“Mike was extremely professional and explained everything before he did the work. Mainline sent him immediately and we also received the Senior Citizen discount which helped out with our bill. Mike was a great plumber and explained he comes from a family of plumbers. You’re in good hands with Mike and the local company Mainline in Londonderry, NH. Thank you for our blessing in disguise”
“Mike was fantastic! He was on time, informative on the issue, and knowledgeable on the best solution for our sink plumbing. He provided us with a great recommendation for the solution to plumbing work. Will not hesitate to contact him again. We’ve already recommended him to our friends and family.”
