It's pretty easy to tell when wooden windows need to be replaced. The wood gets rotten, and in some cases, it even starts to chip away. But what if you have vinyl windows? Vinyl windows are known for being long-wearing, low-maintenance, and durable, but they do eventually reach the end of their lifespan and need to be replaced. Here are some signs your vinyl windows are due for replacement.

Moisture Between Glass Panes

One of the surest signs that your windows are failing is moisture between the panes. Look at each window closely. Do you see any drops of water or water vapor trapped between the glass? This water means that the seal between the vinyl and the glass has been compromised. Air is seeping in, and when the temperature changes, some of the moisture in that air condenses into water.

There are companies that will come dry out the windows' interior and reseal them. However, this service often costs as much as replacing the windows. So, unless your windows are new enough to be fixed under warranty, moisture between the glass panes generally means the vinyl window needs to be replaced.

Difficulty Opening and Closing

When a window becomes tough to open and close, this generally means that the vinyl is bent or bowing in someplace. This can happen as the vinyl window are put under strain in the same places again and again. Right now, you might just be struggling to open and close the windows, but before long, the vinyl might actually crack. Then, you might not be able to open or close the window at all. So, your best option is usually to have the vinyl window replaced before that happens.

Cracks and Chips in the Sash 

Another sign your vinyl windows are due for replacement is cracks and chips in the sash. If these cracks and chips are along the edge of the vinyl, they may not look like they're affecting anything too much. However, they are probably causing air leaks that are reducing your home's energy efficiency. The cracks can also grow larger at any point, and then they might start letting water leak in, too. Replacing a cracked or chipped window sash will save you money down the road.

If you notice any of the issues above, then your vinyl windows probably need to be replaced. Talk to a window replacement company near you.
