The Main CHAP Questions Behind A Window Replacement Request

When CHAP evaluates a request, the focus is typically on what the finished window will look like from the public way.

Repair, Restore, Or Replace: How To Decide

In older Baltimore housing, especially prewar rowhomes, a window that looks tired is not always a window that needs to be replaced.

Repair tends to make sense when the wood is still sound, the opening is square enough to work with, and the original sash can be made energy efficient with weatherstripping, glazing repair, or better hardware.

Replacement becomes more reasonable when the frame is rotted beyond repair, the window has been altered repeatedly, or the original components are missing and no longer functional.

The more the new window matches the original form, the less likely it is to create problems with review.
