      Wonderful company from start to finish! I purchased a new door a few months ago, the quality and the fitting is outstanding. Having an old stone wall surrounding the fitting was not an easy job, however the result is to perfection. Being a family run business they take customer service to heart. I can not fault this company and would highly recommend it.

      This small family company was excellent from start to finish. Then the after sales service was so efficient, Karl was at the end of the phone if the need arose. I would definitely recommend this company and would use them again.
