One of the first things that comes to mind when you sign a contract to build a new deck is how long it will take. Most homeowners are excited to start using their new outdoor space, but they don’t know what to expect when the work starts.
There are a number of things that affect how long it will take to build a deck, such as how complicated the design is, what materials are used, getting the necessary permits, the weather, and the contractor’s schedule. It doesn’t take long to build a simple ground-level deck, but it does take longer to finish a bigger or more custom design.
At Decked Out Builders, the goal is not only to complete your project efficiently but also to ensure every detail meets the highest standards for quality, strength, and visual appeal.
Design and Planning Phase
Before construction starts, there’s an important planning period that includes consultation, design, and permitting.
For most homeowners, this phase lasts between two to four weeks depending on responsiveness and local permitting schedules.
In Illinois, deck construction requires permits from your local building department. Each municipality has unique requirements for drawings, engineering, and inspection stages.
Once your permit application is submitted, review times can range from a few days to several weeks depending on workload at the municipality. We manage this process entirely, handling submissions, revisions, and communication with inspectors to keep things on schedule.
Construction Timeline
Once permits are approved and materials are on-site, the actual build begins. A standard composite deck typically takes one to three weeks to complete from start to finish, depending on size and scope.
Smaller decks under 300 square feet can often be completed in about a week, while multi-level decks or those with covered roofs, lighting, or custom features require additional time.
The general order of work follows a predictable pattern.
Footings and framing: 2–5 days depending on deck size and height
Decking and fascia installation: 2–4 days
Railings, stairs, and finishing touches: 2–5 days
This schedule is also affected by the weather. Rain, freezing temperatures, or a long period of cold weather can all slow down the curing of concrete or the installation of framing. We keep a close eye on things and make changes as needed to make sure that safety and structural integrity are never at risk.
Customization and Add-Ons
Features like under-deck drainage, pergolas, lighting systems, or privacy walls extend the timeline slightly but enhance long-term enjoyment. For example, adding a screened porch or roof structure can add an additional one to two weeks depending on complexity.
Our crews specialize in full outdoor living builds, so projects that combine decks with covered porches or outdoor kitchens are managed in a way that keeps progress steady without compromising craftsmanship.
Inspection and Final Walkthrough
Most Illinois municipalities require inspections at key stages of the build, such as post-hole, framing, and final completion. These inspections guarantee that your deck complies with the code and adheres to the appropriate safety standards.
Once construction is complete, we schedule the final inspection and walk through the finished project with you. Any minor adjustments or touch-ups are promptly addressed. This process guarantees the deck is fully ready for use before you bring in furniture or decorations.
Average Total Timeline
From start to finish, a typical deck project takes six to ten weeks, including design, permitting, and construction. Smaller projects move faster, while larger or custom designs with additional features take longer.
Working with an experienced builder ensures every step moves efficiently. Clear communication, realistic scheduling, and proactive planning keep the process predictable and stress-free.
Don’t Rush
A well-built deck is worth the time it takes. Careful planning, professional craftsmanship, and quality materials deliver a finished product that enhances your home for decades.
