Our 1920s california bungalow has a lot of squeaky floorboards throughout the house and it's driving me nuts. Our 2-year old is especially sensitive to noise, so I have become quite the practised ninja darting around the house to avoid the dreaded creaks and squeaks, but they seem to be multiplying.
After a particularly bad squeak last night I started googling something that can be done without lifting the carpets and came upon this - http://www.nzsqueakyfloors.co.nz/ It's a kit that includes special screws and a tool that lets you drive screws down into the joists, and the head then snaps off below the carpet level. I found a video on Youtube here which demonstrates it (American, but it looks like the same tool) https://www.youtube.com/watch?v=4gUW-IhSMBc
What I want to know is, is this a good approach? Has anyone used it and can vouch for its value? As someone who isn't particularly handy, it looks reasonably simple to use (once you've located the joists in each room), but is there a better approach?
