Most contractor problems are preventable. These checks take under an hour and catch the most common hiring mistakes.
Ask for their MO contractor license number, then verify it yourself at the state licensing website before signing anything.
Request a certificate of insurance. Call the carrier directly to confirm general liability and workers' comp are active.
Get at least three written bids. Any quote more than 30% below average is a red flag, not a deal.
Ask specifically about permit requirements for window replacement. A contractor who says "no permit needed" for structural work is a liability.
Read recent Google and BBB reviews for complaint patterns, not just star averages. One-star reviews reveal how disputes get resolved.
AboveBoardPros gives you a head start on checks 1 and 2.
In the states our automated check reaches, we cross-check the business against the state registry, and we read the certificate of insurance where a contractor provides one. You still confirm the trade license with your state and ask for a current certificate before you sign.

Timeline depends on project scope. Ask for a written schedule before work begins, and specifically ask about material lead times and permit inspection windows: these cause most delays.
