How to Adjust uPVC Door Hinges the Right Way

If you’re having problems with your uPVC door, the chances are that it’s because the hinges aren’t adjusted correctly. This can be a real pain to fix, but it’s not impossible. In this article, we will walk you through the process of adjusting your uPVC door hinges so that they work properly again.

Why is your door not closing properly?

The first thing you need to do is figure out why your uPVC door isn’t closing properly. There are a few different reasons why this could be happening:

The hinges are bent or damaged: This is the most common reason why uPVC doors stop working correctly. Over time, the hinges can become bent or damaged, which prevents the door from closing properly.

The door frame is not level: If the frame of your door is not level, then the door will not close properly. This is because the hinges need to be level in order for the door to close correctly.

The strike plate is misaligned: The strike plate is what the latch on your door latches onto when you close it. If this is misaligned, then the door will not close properly.

The latch is damaged: If the latch on your uPVC door is damaged, then it will not be able to catch onto the strike plate correctly. This will prevent the door from closing properly.

Once you know why your door isn’t closing properly, you can start to adjust the hinges.

How to check a door’s alignment?

The best way to check the alignment of your uPVC door is with a level. Place the level on the top of the door, in the middle. Then, open and close the door to see if it moves. If it does, then you need to adjust the hinges.

If you don’t have a level, you can also use a tape measure. Measure the gap between the door and the frame at the top, middle, and bottom. If the gaps are different, then the door is not level and you need to adjust the hinges.

What type of hinges do uPVC doors have?

Most uPVC doors have two types of hinges: butt hinges and flag hinges. Butt hinges are the most common type of hinge used on uPVC doors. They are located at the top and bottom of the door, and they allow the door to swing open and closed. Flag hinges are less common, but they are often used on heavier doors. They are located at the top and bottom of the door, and they allow the door to slide open and closed.

If you’re not sure what type of hinge your uPVC door has, you can usually find out by looking at the manufacturer’s website.

What do you need to adjust a uPVC door?

In order to adjust a uPVC door, you will need:

    • A screwdriver
    • A drill
    • A level or a tape measure
    • Allen key
