Showed up for estimate and provided written estimate on the spot. They were too busy to get right to me when I called to accept, but was able to show as promised. Installed the line in one day and left for the inspector a ready system holding pressure. Came back to perform hook up. I had wanted them to tap into an existing copper tubing line, but they informed me of some risks associated with this and that they preferred not to touch that system. Ended up going with their recommendations and feel it was best. Wife impressed with their finishing touches: cleaned all fingerprints off stainless steel, finished assembly of range itself.
