Mr. Kuttler’s main line of work is installing window treatments for interior designers. As a result of his varied experience he knows how they work and how to fix them. I called him when our 7 feet tall 10 feet wide vertical blinds became hard to operate to the extent that I was afraid I’d break the mechanism. He fixed the problem right away with a couple shots of non-staining spray oil in the right spots (which had easily eluded me) and they’ve been fine since. Recently we called him again when our Roman shades started going up at an angle. To our great relief he was able to repair them and literally straighten them out. We were not eager to sink money in a new set! In addition to knowing his work Mr. Kuttler is a good guy who is easy to work with. If we do have any other window treatment problems it’s good to know that we have a reliable and knowledgeable guy we can call to fix them.
