Ask for current insurance and applicable WSIB documentation, along with the installation arrangements for your project, before work begins.

It depends on the condition of your existing frame and trim. A full replacement removes the entire frame and sash and makes sense if there's frame damage or you want a bigger efficiency upgrade. A retrofit reuses your existing frame and trim and is a more economical option when they're still in good shape. A GreenOn Homes advisor can walk you through which one fits your home.
Ask about the payment options currently available for your project. Confirm the provider, eligibility, interest and full terms before making a decision.
