How Can I Verify My Window and Door Installer Is Licensed and Insured?
Ask any installer for a license number and proof of current insurance before signing a contract, and confirm both with the state or local licensing office if you want extra certainty. Ask what the license covers and what the insurance protects against, so you know whether you're working with licensed and insured installers or someone subcontracting the job out. Get the license number, insurance carrier, and policy details in writing as part of your estimate, not just a verbal assurance, and ask whether the work includes a written warranty on installation and what it covers.
