How to Adjust a UPVC Door: All You Need to Know

There’s nothing more annoying than having your sturdy front door sticking, misaligning, or simply not opening up no matter what you do. After all, what are they there for? UPVC doors are common in the UK. They are popular because they provide extra security, insulation, and durability for a relatively cheaper price than other types. So, your UPVC door was a good choice no doubt, but it’s normally prone to wear and tear signs after a while.

Lucky for you, adjusting those issues is an easy and simple task. You don’t necessarily need the help of professionals to adjust it. We will break down everything you need to know on how to adjust your UPVC front door for a smooth movement. Read on below.

What Are the Most Common Issues Requiring UPVC Door Adjustment?

First of all, you need to pay attention to some signs that mean your door requires a few adjustments. If your door started having these issues, it’s a clear indication that it needs a little work. Check the following list:

  • Door is not closing or opening as it should. This is the most obvious problem to your upvc door. Any level of difficulty arising when you try to open or close the door means your upvc door requires hinge adjustment.
  • Door appears to be misaligned. Any visible signs that the frame doesn’t align properly with the door means it needs to be adjusted for the door to close.
  • There are gaps that allow drafts to enter. This issue means your closed door allows air to pass through because it is not sealed properly against the weather. It is important to know how to adjust your upvc door to stop such draughts.
  • Door jams or sticks suddenly as you open or close it. A very annoying issue is having the door stop while being opened and closed, which definitely means it requires adjustment of its locking mechanism or alignment.

What Are the Tools You Need to Adjust Your UPVC Door?

Now that you’ve identified the issue and decided it requires your attention, make sure you have the tools for the job. You don’t need much to get the job done. They are probably already available in your tool box at home. You will need a screwdriver, Allen/Hex key, level, chisel, and silicone lubricant.

What Are the Steps to Adjust Your UPVC Door?

Here are a few easy steps to adjust all issues with your UPVC door in no time:


It’s best to begin by figuring out if the hinges on your UPVC door need adjusting. There are three types of hinges for UPVC doors. Flag hinges are mostly available on modern doors; you can find them on the side of the door, while Butt hinges are the oldest type of hinges which are fitted on the edge of the door. Finally, T-hinges are shaped like a T; they consist of two main parts, a rectangular knuckle-shaped part attached to the frame and a tapered strap attached to the door itself.

First, you can use a spirit level to identify which hinge is causing misalignment, then loosen its screws. Shift the door to correct the alignment and then tighten the screws once more. When you feel it’s corrected, make sure the screws on the other hinge are tightly screwed as well. Moreover, if you’re wondering how to adjust the UPVC door when it has dropped or dragged a little, use the Allen key on the screws by the side of the door from the hinge until it’s corrected.

Locking Mechanism

If you feel any stiffness or resistance in the locking mechanism of the door, use the lubricant to the moving parts of the lock. Make sure it reaches the lock’s entire components and test it out by locking and unlocking the door continuously.

Strike Plate

Examine the door’s strike plate to make sure it aligns with the latch. If it needs adjusting, use a chisel to widen the hole of the plate and align them again.

Weather Seals

Check the weather seals of the door around the edges for any sign of damage. Replace them if needed to make sure that the door doesn’t allow any air to enter through gaps.


Keep opening and closing the door to make sure its movement is as smooth as possible. If you can still feel any misalignment or resistance, address the previous issues again.
