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.

Generally, a patio is more accessible than a standard deck because patios are constructed at ground level. However, decks can be made accessible by adding a wheelchair-accessible ramp, a vertical lift, or a stair lift along the entry. An ADA-compliant deck ramp costs about $3,000 on average. The additional investment will provide a much friendlier experience for your guests with movement impairments.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

Yes, adding a composite deck, such as one made from Trex, can significantly increase your home's value. It is a valuable home renovation for recouping costs, with some estimates for return on investment (ROI) ranging between 60% and 70%. More recently, Remodeling's 2024 Cost vs. Value Report suggests a deck addition has an ROI of 82.9%, with an average resale value of nearly $14,600. A new deck makes your yard more functional, enhances the landscape's aesthetic, and can entice prospective buyers. The investment may have a higher return if the deck adds usable square footage to the property.
