Most contractor problems are preventable. These checks take under an hour and catch the most common hiring mistakes.
Ask for their IL 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 sun room. 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.

Sunroom additions require a full building permit and are treated as room additions by building departments. They must meet all applicable codes including energy efficiency, structural loads, egress, and electrical. A four-season sunroom is held to the same standards as any other heated living space.
