Windows & doors across Toronto and the GTA

A Concord team for your GTA project

GreenOn Homes manufactures and installs replacement windows and doors, with its business address at 75 Fernstaff Ct #10, Concord, ON L4K 3R3. We serve Toronto and selected communities across the Greater Toronto Area and Southern Ontario.

For homeowners in Toronto, Vaughan, Mississauga, Brampton and Markham, the first step is the same: share your address, the number of openings and what you want to change. Confirm coverage for your specific property and arrange a consultation before making travel or installation plans.

Communities we serve

What to send with your request

Tell us your city, whether you need windows, entry doors or patio doors, and the approximate number of openings. Describe access constraints, existing frame damage and any style or glass preferences. Photos can help us understand the scope before final measurements.

For condos or properties with shared exterior requirements, check with the property manager about approvals and product restrictions before ordering. Tell us about those requirements when you request a quote.
