Great Service

We had some plumbing work done by Mainstream. The plumber (Sam) they sent out was GREAT. He listened to what we wanted done; gave us advice about things that could become issues and was very conscientious. We took his advice about our 15+ year old water heater and replaced it. My husband raves about how great it is to have really hot water. We plan to have Mainstream do work for us in the future.

Highly Recommend

My first time using this company for the water heater flush special for $99. Good value. The serviceman Brent was knowledgeable, very professional and courteous. He explained things well. He was friendly and used shoe covers and face mask, even though I didn’t require it. I appreciated the good service and clean work. I also received a follow up phone call from their office after the work was done.

Great Service!

Our water heater was making noises it shouldn’t. Chandler was professional and very knowledgeable. He educated us on the issues and answered all of our questions. I recommend this company.
