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.

It is possible to build your own deck, but it’s typically better to leave the work to a decking professional. Decks can be exceptionally complicated, especially if you want a wrap-around or second-story deck, and you don’t want to risk making an expensive or dangerous mistake. It’s usually better to hire a decking pro who can pull permits and build a structurally sound deck that will last for decades and provide the maximum return on investment.

No, you don’t need a permit to repair and replace a few boards on an existing deck. However, if you’re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor who builds decks for advice.

It depends on the type of wood. The average cost to build a deck out of pressure-treated lumber is $15 to $25 per square foot, but more affordable varieties such as bamboo and cedar cost less at around $3 to $10 per square foot. However, when comparing the cost of vinyl decking versus wood decking, it’s important to also consider ongoing maintenance costs. For example, most woods require regular sealing to keep them protected against weather and rot.
