False ceiling - bad work?

[mrgazer]

Hi,

I have had a builder came in to do a false ceiling for me, he used wood studs to support the plasterboard. He has got to the stage where it is all plastered.

I got myself a ladder and pushed the ceiling and find that they have some flex to it, ie. not hard firm. You can almost see it bend when pressed.

Is this normal for wood stud built false ceiling?

Or has he done a very bad job on it?

Thanks

Well, what size are the timber studs?

I assume you mean the plasterboard flexes when you push on it. This is normal.

The plasterboard should be 12.5 mm thick if the ceiling studs were at 400 centres or 15 mm if they were at 600. 12.5mm at 600 will flex more but so long as the board edges are nogged or at least fastened to their neighbour with a bit of backing ply/osb then you wont have any problems with cracking. After 40 years it might all look like it's sagged a bit if you climb up there and throw an eye along the ceiling but it probably won't be the most considerable of your worries!

How have they supported the timber to create the ceiling?
