As professional window cleaners, we've seen windows of every age from brand new, to over 100 years old. Over time, your windows may decay and eventually, you'll need to replace your windows. Windows may start to show signs of their age in several ways. Here are five of the most common ones.
Increased Energy Bills: If you've noticed that your energy bills have been increasing, it could be due to drafty or inefficient windows. Old windows slowly lose the inert gas between their panes and their energy conservation capability drops when this happens. Their seals also slowly degrade over time due to sun exposure and heat cycles.
Visible Damage: If you see visible damage on your windows such as cracks, rot, or warping, it may be time for replacement. Damaged windows can compromise your home's security and energy efficiency, and present a safety hazard to you and your family as they are easily broken.
Difficulty Opening or Closing: If your windows are difficult to open or close, it could be a sign that they're worn out or damaged. This can be a safety hazard, as it may make it difficult to escape in the event of an emergency.
Condensation: If you notice condensation or fogging between the panes of glass in your windows, it indicates that the seal has failed, the inert gas trapped between the panes has escaped, and it is time to replace your windows.
These are four of the most common signs it's time to replace your windows, but others may include hard water damage or etching, deep staining, and more. Windows need maintenance and eventual replacement just like every other item on your home but cleaning your windows frequently can help make your windows last for as long as possible.
