Hiring in Connecticut
Ask for the license or registration number and proof of insurance, get two or three written bids, keep payments behind the work, and confirm who pulls permits. The hiring checklist and the payment schedule calculator walk you through it. Trades such as electrical and plumbing are often licensed separately from general contracting, so ask about each one.
