New Deck Construction in Peoria, IL

What Goes Into Building a Deck in Peoria, IL

A deck in Central Illinois needs to be built differently than one in Arizona or the Southeast. Peoria winters bring repeated freeze-thaw cycles — temperatures crossing 32°F dozens of times between November and March — and that cycling puts stress on footings, framing, fasteners, and decking material. Get the structure wrong and a deck looks good for a year or two and then begins to move, squeak, and degrade.

We dig footings to the proper depth for Tazewell and Peoria County frost lines — typically 42 to 48 inches — set posts correctly, use appropriately rated pressure-treated lumber throughout the framing, and select fasteners and hardware rated for the exposure level of the project. It’s not glamorous, but it’s why our decks look the same in year eight as they did in year one.

Deck Types We Build

Every backyard is different. We build across the full range of residential deck types:

• Ground-level platform decks — simple, cost-effective, and no railing required in most jurisdictions when under 30 inches off grade. Popular in older Peoria neighborhoods with flat backyards.
• Raised and elevated decks — for homes on slopes or with walkout basements. Requires proper post sizing, ledger attachment, and stair systems.
• Multi-level decks — connecting different elevations of your yard or home. More complex to frame but dramatically increases usable outdoor space.
• Wraparound decks — extending along two or more sides of the home. Excellent for corner lots or homes where the best views are on a different side than the back door.
• Pool decks and detached platforms — freestanding decks not attached to the home, or deck surfaces surrounding above-ground pools.

The Build Process

We keep it transparent from the first conversation to the final walkthrough. Here’s what to expect:

1. Free on-site estimate — we come to your property, measure the space, discuss your goals, and leave you with a written quote with a specific price. No vague ranges.
2. Permit pull — most new deck projects in Peoria and surrounding municipalities require a permit. We handle the application and schedule the inspection.
3. Footing installation — concrete footings dug to frost-line depth. This is the most critical part of the build. We don’t cut corners here.
4. Framing — posts, beams, joists, and ledger attachment to the home (if applicable). Inspected before decking goes down on permitted projects.
5. Decking installation — boards run, fastened, and cut to the final profile. This is the part that’s visible when it’s done.
6. Railing and stairs — code-compliant railing systems and stair construction where required or requested.
7. Final cleanup and walkthrough — site cleaned, job reviewed with you in person.
