Hello, A plumber had to cut some tiles out to fit a part of the new boiler, tiles came away in a full block with some of the wall atrached too, how do I stick it back on as the cold air is coming through small gaps where the boiler part goes outside! Thanks just need to know what would stick as its heavy.
Tiles shouldn't be stopping air coming from outside. You may want to post a picture or two so people can offer advice on this gap also. Possibly where the flue is and may need cementing in also.
Thanks, its tiny holes letting the air in around the joint, would that expanding foam sort that bit? Should be a picture on now too.
