Browse Forums Building A New House 1 Jun 24, 2022 2:03 pm Hi all. I have posted last year about my new double storey build where the entire flooring upstairs (apart from bathroom) has developed loud squeaks that can be heard loudly from below. I have taken out one of the downlight enclosures from the downstairs ceiling, and I've taken some photos. It appears that the nails that have been used to fix the subfloor (particleboard) to the floor joists have penetrated all the way through, and popped out the end - see attached photos below. Is this considered proper installation? Could this be the reason these loud squeaks have developed?

Do you know if you had glue as well?

Do you know if you had glue as well? Thanks for the reply. Yes, I've been told by the builder that glue was applied. But upstairs I can feel some very minor movement under my feet in certain areas (which are also the worst creaking areas), so it's possible the glue didn't hold very well.

Using nails instead of screws ( the squeak is the floor moving up and down on the nail) 2. Not enough glue ( you have to use a huge amount) It is fixable by going back and screwing the boards down.

Cheers Simeon Thanks for the reply. This is helpful. But does the nails going all the way through constitute improper installation? Or is this fine in practice?

Nails being used at all is incorrect/improper installation If the were screws going all the way through I think that would be okay Architectural Homes & Duplexes - specialising in custom designing homes to your budget Get a Free Onsite Consultation Today or send a PM for information, questions or advice. 3 2999 Thanks for all replies.
