Installation options: full-frame vs. retrofit
trained professionals who specialize in both retrofit and full-frame window replacements. Our process ensures your home gets the right solution for comfort, efficiency, and long-term durability.
Retrofit (Insert) Installation

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, are removed and replaced. This method delivers the highest energy efficiency and can include new vinyl brickmould on the exterior for a clean, modern finish.

Niagara Falls Window Replacement FAQ
How much does it cost to replace windows in Niagara Falls?
Costs depend on window size and style, glass options, and whether you choose retrofit or full-frame installation. We provide a clear, written estimate so you know your total investment before any work begins.
Do I need a building permit to replace my windows?
Most standard replacements do not require a permit unless you enlarge an opening or make structural changes.
You can confirm by visiting the Niagara Falls Building Services Portal
or check the City Hall Departments page.
What’s the difference between retrofit and full-frame installation?
Retrofit installation fits new windows into your existing frame — faster and typically more cost-effective.
Full-frame (brick-to-brick) replacement removes the entire old unit and rebuilds the opening for maximum energy efficiency and a full refresh.
How long does a window installation take?
Many projects are completed in one day, depending on the number of windows and layout.
Our in-house installation crews work efficiently, protect your space, and clean up before leaving.
Are you a local window company or just a sales office?
Great Northern Home Exteriors is a locally owned and operated company serving Niagara homeowners since 2009. We’re not a franchise or temporary sales outlet — our full-time, WSIB-insured installation crews live and work right here in the Niagara Region. Every project is backed by a 5-year workmanship warranty and lifetime product warranties from KV Custom Windows, so you can count on professional results and long-term peace of mind.
