"Mike was able to get everything accomplished very efficiently and well. He arrived within the expected time window. Replaced toilet seat at no charge. Gave us clear estimates on additional work. As always, so very satisfied with Mike and Servant Plumbing. Know that repair people from Servant are experienced and competent. Find cost of installations for all work, not just Servant, is more than we would expect, but that's where skill and experience factor in. Did not get multiple estimates because we have had such a positive experience with their work in the past."
