Comparing Repair and Replacement for Double-Hung Windows in DC

What A Problem Window Is Telling You

A double-hung window does not usually fail all at once.

Small mechanical problems, especially on wood windows, are often worth fixing because the frame, sash, and glass may still have a lot of life left.
