Pergola FAQs

  • A DIY wooden pergola costs $200 to $500 minimum to build a lean-to model from standard plywood that attaches to the home. Prices increase for sizes bigger than 10’ to 16’ long with 4 pillars and high-quality wood types.

How much does Home Depot charge to install pergola?

Home Depot pergola installation costs $5,800 to $7,200 on average for a wood design up to 12’x12’. This price includes all materials and installation labor.

Does a pergola add value to a home?

A pergola adds the most value to a home in a warm climate on a deck or stone patio. A well-maintained pergola increases curb appeal and may help sell the home faster.

What is a pergola used for, and is it worth it?

A pergola is used for creating a partially shaded walkway or sitting area outdoors while still allowing enough sunlight to fill the space. However, pergolas don’t provide full shade unless they are louvered models.

A pergola is worth it for these benefits:

  • Creating more space for plants with climbing vines

  • Increasing outdoor privacy (if screens are included)

  • Improving curb appeal

  • Adding a lounge area outdoors with a retractable shade
