4 Warning Signs That Your Windows Need to Be Replaced

New installation windows can enhance your home in many ways, from improving energy efficiency to boosting curb appeal. On the flip side, old, failing windows can drag down your home’s appeal and comfort. Wondering if it’s time to replace your windows? Read on as we share the telltale signs that your existing windows are failing and ready to be retired.

  1. Your Energy Bills Have Spiked: The U.S. Energy Information Administration estimates that as much as 42% of an average home’s annual energy consumption is spent on indoor heating, with another 6% spent on indoor cooling. Inefficient windows allow unwanted heat loss during the winter and unwanted heat gain during the summer. When shopping for replacement windows, look for products like ours that are certified by ENERGY STAR®. Our windows help minimize unwanted heat gain and heat loss, thereby reducing your reliance on your HVAC system, which leads to lower energy bills.
  2. Your Windows Are Difficult to Open and Close: If your windows don’t operate as smoothly as they used to, your window frames or sashes may be warped or damaged. That means they won’t form a proper seal when closed, thus compromising your home’s energy efficiency. Our window replacement units feature Fibrex® frames, which are exceptionally resistant against warping and cracking, ensuring smooth operation all year round.
  3. You’re Seeing Condensation Inside the Glazing: If you notice condensation on the glazing, take a closer look. Condensation on the interior side of the window typically indicates a humid indoor environment and is often not a window problem at all. However, if the condensation is located between the glass panels, this means the seal around the panels has been broken. If the space was filled with an insulating gas, the panels may look like they’re pressing towards each other. This is a serious problem that requires window replacement.
  4. Your Living Space Is Dark and Gloomy: If you need artificial lighting inside your home in the middle of the day, you should consider replacing your windows with new units that admit more natural light into your home. Don’t worry about the sunlight fading your fabrics and furniture; our High-Performance™ Low-E4® glass features low emissivity (Low E) coatings that block unwanted UV and infrared rays, letting you enjoy as much natural light as possible without the downsides of heat gain and harmful UV rays.

"Adam and Ryan arrived on time and got right to work. They were very professional and so careful not to make a mess. Their work looked great and we were very pleased with the job they did. We were especially pleased that they finished earlier than expected. It all worked out very well and we are very pleased."
