How can you fix a uPVC door with a broken mechanism?
Use a screwdriver to loosen the screws on the door handle. If this is too tight, it can pinch the spring and prevent the mechanism from working. By loosening this, you may be able to open the door. Additionally, you should adjust the door hinges in case your uPVC door has dropped in changing weather conditions or simply over time. Once the door is back in position, you should be able to open it.
