I'm after some advice regarding squeaky bastard flooring. I think whoever the dick was who put the upstairs flooring down used nails, and probably incorrect ones
The flooring is a good thickness at 22mm but it's really irritating. I bought some Spax 60mm decent flooring screws to try and sort it. My question is can I just drive these screws in next to the original nails or do the nails need removing? Any help appreciated.
Can I assume your flooring is original planks rather than modern chipboard T&G? If so your primary concern, certainly in an older house (10 years or more) is where are the pipes and cables? Traditionally pipes and cables were chased along chiselled out notches on the top of the trusses. Many a house holder has come to grief driving a screw through a pipe or cable. Once you’re 100% sure you know where the obstacles are you can screw or nail. If you screw you may find some nails become a little proud where these new screws really tighten the pieces together, just use a nail punch to tap them down.
