Hello everyone,
after some advice if possible.
Had some external wooden patio doors put in by a builder a couple of years ago, the doors are sat on top of a concrete door step which sits on top of both leaves of cavity wall, is this correct method of installation, only the tiles I used to cover interior side of doorstep, which is higher than the internal suspended timber floor have blown off.
Thaks in advance
