Sound familiar?
You hired someone who sounded solid – then they changed the price, missed the start date, or disappeared after the deposit. That’s not bad luck. That’s a broken industry. Here’s what a good contractor actually looks like:

Our Services
We are experts at creating custom decks, pergolas, and gazebos that compliment your home. We have the skills to make your dream a reality and get it done efficiently without sacrificing quality. We can build with wood, composite, or pvc, depending on the type of look you want. We also specialize in working around pools and landscaping so that everything looks natural and compliments your home. We pride ourselves in building your dream project.
Composite Decks
Choose a composite deck for lasting beauty and minimal maintenance. Made from a blend of recycled wood fibers and plastic, composite decking offers the look of natural wood without the upkeep. These durable boards resist fading, staining, scratching, and mold, and won’t splinter or rot. Enjoy a barefoot-friendly surface that stays cooler in the sun and doesn’t require staining, sealing, or painting. Available in various colors and textures, composite decks provide a long-lasting, eco-friendly alternative to traditional wood. With a composite deck, you’ll spend less time on maintenance and more time enjoying your outdoor space.
Pergolas & Gazebos
Enhance your deck with our custom pergolas and gazebos. These structures add function and style to your outdoor space. Pergolas provide partial shade with an open lattice roof, perfect for plants or lighting. Gazebos offer full coverage, creating a sheltered spot for relaxation or gatherings. Built directly onto your deck, these additions define areas, improve aesthetics, and extend outdoor living. We use quality materials and skilled craftsmanship to ensure durability and seamless integration with your existing deck.

Frequently Asked Questions
Your Questions Answered
Most composite deck builds in the Fox Valley run $18,000–$32,000 for a 400–500 sq ft deck — roughly $40–$70 per square foot installed. Pricing depends on board brand (Trex, TimberTech, Azek), railing choice, added features like lighting or a pergola, and site complexity. Wood decks start lower but carry annual maintenance costs that add up fast in Illinois winters. We provide free, itemized on-site estimates — real numbers, not ballparks.
Yes — fully. DDT pulls every permit required for your project in Oswego, Aurora, Montgomery, Yorkville, Plainfield, and surrounding municipalities. We prepare the drawings, submit the application, and coordinate inspections. If you’re in an HOA, we advise on the HOA approval process, which must be completed before the village permit. You don’t deal with the paperwork.
Illinois sees 30–40 freeze-thaw cycles per year. Wood absorbs moisture that expands during freezing, causing boards to warp, crack, and rot from the inside out. Composite’s capped outer layer is waterproof and dimensionally stable — it doesn’t move with Illinois temperature swings. Maintenance drops from 40+ hours of annual staining and sealing to one power wash per year. Quality composite also carries 25-year warranties that wood simply can’t match.
From signed contract to final walk-through, most projects take 5–8 weeks. That breaks down as 2–4 weeks for permit processing in Kane or Kendall County, then 3–7 days of on-site construction depending on project size and complexity. We give you a confirmed start date when the permit clears — not a vague ‘a few weeks’ estimate.
DDT Deck Builders is based in Oswego and serves the full Fox Valley and Kane/Kendall County area: Oswego, Aurora, Montgomery, Yorkville, Plainfield, Naperville, Batavia, Geneva, and St. Charles. If you’re in Kane or Kendall County, there’s a good chance we’ve built in your subdivision. Call or request an estimate and we’ll confirm availability for your address.
Three things homeowners consistently tell us: we show up when we say we will, our price matches the quote, and we don’t disappear after the deposit. We’re family-owned, licensed, and insured with $1M liability coverage. We handle permits, HOA coordination, and inspections — not just the build. And we stand behind our work after the final walk-through. That’s the DDT Standard.
