How Much Does a Concrete Patio Cost in Illinois? (2026 Prices)

Pricing February 8, 2026

Planning a new patio and wondering what it'll actually cost? As a concrete contractor in the south suburbs of Chicago, here are the real numbers we see every day — no vague estimates or national averages.

Plain Concrete vs Stamped Concrete Pricing

Stamped concrete patio cost in Illinois — ZBL Concrete

Plain concrete patios in the Lockport, Plainfield, and Naperville area run $13 to $22 per square foot. A basic 300 square foot patio would cost roughly $3,900 to $6,600. Stamped concrete patios run $20 to $33 per square foot — so that same 300 square foot patio would be $6,000 to $9,900 with a decorative stamp pattern and color.

The biggest factor? Size. Larger patios actually cost less per square foot because setup costs (mobilization, forming, grading) get spread across more area. A 200 sqft patio might be $25/sqft while a 600 sqft patio drops to $18/sqft.

What Affects Your Total Cost

Other factors that affect price: demolition of existing concrete ($2-4/sqft extra), site access difficulty (tight side yards or hills), complex shapes with curves or multiple levels, decorative borders or two-tone color work, and built-in features like fire pit pads or seat walls.

Here's what should always be included in a legitimate quote: full excavation and grading, 4-6 inches of compacted gravel base, 4 inches of concrete minimum, rebar or wire mesh reinforcement, proper slope for drainage, and a quality sealer.

If a quote seems too low, it probably is. Common cost-cutting tricks include skipping the gravel base, pouring only 3 inches thick, not using rebar, and hiring uninsured day labor. These save the contractor money upfront but guarantee you'll be replacing that patio in 5-7 years.

Is a Concrete Patio Worth the Investment?

A well-built concrete patio is absolutely worth the investment. You'll get 25-30 years of use, it adds 5-8% to your home value, and the cost per year of enjoyment works out to pennies per day. Compare that to a wood deck that needs staining every year and replacing every 10-15 years.
