  • We had an outdoor faucet leaking next to our foundation and Steadfast set it as a priority and came out promptly to repair it. Robert and his team are serious plumbers, professional, and friendly. I have added them to my home maintenance and repair teams.

    -Mary B.

  • Stedfast Plumbing has been our go-to plumber for over two years. Robert and his crew have always been responsive and provide excellent service at a fair price. I have and will continue to recommend Stedfast as the best plumber in the Rogue Valley.

    -William W.

  • Very efficient from start to end. Informative and very professional. Stedfast is the team you need for all your plumbing needs! Outstanding service!

    -Mick P.

  • Great communication and did the job perfectly while explaining what they were doing and why. Steadfast is most definitely my go-to plumber now.

    -Adam N.

  • These guys were great! Unclogged 50 ft of decades old gunk in a kitchen drain pipe. Only other option was cut the pipe out and replace it. Price was reasonable considering how many hours it took them. Definitely recommend!

    -Marklan N.

  • Outstanding family owned and operated business. They were the only ones that came out when my main line got clogged with roots. Just great guys and best of all they know what they are doing. I will always call these guys first!

    -Terry T.
