Very personable and patient!

Both technicians that came to our home were great! They were very personable, and very patient. My mother in-law has a hard time with her English, as it is her second language, but they were both very patient with her, and made sure she understood everything that needed to be done. On their customer service alone I would recommend this company. We live in an old 1980's trailer which made it hard to find parts needed to fix our heating system, but they did all the research they could to try and find the parts needed. I am so glad I decided to call Mainstream Electric and will continue to use their services in the future.

Same-day service!

Able to obtain same day service to troubleshoot a hot water issue. Technicians showed up promptly and wore masks, gloves and foot covers. Thoroughly explained three options for resolution in a professional, no pressure manner. I highly recommend this company.

Amazed

Our home is 66 years young and it was time to replace the original water lines and sewer lines. I was amazed that they were able to streamline, fix old plumbing mistakes and make our entire water system user friendly. Thank you Cody, Donovan and the third guy that I can't remember his name. They were all professional, polite and knowledgeable.

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!

Respectful

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.
Theresa J.

Knowledgeable

I had Mainstream come out for an annual inspection of my hot water heater. After the inspection, it was determined that the water heater needs to be replaced. The technician, Cory, was very professional and made all of the necessary arrangements. Later the same day, Shane came out and replaced the water heater. Shane was very professional and knowledgeable. I am very pleased with the employees and the work that was completed by Mainstream.

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.

How do you know you need water heater repairs?

Other than not having hot water, what are the telltale signs?

Water temperature is too cold or too hot

Temperature variance in either direction can be a sign of a water heater on the fritz. Water heaters rely on thermometers to regulate water temperature, so scalding hot water can be as much of a water heater issue as freezing cold water.

Hot water has a bad odor

If you notice an odor that only shows up when the hot water is on, you may be dealing with bacteria build-up in your water heater. This is not always an issue that requires repair or water heater replacement; call Mainstream at (866) 411-9277 to learn more about our water treatment and filtration services.

Visible issues with water heater (rust, leaking water, etc.)

If you’ve identified obvious problems with your water heater, from leaking water to rust or any other problem, don’t hesitate to contact us! We’ll come diagnose the problem and give you an estimate for repair services (or recommend a water heater replacement if necessary).
