Custom Window Sizes for Older Baltimore Rowhouse Openings

Presented by @awningwindowsyla333

Why Older Rowhouses Rarely Match Modern Window Sizes

If you have worked on enough Baltimore rowhouses, you learn quickly that the opening on paper rarely matches the catalog size on the shelf.

What looks like a simple 3-foot by 5-foot window from the street may actually be a slightly irregular opening with old framing, layered trim, and a few surprises hidden behind the finish work.

That is where custom window sizes for older Baltimore rowhouse openings come in.

One of the most common mistakes is assuming a standard-size unit can be forced into a handmade opening with enough caulk and trim.

What Contractors Look For Before A Custom Window Is Ordered

In older homes, the inside opening and the exterior opening may not tell the same story.

An experienced window replacement company can confirm the cause with a quick inspection.
