I was so happy with the service I received from On a Roll Plumbing. J.J. Is professional and very kind. Efficient, too, as he had the garbage disposal replaced very quickly. I most appreciated his willingness to talk through my options with me before arriving at the best one, which was also the least expensive. I highly recommend this family owned business.
