Fixing Drafty Windows and Condensation in Leesburg VA Winters

Why Windows Feel Drafty When The Weather Turns Cold

Cold air around a window usually means the whole assembly is letting heat escape somewhere. In Leesburg VA winters, that matters because a house can feel uncomfortable long before the thermostat shows a major problem.

The usual culprits are not mysterious, they are the same ones installers see again and again. Gaps in old caulk, brittle weatherstripping, warped sashes, loose locks, and frame movement all let conditioned air escape.

Others notice it when a curtain moves, a candle flickers, or the floor near the window feels colder than the rest of the room. If a window has always felt cold, the issue may be basic air leakage.

When Foggy Windows Point To A Bigger Problem

Moisture on the room side of a window can be normal when indoor humidity is high and the glass surface is cold. When warm, damp indoor air meets a cold pane, the result is often surface condensation.

A window that only fogs on the coldest mornings may be dealing with humidity levels, while a window that stays cloudy between the panes is telling a different story. That distinction saves time and prevents unnecessary replacement.
