Full-Frame vs Insert Window Installation in Leesburg VA

How Full-Frame And Insert Window Installation Differ

The real split between these two methods is how much of the existing opening gets removed.

A full-frame job takes out the entire existing unit, including the frame, so the installer can inspect the rough opening behind it.

An insert window installation leaves the original frame alone and sets the new unit into that shell.

That distinction sounds simple, but it affects everything from insulation to labor time to how the finished window looks from the outside.

Homeowners often ask how much does window replacement cost in Leesburg VA, and the answer depends heavily on which method is chosen.

When To Choose A Full-Frame Window Replacement
