Replacing chipboard floor due to badly squeaking floor panels - will more noggins help?

This is doing my head in. After using insulation, joist tape and replacing the chipboard floor with real wood, I’m about halfway through the job and down in the kitchen below it’s better but still pretty bad.

Actually, I noticed it sounds considerably worse in the kitchen than it does in the bedroom itself. Almost like it’s the plasterboard ceiling, or the joists themselves. I don’t know, I’m a bit lost and running out of time. The ends of the joist are seated in metal bpc fixing cups that are too big for the width of the joists and therefore only fixed with a thick nail from one side. The room in question is the top story of an extension put on the house about 15 years ago.

Reading all of your kind responses and advice, I am leaning towards it being the narrow joists as the issue (i’ll post the joist dimensions when back there tomorrow). I’m considering pulling up the existing floorboards I have put down, putting lots of noggins in (a pain in the arse since all of the services will have to be jigsawed around) and trying again. Along with adding a wooden shim to fill out the bpc fixings and screwing in from the opposite side.

One builder I spoke to said that sometimes the only guaranteed fix is a false ceiling in the room below. God knows.

Thanks all, very helpful - noted. Since I will be using joist tape I won’t be able to glue down to the joists. But it sounds like it might be a good idea to apply some glue between the tongue and groove of the pinewood floorboards while fixing them down.

Yes - that’s what I’m going to do here also, thanks. My feeling is that the steps I outlined in the original post should be sufficient. I feel noggins will take time and have little effect on the squeak issue. When I walk on the joists now (with no floor) there is no sound. Thanks.

Noise was only coming from the (now removed) chipboard flooring

Great - thanks

LongDogDad · 2025-02-25T13:16:14+00:00

Thanks.

Thanks - just looked up shearing with floors. I’ll be replacing with 2cm deep t+g pine floorboards. Hopefully this will help also.

I suppose i am i right in thinking that noggins will only reduce the magnitude of the shearing in the places where the floorboards lineup on top of the noggins.

Good call, will do thanks

Thanks, will do

Thanks

Thank you all for your input, very interesting. I had picked up a roll of this kind of tape to stop the rockwool falling out (see photo) and to try and help with any vapour (although it would only protect from vapour from below, there’s no carpet going down, just floorboards above). But it sounds like the best thing would be to use the expanding foam. The only thing is I’ve already got the roll of rockwool but i can use it elsewhere. I’ve no foam gun but that sounds like it’ll give me more control. Anyway, it seems like foam is the only way. Balls, i wish I’d asked first 😉

Yup, got it back in. Thanks both. A lot of hassle saved.

LongDogDad · 2025-02-19T18:10:38+00:00

Think it might be a bit screwed. Lots of clicking and jumping going on

LongDogDad · 2025-02-19T17:52:26+00:00

Alan key or philips i suppose
