I am a retired female and ignorant of plumbing costs. I had a garbage disposal and a new valve in five sinks installed. The process took about 3 hours and the bill was $3,053. The disposal cost was $1,050 and I have since learned that the disposal can retail for about $100. A board member at our condo association was dismayed at the cost and talked to Gene Johnson Plumbing and they refunded $661 towards the valve cost. I emailed the company requesting some relief from the disposal cost and have heard nothing to date. I appreciate everyone must make a profit but the job wasn't brain surgery.
