Fixing Drafty Windows and Condensation in Leesburg VA Winters

Why Windows Feel Drafty When The Weather Turns Cold

When a window feels cold in winter, the problem is often in the frame, sash, weatherstripping, or installation, not just the pane. In Leesburg VA winters, that matters because a house can feel uncomfortable long before the thermostat shows a major problem.

The signs are often subtle at first, then become easier to ignore only after the bill arrives. If one window is much worse than the others, that usually points to failed weatherstripping, a bad seal, or a rough installation detail.

What Condensation Is Telling You
