How We Work, Start to Finish
Knowing what comes next takes the stress out of home improvements. Here is our step-by-step approach to every build.
First Conversation and Yard Walk
We meet at your home to look at the site, measure the layout, and check ground slope near the foundation. We discuss how you want to use the deck, review material preferences, and look closely at existing home attachment points.
Blueprints and Material Choices
Our team puts together detailed structural plans based on your yard's footprint. We firm up material choices—comparing composite lines against natural woods—and handle all paperwork required for local St. Charles County building permits.
Framing and Construction
Footings are dug and concrete poured past the regional frost depth. We set support posts, square up the heavy joist framing, and lay decking boards with clean lines and hidden fasteners where requested. We keep job sites picked up at the end of every work day.
Final Inspection with You
Once the last board is fastened and railings are secure, we walk the entire build with you. We check hardware connections, review cleaning tips for your specific decking material, and make sure every detail meets our standards.
What Your Neighbors Say
Read through reviews from homeowners across the county. We focus on clean framing, direct communication, and building structures that stay solid year after year.

Common Questions
A standard single-level build takes about three to five working days once footings are set and concrete cures. Larger projects—like multi-tiered platforms, wrap-around steps, or builds featuring integrated pergolas—often take two to three weeks. Heavy rains can pause digging and concrete work, but we keep you updated daily on schedule shifts.
We calculate pricing using total square footage, height off the ground, access to the workspace, footing needs, and material selection. Standard treated pine carries lower initial material costs than cap-stock composite decking, though composite cuts out annual stain and seal expenses. Features like post lighting, metal balusters, and picture-frame borders will also factor into the material total.
Cap-stock composite decking holds up exceptionally well against regional humidity, intense summer sun, and winter frost cycles. It doesn’t absorb water, splinter, or warp. Pressure-treated pine and cedar remain solid traditional choices, provided you stay on top of washing and sealing every few seasons to block ground moisture.
Yes. If your underlying support frame is structurally sound, we can remove rotted or warped deck boards, rebuild unsafe stairs, and install modern railing systems. If inspection shows deteriorating support posts or missing ledger flashing, we’ll give you an honest opinion on whether structural repairs make sense or if full rebuild is safer long-term.
We do this regularly. Combining an elevated composite or wood deck with a lower paver patio creates logical zones for cooking, dining, and fire pit seating. We design transition steps and walking paths so movement between your indoor spaces, deck level, and yard feels natural and easy.
Check for verified liability insurance, active state licensing, and local project references in St. Charles County. Look for clear written estimates that detail framing specs and hardware types—not just board counts. A dependable contractor handles the permit process directly and explains how they build to local structural codes.
Building codes in West Alton require permits for structural deck additions to verify footing depth, ledger attachment safety, and handrail heights. Supreme Decks drafts necessary framing diagrams, submits permit applications, and schedules all required county inspections as work progresses.
We hand over practical care guidelines specific to your material choice—whether that is simple soap-and-water washing routines for synthetic boards or timing advice for initial wood sealing. If you ever have structural questions down the road, you can call us directly.
