Why Full-Frame Window Installation Is the Better Choice for Your Home
Replacing your windows is one of the best upgrades you can make to your home's comfort, efficiency, and long-term value. But there’s a major choice every homeowner needs to make: full-frame window installation vs. retrofit installation. At Great Northern Home Exteriors Inc., we install both — but full-frame provides a far superior result for most Niagara homes, especially for older properties and homeowners researching Fort Erie windows.
What Is a Full-Frame Window Installation?
A full-frame window replacement removes the entire old window system — including the frame, sash, brickmould, casing, and old insulation. This exposes the original rough opening and allows us to rebuild everything properly before installing your new KV Custom Window.
What Is a Retrofit Window Installation?
With a retrofit installation, the existing frame stays in place. We install a new window inside the old frame. Retrofit is faster and involves less carpentry — but only works when the original frames are in excellent condition with no rot or hidden structural issues.
Why Full-Frame Installation Performs Better

1. New Insulation and Proper Air Sealing
Full-frame installation lets us remove old, compacted insulation and replace it with fresh, properly sealed insulation. This drastically improves comfort and reduces drafts.
2. Hidden Rot and Water Damage Are Fixed, Not Covered
Many Niagara homes — especially in lake-effect areas like Fort Erie — have hidden moisture issues behind old frames. Full-frame installation exposes and repairs these issues instead of covering them up.
3. More Glass, Light, and Curb Appeal
Retrofit windows sit inside old frames, reducing visible glass. Full-frame restores the opening, giving you more daylight, better exterior appearance, and a larger viewing area.
4. Better Energy Performance and Home Value
KV Custom Windows can only perform to their full rating when installed into a clean, structurally sound opening. Full-frame ensures you get maximum energy savings and long-term value.
5. A True “Reset” for Older Homes
Homes 20–40+ years old often have damage behind the frame. Full-frame installation gives you a true reset, rebuilding the entire opening properly instead of installing into old, compromised material.
When Retrofit Installation Is Still a Good Choice
Retrofit can be the right solution when:
- The existing frames are 100% solid with no rot.
- You want to preserve existing interior/exterior finishes.
- You’re upgrading newer vinyl windows for efficiency.
- The home is modern with no signs of structural issues.
GNHE will always give honest recommendations — not upselling.
