Roller Door would not rise. Phoned and Stuart said, be there 9 next morning. Arrived at 9. Stuart quickly stripped the door housing down, explained what was wrong and quoted a price. He then said that he would bring the parts needed, returned in an hour. As he progressed the repair he showed me the worn part. and explained the problem. He worked quickly & obviously knew what he was doing. All back working in 4 hours. Excellent professional work.
