Hi Everyone, Hope you can help please with a huge problem I have. We own a family commercial cleaning business and one of our clients (a working men's club) had a new carpet laid around Christmas last year. Within a month or so three lines appeared which run right up to the join in the carpet. I've attached a photograph to show this. The club management said that this was damage caused by a trolley with rubber wheels. I reported this to my insurers who sent in a loss adjuster who said it was nothing to do with the trolley and refused to pay. The adjuster said it could have been a roll end or the marks were made by how the carpet was taped. I have absolutely no idea having never seen marks like these before. Can anyone please shed some light on what or how the marks were made please?
