Hi - my front door has been cut down in size to fit a smaller than usual opening but I noticed that the old original frame is behind the new. Today I decided I had to know why there was so much plasterboard and packing around the door frame both inside the house and in the front porch, and removed a section. I can now see that the original opening would have been larger and taller BUT, not only has this revealed lots of soft wood and plasterboard hiding the original height of the opening but there are two wooden lintels with nothing but fresh air beneath! These lintels appear rotten to me and have small holes in them - they are softish. The lintels run across the top of the door opening and are resting on the brickwrk either side - above them therefore is the second storey of the house I guess. What should I do? I can some jobs so long as they dont involved muscles! thanks.
