If you are planning a deck for your Cary home in 2026, the biggest surprise might not be the cost. It might be the calendar. Between material lead times that stretched into months during the post pandemic years and a permitting process that still catches homeowners off guard, a deck project in 2026 demands more than a weekend of planning. The Deck Building timeline in Cary typically runs three to five weeks from consultation to completion, but that number hides a lot of detail. How fast it actually goes depends on when you start, what you build with, and how many rainy weekends pop up between May and October. Here is what the process really looks like, broken down phase by phase, so you know exactly what to expect.
Phase 1: Design and Permitting , How Long Does It Really Take?
Most homeowners assume the design phase is the quick part. You know what you want. You describe it to a carpenter, they sketch it up, and you pick a stain color. In reality, the design and permitting phase can eat up one to two weeks before a single board is delivered, and in Cary, the permit step is not something you want to rush.
Burns Carpentry handles the permit application for every deck project we build. That means we take your initial ideas, translate them into detailed plans that meet McHenry County building codes, and submit everything to the Cary municipal offices. The review process typically takes five to seven business days for a standard deck. If your design includes anything non standard, like a multi level structure, a built in hot tub pad, or a roofed pergola tied into the house roofline, expect closer to ten business days. We have seen permits held up because a setback measurement was off by six inches or because the planned foundation depth did not match the frost line requirement for Illinois. Those are the kinds of details a good carpenter catches before submission, not after.
Here is the insider advice most articles skip: start this conversation in late winter. If you call Burns Carpentry in January or February, we can do the site visit, nail down the design, and have your permit ready to go by early March. That puts you in line for an April build start, which is prime time in Cary. If you wait until May to call, the permit queue is longer, the weather is iffy, and you are competing with every other homeowner who wants their deck done before July 4th. The smartest move you can make for a 2026 deck is to have the permit in hand before the snow melts.
Phase 2: Material Lead Times , Wood vs. Composite in 2026
This is the phase where timelines get unpredictable. Between 2020 and 2023, lumber prices swung wildly and composite decking backorders stretched to eight or ten weeks. By 2026, the supply chain has stabilized significantly, but that does not mean every material is sitting on a shelf waiting for you.
Pressure treated wood, the standard for Wood Decks, is generally available within a few days. The catch is that lumber quality varies by season and by supplier. If you order wood in early spring, you get the freshest stock from the mills. If you order in August, you might get material that has been sitting in a humid lumberyard for months, which means more warping, more cupping, and more time spent culling bad boards. A wood deck from Burns Carpentry, built under our Essential Deck Package, uses premium grade lumber that we hand select for straightness and grain quality. That adds a small scheduling buffer because we do not accept whatever arrives on the truck. We pick the good stuff, and that takes an extra day or two.
Composite decking, like the materials used in our Preferred Composite Deck Package, has a different timeline. Most composite brands require a lead time of one to three weeks for a full deck order, depending on color availability and the manufacturer's production schedule. Certain colors are always in stock. Others, especially the trending gray tones and darker browns, may have a two week backorder. If you choose a premium composite with a capped surface for stain resistance, plan for three weeks from order to delivery. The trade off is worth it: composite never needs staining or sealing, it resists the freeze thaw cycles that Illinois winters throw at it, and it holds its color for decades. But you have to plan for the wait.
The practical takeaway: If you are building a wood deck, you can start material procurement as soon as the permit is approved. If you are building composite, place the material order the same day you submit the permit application. That way the materials arrive around the same time the permit clears, and you do not lose a week waiting for deck boards to ship.
Phase 3: Construction , From Demo to Deck in Weeks
Once the permit is approved and the materials are on site, the actual construction moves fast. A typical deck project from Burns Carpentry takes one to two weeks of active build time, depending on the size and complexity of the design. Here is what that timeline looks like broken down by day.
Day 1: Site preparation and demolition. We clear the area, remove any existing deck structure, and excavate for footings. If you have a concrete patio that needs to come out, add a day. If the site is a clean grass lawn with no old structure, we can pour footings on day one.
Days 2 to 4: Framing and structural work. This is where the deck takes shape. We set the posts, install the beams, and lay out the joists. For a standard 12 by 16 foot deck, framing takes about two full days. For larger or multi level decks, expect three to four days. During this phase, the crew is working with the local frost depth requirements and making sure every connection meets code. Burns Carpentry builds every deck with superior structural integrity, meaning joist hangers, lag bolts, and post anchors are all specified for Illinois wind and snow loads, not the minimum code standard.
Days 5 to 7: Decking and railings. The deck boards go down next. For a wood deck, this includes staining or sealing if you choose that finish. For composite, the boards are installed with hidden fasteners for a clean look. Railings, stairs, and any built in features like planter boxes or bench seating get installed in this window.
Days 8 to 10: Final details and cleanup. We install trim boards, skirt the deck if requested, add post caps, and do a full walkthrough with you. Every fastener gets checked. Every board gets inspected for defects. Then we clean the site, haul away debris, and hand you the keys to your new outdoor space.
The total construction window for most decks is about two weeks. Smaller decks under 200 square feet can finish in five to seven days. Larger projects with pergolas, outdoor kitchens, or integrated lighting may stretch to three weeks. Burns Carpentry's Premium Outdoor Living Package includes all of those extras, and we schedule accordingly so nothing feels rushed.
Phase 4: Final Inspection and Weather Delays , Planning for the Unexpected
Here is the phase that frustrates more homeowners than any other. The deck is built. It looks perfect. You want to put furniture on it and invite people over. But you cannot use it until the final inspection is signed off by the Cary building department.
Final inspections are typically scheduled within two to five business days of completion. The inspector checks footing depth, ledger board attachment, railing height and spacing, stair rise and run, and fastening schedules. If everything passes, you get your certificate of occupancy and the deck is officially yours to use. If something needs correcting, the crew comes back, fixes it, and schedules a re inspection. Re inspections usually happen within two business days.
Weather is the other wild card. Illinois spring and summer are unpredictable. A week of steady rain can push a two week build into three weeks. High winds can shut down a day of framing. Extreme heat can slow down concrete curing for footings. The best contractors build weather buffers into their schedules. When we quote a three to five week timeline at Burns Carpentry, that range includes weather delays. We do not promise two weeks and then blame the rain. We tell you three to five weeks and deliver on that promise.
What you can do to avoid delays: Accept that May and June are the rainiest months in Illinois. If you want the most predictable weather window, schedule your build for July or August. Yes, it is hot. But the rain risk drops significantly, and the crew can work straight through without losing days to storms. Also, make sure your yard is accessible. If the crew has to walk materials through a muddy side yard because your fence gate is too narrow, that adds time. Clear a path. Move the patio furniture. Trim overhanging branches. Every hour the crew spends moving obstacles is an hour not spent building your deck.
Frequently Asked Questions
Do I need a permit for a deck in Cary Illinois?
Yes. Any deck that is attached to the house, elevated more than 12 inches off the ground, or over a certain square footage requires a building permit in Cary. Burns Carpentry handles the entire permit process for you, including the application, plan submission, and inspection scheduling, so you never have to visit the village office.
How much does a deck cost in Cary in 2026?
The cost varies by material and size. A basic wood deck under the Essential Deck Package typically runs $25 to $35 per square foot installed. A composite deck under the Preferred Composite Deck Package runs $40 to $55 per square foot. The Premium Outdoor Living Package, which includes a pergola, lighting, and custom features, starts around $60 per square foot. Burns Carpentry provides a free estimate after a site visit so you get an exact number for your property.
Which lasts longer, wood or composite decking?
Composite decking lasts significantly longer, often 25 to 30 years with minimal maintenance. Wood decks, especially pressure treated pine, typically last 10 to 15 years before needing major repairs or replacement. The trade off is upfront cost. Composite costs more initially but saves money over time because you never pay for staining, sealing, or replacing rotten boards.
Can I use my deck while it is being built?
No. During construction, the work area is a jobsite with open framing, exposed fasteners, and potential trip hazards. For safety reasons, you should stay off the deck until the final inspection passes. The crew will keep the area as clean as possible, but plan on the yard being off limits for the duration of the build.
