We had an electric stove and converted to gas. From the first phone call to schedule a visit for an estimate to the completion of the work, it was a pleasure to work with Crisafulli. They only use the black pipe for gas, which I like, and charge about the same as other companies do for the flexible pipe. Crisafulli kept in contact, letting us know when to expect their arrival, and completed the job quickly and with no issues. We'll be using Crisafulli again.
