What questions should I ask before signing with a window company?

Before signing with any window company, ask about their licensing, insurance, warranty coverage, and get detailed written estimates. The right questions upfront can save you thousands and prevent major headaches down the road.

Licensing and Insurance Verification is your first priority. Ask to see their WSIB coverage and general liability insurance certificates - legitimate contractors carry both and will readily provide proof. Verify they're licensed for window installation in Ontario, as this ensures they understand building code requirements and proper installation techniques. Don't just take their word for it; ask for documentation you can verify independently.

Product and Installation Details require specific questions about materials and methods. Ask what brand of windows they install, the glass specifications (double vs triple-pane, Low-E coatings, gas fills), and frame materials. Get details about their installation process - do they remove old trim carefully for reuse, how do they handle insulation and air sealing, and what's included in cleanup? Quality installers will explain their process thoroughly and highlight energy efficiency features relevant to Ottawa's climate.

Warranty and Service Coverage varies dramatically between companies. Ask about manufacturer warranties on the windows themselves versus installation warranties from the contractor. Find out who handles warranty service calls - some companies disappear after installation, leaving you to deal with manufacturers directly. Get specific timeframes: how long do they warranty their installation work, and what exactly does it cover? Quality window companies in Ottawa typically offer 2-10 years on installation workmanship.

Financial and Timeline Questions protect your investment. Never pay large amounts upfront - reputable contractors typically ask for minimal deposits. Get a detailed written estimate breaking down materials, labor, permits (if needed), and cleanup. Ask about their timeline, how weather delays are handled, and their policy on change orders. For Ottawa installations, understand their winter work limitations and seasonal scheduling.

References and Local Reputation matter significantly for major home improvements. Ask for recent local references you can contact, and check online reviews on multiple platforms. Find out how long they've been serving the Ottawa area and whether they're part of local trade associations. A company with deep Ottawa roots is more likely to stand behind their work long-term.
