Permits, Historic Review, And What Usually Gets Flagged

How To Choose Between Restoration And Full Replacement

A lot depends on the condition of the existing frame and sash. If the wood is sound, the sill is stable, and the window can still be made weather-tight, repair or restoration may be the better move.

Replacement starts to make more sense when rot, warping, failed seals, or repeated patchwork repairs have pushed the window beyond practical repair.

One of the biggest mistakes in older Baltimore homes is choosing the wrong product for the opening. Standard sizes do not always work. Custom window sizes for older Baltimore rowhouse openings are common, and forcing a near-fit can create draft problems, water intrusion, and awkward trim work.
