How to choose a window company in Ontario
- Get two or three written quotes that list materials, labor and cleanup.
- Ask for proof of liability insurance and, for bigger jobs, workers' comp.
- Never pay the full price up front. Tie payments to finished stages of the work.
Check the license: Contractors State License Board (CSLB). In California, most home improvement work above the state's small-job limit requires a CSLB license. Look the number up before you sign, and check that it is active and bonded.
