I recently had the boiler in my 1900s house replaced. The previous owner had boxed the water tank in behind a wall in the back bedroom (clever, I know!) and when it was removed we realised that we'd need to replace some floorboards, skirting board, wallpaper... and part of the ceiling!
As this is my first house, I'm far from knowledgeable about such things. After some research I've found out that the method of choice for repairing such holes seems to be cutting the hole to a regular shape, fixing a piece of wood to the ceiling joists and screwing a piece of plasterboard to the wood to cover the hole.
The hole itself is irregular - about 8-10 ins long at the widest part (it's quite long and thin) - and some of the ceiling immediately surrounding it looks like it might need to come out too, as it's a bit cracked - from where the water tank was taken out I guess. It seems like the ceiling is made from plaster board (do you know how I can tell for sure?), but it is backed by strips of wood (which have been sawn off near the edges of the hole) and what looks like some kind of mesh above that. Will this cause a problem?
I'm thinking of trying to get to the hole via the loft, so I can make sure I know where the joists and any wires etc are, before I attach the wood to them, and attach the plaster board to that. Does this sound like a feasible plan?
I just want to know that this method of repairing the hole is suitable given this situation... and what materials I would need exactly:
1) what do I use to cut the hole?
2) what is the best plaster board to use?
3) what should I use to secure the wood and plaster board?
4) how do I make good the repair?
If anyone could give me advice relating to this specific job, I'd be really grateful!? I just want to make sure I'm properly prepared!
Thanks in advance!
