A company are looking to refit a set of bi-fold doors for me.
I need the internal level to an additional 25mm higher than they currently are.
They have said that they will use a - knock on/frame extension/add-on in order to increase the height by 25mm.
Is this something that is standard and should be done?
Thanks
