Trusted Installers. Proven Results. Real Accountability.
Since 2009, Great Northern Home Exteriors Inc. has been the trusted choice for local homeowners upgrading their homes with quality, Canadian-made windows. From established neighbourhoods like Dain City and Cooks Mills to properties near the Welland Canal, our in-house installation team delivers professional workmanship that improves comfort, curb appeal, and energy efficiency — all supported by warranties that truly matter.
Comfort Built for Every Season
In Niagara, the real “test” for windows is the swing between cold, windy winters and warm, humid summers. That’s why the right upgrade isn’t only the frame — it’s the glass package you choose for your rooms, exposures, and how you use the space.
We help you pick a setup that reduces drafts, improves temperature stability, and keeps sunlight comfortable — without turning your living room into a greenhouse in July or an icebox in February.
Here’s what we look at when recommending the best glass package for your home:
Low-E + Argon Fill
A strong baseline for efficiency — helps reflect indoor heat back in winter and reduces energy loss through the glass.
Double vs Triple Pane
We match pane count to the room and exposure — triple can boost comfort and quiet in the spots that need it most.
Solar & UV Control
Helps manage glare and overheating while protecting floors and furniture from UV.
Professional Window Installation in Welland
At Great Northern Home Exteriors, our knowledgeable team provides professional window installation in Welland, supporting both retrofit and full-frame window replacements. Every project is completed with precision, care, and attention to detail — helping your home stay comfortable, energy efficient, and beautiful for years to come.
Retrofit (Insert) Installation
Your new windows are fitted into the existing frames. This option is cost-effective and less invasive, finished with Cove trim on the inside and durable aluminum capping on the outside.
Full-Frame (Brick-to-Brick) Installation
The entire window — including casings and jamb extensions — is removed and replaced. This method delivers the highest energy efficiency and can include new vinyl brickmould on the exterior for a clean, modern finish.
Whichever installation method you choose, our team guarantees precision, attention to detail, and results that last — enhancing both the comfort and appearance of your home for years to come.

- Transparent pricing with no surprises
“Bought a home in Welland in 2020 (yep, the year common sense went ‘out the window’) and decided to replace the original contractor-grade windows and doors. GNHE helped us navigate supply-line and pricing issues with confidence, matched exposures for UV control, upgraded our patio door to a larger size, and even offered a pet-proof screen option. The measurer was also the skilled installer — so everything stayed on time, on budget, with no follow-up issues. When it was time to replace the remaining windows, we didn’t even look elsewhere. Quality and integrity still exist — we confidently recommend them.”
