I called about my sewer backing up, and they came out within the hour and took less than an hour to fix it. Very friendly, very efficient, cleaned up after themselves and I would definitely use them again!
Patricia H.Phoenix, AZ★★★★★
Our water heater died on a 112 degree day. Baja had a new one installed by dinner. Upfront price, no surprises, and the tech walked me through everything.
Marcus T.Mesa, AZ★★★★★
My plumber was excellent. They scheduled me the same day in the afternoon. I could not have asked for a better plumber.
Brian A.Chandler, AZ★★★★★
Had a simple issue and the tech came the day I called, addressed the issue, and got everything working properly. Courteous and thoughtful. Would call again!

I highly recommend Baja Plumbing. Very efficient. I called in the morning and they came out in the afternoon and solved the problem. Extremely professional.

They installed our walk-in tub and were so patient with all of our questions. Clean, on time, and the senior discount was a nice touch.
