Soundproofing a ceiling

[stuart23]

Got a job to price where customer wants kitchen ceiling soundproofed as she can hear conversations from flat above. Ceiling is tongue and groove onto a wooden frame and there is a gap of around 200mm until the floorboards of the flat above (old house which was converted years ago).
Whats the best way of soundproofing it?
Was thinking of taking whole ceiling down and replacing with gypframe, sound insolation then double sheeting with soundbloc plasterboard.
Any better ways of doing it?

Yeah use the heavier rockwool baffles(120) fire line slab then the gypframe and a soundbloc board and as long as the kitchen ceiling is the only problem and sound isn't resonating through somewhere else ie walls, partitions etc.
We would normally write a disclaimer with a quote explaining this

as above, or turn radio up

18 mil plank board caulk all perimeter with acoustic sealant then sounblock board caulk again .maybe not the exact process but will definitely din the noise.

Would celetex be better for blocking sound? Will cost a lot more I guess.

Make sure you put a disclaimer in your quote about flanking noise. You might be unlucky and 20% of sound coming through ceiling, 80% from somewhere else. Only way to make sure is to do the whole room!

Insulate with acoustic, one layer fire board, drop ceiling 100mm, acoustic insulation and two layer of soundboard,

id just walk mate whatever you do wont be good enough for them. Who lives in a flat and doesn't expect noise from neighbours maybe im just cynical.

Walkngs not the answer. Like a adcar says do the work but have a disclaimer in place.

By the (sound) of it your pricing for a problem make sure you put enough dough in for it ..... sorry about the pun:RpS_thumbsup:

All these suggestions sound great but what would worry me about just about all of them is the weight you'd be hanging on what are clearly narrow joists.
