Common Issues with uPVC doors, windows, hinges and locks

While everyone recognizes a uPVC door and window as soon as they see one, do you know what it actually means? uPVC stands for plasticised vinyl chloride. It is strong and rigid when used in its original form. uPVC can be tough and maintenance-free. It is also long-lasting, making it a popular choice in homes. However we can offer some tips and tricks to help you deal with the problems.
Despite its resilience and strength, uPVC has been known to shrink in extreme weather conditions such as high heat or wet. Although it should not cause permanent damage to uPVC, its temporary problems can sometimes be frustrating and cause concern.

The most common problem for home owners is the expansion and contraction of uPVC in hot temperature. UPVC has been known to expand at 40°C by as much as 2.4cm in heat!

Waiting for the plastic to cool is the easiest solution. This allows the plastic to be returned to its original state. But, because of time constraints, this may not always work. To speed up the cooling process, spray the uPVC using cold water. If this fails, uPVC doors or windows have easily adjustable flag hinges. They are made to allow heat expansion and allow for adjustment when necessary. It is important to remember that the plastic will need to be adjusted back to its original location if it returns at normal temperature. If this happens again, you may need to consult a specialist.

Another issue is what we refer to as a door that has ‘dropped’. It is when the door is difficult to lock or catches on the frame when it closes. Although you may feel this is a sign of a new door or a broken lock, it usually means that the door needs to be adjusted.

Door can fall for many reasons, but most often it is because of:

Because of their sheer weight, especially windows or doors with glass, and the fact they are supported only on one side of a frame with hinges and not on the lock side (lock side), this can make it difficult for the hinges to support over a long period of time and cause them to eventually drop.
Wear and Tear: We have all hit a door once or twice in our lives and we know how damaging it can be.

Most doors and windows come with flag hinges. This means that they can be adjusted in any direction. However, older doors and Windows may have fixed hinges. This means that they cannot be adjusted up or down like flag hinges.

You can check to see if your glass or door is dropping by closing the door slowly. Then, look for the point where the edge touches the frame. The sign of a broken lock or rubbing on the bottom can be a tell-tale sign. You can adjust the hinges to your liking by looking at this. It is possible to resolve the problem by making a few adjustments.
