Expert Window Installation You Can Trust
At Great Northern Home Exteriors, every project is completed by trained professionals who focus on accuracy, cleanliness, and long term performance. Whether you choose full-frame installation or a clean, efficient retrofit upgrade, we ensure a proper fit that improves energy savings, comfort, and durability for years to come.
Retrofit (Insert) Installation
New units are custom-fitted into your existing frames, providing an efficient and budget-friendly upgrade without disturbing interior finishes. Every retrofit is completed with clean Cove trim inside and durable aluminum capping outside for a neat, weather-resistant finish that holds up year after year.
Full-Frame (Brick-to-Brick) Installation

Whichever installation method you choose, our team delivers precise workmanship, clean finishing, and long-term performance — giving your home improved comfort, efficiency, and a polished look that lasts for years.

Port Colborne Window Replacement FAQ
How much does it cost to replace windows in Port Colborne?
The cost depends on factors such as window size, glass options, and the type of installation. Retrofit installations are generally more budget-friendly, while full-frame replacements offer maximum efficiency and long-term value. Our team provides clear, on-site quotes so you always know what to expect.
Do I need a building permit to replace my windows?
Most standard window replacements do not require a building permit. However, structural changes — such as enlarging an opening — may need approval. For up-to-date information, visit the City of Port Colborne Building and Renovating page , or ask our team during your consultation.
What’s the difference between retrofit and full-frame installation?
Retrofit installation places new windows inside your existing frames, making it ideal when the original frames are still solid. Full-frame installation removes everything down to the studs and provides the best upgrade for insulation, structure, and appearance. We’ll help you determine which approach is best for your home.
How long does a window installation take?
Most installations can be completed in a single day, depending on the number of windows and weather conditions. Our installers work efficiently to deliver a clean, professional finish with minimal disruption to your home.
