"The job was to replace a defective valley gutter, which had been lined with an unsuitable membrane and poorly formed. Mike was able to identify how to solve the problem, including reforming the gutter profile and using an appropriate code of lead. We were very pleased with the resulting work, completed as he had proposed. He was well organised, completing the job in good time whilst maintaining a good quality of work. If we need any further leadwork done in the future, I will definitely contact Mike."
