How Much Does Deck Repair or Replacement Cost in Phoenix, Arizona? [2025 Data]

The average deck repair cost in Phoenix is $1,131, with most people spending between $519 and $1,743. Your project total ultimately hinges on the type and severity of the damage to your deck, but your deck’s size and material also play a part. This guide breaks down these factors to help you budget for deck repairs in Arizona’s capital.

Deck Repair Cost Factors

The cost of repairing a deck in Phoenix, AZ, depends on several key factors, including the size of the problem area and your decking material. Here’s how.

Deck Size

Larger decks carry higher material costs and greater labor costs. To get an idea of repair costs, you can inspect your deck and measure the problem areas. The materials for deck repair cost between $3 and $45 per square foot, with the type of decking also influencing the cost.  Size also impacts the cost of rebuilding a deck from scratch. In Phoenix, the average cost to build a new deck ranges between $2,293 and $9,171, or $15 to $31 per square foot.

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’ll need to replace certain types more often than others.

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.

Railing Replacement

In Phoenix, replacing your deck railing costs $18 to $107 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 accidents. Your final cost depends on the material you choose for the railing. 

Demolition

Demolishing an old deck costs $5 to $15 per square foot. This includes removing the old materials and the demolition itself. However, disposing of the materials yourself can cut costs.  

Sealing and Staining

The average cost to stain a deck professionally in Phoenix is between $280 and $637. 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.

When to Repair vs. Replace Your Deck

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 is to tear it down and rebuild. Here are some key signs that it’s time to budget for deck replacement costs.

Deck Repair Pro Costs

Some deck repair jobs will have additional costs, including professional labor and permits. Here’s how to prepare for those expenses.

Licensing

If your deck only needs minor repairs (like removing mildew or replacing loose nails), you can tackle them yourself or hire a deck pro in Phoenix. In Arizona, any business that builds, alters, or repairs part of a residential structure must have a state-issued contractor’s license. 

Before hiring a pro, you can look up the status of their license on the Arizona Registrar of Contractors (ROC) website. 

Permits

The city of Phoenix requires a permit for certain deck repairs and replacements, depending on the specifics of the job, as well as the deck’s height and location. If you’re unsure whether you need a permit, ask your contractor before any repair work begins. They’ll explain which permits they plan to pull for your project (if any) and walk you through the estimated permit costs.

Sales Tax

Don’t forget about Phoenix’s 9.1% sales tax when calculating your deck repair costs. As an example, if your project subtotal is $1,100, sales tax would add $100 to your bill.

Does Deck Repair Increase Home Value?

Data from the Journal of Light Construction (JLC) shows just how valuable decks are in the Valley of the Sun. According to the JLC’s Cost Versus Value Report, homeowners in Phoenix recoup 90.2% of their costs after installing a wood deck. They also get 87.6% of their investment back after adding a composite deck.

There are plenty of opportunities throughout the year to enjoy Phoenix’s desert climate—and with a deck, you can do that from the comfort of home. If you sell your home, buyers will appreciate that, too. So if your deck needs repairs, you should take care of them before putting your house on the market.
