Rated 4.8 out of 5 stars based on 6 customer reviews

Great service, good price

The service technician was helpful, knowledgeable. The first appointment was not on the schedule and I did not know until I called three hours in to the service window. The technician was polite and offered to stay and finish the recommended repairs so I did not have to schedule a new appointment. I was grateful that he did and he finished sooner than he expected.

Flushometer needs to be replaced it’s opening fine but does close the way it should so it keeps running for a longer period till the flushometer has closed.
