Full-Frame vs. Insert Window Replacement: What’s the Difference?

The two main approaches are full-frame replacement and insert replacement, which is also known as pocket replacement.

How full-frame replacement works

A full-frame job takes out the entire existing window assembly, including the frame, sash, and in many cases the interior trim and exterior stops around the opening.

That approach gives the crew a clean view of the rough opening, which makes it easier to spot rot, water intrusion, or structural issues hiding behind the old window.

How insert replacement differs

Insert replacement leaves the original frame in place and installs a new window unit inside it.

Homeowners sometimes choose insert replacement when the frame is still solid, square, and free of rot, but the operating parts or glass are no longer doing their job.
