Repair or Replace Cove Feature?

[HardTarget]

I am about to Dot and Dab the walls in my house and I'm hoping to save the ceiling coving, but a builder mate has told me to remove them and dot up tight to the ceiling and then have the plasterer replace them at a later stage.

I was hoping I could butt the boards upto the remaining cove and then have them skimmed in when the walls are done or is this a non starter?

Also I wish to use insulated boards something like (25MM CELOTEX + 12.5MM PLASTERBOARD = 37.5MM PLASTERBOARD LAMINATES) for all the external walls, would the celotex ones I have mentioned be the right type? Not sure which type as there are so many different versions?

Why have you removed the wall plaster? What are the issues?

Removing the coving could present difficulties in removing it and replacing it.

The plaster was in a right state and to be honest I really did not want to remove it, but had a two plasterers come and have a look at skimming it and both said no chance, it would all have to come off back to brick.

I noticed when looking from above through the upstairs floor that the coving had plaster boards set at 45degree angle all along the ceiling edges. Is this what you mean about it being difficult to replace? The only problem I see if I leave it, is when I butt the new plaster boards to the old cove that they will be proud of the old coving. Not sure if a plasterer could skim this in without major hassle, hence would it be better to remove or would I be opening a can of worms?

Not even sure how difficult or how costly the coving would be to replace?

You could use a transition piece, similar to a picture rail or chair rail, to cover the transition and take up the difference.
However, this gives a further difficulty of getting a level "line" of transition all around the room - does the cove seem equal all around? The same difficulty might apply to your boards.
Where you've hacked off appears to show the cove sections unequal?

An experienced joiner could make it work. Or a learning curve DIY'er.

How the cove has been built up is, as you have seen, full of possibilities for a can of worms.
Working to what you've got would be far cheaper than attempting to remove it, and possibly cocking it up, and then having to trust a new installation by a plasterer who claims that they know how to do this kind of work.

FWIW: i wonder if the cove plaster is a lime putty mix? Or is it a brilliant white painted gypsum skim?

I have no idea on costs.

From what I can see it is all original work dating from the 1937, so I could not tell you what it is.
