I called to have an expansion tank added to my water heater and for them to replace a valve under my bathroom sink. This in preparation to a house closing. The cost of the expansion tank only cost $50. The cost of the valve is around $10. The job took less than an hour but I was charged $740. I would definitely recommend that you do a price comparison. What I paid was way too much. I felt price gouged.
