Came out on a Saturday morning to provide an estimate, we provided 50% deposit. On the following Monday, the scheduler called us to set up an appointment for the install. Installation was on Wednesday (2 days later to fit our schedule). They got the city permit ($200 from Chesapeake-ouch), showed up on time, completed the work and set up the apparatus for the city inspector. Very professional, helped us out with another gas issue (no charge), left no mess. The city inspector showed up the next day(Thursday), project passed with no problems. Gas Specialty people showed back up to finish the install that afternoon, hooked up the stove, reset our water heater and furnace. Everything worked beautifully, no problems. Cooked supper on the new gas range that evening.
