How do you fix a uPVC window that won’t close?

uPVC windows that won’t close can lead to a host of issues. From draughts making the room cold and condensation causing mould, it’s important to fix the issue as quickly as possible. There are a few common reasons why uPVC windows won’t close, and the fix is slightly different for each. 

Why won’t my window close?

First, you need to identify why your window won’t close. Here is a quick checklist to get to the root of the problem: 

The window has dropped 

It’s natural for uPVC windows to sag slightly with age – they are pretty heavy, after all. However, if they drop too much, they can become hard to open and close without force. 

Check if the window is level with the frame or letting in sunlight through the top seam. 

The lock is loose 

With the window closed, slide a credit card between the locking mechanism and the frame. If it’s easy and can wiggle, the lock is loose and needs tightening. A loose lock will stop the seal from working properly, which means you’ll get condensation and draughts. 

The hinges are wearing

With the windows closed, see if there’s a gap between the glazing and the frame on the hinge side. If there is, your hinges aren’t pulling the window tight to the seal anymore. 

How to fix a uPVC window that won’t close

Once you’ve identified the issue, there are some quick window repairs that will ensure your window closes properly again. 

Your window has dropped

The glazing usually needs to be removed to fix a window that has dropped, so it’s best to leave it to the experts. We’ll use specialised packers to adjust the window and make sure it lines back up. Once done, the glazing can be reinserted, and the window will close effectively. 

The lock is loose

Adjusting the lock is easy enough to do with an Allen key. Open up the window so you can see the mechanism that moves up and down when you use the handle (known as Cams). These can be tightened with an Allen key to tighten the lock. 

Adjust it gradually and re-check to see when you’ve tightened the lock enough. 

The hinges are wearing 

Old hinges that aren’t supporting the window anymore usually need to be replaced. To do this, the old ones need to be removed, the window taken out, and new ones installed. 

This is another tricky job if you’re not a window expert, so it’s best to leave it to the pros to get the best results.
