Residential contractor comparison guideHow to Choose a Glass or Window Contractor in Toronto
Use the same scope and questions for every company so you can compare residential glass and window quotes more meaningfully.
First question
Does the company regularly do your type of project?
A company focused on complete residential window replacement may approach a failed insulated glass unit differently from a glass service company. Shower specialists, railing companies and emergency glass companies also have different normal scopes.
Glass-only replacementAsk whether the existing sash or frame is intended to remain.
Complete windowsConfirm whether the quote is insert-style, full-frame or another installation method.
Custom glassConfirm thickness, tempering, polishing, hardware and fabrication.
Emergency workSeparate temporary securing from permanent replacement when both are required.
Quote checklist
Ask every company the same core questions
Price & responsibility
- Is HST included or additional?
- What can change the quoted amount?
- Who performs the installation?
- What warranty applies?
- What happens if hidden frame damage is found?
Before requesting quotes
Give every contractor the same information
Take a full-opening photo, a close photo of the problem, interior and exterior views where practical, approximate width and height, quantity, property type and access information. Better initial information makes comparisons more useful.
