How to Fix Drafty Windows in Older Knoxville Homes

In older Knoxville houses, drafty windows tend to reveal themselves on the days when the weather turns fast, especially when a cold front rolls through and the rooms near the glass feel noticeably different from the rest of the house. It does mean the window assembly is letting conditioned air escape and outside air work its way in.

Homes built decades ago often settle, shift, and dry out in ways that leave small gaps around the frame, sash, or trim. The difference between a cheap patch and a lasting repair is usually knowing exactly where the draft starts.
