I had a carpet fitted two weeks ago but I am not happy with the fitting. I don't think the carpet is tight enough on the grippers. In a few places the carpet looks fine and completely flat but mostly the carpet bulges up a few inches from the gripper and in a few places I can lift the carpet off the gripper with my fingers. I called the fitter back but he was quite hostile and said it was ok. I then called in the guy from CarpetRight and he also said the carpet was fitted correctly. So my question is - just how tight should a carpet be and how do I judge this? Any advice please.
