Full Frame vs Insert Window Replacement for Baltimore Rowhomes

What Changes Between Full Frame And Insert Replacement

In a Baltimore rowhome, the decision between full frame and insert replacement is rarely just about the glass. It is about the wall, the trim, the old frame, and how much of the original opening is still sound.

Insert replacement leaves the old frame behind and installs a new unit within that existing structure.

When Insert Replacement Makes Sense
