Over an extended period of time and use, you may find that your uPVC door drops, resulting in a door that drags ever so slightly or allows draughts to enter your home. The common cause for this is hinges which have become loose. Checking the hinges of your uPVC door is good practice, and will allow you to prevent these problems impacting your door over time. With our guide, you will be able to adjust the hinges on your uPVC door safely, correctly, and efficiently.

Please note, before you attempt to adjust the hinges on your door you should first check that you have a manufacturer’s warranty or installer’s warranty.

Identify your hinges

There are three main hinge types that you’ll likely find within your uPVC door. These include:

  • A flag hinge

You are likely to find flag hinges on newer uPVC door styles. You’ll find that a hinge of this type will allow you the most control when it comes to adjusting the positioning of your door.

  • A T-flag hinge

When adjusting these hinge types, you will be able to make lateral and vertical adjustments to your uPVC door.

  • A butt hinge

You’ll likely find butt hinges on older uPVC door types. Unfortunately, depending on their age, they may only offer you minimal control over adjusting the door.

What you’ll need to adjust your hinges

Each of these hinge types will require their own adjustment method. However, you will still need the same set of tools. This includes:

  • A flat head screwdriver
  • A Philips head screwdriver (with edges in the shape of a cross)
  • An Allen key

Adjusting your hinges

It is important to note that the adjustment screws in your door may be located in slightly different locations, depending on your uPVC door manufacturer. Studying the door will allow you to confirm which screw you are currently operating, allowing you to make the correct decisions to reposition effectively.

How to adjust flag and T-flag hinges

The lateral adjustment screw will most likely be located behind a plastic cap over the hinge, this will allow you to adjust the door horizontally. To remove this, you will need to use your Phillips screwdriver to loosen the screws on the inside of the hinge, before being able to remove the cap. You may require the assistance of your flathead screwdriver for this.

Your height and compression screws will likely be hidden by caps in the bottom of the hinge and will require the same process.

To adjust the screws, use your Allen key and rotate fully once or twice clockwise. Observe the difference that has been made to the position of the door and adjust as needed.

How to adjust butt hinges

You might find a grub screw in the centre of your hinge, and this must be loosened before adjustments are made. This is because the screw will hold the pin in place.

To adjust laterally, you will need to adjust the two screws on the side of the hinge with your Phillips screwdriver, This will provide you with horizontal movement.

Removing the cap on the top of the hinge will allow you to insert your Allen key and adjust the butt hinge vertically.
