I've recently moved and the garage to my new home has one wall that has separated/is separating from another wall. I've no idea how long it has been like this and I've had a couple of quotes, 1 to rebuild the brick wall and 1 to repair using Helifix. However neither builders actually were able to tell me what had caused the issue and I'm not happy to spend a lot of money repairing if there is still movement and one of the walls is still moving. I've heard about glass telltales that can be use to see if there is still movement but have mo idea who would fit these. Any help please?
