Concrete Patio Contractors Serving O'Fallon, MO & Greater St. Louis

Custom concrete patios built to last — standard, stamped, and decorative designs for homes and businesses across St. Charles County and beyond.

A concrete patio is one of the highest-return investments you can make in your home. It adds usable outdoor living space, increases property value, and — when properly installed — lasts decades with minimal maintenance. Unlike wood decks that rot and warp, or paver patios where weeds push through the joints and pieces shift over time, a properly poured concrete slab stays put. It handles Missouri’s freeze-thaw winters and brutal August heat without complaint.

And the options have never been better. Concrete isn’t the plain gray slab it used to be. Today’s patios can mimic the look of natural stone, slate, or brick through stamping and coloring — giving you a high-end aesthetic at a fraction of the cost of the real materials.

At O’Fallon Concrete Co., we’ve been installing concrete patios for homeowners and businesses throughout O’Fallon, MO and the greater St. Louis area. We’re a local company, so we understand the soil conditions in St. Charles County, the drainage challenges that come with our terrain, and the concrete mix specifications that hold up to Missouri weather long-term. That knowledge shows up in the quality of every patio we pour.

Whether you want a clean, functional slab or a stamped concrete showpiece, every project starts with a free on-site estimate and ends with your signature on an approval form — because we don’t consider a job done until you’ve walked the finished patio and told us you’re satisfied.

Concrete Patios Built to Last

Concrete Patio Services We Offer

Standard Concrete Patio Installation

A standard concrete patio is the benchmark for durability, low maintenance, and value. Our team pours and finishes every slab to precise grade and thickness specifications — typically 4 inches thick for residential patios, reinforced with rebar or wire mesh where needed to handle load and freeze-thaw cycles.

What you get with a standard concrete patio from O’Fallon Concrete Co.:

Proper site prep: We excavate and grade the area, compact the sub-base, and install forms before a single yard of concrete is poured. Shortcuts here are the #1 cause of cracking — we don’t take them.
Quality mix design: We use the right concrete mix for Missouri’s climate — air-entrained concrete that handles freeze-thaw expansion without cracking.
Clean, professional finish: Broom finish for slip resistance, smooth finish for a modern look, or exposed aggregate for texture — your choice.
Control joints: Properly placed control joints direct any potential cracking to inconspicuous locations, protecting the slab’s appearance long-term.
Curing and sealing: We apply a quality curing compound and sealer to protect the surface and extend the life of your patio.

A standard concrete patio from O’Fallon Concrete Co. is built to be the last patio you ever have to install.

Stamped & Decorative Concrete Patios

Want the look of natural stone, brick, slate, or wood — without the cost and maintenance? Stamped concrete gives you exactly that.

Decorative concrete is one of the fastest-growing segments in outdoor living, and for good reason: it’s more affordable than pavers, more durable than wood decking, and far more attractive than a plain gray slab.

Popular stamped concrete patterns we install:

Ashlar slate
Random stone / flagstone
Cobblestone and brick
Wood plank texture
European fan / herringbone
Custom geometric patterns

Color options: Stamped concrete can be integrally colored (pigment mixed throughout), surface stained, or both. We offer dozens of color options and can match your home’s exterior palette, existing hardscape, or your personal vision. Popular combinations in the O’Fallon area include warm sand tones, charcoal gray, and earthy terracotta.

How the process works:

Fresh concrete is poured and leveled to the desired grade
A release agent (color hardener or powder) is broadcast onto the surface
Rubber stamps are pressed into the concrete before it sets, creating texture and pattern
After curing, the surface is cleaned, detailed, and sealed with a high-gloss or satin sealer

The result is a patio surface that looks custom and expensive — because it is custom, just not as expensive as the materials it mimics.

Stamped concrete maintenance: Unlike wood or pavers, stamped concrete requires minimal upkeep. Resealing every 2–3 years keeps the color vibrant and the surface protected. We offer resealing services to existing customers.

Why Homeowners in O'Fallon Choose Us as Their Concrete Patio Contractor

There’s no shortage of concrete contractors in the St. Louis area. Here’s what makes O’Fallon Concrete Co. different:

We’re local — and that matters. We’re based in O’Fallon, MO. We know the soil conditions in St. Charles County, the frost depth that affects slab design, and the drainage patterns that can undermine a patio if not accounted for in the pour. You’re not getting a crew dispatched from across the metro — you’re getting your neighbors.

We don’t subcontract your job. Some concrete companies act as a middleman, selling your job and farming it out to whoever is available that week. That’s not how we operate. Our own trained crew handles your project from excavation to final seal.

Every job gets a final walkthrough. Before we consider any project complete, our installation supervisor walks the finished work with you. If anything isn’t right, we fix it. Your satisfaction sign-off is required before we leave the job site. That’s our written commitment on every project.

Licensed, insured, and accountable. We carry full liability insurance and are properly licensed in Missouri. If something goes wrong — which is rare — you’re protected.

We’ve been ranked #1 in the O’Fallon area on Google Maps by customers who reviewed our work firsthand. Our 5-star rating isn’t something we asked people to give us — it’s something we earned.

Our Concrete Patio Installation Process

We believe informed customers make the best customers. Here’s exactly what happens when you hire O’Fallon Concrete Co. to install your patio:

Step 1: Free Estimate & Design Consultation We come to your property, measure the area, discuss your design goals, and walk through material and finish options. You’ll receive a clear, written estimate — no hidden costs, no pressure.

Step 2: Site Preparation The day before or morning of the pour, our crew preps the area: excavating to the correct depth, removing debris, grading for proper drainage slope (typically 1/8″ per foot away from the house), compacting the sub-base, and setting forms.

Step 3: Reinforcement Depending on your patio’s size and use, we install rebar, wire mesh, or fiber reinforcement in the form. This is non-negotiable for any quality concrete pour.

Step 4: The Pour Concrete is delivered by a ready-mix truck and poured into the forms. Our crew works quickly and efficiently — timing is critical in concrete work. We bull-float, edge, and finish the surface to your chosen texture.

Step 5: For Stamped Patios — Stamping & Coloring For decorative concrete, the stamping happens during the pour while the concrete is still workable. Color hardener is applied, stamps are pressed, and the pattern is set before the slab cures.

Step 6: Curing & Sealing After the slab cures (typically 24–48 hours for foot traffic, 7–10 days for full strength), we apply sealer. For stamped patios, this is what brings the color to life.

Step 7: Final Walkthrough We walk the finished project with you. You approve it — or we address any concerns. Simple as that.

Frequently Asked Questions About Concrete Patios

How much does a concrete patio cost in O’Fallon, MO?

The cost of a concrete patio depends on size, thickness, finish type, and site conditions. In the O’Fallon and St. Louis area, standard concrete patios typically run $8–$15 per square foot installed, while stamped or decorative concrete patios range from $12–$25 per square foot depending on pattern complexity and color choices. The best way to get an accurate number is a free on-site estimate — measurements and site conditions matter more than any ballpark figure.

How long does a concrete patio last?

A properly installed concrete patio in Missouri should last 25–50 years or more. The keys to longevity are proper sub-base preparation, the right concrete mix for freeze-thaw climates, adequate reinforcement, control joints placed correctly, and sealing every 2–3 years. We build every patio with all of these factors in mind.

How long does it take to install a concrete patio?

Most residential patio installations take 1–2 days from start to finish — one day for prep and forms, one day for the pour and finish. Larger or more complex stamped concrete projects may take 2–3 days. You can typically walk on the patio 24–48 hours after the pour and use it fully within 7–10 days.

What’s the difference between stamped concrete and pavers?

Stamped concrete is a single poured slab with an imprinted pattern, while pavers are individual pieces of brick, stone, or concrete set in a bed of sand or mortar. Stamped concrete tends to be less expensive to install and has fewer joints where weeds can grow. Pavers are easier to repair if one section is damaged. Both look excellent — it comes down to preference and budget. We can walk you through the tradeoffs during your free estimate.

Can you pour a concrete patio in winter?

Concrete can be poured in cooler temperatures, but there are precautions required when temps drop below 40°F. We follow cold-weather concrete practices (heated water, blanket curing) when needed, but generally we schedule most pours in Missouri for the spring through fall season. Call us to discuss timing for your project.

Do I need a permit for a concrete patio in O’Fallon, MO?

In most cases, a ground-level patio slab does not require a permit in O’Fallon, MO — but requirements vary depending on size, location relative to property lines, and whether a structure will be built on it later (like a pergola or screen room). We’ll let you know during the estimate if a permit is required and can advise on the process.

How soon can you start?

We can typically schedule a free estimate within a few days and begin work within 2–4 weeks depending on the season. Spring and summer book up fast — the earlier you call, the sooner we can get you on the schedule.
