Real Reviews

Kathi H.

The receptionist was very kind scheduling my appt for the same day. Kieran, the plumber was very courteous, covered his shoes, and knowledgeable about the process, procedure and cost. He protected my floors under equip, and cleaned up carefully after. Thank you for your service.

Anastasia R.

Mainstream plumbing saved the day for us when they sent out their journeyman plumber. Brant was punctual, professional, and extremely clear about the repairs we needed and the amount those repairs were going to cost us. I will definitely call them again for any plumbing repairs we may need in the future .

Sam C.

We’re adding a new building with a dedicated water line. Cody came and bid the job at a fair price. Within 48 hours, their techs were in a five foot hole making complex connections without any problems whatsoever. I called several plumbers, and Mainstream was by far the best priced and most professional.

Dylan H.

Brent and Taylor are great people and great plumbers. They knew what they were doing, took their time explaining the process to me, and displayed great customer service throughout the entire experience.

I would highly recommend Mainstream for my plumbing. They cleaned up all the mess and made sure everything was working and marked clearly.
These two guys made an awesome team.
