Drafty Windows: Common Causes and Fixes for Virginia Homes

Why Windows Start Letting Air Through

A drafty window is not always a failed window, but it is always a clue that air is moving where it should not.

Other times, the trouble runs deeper, especially in older houses where frames have settled, caulk has failed, or the original window design was never a good match for the home.

Virginia weather makes those weak points easier to notice.

The Problems That Show Up Most Often

A better-rated window cannot compensate for a sloppy install, and a modest window can perform well when it is fitted and sealed properly.

A few signs usually point toward replacement rather than another repair:

• High energy bills tied to rooms that are hard to condition

That is especially true in homes with original windows that have already been repaired once or twice and still do not hold a seal.
