Concrete Patio Installation Des Moines - New Patios & Patio Extensions

Concrete patio installation in Des Moines starts with how you actually use the backyard: the grill, the table, the fire pit, the path to the gate.

We pour broom-finish and smooth-trowel patios, and we extend patios that turned out too small.

Sizing It Right

A patio that's a few feet too small is a common complaint. A dining table for six with chairs pulled out takes more room than most people guess, and a grill needs clearance from the house siding and from the table. We'll mark the outline with paint or stakes on the site visit so you can stand on it before anything is dug. For reference, HomeGuide prices a plain 10' x 20' concrete patio at $800 to $2,400 nationally.

What a Patio Costs Nationally

Angi's 2026 national average for a concrete patio is $3,557, and most homeowners spend between $1,919 and $5,393. Angi also notes that the average deck costs roughly twice as much as the average concrete patio. Your price depends on size, how much digging and base the yard needs, how far the truck has to reach, and the finish.

Drainage Comes First

Every patio we pour slopes away from the house. On a lot of Des Moines lots the back of the house sits a little low, and a patio that tips toward the foundation sends every storm toward the basement wall. If the grade doesn't allow a good slope, we'll talk about a step down, a drain, or reshaping the yard before we form.

Planning for Heavy Things

A hot tub, an outdoor kitchen, a stone fireplace or pergola posts all add point loads. Angi's guidance for that kind of load is 6 to 8 inches of concrete with reinforcement, compared with the thinner slab a table and chairs need. Tell us up front, because thickening one area costs much less on pour day than adding a pad later. Small stand-alone pads are covered on our concrete pads page.

Finishes

  1. Broom finish. Grippy and inexpensive. The most practical choice for a patio that sees snow.
  2. Smooth trowel with a broom border. Cleaner look, with a framed edge.
  3. Saw-cut patterns. Decorative joints cut in a grid or diamond layout, which also control cracking.
  4. Stamped, colored or exposed aggregate. See stamped concrete and exposed aggregate and colored concrete.

Patio Extensions

Adding onto an existing patio works if the old slab is sound and level. We tie the new section in at the same height, keep the joint lines continuous, and use the same finish. Matching the color of a weathered slab exactly isn't always possible, so a saw-cut border or a contrasting band at the seam often looks more deliberate.
