WHEN SHOULD I REPLACE MY WINDOWS? – Courtesy of Andersen Windows

Knowing when to replace your home’s windows isn’t always as clear as it may seem. If your home is older than 15 years, it’s probably a good time to check and make sure your windows are still operating correctly. For instance, do you have trouble opening or closing your windows? Do you consistently find moisture on your windows’ interior? Just like your washing machine, refrigerator, or roof shingles, over time, your windows and doors need to be replaced. To help you through the replacement process, Andersen provides tips and solutions to help determine if the time to replace and upgrade is now.

 
4. DO YOUR WINDOWS LEAK WATER OR LET IN TOO MUCH AIR IN THE WINTER OR SUMMER MONTHS?

The weather conditions outside your home should not appear on the inside—a good sign that your windows need to be replaced. Inefficient windows can leak, allowing water to come into your house both in front of and behind the walls—a leading cause of mold and mildew in homes. Old, worn-out windows or patio doors often leak air, resulting in high energy bills during peak heating and cooling months. The glass may be loose or the seal between the sash and frame may have weakened. Andersen recommends replacing old single-pane windows with new windows that feature dual-pane low-E glass for substantial energy savings. You’ll see the cost for replacing failing windows is often diminished by overall household energy cost savings. Remember: if the weather outside is coming inside, you’ve got a problem.
