I need to run a larger gas pipe through a BISF home that has had the exterior walls bricked. Are there any special precautions to take, regarding maintaining the integrity of any expected membranes etc.
There is a steel joist at the back of the airing cupboard/wardrobe. Are there any steel joists running parallel to the front aspect, between this joist and the front wall. I need to run the pipe from the front wall to the wardrobe.
Any comments or suggestions will be gratefully received.
