How to Adjust uPVC Door Hinges
Tools You Will Need
- Allen wrenches (hex keys)
- Flat head screwdriver
- Philips head screwdriver
This hinge has three different adjustments.
- Height: The height adjuster on flag hinges is on the bottom and may or may not be covered by a plastic plug. You’ll need an Allen wrench for this. The typical size is 5 mm, although this can vary depending on the manufacturer.
- Lateral: The lateral adjuster can be hidden behind a plastic cover (the “flag”) or behind a small plug on the side farthest from the door frame. The plastic cover is usually held on by one or two Philips screws on the inside of the hinge—visible when you open the door. Remove the screws carefully to release the cover, and look for the Allen bolt on the side. Turning it clockwise will move the door towards the hinge, while turning it counterclockwise will move it away from the door hinge.
- Compression: The compression adjuster is located at the top of the hinge under a plastic plug. Carefully pop the plug out using a flat head screwdriver to reveal the Allen bolt underneath. Tightening this bolt brings the door closer to the door frame, creating a tighter seal.
If your door is too low or too high (consistently along the width of the door), then you probably only need to adjust the height.
If the handle side of your door is too close or too far away from the door frame (consistently along the length of the door), then you probably only need to adjust laterally.
If your door doesn’t close all the way, or you notice a draft even though the height and sides are adjusted properly, then you probably need to adjust the compression.
If your door has dropped and is tilted downward (i.e. the door isn’t level, and the gaps around the door are consistent all the way around), then you need to use all three adjusters. This is common as time goes—helped on by gravity, heat, and humidity. Usually, the door can be squared up again by adjusting the top hinge towards the frame and the bottom hinge away from the frame. The compression is also usually tightened to restore the seal lost through wear.
This hinge only has two types of adjustments.
- Compression: Adjusters on the top and bottom will move the door closer to or away from the door jamb, tightening or loosening the seal.
- Lateral: Like the flag hinge, the lateral adjuster is hidden behind a plastic cover that can be removed in a similar manner.
Some butt hinges are non-adjustable, but there are some that can be adjusted laterally. If you look on the side, you will see a Philips head screw. But before you try to turn this screw, check to see if there is a small grub screw as this locks the hinge in place so the door won’t move. Not all butt hinges have a grub screw, but the door won’t move unless you loosen it.
I Adjusted the Hinges, but My Door Is Still Not Aligned
Note that it may take a few tries to properly adjust all the hinges. If you still cant get your door squared up after a few attempts, you may just need new hinges. Hinges are usually inexpensive and aren’t hard to replace. Most companies will do the replacement for you at a low cost. You should ring at least two companies to compare service prices.
If you’re going to replace the hinges yourself, you will find it’s a lot easier if you leave the door sash on the frame and replace one hinge at the time. This way, your hinges will all line up.
Also make sure the diameter of the screw is the appropriate size for the holes on the hinge. Otherwise, over time, your door sash will sag down, forcing you to adjust or replace them again in the future.
