The average lifespan for windows is 15 – 20 years, so if your home was built prior to 2007 then chances are good it’s time to start planning for window replacements. But aside from home age or obvious signs like cracked panes, how do you know that your home’s windows need to be replaced? Below are the tops 5 signs to look for:

  1. High Energy Bills

Have you noticed higher than normal energy bills? Does it seem like it’s difficult to maintain a comfortable temperature inside your home? Older single-pane windows, especially ones with wooden or aluminum frames, are prone to leaks which result in the cooling from your air conditioner going to waste.

Unlike modern, Energy Star rated windows, older windows lack energy-efficient features such as:

  • Low-E Glass: Window pane glass that is engineered to minimize unwanted heat from sunlight and UV rays from getting into your home
  • Vinyl Frames: Unlike wood or old aluminum frames, vinyl window frames are specifically designed to trap and repel unwanted weather and outside temperatures

Depending on the size of your home, replacing your windows could save you anywhere from $500 to over $2,000/year in decreased energy bills.


  1. Operational Issues

Does it feel like you need to be a professional body builder to open your windows or sliding glass doors. Your windows and doors should open effortlessly, so if it’s a struggle then this is a sign that they are painted shut or the frame has swollen overtime and they need to be replaced.


  1. Damage

Broken or damaged window panes, seals, or frames can be an obvious sign it’s time to replace your windows. Older frames, especially made out of wood, are prone to decay, cracking and chipping, impacting overall window integrity, appearance and performance.


  1. Outdoor Noise

Outside noise can be annoying and distracting, especially when you’re trying to get a good night’s sleep. If what is happening outside your window seems as if it’s occurring inside of your home, this is a good sign it’s time to upgrade your windows. If you start to hear neighbors chatting, cars, traffic noises, and dogs more clearly than before, it’s a sign your windows need to be replaced.


  1. Condensation

Are you noticing condensation or moisture build-up on your window panes? Foggy windows indicate that your seals are damaged and the windows are no longer airtight.
