Hi - Had some new carpet installed on my stairs last week and am not comfortable with the fitting. The bottom step is a bull nose but appears to have been fitted over the top of it and stapled to fit in the corner which looks a little shoddy. Also, it's quite loose. I have the fitter coming back today but want to know if i have grounds for a complaint or is it standard? The previous carpet wasn't fitted this way. Attached pictures so any opinion would be greatly appreciated. thanks in advance!
