Vinyl windows run $600–$1,200 installed per window, with triple-pane upgrades adding roughly $900–$1,800. A full-home replacement typically ranges $8,000–$18,000 depending on window count, size and frame type. ### Do your windows qualify for the Canada Greener Homes Grant? Yes. Our Energy Star Zone C certified installations are eligible for the Canada Greener Homes Grant and Enbridge HER+ rebates, subject to a registered energy assessment. We help you understand eligibility during your quote. ### Do you use subcontractors for installation? No. Every window and door is installed by our own in-house crews, which is how we keep quality consistent and stand behind our 10-year labour warranty. ### What U-factor do windows need in Toronto? Toronto sits in Climate Zone 6, so Energy Star Zone C products are the target. Our triple-pane systems reach U-factors as low as 0.14 for the best comfort and efficiency in GTA winters. ### Can you fix foggy windows without replacing the whole window? Often, yes. If the frame and hardware are sound, we replace just the failed insulated glass unit (IGU), a lower-cost fix that restores clarity and insulation. If the frame is also failing, we'll explain the repair-or-replace trade-off honestly. ### What makes European tilt-and-turn windows different? As authorized Schuco, Reynaers and Cortizo dealers, we install tilt-and-turn systems with dual-action operation, multi-point RC1–RC4 security hardware and slimline thermally broken aluminum frames, delivering performance beyond typical vinyl-only options. ### What warranty do you offer? We back our installations with a 10-year labour warranty, in addition to manufacturer product warranties. We're also Energy Star Canada certified, CSA A440 compliant and WSIB insured. ### Which areas do you serve? We serve the entire Greater Toronto Area, including Toronto, Etobicoke, North York, Scarborough, Mississauga, Brampton, Vaughan, Markham, Richmond Hill and Oakville. In Oakville and Vaughan we handle a high share of premium European system installs. ### How much does a new entry door cost? Entry doors run $1,500–$4,500 installed, depending on material (steel or fiberglass), glass options like sidelites and transoms, and multi-point security hardware. ### How long does installation take? A standard entry door is typically installed in a single day. Whole-home window projects usually take one to a few days depending on the number of windows and whether it's retrofit or full-frame work. ### Still have a question?
