Get clear answers about windows, doors, installation, warranty, and financing from Ontario’s trusted local team. We’ve put together the questions GTA homeowners ask us most.
We’ve been serving Ontario homeowners since 2017, and our founder Igor Kontsevoy brings more than 15 years of hands-on window and door installation experience to every project. Over the past 8 years, our team has completed more than 10,000 window and door installations across the Greater Toronto Area and Southern Ontario and earning 300+ five-star reviews and multiple HomeStars awards along the way.
We specialize in residential window and door installation, replacement, and repair for homes of every size and style. Our window lineup includes casement, awning, double hung, single hung, double slider, single slider, end vent slider, fixed casement, picture, and energy-efficient vinyl windows. For doors, we install entry doors, patio doors, fiberglass doors, steel doors, and vinyl doors. Whether you’re replacing a single failed window, upgrading every opening in your home, or outfitting a new build, we offer fully custom-fit, Ontario-made products tailored to your home.
Our team installs windows and doors in more than 19 cities across Southern Ontario, including Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Hamilton, Oshawa, Barrie, Newmarket, Aurora, Stouffville, Keswick, East Gwillimbury, Kitchener, Waterloo, Cambridge, St. Catharines, and Niagara Falls – plus the surrounding communities in between.

Yes! We know replacing windows and doors is a significant investment, so we offer 0% interest financing through our partner FinanceIt, with funding available up to $100,000 per project. You can defer payments for up to 12 months or spread them over as many as 60 equal installments.
We also help homeowners take advantage of Ontario’s Home Renovation Savings Program, which can rebate up to 30% of the cost of qualifying energy-efficiency upgrades like new windows and doors.
Three things set us apart. First, we don’t subcontract. Every installation is handled by our own certified, in-house crew, which is why our reviews consistently mention clean job sites and precise workmanship.
Second, our warranty is one of the strongest in Ontario: a comprehensive lifetime warranty covering product, installation, and service for 25 years with no fine print.
Third, we’re a local Ontario business that has grown through word of mouth, not high-pressure sales so our quotes are transparent, written, and price-matched against any equivalent estimate.
Combine that with ENERGY STAR® certified, Canadian-made products built for Canadian weather, and you get a company homeowners actually recommend to their neighbours.
Absolutely. Window Experts was founded in Newmarket in 2017 and is still proudly headquartered there at 110 Pony Dr., Unit 17.
We’re a local, independently owned business ie not a franchise and our entire team lives and works in the same communities we serve. All of our windows are manufactured right here in Ontario, our installers are based across the GTA, and we take real pride in being the company your neighbours trust to get the job done right.
