7 Signs It’s Time To Replace Your Windows

Windows do more than provide natural light and a view—they help regulate your home’s temperature, energy efficiency, and security. But over time, windows can wear down, leading to costly problems. So, how do you know when it’s time to replace your windows? Here are seven warning signs you shouldn’t ignore. 

  1. Your Home Feels Drafty 

Do you feel a chill near your windows in the winter or warm air leaking in during the summer? Drafts indicate worn-out seals, cracks or inefficient glass, all of which make your home less energy-efficient.

  1. You See Foggy or Condensed Windows 

Double-pane windows are designed with insulating gas between the glass. When the seal fails, condensation can form between the panes, making your windows appear foggy. This reduces insulation effectiveness and can drive up your energy bills.

  1. Your Energy Bills Keep Climbing 

If your heating and cooling costs have steadily increased despite no major changes in usage, you may need to replace your windows. Old or single-pane windows struggle to retain indoor temperatures, forcing your HVAC system to work harder. 

  1. Opening & Closing Windows is a Struggle

Windows should open and close smoothly. If they’re sticking, jamming, or require force to operate, warping, rusting, or faulty hardware could be the cause. This not only reduces functionality but also poses a safety risk in emergencies.

5. Outdoor Noise Feels Louder Indoors

If you hear every passing car or barking dog, your windows may have poor sound insulation. Modern replacement windows with double or triple panes can significantly reduce noise pollution, making your home more peaceful.

6. You Notice Visible Damage

Signs of damage—like peeling paint, cracked glass, or rotting window frames—aren’t just aesthetic concerns. They can lead to structural issues and decrease your home’s value.

7. You See Water Stains or Mold

Water leaks around your windows can lead to mold, mildew, and interior damage. If you see discoloration, peeling wallpaper, or warped wood near your windows, it’s time to act before the damage spreads.

Hear From Our Customers

This was a great crew to work with. Both the original install manager we worked with (Jay) and the install team (Daniel, Mason, Tony, Ethan, and Jose). Everyone was very professional and knowledgeable. They answered all my questions and the end result on the house is great. In 3 days they replaced an old bay window with a new bay window, a set of french doors on the patio with a sliding patio door, and our old front door with a new front door and storm door.

I cant express how happy we are with choosing Andersen for our window installation. Our sales representative was knowledgeable with product and answered any questions we had without hesitation. I did also fill out a survey that was sent in an email, but sadly I failed to personally name the two gentlemen that performed the actual installation. Barrett and Francisco were our guys, and let me tell you, they were outstanding!!! They did Excellent work and were professional as well as efficient and made this a smooth, none evasive process for us. I strongly recommend this company and these installers to anyone in need of windows!!! My husband and I could not be more pleased we chose Andersen for replacing our windows!!!

Jason and Brett did an awesome job installing our doors. We had separate installers a month earlier for our windows who also did a fantastic job. They were all very professional and cleaned up almost better than the area looked before the installation! Since these were both jobs that took more than one day the installers were great at keeping us informed on the status of where the project was at along the way.
