• Are you licensed, bonded, and insured?

• Do you have worker’s compensation?

• How long have you worked with your subcontractors?

• How do you handle garbage and waste disposal?

• Do you provide a guarantee or warranty on your work?

• Do you give free estimates?

• How do you handle change orders?

• Can you provide at least three references?

• Can I see some of the work you’ve done in photos and the actual project?

Concrete repair costs range anywhere from about $0.10 to $0.15 per linear foot to fill minor cracks, to about $6 to $14 per square foot to replace damaged concrete slabs.

Yes, concrete contractors should be licensed, and for good reason. Hiring an unlicensed concrete contractor could lead to poor quality work, costly future expenses, and potential code violations. States have different requirements for concrete contractor licensing, so be sure to check our state licensing tool to review the local guidelines.

Depending on the cost to repair your driveway, it may be more cost effective to tear out and replace it with a new concrete driveway. The cost to repave a driveway ranges between $1,400 and $12,100, including removal of the old concrete. Contact a reputable concrete contractor for advice and an estimate. They may have a good reason for going with repairs or replacement after assessing your driveway. You may also have the option to resurface your driveway or pave over it without taking out the existing one.

Concrete contractors typically charge anywhere from $6 to $14 per square foot. Cost factors include job size, site prep, base material, accessibility, your location, concrete finish, and concrete thickness. Removal of existing concrete, asphalt, deck, pavers, and grass will cost anywhere from $1 to $6 per square foot. Homeowners can often save money by removing and disposing of existing pavers, decks, and grass. Breaking up and hauling away concrete and asphalt is difficult and time-consuming without the proper equipment and may be worth having the pros do that work.
