We live in Massachusetts and have a brick ranch built in the 50's with radiant heat in the ceilings. One of our ceilings is all cracked and in need of repair. We assume the cracking is from the heat, but we're not sure. This is the second ceiling that has had this damage. The first one was in our bedroom and when we fixed the ceiling, we changed to electric heat in that one room. We have had several contractors, plumbers and plasterers in to look at the damage and am not sure what to do. It seems as though not too many people have the knowledge necessary to do the job. What type of ceiling can be used to replace the old one? Has anyone else had this problem of serious cracks in the ceiling? Is it time to ditch it all and get a new heating system? Who do we go to in our area to help us with this issue?
