How To Adjust UPVC Door Hinges 

Firstly, what does UPVC stand for?

Unplasticised Polyvinyl Chloride is an ideal door material due to its strength and lightweight nature. A decisive advantage of UPVC doors is their ease of adjustment.

If you’re struggling with a door that isn’t properly aligned or is catching on another edge, understanding how to adjust uPVC door hinges can make this a stress-free maintenance job.

This article will walk you through adjusting the hinges on a uPVC door, whether your adjustments are horizontal, vertical, or depth-related.

Understanding Hinge Types on UPVC Doors

Before diving into the adjustments, you need to check the type of hinges on your UPVC door. These can be typically one of three types: Butt, Flag, or Rebate hinges.

When you’re just grasping how to adjust UPVC door hinges, identifying them and understanding how they operate is essential.

Butt Hinges

Butt hinges, sometimes known as pencil or cylinder hinges, are standard on older uPVC doors. They provide little or no adjustability because they comprise two leaves, one attached to the door and the other to the door frame.

A pin is typically inserted through the top of the one attached to the door frame and into the one attached to the door.

Flag Hinges

Flag hinges are found on more modern uPVC doors, named due to the rectangular shape of the part attached to the door resembling a flag.

They offer you the most controlled adjustments, allowing changes laterally, vertically, and in terms of compression (moving the door closer and further from the door jamb).

Rebate Hinges

Rebate hinges are similar to butt hinges, but the hinge leaf (the part that attaches to the door) fits snugly against the door sash.

So when you close the door, the hinge is hidden. Typically, you can adjust them laterally and vertically.

What Tools Do You Need for uPVC Door Adjustment?

There is no need to raid your tool shed. You need three simple tools to learn how to adjust upvc door hinges. 

  • A flat-head screwdriver
  • A Philips head screwdriver
  • Allen keys (a hex key) are usually a 5mm one.

Adjusting Butt Hinges on a UPVC Door

Butt hinges can often be changed laterally by up to 2mm. If your hinge has two Phillips screws on the side, you can obtain sideways movement by turning the top or bottom screw.

An Allen key can be used to make vertical adjustments on the adjustment at the top of the hinge.

If the hinge has a grub screw in the centre, it must be released before adjusting the pin since it holds it in place.

Adjusting Flag Hinges on a UPVC Door

When making adjustments, flag hinges allow the most control. You may need to remove the plastic cap over the hinge to access the adjustment screws.

Once you have access, you can use an Allen key to modify the screws that regulate the height, lateral movement, and compression.

Begin by turning 1-2 complete rotations, then test the difference in the adjustment and turn in increments until the correct position is obtained.

Adjusting Rebate Hinges

Rebate hinges work in the same way that butt hinges do. They have top and bottom pins frequently covered by a cap that you must remove to gain access.

Once you’ve gained access, unscrew the grub screw keeping them in place and adjust with an Allen key. Adjust the screws on the hinge’s side for lateral side-to-side movement.

How to Stop Draughts by Adjusting uPVC Doors

Due to regular or excessive use, UPVC doors can become misaligned over time, resulting in draughts. To draught-proof a UPVC door, adjust the latch or hinges to fit the door appropriately in the frame.

Pulling the handle on your UPVC door will rattle if it is loose in the frame.

You can also adjust the strike plate by releasing the screws in the plate and door frame and sliding it towards the door’s entrance to tighten the fit or towards the inside of the home to loosen the fit so the latch can catch in the strike plate.

Adjusting a Dropped UPVC Door 

If your UPVC door height has dropped towards the handle side, you can lift it by using an Allen key on the screw at the door side of the hinge.

Begin by turning 1-2 rotations clockwise with the door closed, then try to see whether it still drags. Adjust the hinges so the door opens and closes smoothly.

Adjusting uPVC Door Height and Compression

If the door has dropped or needs to be higher in the frame, use an Allen key to adjust the screw controlling the vertical movement of the hinge.

If the door is set back from the frame in the top or bottom corner, tighten the fit by rotating the compression adjustment screw, usually the bottom screw.

How To Adjust UPVC Door Hinges from Side to Side

If your door needs to be adjusted from side to side, you can do this by adjusting the lateral adjustment screw. This will move the door closer or further away from the side jamb.

When Adjusting the Hinges Doesn’t Work

If you’ve adjusted the hinges and still can’t get the door to fit correctly, there could be a hinge problem.

In this situation, you may need to replace the hinges or contact the manufacturer to determine if the door is still covered under warranty.

It’s important to note that a misaligned door will shorten its lifespan due to extra wear and tear and lower your home’s energy efficiency.

Considering a New uPVC Door

If you’ve tried all these adjustments and still can’t get the door to fit, consider a new UPVC door.

Modern uPVC doors are hard-wearing, durable, and secure and come with a 10-year guarantee for installation and a lifetime guarantee for discolouration of profiles.

How To Adjust UPVC Door Hinges FAQ’s

Why is my UPVC door not closing correctly?

Safety is the primary goal when ensuring your UPVC door is functioning well. If you notice that your door is getting more challenging to open and close, numerous causes could be blamed.

First and foremost, a potential drop in your door, which frequently occurs when the hinges become loose, is a regular cause of this problem.

Second, moist or humid conditions can impair your door’s ability to close properly. Door frames may expand or contract during periods of intense heat or excessive moisture, causing issues with door closure.

Lastly, doors can occasionally become slightly misaligned for properties under two years old due to the minor shifts in your home’s structure as it settles.

Why is my door rubbing on the bottom of the frame?

If you notice bent hinges on your door or have reason to assume that this is the source of the door’s friction against the frame, you may need to realign or replace the hinges.

If the hinges are not bent but rather slack within the frame, you may be able to solve the problem by tightening the screws on the door to ensure it fits squarely within the frame. 

Why do my UPVC doors stick when I open them?

The most common cause of a door sticking is expansion, which can be caused by various variables depending on the material used for your door.

Increased temperatures can cause swelling and expansion in uPVC doors and many other types of composite doors.

How can I tell if my front door is UPVC or composite?

UPVC doors are made of plastic, whereas composite doors are made of materials tightly crushed and glued together under great pressure.

In terms of thickness, composite doors outperform uPVC doors, measuring 44mm versus 28mm for uPVC doors.

How do you remove UPVC door hinge pins?

The procedure is simple:

  1. Protect both your hands and the door frame.
  2. Position the tool directly over the protruding hinge knuckles, making sure the tool’s pin meets the bottom of the hinge pin.
  3. Pound it gently with a hammer to release the pin.


In conclusion, understanding how to adjust uPVC door hinges can prolong the life of your door, improve its energy efficiency, and prevent draughts.

Regular checks and minor adjustments as needed can prevent these issues from becoming more extensive, more troublesome jobs in the future.
