Hi, I’m hoping someone can advise me. I got karndean fitted upstairs about 5 years ago. To start with it was great, however now 5 years on and every single step is extremely loud, upstairs, when walked on. It’s not just a little floorboard squeak, it’s enough to wake anyone upstairs up if someone walks on it. We need to do something. Obviously I want to cry at the thought of ripping it up but we can’t go on like this as it seems to be getting worse. Is it badly fitted kardnean? Or bad floor boards (they aren’t great in rest of the house and there is zero sounds proofing between floors).
