My natural gas water heater created a small catastrophe the night before Christmas Eve. Not only was the hot water heater not working, it had started to flood my basement. I called several providers of service that claimed in their advertising that they were available 24/7. Rescue Rooter was the only one who made someone available to come out at 3 am. Some of the other providers offered to make themselves available in 4-5 days. Dave was prompt, friendly, and took the time to explain everything. He is a rare breed and worth his weight in gold.
