Why are my windows drafty and will new replacement windows resolve my problem?
Drafty windows and air infiltration could have several causes. Improper installation is often the culprit but not always. If the windows were improperly installed, the defects can normally be corrected without removing or replacing the window.

Proper caulking and flashing should prevent perimeter air leakage. However, if the installation twists or racks the window frame causing the sash weatherstrip not to be able to seal the sash to the frame, removal of the window to correct the problem may be necessary. You can determine whether the air is coming in at the joint between the frame and the house or the joint between the sash and the frame. Hold a lighted candle or lighter in front of each joint when the wind is blowing and slowly move it along the joint. If the flame flickers strongly or goes out, the joint is probably leaking.

If the leak is between the frame and the sash and the window has been installed square, plumb, level and is not twisted or racked, the problem may be construction of the window or window design. If your windows are not efficient in your climate and particularly if it does not have insulated glazing, the air may not be leakage but simply cold room air flowing down the surface of the window.

When should I consider replacing my windows?
You should consider replacing your windows if:

• Your windows aren't energy efficient.
• Your wood frames are rotting.
• You get excessive amounts of condensation, fading of furniture and draperies.
• You are tired of painting and staining.
• You feel drafts while sitting near your current windows.
