Had a great experience with this company from end to end. Great follow up from the office before my appointment, and a great breakdown of the process (including the strength of the equipment, etc).
Rupert and Paul came on time, as communicated, and did a fantastic job. Rupert explained my package to me and explained the difference if I wanted to upgrade - but did not push it at all. It was clear that Rupert and Paul were primarily interested in doing a great job and sharing their knowledge.
Got some great pictures along the way and they often took multiple passes on a given vent if they were not satisfied with how it looked.
They worked cleanly and swiftly, and left almost no mess behind. You don't often find contractors that care so deeply about their standard of work. Highly recommended and would use them again in the future.
