If your uPVC window isn’t closing properly, it can be frustrating and lead to drafts, higher energy bills, and even security issues. However, the good news is that most common problems with uPVC windows not closing can be easily fixed with a few simple steps. In this article, we’ll explore the most common reasons why your uPVC window may not be closing and provide you with easy solutions to get your window back in top shape.
Worn or Damaged Hinges
One of the most common reasons why a uPVC window won’t close properly is worn or damaged hinges. Over time, the hinges that allow your window to open and close can become worn down, bent, or even break entirely. This can cause the window sash to become misaligned, preventing it from closing tightly against the seal.
To fix this issue, you’ll need to replace the damaged hinges. Start by measuring the length and height of your existing hinges, then purchase replacement hinges that match. Once you have the new hinges, carefully remove the window sash and replace the hinges, making sure to align the window properly before reinstalling it. This simple fix can often restore the proper closing function of your uPVC window.
Window Out of Square
Another common reason for a uPVC window not closing properly is if the window is out of square within the frame. This can happen if the window was poorly installed or if the glass is not located squarely in the sash. When a window is out of square, it can cause rapid deterioration of the mechanical parts, such as the hinges, and lead to drafts and air leaks.
To fix a window that is out of square, you’ll need to adjust the hardware, such as the hinges, and potentially repack the glass to ensure the sash is held square to the frame. This repair requires some specific skills and understanding of uPVC windows, so it’s best to have it completed by an experienced service engineer.
Failed Locking Mechanism
The third most common reason for a uPVC window not closing properly is a failed locking mechanism. The locking mechanism consists of three main parts: the handle, the gearbox, and the drive gear. If the window won’t lock, it’s likely that the gearbox unit has failed. Even if the lock isn’t broken, the drive gear and/or keeps may not be adjusted correctly, resulting in the window not sealing tightly when in the locked position.
To fix a failed locking mechanism, you may need to replace the gearbox unit or adjust the drive gear and keeps. This repair can be simple and may just require a service and adjustment by a competent DIY enthusiast. However, if you’re not comfortable with the repair, it’s best to contact a professional window repair service for assistance.
Temporary Fixes
If you’re unable to immediately repair your uPVC window, there are a few temporary fixes you can try to reduce drafts and air leaks:
- Apply blue painter’s tape over the cracks to block air flow
- Use duct tape or “gorilla” tape, but be aware that it may be difficult to remove later
- Stretch a clear plastic product over the entire window opening to act as an inside window seal
- Tie a length of rope or cord around the window handle, pull it taut, and secure it to a weight on the floor to keep the window shut
These temporary fixes can help reduce drafts and air leaks until you’re able to make a permanent repair to your uPVC window.
In conclusion, if your uPVC window isn’t closing properly, it’s likely due to worn hinges, the window being out of square, or a failed locking mechanism. By identifying the root cause and making the necessary repairs, you can restore your window to proper working order and enjoy a more comfortable, energy-efficient home. Remember, if you’re not comfortable making the repairs yourself, it’s always best to contact a professional window repair service for assistance.
