Hi, our front door pushes into our hallway and it practically drags off our wooden floor, a few scratches there already from stones getting caught. No mat will fit under it and I fear the only option is to get someone to do a sunken mat for us or perhaps get the door shaved at the bottom. I want to get a runner carpet along the hallway also as it is too noisy and just ruining my floor at the moment keeping it all exposed. So basically, can I get the bottom of the door shaved to accommodate a mat and a carpet runner or will I get a mat sunken into the wooden floor and just have a big rug instead. Would it be expensive to get a mat sunk into floor and if so, roughly how much and who on earth would I ask to do it if I were to go down this route?
