A couple I am friendly with had a garage conversion into a playroom. The doorway that originally opened into their utility room was sealed and a new doorway put in the hallway so the room feels more like part of the house without the need to access it through the utility room.
Anyway, that's the background, here's the problem. The old door way was sealed up with a 2x4 frame, insulated, plaster boarded and skimmed. Now on one side of the wall and only on the right hand side of where the old door used to be there are cracks forming in the plaster and a ridge appearing as if the two piece of plaster are coming together and creating a "mountain range" at the joint.
But what's puzzling is three attempts have been made to get it right, the initial work by the builder who did the job, him returning to try to rectify it and a third time when a independent decorator came to look at it at the request of the builder. Two things in particular strike me as odd:
1) The problem happens slowly over a periods of weeks with the ridge getting to its worse after about a month, so any filler, etc in the joint should be rock solid and dry by then, what's being squeezed to make the ridge?
2) It's only happening on one side of the doorway patch.
Any suggestions? I'm thinking maybe sanding back to plaster and trying to stabilise with PVA or possibly filling it with a 2 part car bodywork type filler, thoughts?
Any help greatly appreciated.
Bob.
