Get matched with top concrete patios, walks & steps installers in your area

In most cities, you’re on the hook for the stretch of sidewalk that borders your property, but rules vary by municipality. Some towns split the bill—or pay it all—if the damage comes from city tree roots or utility work. Before you start repairs, call your local public works department to confirm who pays what and ask whether any cost-sharing or reimbursement programs exist.

Start with the basics: Are you licensed and insured, and how long have you been pouring sidewalks? Next, pin down the details—ask how long the work is guaranteed, whether the crew handles permits, and if they’ll provide references from recent jobs. A reputable pro should answer confidently, put warranty terms in writing, and welcome follow-up questions.

Most repairs wrap up in one to three days. A simple crack seal can be finished in a single afternoon, while lifting or replacing slabs can stretch to a couple of days plus curing time. You should factor in extra time if permits or inspections are needed for your repair service.

Measure the damaged area, snap a few photos, and have at least three concrete pros quote the job. Most repairs fall between $726 and $2,485, or $5 to $15 per square foot, so multiple bids help you spot outliers and lock in a fair price.

Patch a hairline crack yourself if you’re handy and have the right materials, but call a pro for anything that involves leveling, new concrete, or stamped designs. Contractors arrive with specialized gear, plenty of experience, and the permits already sorted—saving you time and ensuring the repair meets code and lasts.
