The gyprock ceilings in my old house have pulled away from the ceiling batons as a result of the glue failing. I have since got two quotes to re-screw the gyprock to the batons, reset the joins and patch over the screw holes.
The quotes vary markedly in price. The more expensive quote (double the cost) involves propping the ceilings prior to re-screwing and sanding back the entire ceiling (not just the patches), which they believe is the only way of making the ceiling look brand new.
I would be grateful to hear from other Rioters on their experiences repairing sagged ceilings and techniques used, and perhaps recommend a plasterer so that I can get a third quote.
Thanks very much.
