Custom Deck Building in Belleville, IL

Your backyard is some of the most underused square footage on your property. A professionally built deck changes that — giving you a dedicated space for entertaining, relaxing, grilling, and simply enjoying the outdoors. Frame to Finish Construction LLC has been building custom decks throughout Belleville, Swansea, O'Fallon, and the rest of St. Clair County, and we know what holds up in the Metro East Illinois climate and what doesn't.

From a clean 12x16 pressure-treated platform to a sprawling multi-level composite deck with a pergola, cable railings, and built-in bench seating, we handle the full job — design, permits, construction, and cleanup. No subcontracting the framing to one crew and the finish to another. One team, one point of contact, one finished product.

Wood Decks: Affordable and Classic

Pressure-treated lumber remains the most popular deck material in Belleville for one simple reason: it costs less upfront. A well-built PT wood deck in the $10,000–$18,000 range gives you a solid, structurally sound outdoor platform that will last 15–20 years with proper maintenance. Cedar and redwood are also options for homeowners who want a more natural, premium look without going full composite.

The trade-off with wood is maintenance. Belleville summers are hot and humid, and winters bring freeze-thaw cycles that are hard on untreated lumber. You'll need to seal or stain a wood deck every 2–3 years to prevent cracking, warping, and rot. We build wood decks right — proper spacing, stainless fasteners where it counts, and flashing at the ledger board — so the maintenance you do actually works.

Composite Decking: Low Maintenance, Long Life

Composite decking has come a long way. Modern boards from brands like Trex, TimberTech, and Fiberon look convincingly like wood grain, resist fading, and require almost zero upkeep beyond an occasional rinse. In the Metro East climate, composite is frequently the smarter long-term investment despite the higher upfront cost — typically $22,000–$40,000 for a mid-to-large deck with full features.

Composite decks also tend to hold their value better. When buyers compare similar homes in Belleville and O'Fallon, a low-maintenance composite deck is a selling point. Real estate data consistently shows decks returning 60–70% of their cost at resale — and composite returns tend to run higher because buyers aren't pricing in a future maintenance bill.

Pergolas, Railings, and Built-In Features

A deck is more than the platform. Frame to Finish also builds pergolas and shade structures that extend the usability of your space deep into summer. We install cable railings, aluminum balusters, and traditional wood or composite railing systems — whatever fits your budget and aesthetic. Built-in bench seating, planter boxes, and integrated lighting are all available as part of a full deck build or as add-ons to an existing structure.

If you're thinking long-term, we can also rough in electrical conduit during construction so adding lighting or an outdoor outlet later doesn't require ripping up your deck boards. These small decisions during the build save real money down the road.

Permits and St. Clair County Building Codes

Deck permits are required in Belleville and most other St. Clair County municipalities for attached decks and any deck elevated more than 30 inches from grade. Frame to Finish handles all permit applications, plan submissions, and inspections. We know the local codes — setback requirements, ledger attachment standards, footing depth for Illinois frost lines — and we build to them from day one so inspections don't hold up your project.

Skipping permits to save a few hundred dollars is a common mistake that creates big headaches at resale. Unpermitted structures have to be disclosed to buyers and can complicate title insurance. Don't cut that corner. We make the permit process painless.
