When planning for replacement windows in Los Gatos, CA, timing is an essential factor. Homeowners want to make sure they have gotten the most out of the life cycle of their old windows. But how do homeowners know when an old window has truly outlived its usefulness? Here are a few of the most common signs to watch for. One or more of these issues means it is time to get serious about new windows.

Moisture Leaks

Windows that leak water into the home are a huge red flag. Not only is it annoying to have to wipe up the drips during every storm, but guarantees water is seeping into the sills, walls, drywall, and more. Eventually, the leaks will lead to serious water damage and homeowners need to replace the windows as soon as possible.

Air Drafts

Windows that leak water also tends to leak air. This might not seem like a serious problem, especially in an area with a moderate climate. But in the winter and the summer, a leaky window can be a major problem for the HVAC system. All that energy goes to waste if hot or cold air continuously escapes outside. If energy bills are out of control, it might be time to take a closer look at the old windows. They are the most likely cause of energy leaks.


Moisture on the exterior surfaces of the windows is not a major problem. This type of condensation will come and go without any extra effort. This is because exterior condensation is caused by humidity and temperature fluctuations. It isn’t caused for concern. A bigger issue occurs when fogging gets trapped between the panes on the windows. This is a clear indication of seal failure on the old windows. The inert gas that helps insulate the windows leaks out and normal air replaces it. These windows no longer insulate as well as they were designed to and the energy losses could be significant. With fogging between the glass, it is time for new windows.

Difficult Operation

Many older windows get sticky and take more effort to open and close. This might seem like a minor nuisance, but it is important to keep in mind that some windows are egress windows. This means they need to function as an exit route in the event of an emergency. But if they do not open and close smoothly it could mean the difference between life and death. When windows are too old to open and close, then it is time for new windows.

Noise Pollution

Noise transference is another common problem for old windows. This has less to do with the age of windows and more to do with modern technologies that now help to block unwanted noise. This minor annoyance can become more of a concern in busy areas with a lot of traffic noise.
