Top Reasons to Replace Old Windows Before Winter in Knoxville

Cold Weather Exposes Weak Windows Fast

Old windows usually get more attention once the first cold snap rolls in, because that is when the weak spots start showing up in a real way. A window that seemed "good enough" in October can suddenly feel drafty, rattle in the frame, or leave the room unevenly heated once temperatures drop.
