    Evening all, my floor upstairs squeak so bad, after investigation I found out it's not the 18mm wooden floorboards but the nails in the noggins that are squeaking like f.%$.
    My plan is to remove floorboards where its squeaking and put in screws to strengthen up the joists and maybe a section of new noggins depending on results.
    Is there special type screws for this, like stronger than normal and a certain length, also do I need to pre drill.
    Cheers.

    Most screws now are stronger than you need. Try cutting through a few with a hacksaw to see how hard modern steel screws really are.

    You don't need to predrill but if you do you may increase the accuracy of placing the screws. What I normally do and have seen others do is drive 5x 120mm screws at an angle straight though the side of the noggin. If you have access to the far side of the noggin the same screws will do the job.

    Wake me up when it's all over.

    With shrinkage, the noggins will have all be a tad shorter than needed to stop movement.

    If you are screwing them tight to the joists, you will get away with a few, until the pull is too much, something will give...
    Best thing is maybe two together and add a shim or wedge on every third one..

    Modern design screws are so much better. Before power tools arrived, (flathead) screws were designed to go in easily with a manual screwdriver, with the result that they come out easily too.

    What would give ?

    If 10 noggins have shrunk by 1mm each, thats a pull of 10mm on the last joist.

    Thats plenty enough to pull the nails out, and crack a plasterboard ceiling fixed underneath.
    Could easily be 3mm for each of 20 joists too. Thats in the ballpark of popping the ceiling down.
