Full Frame vs. Insert Window Replacement for Baltimore Rowhomes

What The Two Methods Actually Change

The two methods can both work well in a Baltimore rowhome, but they solve different problems. Full frame replacement removes more of the old assembly, while insert replacement preserves more of what is already there.

Full frame replacement means the contractor removes the sash, frame, trim, and often the old casing back to the rough opening, then installs a completely new window system.

With insert replacement, the old frame stays put, so the contractor is working inside a smaller footprint and not reopening the entire wall cavity.

That difference matters a lot in older Baltimore housing stock, where plaster walls, thick trim, brick openings, and past repairs can make the original window conditions hard to predict.

When A Full Frame Replacement Makes More Sense

What Affects Cost And Approval In Baltimore

In most markets, a full frame replacement costs more than an insert replacement because it involves more labor, more materials, and usually more finishing work.

What To Look For Before You Sign The Contract
