Gap behind coving leads to brick and is a mess
Hi all, first-time homeowner, and I'm getting some plastering done at the end of the month. I'm removing the 1960s coving to give a clean finish to the walls.
When removing the coving, I've found so many problems with the space behind it. Loose bits of plaster, chunks of old brick and plaster coming off with the double 2-inch nails, and the worst was the room I just did today. It looks like it leads to the wall to the neighbours (semi-detached) and is a direct gap to the attic (i can see and touch insulation). It's brick, and it looks like there's some wood placed between the brickwork which is attached to the wood that was attached to the coving that I broke when pulling the coving off. I put an image in which shows how the wood usually sits behind the coving between the plasterboard and ceiling (pic 3 - on the right is the wood that remained).
A few questions
- Is this OK to leave for the plasterer? They assured me that behind the coving it will be a mess, but this is an inch+ deep and a 2-3 inches tall of filling to do where the small piece of wood was that got pulled out
- Should I re-fill with wood (the same way it was before, that the coving was attached to)
- If so, how do I do this? I'm guessing I can just nail it into the bits of wood there - but is there anything I should know/check to see why this wood broke and the other didn't?
- Is it OK that this was broken? Is this wood important, or have I fucked up and will I need to get a builder in to check this? Dumb question I'm sure, as I don't think coving is structurally important, but I don't want any problems going forward as this house has been problem after problem
- Is it OK to breathe any the space after cleaning? This is my office, and I've not covered it, but will there be any problems for the few weeks ahead of the plastering job to sit here 10+ hours a day?
Any help would be appreciated. I wasn't sure what to flair, so I did building as this seemed beyond a bit of polyfill
Finally, there was what seemed like old soot behind much of this. There is an old covered chimney on the left between two rooms. I'm unsure if this is soot, black mould (ancient) or we did have a boreworm infestation that we got treated (it was not due to damp I was told by the specialist, and the attic has remained damp free so far in the 6 months i've been here). Google suggests this could be boreworm droppings. It's chalky and leaves a black smear like charcoal would. If it is mould, is it likely to be just really old?
