Many homes these days have a uPVC door and at some point during their lifetime may need a little TLC from a maintenance point of view. Sometimes, for a variety of reasons, the doors may begin to sag, droop or catch with the outer frame. This is frustrating, but there are some things that you can do to get your door working well again.
Firstly, it is worth considering why you think your uPVC door may need adjustment. It may not be operating smoothly as you would like the cause could include hinges needing adjustment, hot weather conditions, poor initial fitting, and or alignment. Let’s get into how to adjust uPVC doors.
In warm weather conditions particularly on south-facing elevations extended periods of sunshine can cause the uPVC to expand. This can make the door difficult to close without catching on to the door frame. In this instance, depending on your hinge type, you may be able to adjust the door away from the point it is catching using the hinge adjustment. Common types of hinges that will enable you to do this are flag hinges, butt hinges, or T hinges. Usually, they will have an adjustment screw that can shift the door left and right up and down. Finding the optimal position will take a bit of trial and error. Depending on the severity of the expansion adjustment of your uPVC may not be possible due to the original cause and the tolerances being insufficient to make a difference to the operation of the door.
It is very important that before commencing any adjustments you check the warranty for your door and installation. If it is still under warranty, the manufacturer might not cover self-adjusted work and may incur charges for replacement or repair works to be carried out.
There are three main types of hinges that are commonly used on uPVC doors
One of the older styles of hinges. The butt hinge may have no adjustment but may have some lateral movement possible. This being the case if you need to adjust vertically i.e. lift or drop the door then you may need to reinstall your door to overcome this problem.
It is one of the more popular modern hinge types due to its flexibility. 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.
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.
Before starting any adjustments, ensure that your uPVC door is still covered by warranty with the manufacturer that supplied it. Firstly they may well take care of this issue for you under the terms of the warranty. Secondly, they may charge for coming out to rectify any problems or replace parts that may be a result of you trying to adjust the door yourself.
After figuring out how to adjust uPVC doors, and putting these actions into place, sometimes it’s still not enough. The nature of adjusting doors well can take several attempts to get right. New hinges may be needed if you find you are unable to get the door properly aligned. Replacement hinges are relatively easy to replace and not an expensive remedy to the problem. You can find new hinges from specialist outlets online or on the high street. It is worth comparing prices to see where you can get the best value in terms of performance and price.
If you do intend to replace the hinges it will be much easier if the door sash is left hanging on the frame as you replace each one in turn. Using this method will ensure that the hinges will align well.
It is also worth checking the diameter of the screw is a suitable size for the holes on the hinge itself. If not your door sash may drop which in time will likely require further adjustment or replacement of the hinges.
