Decks & Patios Builder in Central Illinois
Most backyards across Tremont, Pekin, Morton, Washington, and the greater Peoria area go completely unused from May through October and not because people don't want to be outside, but because there's nowhere comfortable to actually sit. A well-built deck or patio changes that completely. At Mathes Construction, we've been building outdoor living spaces for Central Illinois homeowners since 1977. We build wood decks, composite decks, concrete patios, and multi-level outdoor spaces that are designed around how you actually use your yard and built to hold up through the kind of weather Illinois throws at them year after year. Our own crew does the work, no subcontractors, and every project starts with a written estimate you can count on.
WHY CHOOSE MATHES CONSTRUCTION FOR YOUR DECK OR PATIO
Deck or Patio Built to Last Through Illinois Seasons
A lot of homeowners in Tremont, Pekin, Morton, and across Tazewell County have had a deck built that looked great the first summer and started showing problems by year three. Boards warping, posts rotting at the base, railings that wiggle, fasteners that rust through and stain the wood. That's what happens when someone builds a deck fast and cheap without thinking about what Central Illinois weather does to outdoor structures over time. We've been building decks and patios across the greater Peoria area since 1977 and we build them to hold up like not just look good on the day we finish. We use the right materials for the application, set posts properly below the frost line so they don't heave in winter, and pay attention to drainage so water moves away from your home instead of sitting against it. Whether you want a simple ground-level deck off your back door, a multi-level deck with built-in stairs and railings, or a concrete patio that connects to your existing landscaping. Chuck Mathes will look at your yard, talk through your options honestly, and give you a written estimate before any work starts.

Deck and Patio Projects We've Built Across Central Illinois
Over nearly 50 years, we've built decks and patios for homeowners across Tremont, Pekin, Morton, Washington, Bartonville, East Peoria, Peoria, and Mapleton and no two projects looked the same. Some homeowners wanted a simple pressure-treated wood deck off the back door where they could grill and have a few chairs. Others wanted a multi-level composite deck with built-in seating, stairs down to the yard, and lighting along the railings. We've built concrete patios that connect to existing landscaping, stamped concrete patios for homeowners who wanted something that looked more finished, and combinations of both where a patio transitions into a deck. Every single one of those projects was built by our own crew, and every homeowner got a finished product that was properly set, properly drained, and built to handle what Central Illinois winters and summers actually throw at outdoor structures year after year.
What Makes a Deck or Patio Actually Worth Building
The difference between a deck that lasts 20 years and one that starts falling apart in five usually comes down to a few things most homeowners don't think about until it's too late. How deep the posts are set and if they're not below the frost line for Tazewell County, they'll heave and shift every spring. How the ledger board is attached to your house done wrong, it's the number one cause of deck failures and water damage to the home behind it. How drainage is handled on a patio concrete that sits flat and holds water will crack faster and can direct moisture toward your foundation. These aren't dramatic problems. They're just details that a contractor who does this right handles automatically, and one who doesn't will skip because they slow things down. We've been building outdoor spaces across the Peoria area since 1977. The details are part of the job.
Built for Illinois Weather
Central Illinois gets hard winters, wet springs, and hot summers. Every deck and patio we build is constructed with that in mind — from post depth to material choice to how water drains off the surface and away from your home.

ABOUT OUR DECK AND PATIO WORK
Decks and Patios That Still Look Good Ten Years Later
The Peoria area has no shortage of guys who will build you a deck over a weekend for a low price. Some of them do decent work. A lot of them don't and you won't know which one you hired until a few years pass and the problems start showing up. Posts that weren't set deep enough start leaning after a couple of freeze-thaw cycles. A ledger board that wasn't properly flashed starts letting water into your rim joist. Composite decking that was installed without proper gap spacing starts buckling in the summer heat. These aren't things most homeowners know to ask about upfront, and a contractor who cuts corners knows that. At Mathes Construction, we've been building decks and patios across Tremont, Pekin, Morton, Washington, Bartonville, East Peoria, and the greater Peoria area since 1977. We do this work the right way because we've seen what happens when it's done wrong, and we're not interested in getting a call two years from now about a deck we built that's already falling apart.

Frequently Asked Questions
Questions About Decks and Patios in Central Illinois
Before starting a deck or patio project, most homeowners across Tremont, Pekin, and Tazewell County have the same questions. Here are straight answers to what we hear most.
Still Have Questions?
We’re here to help you!
How much does a deck or patio cost in Central Illinois?
A basic pressure-treated wood deck typically starts around $8,000–$15,000 depending on size. A composite deck with stairs, railings, and built-in features runs $18,000–$35,000 or more. A concrete patio can range from $6,000 for a simple pour to $20,000+ for a larger stamped concrete project with borders and a finish. We don’t quote numbers without seeing your yard first like lot slope, access, existing landscaping, and what you want the space to do all affect the price. We come out, take a look, and give you a written estimate that’s accurate.
Do I need a permit to build a deck in Tazewell or Peoria County?
Most decks over 30 inches off the ground require a building permit in Tazewell and Peoria counties, and all decks attached to the house need one regardless of height. We handle the permit process for every deck we build. Skipping permits on a deck is one of the most common mistakes homeowners make and it causes real problems when you go to sell the house or file an insurance claim after storm damage.
How long does it take to build a deck or patio?
A straightforward deck build typically takes 1–2 weeks once materials are on site. A larger multi-level deck with custom features can run 2–4 weeks. A concrete patio is usually 3–5 days for the pour and finishing, plus curing time before you can use the space. We give you a timeline upfront and we stick to it and we don’t start a project and then disappear for days while your backyard sits torn up.
What deck and patio services do you offer across Central Illinois?
We build pressure-treated wood decks, composite decks, ground-level decks, multi-level decks, attached and freestanding patios, poured concrete patios, and stamped concrete patios. We serve Tremont, Pekin, Morton, Washington, Bartonville, East Peoria, Peoria, and Mapleton. If you’re in Tazewell or Peoria County and want an outdoor space built by people who actually know what they’re doing, give us a call.
