Hi all and nice forum
Posted this on another DIY forum but throught i'd post here too just in case

I have a spare room in our house which creaks like hell, i thought ok lets get the boards up and have a nosey then glue back down and use screws instead of nails.
Took me best part of 4 hours to get all the bloody nails out and 2 quite nasty cuts later theyre all out

However i cannot get the two T&G chipboards to come free, video here

Can anyone suggest anything please.? Im tempted to just rip them up and tidy the edges afterwards then replace the chip boards with compressed ones ??

Thoughts please.

It may just be the chipboard moving up and down and creaking on the nails. There are special screws for fixing floorboards, they are threaded at the top and bottom but have a smooth area in between which allow you to fix the boards down tight. I would have a go with those first before doing anything drastic.

Before starting this though have a good look underneath the boards and see if there are any pipes/wires, mark the position in marker pen on the top side of the boards so you don't screw through any of them.
