I've been in my current property for a year and a half (social housing) and me and my mum are convinced the house is sinking on one side. For clarification I live on what is known in my local area as the "pit top" the reason it's called this is because just past my back garden is where all the old mines are and I know there are tunnels underneath that you could walk through to get from pit site to pit site. Anyway I've noticed things around the house like cracks along skirting boards, door frames and my back door sticks when trying to open it. I also have a piece of skirting board missing and all you can see is brickwork behind the plaster a very deep hole and the original floor doesn't even meet the wall I can put my hand underneath it.
All the above issues are in one room and this room also has sloping floors mainly in the corners (which is now making my laminate start to bow in the middle of the floor) . I've had a look outside and all the left hand side of my house sits lower than the other side. I have an inspector coming out in a couple of weeks but I'm scared I'm going to be fobbed off as subsidence isn't something they specialise in but they are the only people the council are willing to send out to have a look.
I've added pictures so you can see what I mean x
