Mainline did an amazing job installing our water systems! They were professional, knowledgeable and you can tell that they take pride in their work. Reasonable pricing and John was very good with communication as well- super easy to work with! Thank you mainline, what a difference our water systems have made. 10/10 would use again and recommend.

Mainline Plumbing came through in spades for us! Within one day, our new water treatment system was functional, leaks addressed and they carefully reviewed our system with us so we may maintain it properly. The guys were kind, careful and conscientious. I recommend them without reservation and we will use them in the future! Great price and excellent service!

My boyfriend said he could fix the garbage disposal. He broke it. Called Mainline and they sent Mike E. AMAZING service. I never knew plumbers were that professional!? The whole appt was great. Mike is extremely knowledgeable in his craft. You guys have an incredible asset with him. All the tips he gave my boyfriend about basic plumbing. Def will (need to lol) use their services again.
