Free5 Things Every Fort Thomas Homeowner Should Verify
Most contractor problems are preventable. These checks take under an hour and catch the most common hiring mistakes.
Ask for their KY 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 home addition. 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.

Yes. Fort Thomas enforces active licensure and insurance. Ask any contractor for their license number and verify it at the KY state licensing website before signing a contract.
How does AboveBoardPros select home addition contractors?
For the pros we list, we cross-check the official state business registry where our automated check reaches, scan the contractor's own website for credential claims, and pull public business signals.
