Pergola Installation Cost

A pergola adds partial shade and a defined outdoor room over a patio or deck without the cost of a solid roof. What you pay depends mainly on the material, the footprint, and whether a crew assembles a prefab kit or builds a custom structure on site.

This guide covers installed costs by size and material, a line-item estimate, and how to save. For a fully motorized louvered roof, see our StruXure pergola cost guide; if you want walls or screens, compare patio enclosure costs.

Pergola cost by size

Cost breakdown: materials, labor, permits and extras

Line-item estimate for a 12x12-ft prefab pergola kit (wood, vinyl or aluminum) professionally assembled on an existing patio. Ranges are national, as of October 8, 2026.

A custom-built wood pergola of the same size costs about two to three times as much, mostly because of on-site carpentry.

What affects the price

• Material (wood, vinyl, aluminum). Aluminum and vinyl cost about $10–$30 per sq. ft. in materials, pine $20–$40, cedar $25–$40 and redwood $40–$50. Wood needs staining or sealing every few years (about $2–$5 per sq. ft.), while vinyl and aluminum need little upkeep.
• Size. Price scales with footprint: Angi reports about $3,000–$6,000 for a 10x10 pergola and $4,300–$8,600 for 12x12. Larger spans may need thicker beams or extra posts.
• DIY kit or custom. A prefab kit installed by a pro costs about $10–$40 per sq. ft., while a custom pergola built on site runs $30–$65 per sq. ft., roughly two to three times the kit price. Kit assembly labor typically runs $600–$1,500; custom builds $2,000–$7,000.
• Permits. Many towns don't require a permit for a freestanding pergola, but some do, especially for attached or larger structures. When required, permits cost about $50–$500, with many in the $60–$150 range.

Ways to save

• Choose a prefab kit instead of a custom build; installed kits cost roughly a half to a third as much as custom pergolas.
• Assemble a kit yourself if you are handy. Angi estimates DIY saves about $500–$1,000 in labor, though large pergolas still need two or more people.
• Build on an existing patio or deck so you don't pay $600–$4,300 for a new slab or deck base.
• Pick aluminum or vinyl if you want to skip the cost of staining or painting a wood pergola every few years.
• Get at least three quotes and confirm whether anchoring, footings, staining and permit fees are included.

How to get an accurate quote

Request at least three written quotes from licensed, insured contractors. Share:

• The pergola's size, the surface it will sit on (patio, deck, grass) and whether it attaches to the house.
• Your preferred material and style, or the exact kit model if you already chose one.
• Extras such as a retractable canopy, lighting, an outdoor outlet or privacy screens.
• Ask how posts will be anchored or footed, who handles permits, and what warranty covers the work.

FAQ

Does a pergola need footings?

Most pergolas need to be securely anchored, either to concrete footings in the ground or with brackets to an existing slab or deck framing. Heavier roofs, such as louvered aluminum systems, typically require concrete footings at each post.

How long does it take to install a pergola?

A prefab kit takes about 1–4 hours of assembly according to Angi, while a custom pergola takes about 8–16 hours of work, plus time for footings to cure.

How much does it cost to add a roof or canopy to a pergola?

A retractable fabric canopy adds about $4–$10 per sq. ft., while a louvered roof costs $45–$125 per sq. ft. or more. Lighting fixtures run about $80–$300 each, and an outdoor outlet $180–$350.
