Best Doorbell Installation in Cincinnati OH

Came over for an estimate and they were way over double 2 other estimates we got.  Talked bad about their competition and said they used used parts.  Then proceeded to charge a service call fee for giving such a crazy estimate.  The estimator either didn't know what she was doing or they are criminal.  Either way I would never recommend them. $6,500 for a standard water heater?  You've got to be nuts.  I received 3 other quote of the same Bradford and White unit ranging from $2,510 to $3200.
