Well kept house windows can significantly enhance the appearance and value of your home. If you buy replacement windows, they'll last about 30 to 40 years with proper maintenance, according to Building Operating Management magazine. The following tips will help you have energy efficient windows that last longer.

1.      Clean glass, sills, tracks, and frames. Remove dead insects, dirt, and debris from windowsills and tracks.

3.      Replace weather stripping. For more energy efficient windows that seal properly, use surface mounted or concealable weather seals that come in a variety of materials.

5.      Insulated windows may need to have the glass replaced if the seal begins to fail and you see a fog between the two panes. Replacing the glass will give you more energy efficient windows.

6.      Fix hardware. Check sash locks to make sure they work and replace if necessary.

7.      Lubricate windows. Energy efficient windows close properly souse a lubricant on the tracks to keep house windows from sticking.

8.      Repair screens. Patching holes allows less air to pass through, giving you more energy efficient windows.
