I used Schoonover to add a gas line to my kitchen when changing from elec to NG cooktop and oven. They did a great job! Came first and did several measurements. Went back to office to do calculations to make sure my existing line was large enough (it was). emailed me the bid. Showed up when they said they would and even though the project took them longer than expected. The guy had to leave and go back to their shop for different parts. They stuck to their proposal and didn't charge extra. The only reason for not getting 5 stars, is they were a little more pricey, but in the end I thought more professional and quality.
