4,000.
Demolition Costs
Deck demolition is sometimes the best route when homeowners are dealing with a severely damaged or neglected deck. This usually involves removing all the old materials and even putting in new joists, as they have probably outlived their prime. Homeowners can expect to pay $5 to $15 per square foot for deck demolition and removal.
Site Evaluation
Professionals will often need to get the lay of the land before work can start on a deck repair project. Prices can vary, but some contractors may not charge for site evaluation or will include it in the overall repair cost.

Customization
Sometimes it’s worth homeowners considering the cost of any customizations to upgrade the deck while it’s being repaired. This could include a wide range of items and conveniences: misters, built-in benches, wider stairs, pergola, kitchen, fireplace, or heaters. Adding a kitchen would significantly increase costs, and anything that requires electricity will require the help of an electrician. Adding elements that are not integral to the deck, such as furniture or the best deck boxes, will not be reflected in the deck repair cost but may come into play in the future.
Disposal Costs
Some companies will charge for disposing of old materials, especially if the project was a full demolition. This cost could run as high as $500, but it’s best for a homeowner to ask the deck contractor specifically, even if there’s only a small amount of deck waste.
Types of Deck Repair
A deck installer can provide an accurate assessment of the deck’s condition so it’s clear exactly what needs attention. Homeowners can expect the following areas to be assessed for repair or replacement.
| Repair Type | Cost |
| Board replacement | $500 to $4,000 |
| Flashing repair | $15 to $30 per linear foot |
| Joist repair | $100 to $300 per joist |
| Mildew repair | $0.25 to $1.50 per square foot |
| Mold and rot repair or removal | $200 to $500 |
| Pest control | $200 to $600 |
| Pressure washing | $200 to $400 |
| Refurbishing | $100 to $2,000 |
| Resurfacing | $15 to $50 per square foot |
| Sealing or staining | $540 to $1,250 |
| Stair anchoring | $100 to $300 |
| Stair repair | $15 to $50 per step |
| Railing repair | $35 to $210 per linear foot |
Board Replacement
Homeowners who have spotted a couple of damaged boards might have wondered how to replace deck boards. Sometimes they can be repaired with some sanding and epoxy to fill cracks and holes, but other times they’ll need to be replaced. This can cost between $500 to $4,000.
Flashing Repair
Like the flashing found on a roof or around windows, deck flashing is a metal material that prevents water from seeping in the space where deck materials meet the home. Damaged flashing can quickly lead to mold and water damage, and flashing repair costs $15 to $30 per linear foot.
Joist Repair
Joists that are damaged or have started to rot cost $100 to $300 per joist to repair. Most often this is done by placing a sister joist alongside the original to reinforce it. Otherwise the joist may need to be partially or completely replaced.
Mildew Repairs
Mildew removal is a fairly simple repair that only requires a thorough power wash. Some homeowners feel comfortable renting a power washer and doing this themselves. Rental costs are around $40 to $75 per day and an additional $10 to $30 for the best deck cleaner (or the cost of materials for a homemade deck cleaner). Alternatively, a professional charges $0.25 to $1.50 per square foot to power-wash a deck.
Mold and Rot Repair or Removal
Mold removal could involve a thorough power-washing or full replacement of the affected area. One option is to hire a professional, or some homeowners rent the equipment themselves and purchase cleaning supplies. Replacing the moldy area will be more labor-intensive, especially if the mold has affected any framework. A professional will charge between $200 and $500 for these repairs.
Pest Control
If there’s a pest infestation, it’s important for the homeowner to have a pest control pro inspect the deck. They may charge $65 to $100 for the inspection and report, but the repairs for damaged wood and joists often cost between $200 and $600.
Pressure Washing
Power or pressure washing usually costs a flat fee of $200 to $400. Not washing a deck before staining it is one of the most common deck staining mistakes DIYers make. Washing is crucial because it provides a smooth, clean surface for the stain, which allows it to last longer for improved deck waterproofing.
Refurbishing
Refurbishing a deck is more of a face-lift. Homeowners can expect to pay around $100 to $2,000 for a deck refurbishment, which can encompass the cost to paint the deck, sand and stain areas that need a refresh, replace worn-out nails, or tidy up its overall appearance with a little cleaning.
Resurfacing
Resurfacing a deck is like giving it a complete makeover. A deck repair handyman will replace the major pieces like deck boards, stairs, and railings but leave the base intact. The deck will appear brand new and refreshed. This often costs $15 to $50 per square foot.
Sealing or Staining
Sealing or staining a deck is part of proper annual deck maintenance, which is important for making sure the deck lasts for many years. A deck contractor can handle deck repair and staining. The cost to stain a deck is $540 to $1,250, and sealing costs are about the same. Some of the best deck paints can also provide a protective layer when applied.
Stair Anchoring and Repair
Wobbly stairs are a danger for anyone using them, so it’s important to get them repaired and anchored quickly. Stair repairs could cost $15 to $50 per step or $100 to $300 overall to anchor the steps.
Railing Repair
Railings take longer to build, so they’re a major part of a deck cost estimator when homeowners are building a new deck. Repairing railings can become costly depending on the type of railings and the extent of the damage. Homeowners can expect to spend
