Cost to Convert a Wood Deck to Composite

The cost to convert an old wooden deck to composite materials—such as Trex or Azek—typically ranges from $40 to $75 per square foot, depending on the size of the deck, its current condition, the complexity of the project, and your chosen options for railings and other features.

A detailed quote will factor in necessary repairs or modifications to the existing structure, the type of composite decking selected, and any upgrades you’d like to include.
