The home improvement experts at Brookstone Windows & Doors offer a wide range of high-performing replacement windows and exterior doors that can fortify your Kitchener-area home against the Ontario climate. Family-owned and -operated, Brookstone has cemented its reputation as the premier window and door installation company in the area, and has garnered significant industry praise for the unparalleled quality of their products and services. Furthermore, they offer one of the best warranties out there – a no-nonsense, no-small-print, lifetime warranty that covers all products and labour – so you can rest easy knowing that the investment you’ve made in your home is protected.

Durable, Canadian-Made Replacement Windows

We manufacture our own vinyl replacement windows right here in Canada. With frames crafted from 100-percent virgin PVC, these windows will never crack, fade, warp, or chalk, meaning they’ll retain their like-new appearance for years to come. What’s more, with insulated frames and energy-efficient low-e glass, our windows will help your home maintain a more comfortable and consistent indoor temperature which will lessen your HVAC system’s workload and potentially reduce your monthly heating and cooling costs.

Exterior Doors Built for the Ontario Climate

Our exterior doors are also made with the Ontario climate in mind and can give your home the boost in curb appeal that it needs. We offer heavy-duty steel doors, available with a smooth or embossed finish, and a variety of fiberglass doors that feature beautiful authentic-looking woodgrain finishes. Pair your new front entry door with matching sidelights to make a grand entryway, and finish it off with a storm door to add an extra layer of protection against the elements. Additionally, we can install vinyl patio doors in single, double, triple, or quadruple configurations so you can design a rear or side entryway for your home that is as large or small as you desire.

Our Commitment to Customer Satisfaction

We only trust installation to our certified, highly trained technicians, so you can rest assured that your replacement windows and exterior doors will be installed promptly and properly the very first time. We stand behind our work with a no-nonsense lifetime warranty that covers products and labour, so, when you partner with Brookstone Windows & Doors, you can enjoy the added peace of mind that comes from working with a company that truly cares.
