This manual explains how to adjust an uPVC door’s height to prevent catching on the ground and how to adjust an uPVC door to eliminate draughts. accompanied with illustrations and videos that may be used to determine the types of uPVC door hinges you do have and how to modify them.
Do you have a door made of uPVC that catches on the floor or one that rattles in its frame and lets draughts in?
A uPVC door dropping or becoming loose in the hinges over time is relatively typical due to regular use, being opened and closed. It’s best practise to regularly inspect the hinges and make any necessary modifications to maintain your door fitting tightly.
The videos show how to adjust your uPVC door, and the pictures below illustrate the distinctions between a Butt hinge, T Hinge, and a Flag hinge.
Check to see whether you have a manufacturer’s or installer’s warranty or guarantee before attempting to alter your uPVC door.

How to determine whether your door is out of level
Check the location of your door’s alignment issue first.
Are the door’s corners’ mitres in alignment with the door frame’s mitres?
Use a spirit level on the top of the door to check the level of the door.
Open the door just a little bit, and at the lock side, check to see if the gap is constant all the way up and down the door and frame.
Is the door bent or out of square?
Low-quality uPVC doors may warp. Your door is probably warped and has to be replaced if it fits into the frame at the top and bottom but not in the centre.
If your door fits together at the top but has a gap at the bottom, the hinge may only need to be adjusted to bring it back into alignment.
What kind of hinges are on my uPVC door?
Finding out what kind of hinges you have on the door comes after you’ve examined the alignment of the door.
Banner hinges
This kind of hinge, which is frequently used on contemporary uPVC doors, gives you the maximum flexibility while adjusting the door. vertically, laterally, and compressively (moving the door closer and further to the door jamb).
thigh hinges
The earliest type of hinge being used today, they may be seen on older uPVC doors. Depending on the hinge’s age, it may just have lateral adjustment, lateral adjustment plus vertical adjustment, or no adjustment at all.
T-hinges
Similar to a flag hinge, this kind of hinge can often be moved both laterally and vertically.
What devices do I need to make adjustments to an uPVC door?
a screwdriver with a flat head
a screwdriver with a Philips head
Allen keys, sometimes called hex keys and typically measuring 5mm.

How to modify an uPVC door’s Butt hinges
If there are two Phillips screws on the side of the hinge, crank the bottom or top screw to achieve sideways movement. Certain butt hinges may be rotated laterally by up to 2mm.
Using an Allen key, adjust the butt hinge up and down using the adjustment on the top of the hinge. To access the adjustment, you must remove the top cover.
When you adjust the pin if there is a grub screw in the hinge’s centre (facing you), you must first release it since it holds the pin in place.
A uPVC door’s Flag hinges: how to adjust them
In order to get to the adjustment screws:
The lateral adjustment screw on a flag hinge may be concealed by the plastic cover that covers the hinge.
Loosen the two Phillips screws on the inside of the hinge to remove this.
Next, using a flat head screwdriver, remove the cap.
To reach the door height and compression screws, you might need to remove covers from the top and bottom of the hinge.
Several manufacturers could request the adjustment screws in a different method. Always verify which screw is responsible for which adjustment as you make it. A compression adjustment screw may not be included on all flag hinges.
Changing the screws:
Typically, the hinge’s top screw is used to adjust the door’s height within a 4.5mm tolerance.
The door may be laterally adjusted with a 5mm tolerance using the screw at the side.
The compression is often adjusted with a tolerance of 2mm using the screw at the bottom of the hinge.
Take an Allen key and turn it one or twice to start, then test the difference after the adjustment to see whether it worked, and so on until the proper position is obtained.
With an uPVC door, how to adjust the T-Flag hinges
The main difference between a T-Flag hinge and a flag hinge is that a T hinge could not have a compression adjustment. Use the flag hinge as described above.
How to modify uPVC doors to eliminate draughts
uPVC doors sometimes fall out of alignment as a result of screws, locks, and hinges being loose from frequent or severe use. You must adjust the door latch so that the lock fits firmly in the latch and pushes the door firmly into the frame in order to resolve the issue.
You may modify the latch or the hinges on an uPVC door to make it fit better in the frame and draught-proof it. If the frame of your uPVC door is loose,
When you pull the handle, it will jangle. By circling the edge of the door frame with your touch, you may also detect draughts.
Instead, you might need to minimise the compression of the door by widening the space between the door and the frame if your door closes in the frame but won’t latch.
Two strategies exist for doing this.
By releasing the screws holding the strike plate to the door frame and moving it towards the door’s entry, you may tighten the fit.
Alternately, you can slide forward to make the fit looser so the latch will engage the strike plate.
Try and adjust for the ideal fit by
closing the door and adjusting the screws to see whether it fits.
The compression screw can also be adjusted as previously illustrated.
How to fix an uPVC door that has fallen and is dragging on the floor
The optimum door for this modification is one that has sagged more towards the handle side than the hinge side.
Apply an Allen key to the hinge’s screw on the door side.
Beginning your adjustments with the door closed.
Check to see whether it drags after a few of clockwise spins.
Adjust the hinges so the door opens and closes smoothly.
By adjusting the screws and trying the fit while shutting the door, you may test and fine-tune to obtain a perfect fit.
The compression screw can also be adjusted as previously illustrated.
Height adjustments for uPVC doors
If the door has to be raised if it has lowered
You can change the screw that regulates the hinge’s vertical movement higher (or lower) in the frame.
Start with 1-2 complete rotations on an Allen key and make adjustments from there.
Even after adjusting the hinges, the door is still out of alignment.
There may be an issue with the hinges if you have adjusted the hinges but still can’t get the door to fit. If the door is still covered by warranty, you may either try to repair the hinges or get in touch with your original provider.
To ensure a flawless fit, we advise only replacing your hinges with those from the original provider.
It’s important to remember that a poorly fitting or aligned door will wear out faster and have a shorter lifespan.
In addition, a poorly fitting door will draught and lower your home’s energy efficiency.
examining your entrance door and any outside doors Regular visits to your home can help keep your doors in good shape, and you can make little modifications as necessary before they grow into a much bigger job. You can extend the life of your uPVC door if you know how to adjust an uPVC door.
