The customer had said that there was a leak from the bolts that he had put in. As he was a new customer and I didnt want the leak to cause damage to the works that I had done I offered to reseal the bolt to prevent more water getting in.
He never took me up on the offer and in fact went on to attempt a repair that wasnt required. This was over 1 year ago. he is now attempting to obtain costs.
No i dont think he has a claim. Unless you suggest differently.
Thank you very much for your speedy advice.
