Hi everyone Recently moved onto our first home and have noticed a very unusual metalic noise when walking over certain parts of the floor (almost sounds like a rusty hinge opening or a see saw). I will try to include a video of the noise. People have said it may be the loose nails/loose boards but I've seen a few videos online and nothing is like this. Worried it may be the boards pressing on the pipes underneath and this could be dangerous? House is around 45 years old and I believe its chipboard floor. Thanks Kevin
