Separate product choice from installation scope
Window and door quotes can look similar while including different glass packages, frame materials, hardware, trim and installation methods. Ask for the exact product specification and which interior/exterior finishing tasks are included.
Ask how measurements and site conditions are handled
Confirm whether a site measure is required before the order is final, who checks openings, and what happens if rot, structural damage or other hidden conditions are discovered during removal. Clarify disposal and protection of the work area.
Compare warranty and schedule
Ask about manufacturer warranty, installation/workmanship coverage, service after installation and realistic product lead time. If rebates or incentive programs are mentioned, verify current program rules independently before making a purchase decision.
Check service area honestly
Some contractors serve all of Halton without a storefront in every municipality. Use the published address and service-area information separately when comparing local options.
