I needed a catflap put in and it was such an effortless process. He came to take measurements, got the sealed unit made and a few weeks later he popped in to install it. He did a really great job and was also very kind enough to take our old panel of double glazing and swapped it into our other door next to it that has blown. Very thoughtful, polite, efficient gentleman and honestly the best price around. I highly recommend. /once again, thank you!
