Very Efficient

Donovan was extremely professional, offered common sense solutions and completed the work in 1/2 day less than we were quoted! He even took the time to mortar set the tub even though the instructions from Delta said it wasn't required. The attention to detail showed and the new bathroom will be great because of their efforts!

Cody was respectful, personable, courteous, answered all our questions we had during his visit, knowledgeable. Cody helped us get in touch of the appropriate people, to finance the work that our home needs. He helped get the work scheduled so that we wont need to wait longer to get the work taken care of.

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.

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!
