Ceiling damage from upstairs leak poorly repaired. Thoughts?

[Joonyer]

Hi all,

Previous owners had a leak from the water tank above the living room. They repaired the ceiling, but poorly.

So now the paint over the joint is warped and cracked for about 6ft in length.

I'm absolutely not a skilled decorator. If I paint a wall and nothing catches fire, it's a good day.

So I'm going to get a quote to have this mended to a good enough standard for selling the house (going to market next month).

From the pics (I appreciate they're not great) could anyone give their thoughts on how this would typically be repaired? The T-junction looking bit is the worst, then the line extends away down the joint. Is it going to need skimming etc? I want to avoid having the entire ceiling redone as it's a big area.

Thoughts and any ballpark expected costs would be greatly appreciated, thank you.

Matt

For a quick fix, assuming the ceiling had previously been skimmed:

Score a straight line with a knife 1.5 inches either side of the crack, and remove this strip of plaster skim.

Refix any plasterboard edges that may have dropped by screwing into the nearby joists.

Apply scrim tape along the cracks. Very important to do this.

Patch with finishing plaster.

Best get a pro.

Thanks buddy - on reflection I'd say you're spot on. As happy as I am to try most things, plastering is one of those skills it's worth paying for!

So I'm gonna do that rather than make it worse.

Thanks for your thoughts - much appreciated.
