John Goste did an awesome job. Very professional plumber. He was very honest talked me through every problem that he found and clearly communicated what he would or wouldn’t charge for. Will definitely reach back out to Hosack if they have more plumbers like John Goste.

I would highly recommend John Goste and Hosack Plumbing for all your plumbing needs. He came by and checked out some stuff that wasn’t on the original order and helped me fix some things that was simple to him but has been an issue for me since we moved in. He even took time to show me how to fix an issue I didn’t know about. Honest people. I appreciate their help

John G was very informative and courteous! He assessed the issue ... as it turned out we had more issues than we thought. He explained all the options we could go with. We chose a new toliet and shut off valve. Once installed he showed us the old parts and what could have happened had we not replaced them. This confirmed what we did was needed. He demonstrated the new toliet to show us how it was different than our old one. We were very pleased with his work!
