How contractors are licensed, and how to check

It depends on the state and the trade. Some states license general contractors; others license only certain trades, such as electrical or plumbing work. Your state's licensing agency website explains which.

Look the contractor up. If a licence applies, the agency's site usually has a public lookup.

Get the quote in writing. Scope, price, timeline and who handles permits should all be on paper.

Ask about insurance. Request proof before work starts on larger jobs.
