Fixing Drafty Windows and Condensation in Leesburg VA Winters

Why Cold Air Finds Its Way Through Older Windows

A drafty window is not always a sign that the glass itself has failed. Here in Leesburg VA winters, even a small air leak can make one room feel noticeably colder than the rest of the house.
