Replacing a uPVC door handle is a relatively easy task (providing that you are
replacing the same sized handle as the existing one). All you require is a Philips
Screw Driver and a Junior Hacksaw.
Simply unscrew the screws on the internal handle, remove the existing handles
– then place the new handles into position and screw the handles together
with the new screws provided (sometimes new screws may need cutting to the correct
length with a Junior Hacksaw).
