4 Common Vinyl Window Problems

If you’re looking for replacement windows, one of the things you’ll need to think about is the window frame material. There is a wide variety to choose from, such as aluminum and wood. For many homeowners, the vinyl window is a popular choice. However, there are some common problems you need to consider before choosing vinyl windows for your home. 

Vinyl Window Problems

1. Warping

A warped window can become bent or twisted out of shape. Warping can have a negative impact on the appearance and energy efficiency of your window. Vinyl window frames are susceptible to warping, especially if they are exposed to sunlight for a long period of time. When heat builds up, it can eventually soften the vinyl window. As the vinyl begins to sag and distort, it may become impossible to open and close them properly.

2. Stripped Cranks

Homeowners who prefer energy-efficient window styles turn to vinyl casement and awning windows. To open and close these windows, you’ll need to use window cranks. However, many homeowners usually over-tighten the cranks, believing it will result in a tighter seal. They do not realize that locks and latches pull the sash tight against the frame. Tightening the window too much can also strip the crank. 

3. Seal Failure 

Your window contractor may tell you that vinyl windows are not as rigid as other materials, especially on larger window installations. It can expand and contract seven times as much as the window glazing. This puts a lot of strain on window seals and may eventually trigger the windows to crack. Seal failure is a particular concern in areas with extreme fluctuations in weather. 

4. Less Viewing Area 

If you want to have a bigger view of the outdoors, you may want to avoid vinyl windows. In comparison to other frame materials, vinyl window frames are wider. You might not notice the difference on larger windows, but it has a significant impact on smaller openings. A smaller viewing area also means less light, preventing you from benefiting from more daylight from your new windows.

"We are very pleased with our new windows and sliding door. The crew showed up when they were scheduled and had to work through snow drifts. They all were very professional, efficient and respectful. They made sure we were knowledgeable about how to use the windows and had us inspect everything before they were done. Great job!!"
