I live in a new build house, les than 3 years old. The flooring on the first floor is particle boards that are covered with carpet. 2 of the rooms have creaking floor boards. I lifted the carpet, removed the screws and put new screws in that were larger (4.6 x 64 mm). The floor boards are tongue and groove chipboard approx 2.4 x 600mm. They are laid on 9 x 3 inch hardwood floor joists. The room is approx. 5 x 5 mt. The boards are NOT glued down. I am not sure what the cause of the noise is.? Its been suggested : a) they could be too tightly fitted b) the boards are not thick enough c) where the tongue and groove are butted together they should join over a joist BUT in my case they do NOT - so there is a weak point causing flex and therefore noise. Any suggestions?
I am not sure what the cause of the noise is.? Its been suggested : a) they could be too tightly fitted possible but I doubt it, you would have remove the skirting to check b) the boards are not thick enough they come in 18mm and 22mm both which should be ok c) where the tongue and groove are butted together they should join over a joist BUT in my case they do NOT - so there is a weak point causing flex and therefore noise. This is how it is fitted, so there is no waste the strength is in the tongue and groove as long as the joints ate staggered. Any suggestions? Firstly your joists won't be hardwood and I doubt they're 9x3, more likely 9x2 in a new build. The cause of the cause of the creaking is usually due to the joists shrinking after first fitting, the creaking is the flooring or plasterboard rubbing on the nails. If you have already screwed down the flooring then I would suggest that it is the plasterboard underneath that is causing the creaking, do you have any nail pops in the ceiling below? If so knock the nails in so it tightens the plasterboard back up against the joist then fill and paint. This will probably cure the creaking.
Nails! Do peeps still use these nails for plasterboard, been years since I've used them. Just had to screwed the living, dinning & kitchen ceilings here, due the nails pulling through the boards in places.
New houses are thrown up in weeks by site trades who have no care or comebacks when small things go wrong, as chippie said it's just the floor boards rubbing each other as there is no glue on the joints.
Try spraying the noisy joints with furniture polish, give them a good spray so as it gets right into the joints, works wonders.
KIAB it's been years since I've used nails on ceilings myself but I have seen it done a few times recently, unfortunately.
thanks, the plasterboard is screwed in. the joists are older re-cycled from the old house that was here. there are 2 walls from the original house the rest is new.
