Adjust uPVC Doors

If you are having problems with uPVC expansion and you are struggling to close your door, there are a few options that you can do to help. In extreme circumstances, uPVC expanding can prevent doors and windows from closing. However, if you are in a rush to revert this uPVC expansion, pouring cold water over the door or patting it down with a wet cloth, can speed up the process.

Another option is adjusting the hinges. However, we would not recommend this option. Because when the uPVC expansion shrinks it can cause problems with the opening and closing of the door or window.

Should I Choose A different Door?

PVC doors are an excellent choice when it comes to home improvements. Many benefits can exceed the occasional uPVC enlargement. However, if uPVC expansion is a common occurrence, then it may be a better choice with composite, timber or even Aluminium. The choice is up to you, and PVCu can be one of the most suitable options for many people. However, if uPVC expansion is a significant inconvenience, you may be better suited to a different material.
