What Is the Cheapest Type of Pergola?
Quick Answer
The cheapest professionally installed pergola is a basic pressure-treated pine or cedar attached pergola in a standard size (12×12 or 12×16), which starts around $7,000-$10,000 installed in the Oswego area. DIY pergola kits from home improvement stores start at $1,500-$4,000 for materials, but professional installation on a concrete footing adds $3,000-$6,000 to that. Budget options exist – but be clear on what you’re giving up at the lower price point, and be cautious of quotes that seem too low.
Detailed Explanation
Budget is a real factor in pergola decisions, and there’s no shame in wanting to find the most cost-effective option. Here’s an honest breakdown of budget approaches – and the trade-offs that come with each.
Least Expensive: Pressure-Treated Pine, Attached, Basic Design
The most budget-friendly professionally installed pergola in our area is a pressure-treated pine attached pergola in a standard size, built to a basic design with minimal decorative detail.
Why each of these choices reduces cost:
Pressure-treated pine over cedar: PT pine is less expensive per board foot than cedar. The visual trade-off is that PT pine requires more finishing work to look attractive and doesn’t have cedar’s natural warm appearance. For homeowners willing to paint or stain the structure, PT pine is a practical cost saver.
Attached over freestanding: An attached pergola uses the house as one support, requiring only two yard-side post footings rather than four. Fewer footings means less excavation, less concrete, and less labor.
Standard design: Decorative rafter tails, shaped beam ends, and lattice infill panels all add cost. A square-cut simple design is the most budget-efficient.
A basic attached 12×12 pergola in pressure-treated pine, professionally installed with concrete footings and a permit, runs roughly $7,000-$10,000 in the Oswego and Fox Valley area. A cedar version of the same structure runs $8,000-$12,000.
DIY Kits: Lower Material Cost, But Not Zero
Big-box stores and online retailers sell pergola kits – pre-cut, pre-drilled component sets that homeowners assemble themselves. Kit prices range from $1,500 for small vinyl or metal kits to $6,000+ for premium cedar or aluminum kits.
The honest assessment of DIY kits in Illinois:
What you save: Labor for the assembly portion of the work.
What you still need: Concrete footings (excavation and pouring is heavy work requiring equipment), post base hardware, permit fees, and potentially professional help for the footing work.
What you give up: Engineered specifications that match your municipality’s permit requirements, a warranty on installation workmanship, and the assurance that footings are correct for Illinois frost depth.
The real risk: A DIY pergola with inadequate footings fails in Illinois winters. The $2,000 you saved on labor becomes a $5,000 repair or replacement when frost heave racks the structure after three winters.
If you’re handy, motivated, and willing to research the permit requirements in your municipality, a quality kit from a reputable manufacturer can be a legitimate option. If you’re uncertain about any of those elements, the cost savings may not be worth the risk.
Mid-Range Budget: Get More for Not Much More
The price gap between a basic cedar pergola ($8,000-$12,000) and a mid-range cedar or aluminum pergola ($14,000-$20,000) is real – but the value increase in that gap is significant. At the mid-range:
- You can size up (12×16 or 14×16 vs. 12×12)
- You can add basic lighting rough-in
- You can consider aluminum with its zero-maintenance advantage
- You can include minor decorative details that make the structure look purpose-built
For many homeowners, stretching from budget to mid-range delivers meaningfully more satisfaction.
What to Be Cautious About
Unusually low quotes: If a contractor quotes a 12×16 pergola for $4,000-$5,000 with permits and footings, the math doesn’t work at legitimate material and labor costs. Ask what’s included. Missing permits and improper footings are the most common corners cut in low bids.
Online retailers promising low installed prices: Some online pergola companies advertise low prices that cover only the kit – not footings, permits, or installation. Read the fine print carefully.
Skipping permits to save money: Permit fees are $150-$600 in our area – a small fraction of project cost. Skipping permits creates home sale problems and fine exposure worth far more than the fee.

Important Considerations
The cheapest pergola that lasts is better than the cheapest pergola period. A $7,000 pergola that needs major repairs in year five or replacement in year ten isn’t cheaper than a $12,000 pergola that runs 25+ years without structural issues.
Maintenance is a real cost. Wood pergolas require re-sealing every 2-4 years. Budget $200-$600 per maintenance cycle for materials and potentially labor if you hire out. This is a real cost of wood ownership that some budget comparisons omit.
