How to Order Custom Window Sizes for Historic Baltimore Homes

Why Historic Baltimore Houses Rarely Fit Standard Window Sizes

If you live in a rowhouse, townhouse, or older detached home in Baltimore City, you have probably already seen that no two windows are quite the same once the trim comes off.

In older Baltimore properties, the window opening may be out of square, the sill may have shifted, or prior repairs may have changed the true rough opening enough that a stock unit no longer makes sense.

A proper custom order can protect the historic character of the home while also solving practical problems like air leakage, sticking sashes, and uneven reveals.

An experienced company can confirm the measurements with a quick site visit.

What To Know Before You Place A Custom Window Order

Start with careful measurements taken at the top, middle, and bottom of the opening, because old frames are rarely perfectly true.

When a frame is not perfectly square, the narrowest measurement often sets the size you can safely order.

Many bad orders happen because someone measured the old sash instead of the real opening that the new unit will occupy.

Before you place an order, jot down a few details that will save time later:

Exact width and height at multiple points The depth of the frame and the wall thickness Whether the sill is flat, damaged, or sloped The window type, including double-hung, casement, or fixed Any trim, casing, or masonry details that affect fit

In a historic district, size alone is not enough, because proportions, muntin patterns, and exterior sightlines can affect approval.

Historic District Approval And Permit Issues To Watch

If the frame is too deteriorated, a custom replacement may be the better route, especially when the opening is irregular or the old unit has already been altered.

How To Avoid The Common Mistakes
