My home's door has been replaced with a heavier fire door, however it's super stiff now and requires a lot of strength to open. I think the door itself is quite heavy, but I also think that the 'stiffness' it's given by the hinges. We also have an auto-mechanism but that doesn't seem to be affecting this.
Is there a way I can regulate the hinges and make this door less difficult to open? I'm not an expert whatsover so please explain in an easy way :)
