When there isnโ€™t visible damage, you might take your homeโ€™s windows for granted. They very well may be in great shape! However, if you arenโ€™t sure how old your windows are, you may not notice signs their condition is deteriorating. Learn about the expected lifespan of your windows and how to tell when itโ€™s time for replacement.ย 

How Long Do Windows Typically Last?

Residential windows typically last about 20 years, with some lasting up to 30 years. Taking good care of your windows will help extend this length past the 20-year mark. However, you should investigate your windows closely if they were installed more than 20 years ago to check that theyโ€™re still in good shape. Even if they donโ€™t last their full lifetime, youโ€™re in good hands with Window World of Joliet. Our windows are covered with a limited lifetime transferable warranty for your peace of mind.ย

How to Prolong Your Windowsโ€™ Lifespan

It makes sense to get your moneyโ€™s worth out of your homeโ€™s windows before seeking replacements. However, there comes a point when it makes more sense to replace than to continue to shore up poor-performing windows. As long as your windows arenโ€™t contributing to pesky drafts or higher monthly energy bills, you can continue to make the most of them. Extend the lifespan of your windows with these ideas: 

  • Clean Often: Simple but true, rinsing windows with a mild cleansing solution regularly keeps them in good shape. 
  • Caulk Cracks: Avoid water damage in windows or your home by caulking small cracks in seals as needed. 
  • Avoid Pressure Washing: While pressure washing clears your siding of dirt and grime, it can also damage the seals in your window frames.ย 
  • Replace Weatherstripping: Weatherstripping can crack or even break over time. However, if there are multiple problem areas, itโ€™s best to replace the entire window.

7 Signs Itโ€™s Time for Replacement Windows

There comes a point when repairing your windows simply doesnโ€™t make sense. Whether due to age or extensive yet necessary repairs, sometimes it makes more sense to upgrade to replacement windows. If youโ€™re noticing more than one of these signs, itโ€™s time to get in touch for replacements.ย 

  1. Visible Damage: Any cracks in panes could worsen or even break, leaving your home vulnerable.
  2. Drafts or Air Leaks: More than an inconvenience, drafty windows drive up your utility bills and decrease your homeโ€™s comfort.
  3. Higher Energy Bills: If your energy bills are higher without changes in your household usage, investigate your windows. Older models are not energy efficient.  
  4. Hard to Open or Close: Every window can have trouble opening and closing, but if youโ€™ve tried fixing it multiple times, itโ€™s time to replace.
  5. Worsened Allergy Symptoms: Seasonal allergens may come in through cracks in your seals. If youโ€™ve been sniffling more than usual, check your windows. 
  6. Condensation Between Panes: This indicates the seal between your panes has failed and the insulating gas inside has escaped. 
  7. No Sound Dampening: Hearing that lawn mower too clearly? Replace your windows for better sound dampening and restored peace.

Benefits of Replacement Windows

Deciding to replace your windows is a decision you shouldnโ€™t take lightly, but given the investment into your home (and its value), it will pay off in the long run.ย 

Improved Energy Efficiency

The technological advances in replacement windows, like our Low-E glass, make them energy efficient, keeping your home comfortable year-round. Your heated or cooled air wonโ€™t escape through cracks like older windows, saving you money over time.ย ย 

Increased Safety and Security

Older windows, especially with cracked panes or failing seals, can more easily compromise the safety of your home. With replacement windows, youโ€™ll have a stronger exterior that you can count on to protect your home and everything inside. 

Curb Appeal
