Screw Fixing Advice...

    Hi All,

    Now that I've got your attention ... ;)

    The first floor in the timber-frame house is 18mm OSB on top of 10" joists. Since the house has started to dry out there is a considerable amount of creaking as I walk around the upstairs.

    The OSB was provided and fitted by the TF company when the frame was being put up, and was nailed down.

    I heard that screwing this down is the only way to go - is it?

    Can anyone recommend the type of screws that should be used - coarse/fine thread, any other details?

    Any other tips - should I only screw where I hear creaks now, or should I go mad and cover the entire first floor? What kind of spacing between screws?

    Thanks for any help!

    Tails_naf,
    Not being smart but it is a timber frame house. No matter what you do it's going to "creak". Its naturally drying out, the frame etc. This will happen for some time so imho, you'll just have to live with it. Have lived in estate one before and have just build TF extension to my own house and it's what I hear the whole time.

    So you are saying it will creak for some time, but there is nothing I can or need to do, and it will simply stop over time?

    If it will go away on its own, then great - but I just want to check to see if there is something I should do to help it out...

    I have a timber house and there is no creaks from the upstairs at all.
    The floor is double T+G chipboard, glued and screwed directly to the joists.

    If you can rectify the problem areas now before you lay finish flooring then you would be well advised to fix them.
    If necessary remove and refix OSB panels that butt up against each other and leave a space and glue and screw.
    My mate has some squeaky OSB floor panels that drive him mad.

    nails arent great at all in floors because when the joists shirk the nail pulls out of it slightly leaving a gap between the osb and the joist (1-2mm)it is this gap that causes the squeak as everytime you step on the floor your weight pushes down and closes the gap. when the gap is closing you get a squeaking noise of the osb rubbing against the nail. glue wont solve this. glue SHOULD be used anytime i lay these floors its glue and screw all the way. what you need to do now is get 50mm coarse thread screws and screw the floor every 9". you have a timberframe house your going to have loads of squeaks it cant be avoided, some can be fixed others cant.
