Old windows that have lost their seal can cause mold growth, which can lead to respiratory illness. The longer homeowners wait to replace leaky windows, the worse the problem becomes. New windows eliminate leaks, and they can also prevent condensation from forming on windowpanes, which contributes to air quality issues.

CR Ratings: Window Replacement

The primary benefit of Window Replacement is lower energy bills, because the improved insulation allows homeowners to keep their homes at a more comfortable temperature without having to run their heating and cooling systems as often. Energy-efficient windows can also help to reduce greenhouse gas emissions, which is good for the environment.

Another benefit of window replacement is a boost in home value, since the new windows will look better than the older ones and will be more attractive to potential buyers. In addition, a well-maintained home that is energy efficient and has attractive windows is more likely to sell quickly if the owners decide to move.

The cost of replacement windows varies depending on the type and features selected. For example, bay and picture windows, which extend outward from a room, are more expensive than double-hung and sliding windows. Specialty window features, such as a low-E glass and gas-filled panes that are ENERGY STAR certified, can also increase costs. Project-specific details, such as the location of the windows and whether they’re load-bearing, also affect cost. Finally, timing can impact price; spring and summer are peak window-replacement seasons, and prices may be higher due to contractor availability.
