Moved into a new house in August. Decided we were going to swap the electric appliances for natural gas. Called Shipton's, and they sent a lady out to provide a quote. The original quote was $1400 for roughly 150 feet of gas line, plus stove hookup.
We went ahead and bought a stove, and contacted Shipton's to come and do the work. The two technicians were professional and polite. They told me everything that they would be doing, and provided a timeline. While they got started, I chilled in the yard playing with my dog.
About 25 minutes into the job, one of the techs (Nick, I believe his name was) came and got me, and expressed they'd found a problem. He showed me the gas lines running into the house, and the connection to my furnace - all were done with thread protectors, instead of actual couplings. Not only is this illegal, it's incredibly dangerous. After a quick consult with the office to get a new quote, they arranged to come back early on my next day off to start work.
Overall, the scope of the job changed from simply having a line run to having every gas line in the house replaced, with a manifold installed so that each item could be shut off independently (furnace, water heater, fireplace, stove and a spare drop left for the dryer that I'm still waiting on delivery of.)
While it cost far more than originally estimated, that's due to a change in scope of work, rather than any upselling or problem with the company themselves.
I cannot speak more highly of Shipton's, the professionalism of the contractors, or the quality of the work done. Excellent in every regard!
