If your uPVC window won’t close properly, it can lead to drafts, moisture buildup, and even security issues. Fortunately, there are several ways to fix a uPVC window that won’t close, from adjusting the locks to replacing worn-out hinges. In this comprehensive guide, we’ll walk you through the most common causes of uPVC window closure problems and provide step-by-step solutions to get your windows functioning smoothly again.
Before you can fix a uPVC window that won’t close, it’s important to identify the underlying cause of the problem. Some of the most common reasons why uPVC windows won’t close include:
One of the most common reasons why a uPVC window won’t close is a loose or misaligned locking mechanism. To fix this issue, you’ll need to adjust the locks using an Allen key. Here’s how to do it:
If the locking mechanism is broken beyond repair, you may need to replace the entire handle. To do this, gather a flathead screwdriver, Phillips screwdriver, and measuring tape. Pop off any screw caps, unscrew and remove the handle, and measure the length of the spindle protruding from the underside. Order a new handle online with the correct spindle size and install it.
Over time, the hinges on your uPVC window can become worn or damaged, causing the window to sag and preventing it from closing properly. To fix this issue, you’ll need to replace the hinges. Here’s how to do it:
If the window still doesn’t close, you may need to adjust the hinges on both sides. Loosen the screws on the problematic side, lift the window slightly, and tighten the screws again. This should help realign the window and allow it to close properly.
If the hinges are severely damaged, you may need to replace them entirely. There is a wide range of window hinges used in the UK, and most are still manufactured, so replacing just the hinges is often the most cost-effective solution.
If your uPVC window won’t close because the frame is misaligned or warped, you may need to reposition the glazing. This is a more complex task that is best left to the professionals, as it involves removing the glazing, adjusting the frame, and reinstalling the glass.
A misaligned frame can be caused by poor installation or frequent use over time. Adjusting the hinges and repacking the glass can help realign the frame and allow the window to close properly.
Sometimes, a uPVC window won’t close because of debris or dirt buildup in the frame or around the seal. To fix this issue, simply clean the frame and seal using hot soapy water and a toothbrush to remove any grit or grime. Be sure to work the mechanism back and forth to ensure all the dirt is removed.
Once the frame and seal are clean, apply a small amount of silicone-based lubricant to the moving parts to keep them functioning smoothly.
While many uPVC window closure issues can be fixed with some DIY work, there are some cases where it’s best to call in a professional. If you’re unsure about the cause of the problem or don’t feel confident in your ability to fix it, it’s always better to err on the side of caution and call in an expert.
A professional window repair service will be able to diagnose the problem quickly and provide a reliable solution. They may also be able to offer additional services, such as window replacement or upgrades, if your existing windows are beyond repair.
In conclusion, a uPVC window that won’t close properly can be a frustrating and potentially costly problem, but it’s one that can often be fixed with some basic DIY skills. By identifying the underlying cause of the issue and following the steps outlined in this guide, you should be able to get your windows functioning smoothly again in no time. Remember, if you’re unsure or don’t feel confident in your abilities, it’s always best to call in a professional for a reliable and long-lasting solution.
