To ensure that you always get the best use out of your patio doors, follow this blog post on how to adjust patio doors.

    Tools needed

    • Allen keys
    • Philips cross-head screwdriver
    • Flat-headed screwdriver


    When it comes to something such as adjusting patio doors, you need to make sure that you are ready and prepared. Ensure that you have a clean working space and you are fully aware of all the steps that you are about to take. Make sure that your tools are within reach and you are ready to go!


    Finding out which hinge your patio door uses will be vital to your adjustment process. This will be the first proper step to adjusting your patio door. The likely hinges on the door will be:

    Flag hinges : One of the more popular modern hinge types due to the flexibility it offers. The flag hinge will usually be adjustable in 3 dimensions, lateral, height and compression. Lateral will move the door left and right, height; up and down and compression; how tightly the door is pulled towards the door frame.

    T hinges: Very similar to flag hinges with the exception that they do not offer any compression adjustment. The T hinge will only allow for lateral or height adjustment.

    The adjustment

    Of course, each type of adjustment will be different, and it will be dependent on the part of the door that is out of place. The initial steps to take will be to figure out where the problem is coming from, on the door. Before you make any changes, you should make sure that your door is still within it’s warranty and that you are not going to lose out if you do not manage to fix your door. Some of the following bullet points are examples of where an issue could be and how you may go about fixing it.

    • If it knocks directly at the frame on the side, you have to make a parallel adjustment to your patio door. To adjust the distance between the frame and the sides and adjust diagonally, you have to turn the screw in the corner as well as the stay bearing.
    • When patio doors grind against the upper or lower section of the frame, you have to level the heights parallel. In order to adjust the height of a patio or balcony door, you have to use the corner bearing.
    • To regulate how tight your door is, you have to adjust the contact pressure. If your door has a bad draught or it is difficult to open and close, you may need to adjust the contact pressure. Locate the mushroom or locking cams. They can usually be found at the side of the handle. Pull out the locking cam and turn it clockwise to increase the contact pressure or do the opposite to lower the pressure.
    • When the leaf grinds against the frame or hangs incorrectly, you may need to readjust the entire door diagonally. The distance between the leaf and frame should be the same on both sides after the adjustment. Turn the adjustment screw with an Allen key to perform this adjustment.

    After following these steps – you should have a perfectly fixed patio door. If you are still having problems with your patio doors then you can contact Genesis Collection and we can help you further. Remember to always be careful and safe when you are attempting adjustments such as this.
