Ralf sped up his start time for us in order to accommodate my wife's pressing and time sensitive need for a home office. He showed up on time every day and worked very hard - often not taking breaks for lunch. He had high expectations for the finished product and we are very happy with his work. He did most of the work himself but would call in a specialist (plumber/electrician) as needed. The tradespeople he called in were similarly skilled and helpful.
