Some signs that it’s time to consider replacing your windows are obvious, while others require taking a closer look. Here’s our list:

•• Windows difficult to open/close - Although this can also be a sign of structural settlement, it is usually due to age.

•• Window locks, springs or operators broken - Damaged springs mean a single-hung window won’t stay open by itself, broken locks and operator handles accumulate with age.

•• Drafts or warm/cold area around windows - Single-pane windows and leaks around the frame and sash can make it uncomfortable near an old winow, especially in winter.

•• Window frames warped or rotted - Wood is susceptible to rot if surface finish deteriorates and vinyl prone to warping as it ages.

•• Haze buildup at double-pane windows - When double-pane windows lose the inert, insulating gas between panes, the glass begins to cloud over. See our article What is causing a foggy haze on my windows? for more on this.

•• Higher energy bills - Leaking, older windows can cause energy bills to creep upward.

    New windows also increase both the curb appeal and interior views, along with the value of your home when it’s time to sell.
