Due to a abnormal July natural gas bill four times higher than usual, we discovered a small gas leak in the gas line feeding the hot water tank which is housed in a out-building to the house. We contacted Master-Tech Plumbing for the first time due to out regular plumber being unavailable for immediate response to our needs. A small two foot piece of galvenized pipe with a small hair-line crack was found to be the cause. The pipe was replaced by unscrewing it from the elbow six inches underground and replaced with a new piece of pipe. Following plumbing codes & regulations, a pressure test was done, followed by inspection from city officials and gas service restored to our residence. Quality & Professionalism: Master-Tech Plumbing was prompt to respond. A plumber arrived the next morning and got right on the job. The leak was found fairly quickly and repaired fairly quickly. The workmanship very acceptable. Price: Excluding the price of the parts for the repair, the hourly rate was 33% higher than other plumbers in the area (in the same town, within 5 miles). The hourly rate was 40% higher than our regular plumber and 33% higher than another well-established plumber in the area. Recommendation: If the situation arose to require plumbing services (which I'm sure it will), and the situation does not call for immediate action, I would wait on my regular plumber, or research for a competitive plumber in the area. I would only resort to calling Master-Tech Plumbing again ONLY if the situation required immediate attention and no other options were available.
