I can't say enough good things about Mainline Plumbing! I called John on a Sunday when my heating system started flooding my basement. Thankfully, he lived nearby and was at my house within minutes to stop the flooding and prevent even more damage. His crew returned the very next day to make the necessary repairs, and everything was handled quickly and professionally. Their fast response, reliability, and excellent customer service were truly outstanding. I highly recommend Mainline Plumbing to anyone in need of an honest and dependable plumber!
John and his crew were very concientious, fair and professional. We upgraded some 30 year old piping entereing the home, added a sediment and carbon filter to remove cholorine and added an outside line to the pool house to neaten up the hoses outside. Very happy with the results. I really like working with companies I feel I can trust.
Trusted, professional, and highly knowledgeable! Mainline Plumbing was recommended to me by a trusted friend when I had an issue with my filtration system. The company that installed the system told me it would be weeks before they could come out, but John came out the very next day and solved the problem within minutes. We also discussed Londonderry’s PFAS issue and the best way to address it. John was professional, honest, and extremely knowledgeable. I highly recommend Mainline Plumbing and will be using them for all my plumbing needs in the future.
