If you are planning a new deck for your Aurora home in 2026, you have likely noticed that the price gap between wood and composite has narrowed significantly. Five years ago, composite decking cost nearly double what pressure treated pine did. Today, the gap in Aurora is closer to 30 to 50 percent, and when you factor in the cost of staining and sealing a wood deck every two years, composite is often the more affordable choice over a decade. This shift is why more Aurora homeowners are choosing Composite Decks in 2026, and this guide will give you the real numbers, the hidden costs, and the exact factors that determine what you will pay.
Average Composite Deck Installation Costs in Aurora, IL (2026 Breakdown)
In the Aurora market, composite deck installation typically runs between $40 and $60 per square foot for a full turnkey project. This includes the substructure, decking boards, railing, stairs, and labor. For a 300 square foot deck, that means a total cost of roughly $12,000 to $18,000. A larger 500 square foot deck with multiple levels and custom railing can run $25,000 to $35,000.
The material itself makes up about half the total cost. A mid grade composite board like Trex Select or TimberTech Earthwood runs $4 to $7 per linear foot. Premium products with capping on all four sides, like Trex Transcend or TimberTech Pro, cost $7 to $11 per linear foot. The substructure, typically pressure treated lumber or steel, adds another $5 to $8 per square foot. Railing is a major line item: a basic aluminum railing system costs $30 to $50 per linear foot installed, while cable or glass railing can push that to $75 or more.
Do not forget the hidden costs. Permits in Aurora run $150 to $400 depending on project size. If your yard has difficult access or requires demolition of an existing deck, add $500 to $2,000. And if you want integrated lighting, built in seating, or a pergola on top, those are separate line items. A good rule of thumb: budget 15 to 20 percent above the base quote for surprises, especially if your house was built before 1980 and the foundation or ledger board attachment could complicate things.
4 Key Factors That Affect Your Composite Deck Price in Aurora
1. Deck Size and Complexity
Square footage is the obvious driver, but shape matters too. A simple rectangle with stairs on one side is the cheapest shape to build. Add a curve, a multi level design, or a wrap around corner, and you are paying for more labor, more cuts, and more waste. Every 90 degree turn and change in elevation adds complexity.
Height above grade also matters. A deck less than 30 inches off the ground requires fewer footings and simpler bracing. A second story deck 10 feet up needs deeper footings, more structural support, and taller railings that meet code. In Aurora, the frost line is 36 inches, so any footing must go that deep. That means excavation costs, concrete, and inspection fees.
2. Composite Material Grade
Not all composite is the same. Entry level composite is often hollow or has a thin cap that can fade and stain faster. Mid grade boards have a thicker cap and better color retention. Premium boards have capping on all four sides, which prevents moisture absorption from the bottom and resists mold and mildew better.
The warranty reflects the quality. Entry level products carry 10 to 15 year warranties. Premium products offer 25 to 50 year limited warranties. If you plan to stay in your Aurora home for more than a decade, the premium boards are almost always worth the extra $2 to $4 per square foot.
3. Labor Rates in the Aurora Area
Skilled deck builders in the western suburbs of Chicago charge $50 to $85 per hour per crew member. A two person crew on a 300 square foot deck will spend 80 to 120 hours total, including design, material pickup, site prep, construction, and cleanup. That puts labor at roughly $8,000 to $15,000 for the project.
Cheaper labor is out there, but be cautious. A crew charging $35 an hour may not carry proper insurance or pull permits. In Aurora, the building department requires a licensed contractor for structural work, and they check permits regularly. If you hire an unlicensed crew and they get caught, you could face fines and have to tear out the work.
4. Site Conditions and Access
If your yard is flat and open, a crew can work quickly. If you have a steep slope, retaining walls, or a fence that requires hand carrying materials 50 feet, you will pay for the extra time. Trees, utility lines, and septic systems also add constraints that increase labor time.
Burns Carpentry, a local Deck Building company serving Aurora, always does a site visit before quoting. They measure the exact access path, check for underground utilities, and assess the condition of your existing foundation if you have a ledger board attachment. This upfront assessment eliminates surprises later.
Composite vs. Wood Deck: Total Cost of Ownership Comparison
This is the question every Aurora homeowner asks. Let us run the numbers for a 300 square foot deck over 15 years, which is the realistic lifespan of a well built wood deck versus a composite deck that will last 25 to 30 years.
A pressure treated pine deck costs $20 to $30 per square foot installed, so about $6,000 to $9,000 upfront. Over 15 years, you will need to power wash and seal it every two to three years. Each sealing costs $400 to $800 in materials and labor if you hire it out, or about $100 in materials if you DIY. Total maintenance over 15 years: $2,000 to $4,000. And at year 12 to 15, you will likely need to replace some boards and repair the railing, costing another $1,500 to $3,000. Total cost of ownership: $9,500 to $16,000.
A composite deck costs $40 to $60 per square foot installed, so $12,000 to $18,000 upfront. Maintenance is basically zero: a wash with a garden hose and mild soap once a year. No staining, no sealing, no board replacement for at least 20 years. Total cost of ownership over 15 years: $12,000 to $18,000.
So the composite deck costs more upfront, but over 15 years, the difference is only $2,500 to $2,000. And you save dozens of hours of labor and the hassle of scheduling contractors every two years. If you plan to sell your home before year 10, wood might make sense. But if this is your forever home, composite is the smarter financial move.
"The math on composite only makes sense if you stay in the house long enough to avoid the major maintenance costs of wood. For most Aurora homeowners, that tipping point is year 6 to 8."
How to Get an Accurate Quote from a Local Professional Services Provider
Getting a quote for a composite deck is not as simple as calling three companies and picking the cheapest number. You need to compare apples to apples. Here is a step by step checklist to get accurate, comparable quotes from deck building companies like Burns Carpentry.
- Define your project scope before calling. Know the approximate size, shape, and height of the deck you want. Sketch it out or use a rough online tool. The more detail you give, the more accurate the quote.
- Ask for a written quote that itemizes materials, labor, and permits. If a contractor gives you a single number with no breakdown, that is a red flag. You need to see how much is for composite boards, how much for substructure, how much for railing, and how much for labor.
- Confirm that the quote includes permit fees and inspection costs. In Aurora, permits are required for any deck over 30 inches above grade or attached to the house. Some contractors quote without permits to appear cheaper, then hit you with the permit cost later.
- Ask about the warranty on workmanship. Burns Carpentry, for example, guarantees their workmanship for two years from the date of completion. The composite manufacturer warranty is separate and covers material defects. Make sure you get both in writing.
- Get references and look at recent projects. Ask for three completed projects in the Aurora area that are at least two years old. Go see them if possible. Look for signs of fading, warping, or loose railing.
- Do not pay more than 25 percent upfront. A reputable contractor will ask for a deposit to secure materials, but the balance should be due upon completion and your satisfaction. Never pay the full amount before work starts.

Their process starts with a call to discuss your vision, then a site visit where they measure, check for utilities, and talk through design options.
