Locks with a problem

Many people put anti-burglar systems on their main gates and doors However, they tend to forget that windows are the most frequent targets for burglars. Faulty locks can cause draughts, let valuable heat escape and weaken the security of your home.

If your uPVC windows locks do not function, it is most likely that the lock mechanism is jammed. This usually occurs due to a slit in the gearbox component. This could cause the handle to turn 360 degrees, but not fully open. This is a frequent issue with uPVC casement windows, but can also be found in tilt and turn windows, and even sliding sash windows.

If this happens, you can release the lock by pressing the lever handle. This can help to unblock the gear box and allow the opening of the window. If this doesn't work then you might need to replace the entire mechanism of the window lock.


Most modern uPVC windows use espagnolette locks. They are a locking system inside the window that secures the window by using locking cams that resemble mushrooms that are inserted into the frame keeps. The handle turns on the gearbox, which activates the cams for either up or down movement. A common fault with these is when the spindle on the lock has been damaged which causes the handle to turn freely but not move the window open or close.

A damaged gearbox may cause your window to appear to be locked, but isn't actually. This could happen if the rods in the centre (sometimes known as crocodile teeth fixings) within the gearbox have been snapped off. If this is the case, Misty Glaze can supply and fit replacements for these rods in order to restore the function of your window.

Sticky Doors/Window

It's a nuisance to find doors and windows that don't close, but they may also indicate more serious structural issues. If you're having difficulty to open or close a window or door, it's important to seek help from a professional whenever you can. This issue can result from a variety of causes such as foundation settlement or an absence of support for the crawl space.

Windows and doors often get stuck due to humidity or an issue with the frame itself. When exposed to moisture, wooden frames may begin to warp. Even if the hardware looks good, this can make it difficult to open and close your frames. The wood swells when this happens and is pushed up against the hinges creating friction.

If your door or window is sagging in summer, try rubbing it with bar soap to decrease the friction. This will make it less swollen and could solve the issue temporarily. This solution may need to be repeated frequently during periods of high humidity.

Sanding the frame of the window or door to a smooth surface is a more permanent fix. This can be done by hand or with the power tool. A professional can also sand, paint or stain your frame or door to make it appear new again.

Rub some lubricating oils on a lint free cloth and then rub them into the hinges, handle mechanism and places where they go through frames (for instance, a window with sash). You can also take off the handles and wash them with warm soapy water to wash away any dirt or dust.

It is essential to speak with a professional if your uPVC windows and doors aren't functioning as they should. They can identify the problem quickly, and fix it in a short time.
