Got it done earlier in January, happy with the result, feels solid. For future, I'd plan out sheets better to get a row of noggins in line down all joints.

The extractor in the en suite does work it's just not that good and it's in the opposite end of the room to the shower. It's rated for 68m3/hr whereas theres plenty of inline fans which claim several times that number. Installing one per room isn't a problem, maybe units which have a trickle and boost would be ideal.

I have an en suite which currently has a through wall extractor which does a poor job of extracting steam from the shower. The main bathroom has no extractor as it appears the previous owners removed it and tiled over the hole. Both bathrooms have their own isolator switch above the door. It looks like two (maybe one with joined ducting?) inline fans would be the best, not sure what venting option is best, the gable wall is right next to the bathrooms. Do I take this as a good time to improve ventilation throughout the house, a more complete system pushing fresh air into the upstairs hallway? The house doesn't suffer from mould or condensation, trickle vents on a few windows throughout so thinking more about air quality.

Thanks both, been searching for the appropriate screws and somehow never came across those!

I'm replacing floorboards upstairs due to excessive movement/noise, background in: Adding noggins between the joists is simple enough and is having the desired effect but I'm unsure how best to approach the joists in the hangers. It would appear that the hangers aren't the proper size for the timber which is 44x220, have had a suggestion of pulling the nails out, packing with shims and securing with screws. My research though seems to state that only the fixings supplied with the hangers can be used. I'll be adding a row of noggins by these hangers but I'd still like to tighten these hangers up if possible.

Thanks, I was planning on putting screws into the three unfixed hangers, for the others that don't look as tight, would it be wise to try and hit the nails in further or add screws or best to leave alone? I think I'm going to noggin the long edge joins on the boards which may seem overkill but I'd like to put this issue to bed.

I'm planning on using spax floor screws, I also have 5 egger p5 boards and their glue sat waiting. What I'm stuck on is how can I give myself the best chance of preventing the same issue that the main bedroom experienced where the creaks just returned. I've had suggestions of installing more noggins or heringbone struts to form a more stiff base for the floor. I'd also be happy to abandon the p5 and lay sheets of ply if it would help achieve a more solid floor.

Hello, I bought my first house two years ago which was built in 2005. The biggest issue I've faced since moving in is that the vast majority of the upstairs floor creaks to such a degree that it bothers me daily. My initial research led me to think that it be a case of fastening the boards down or replacing nails with screws but sadly it's turned out more complex. In pulling up the floor in two rooms so far, have found that the joists are 220x44 spaced at 400, floorboards are 18mm chipboard t&g which was screwed down. In May I had the main bedroom floor lifted and replacd with 22mm t&g chipboard which was glued and screwed, six months later and the room is now pretty much back to where it was before. In the meantime before the main bedroom deteriorated, I lifted the floor in bedroom 3 myself with the intention of fitting new 22mm t&g, this floor is still up as I'm hesitant to put down the boards I've bought and end up in the same situation. The opinion of trades I've had look at this room is that there is probably some movement in the joists, but don't have any firm suggestions. In the room which is up, I've found a few things that I need to fix but I'm unsure if they're a cause or red-herring: Joists not nailed in hangers, can be seen in photos, though this is only the 3 short joists which only span that room where they meet the timber going across the end of the stairs Noggin noise coming from the nails, almost the whole floor creaks so I don't believe this to be the root issue Holes for cabling/pipes not done within regs I'm stuck with how to proceed, ideally I'd like to have someone come and report how to resolve it, specifying materials, fixings etc which I can follow. A structural engineer I spoke to said they would be unlikely to be of much help. My only idea was to firm it up with additional noggins and maybe fit ply.
