A standard 12x12 pergola runs $2,000 in pressure-treated wood up to $20,000 in fiberglass, with aluminum and vinyl priced at $5,000 to $12,000. Material choice drives most of that spread, and a factory kit typically costs 40 to 50 percent less than a custom build. Aluminum is the smart middle pick: it holds its finish for decades with almost no upkeep.
How much does each pergola material cost?
Frame material accounts for most of the price gap between a budget pergola and a luxury one.
| Material | Cost (12x12 ft) | Maintenance |
|---|---|---|
| Pressure-treated wood | $2,000-$5,000 | High - reseal every 2-3 years |
| Cedar | $4,000-$9,000 | Moderate - stains and ages well |
| Vinyl | $5,000-$12,000 | Low - won't rot or rust |
| Aluminum | $5,000-$12,000 | Very low - holds factory finish for decades |
| Fiberglass | $8,000-$20,000 | Very low - spans long distances without sagging |
Pine twists and grays unless you seal it regularly, while cedar's natural rot resistance and warm grain justify the step up. Aluminum spans wide openings without bulky posts, keeping sightlines clean. Fiberglass stretches a 20-foot beam without sagging and is the lightest material relative to its strength, but that performance comes at a per-square-foot premium best reserved for long, unbroken spans.
Material also limits how you dress the structure. Wood and aluminum both hold screw-in hooks for string lights, hanging plants, and retractable shade, while vinyl can crack under an over-driven fastener. Climbing vines like wisteria look striking on sturdy cedar, but their weight and moisture can shorten the life of a lighter frame, so match the material to the look you want five years out.
What does a typical pergola budget include?
A 12x12 pergola is the most quoted size, and breaking the cost into parts clarifies any estimate:
| Line item | Cost |
|---|---|
| Structure and posts | $2,500-$6,000 |
| Footings and anchoring | $400-$1,200 |
| Delivery/crane or lift fees | $200-$800 |
| Assembly labor (1-2 days) | $1,000-$3,000 |
| Permit and inspection | $150-$500 |
Fully installed, a 12x12 aluminum pergola runs roughly $5,000 to $9,000, with cedar a bit lower and fiberglass noticeably higher. A larger 16x20 structure climbs to $9,000-$15,000 since material and labor scale with span and post count. Attached designs add a ledger board and flashing, raising both cost and the stakes on correct waterproofing.
Add-ons move the total quickly:
- Retractable canopy: $500-$1,500
- Integrated LED lighting: $300-$1,200
- Privacy screen wall: $800-$2,500
Decide on these before signing a contract; adding them later usually costs more.
What mistakes drive up pergola costs?
- Sizing the kit to the yard, not the furniture. Measure your seating footprint and add at least 2 feet of overhang per side.
- Skipping proper footings. Anchor every post to concrete or a rated surface mount, especially in open, windy sites.
- Underestimating wood upkeep. A $3,000 cedar bargain still costs a weekend and about $150 in stain every couple of years.
- Ignoring HOA rules. Some associations cap height or dictate colors, which can stall a project for weeks.
- Sequencing the build wrong. Set posts before a patio goes in, and rough in utilities early if you're adding an outdoor kitchen underneath.
- Oversizing the structure. A pergola that dwarfs a modest yard swallows the space it was meant to define.

Frequently Asked Questions
What is the cheapest pergola material?
Pressure-treated pine is cheapest at $2,000 to $5,000 installed for a standard size. It carries the lowest sticker price but the highest long-term upkeep, needing resealing every two to three years. Cedar costs more upfront but ages with far less maintenance effort.
Is a pergola kit worth it over a custom build?
For standard rectangular sizes, a kit can save 40 to 50 percent and still look polished once assembled. Custom builds make sense only for unusual spans, attached designs, or premium joinery. Most homeowners are well served by a quality kit.
Do I need a permit for a pergola?
Many jurisdictions require one for freestanding structures over a certain height or square footage, often around 120 square feet. Permit fees typically run $150 to $500, and an inspection confirms safe anchoring. Always check local rules before you buy.
How much does an attached pergola cost compared to freestanding?
Attached pergolas cost more than freestanding ones of the same size because they need a ledger board tied into the house and careful flashing to prevent leaks. Budget extra labor and material for that connection point. The freestanding cost ranges above still apply to the rest of the structure.
