Thank you for your response, your terms state "Please remember that, by fitting or finishing your door or making alterations in any way, you will be deemed to have accepted the goods as supplied. Unfortunately, we cannot replace a faulty or incorrectly supplied door if ANY alterations have been carried out.". Since the faults were only discovered once the doors were cut, hung and finished we understood that we had "accepted" the doors according to your terms and had no recourse. Additionally, the cost of hiring the carpenter to fit new doors meant that replacing the faulty doors would be prohibitively expensive.
