Shafer does wondeful work. Diego was polite and friendly. He explained everything.

Dustin was very patient kind and professional with me. He made sure that I understood and was explained everything that I needed to know about the condition of the AC unit. I cannot thank him enough for being so kind with me. I cannot think Shafer enough for the service. I am continuing to save for the extension of my heating system downstairs. Thank you.

Franc went above and beyond with multiple plumbing issues I was having. He found the clean out drain when I could not and cleared the obstruction 60 ft. from my house. He then repaired the rock pathway I had dug up trying to find the drain. He checked faucets and cleared drains in one bathroom. He fixed a toilet and a stuck cold water faucet in another. The whole time he kept me informed and answered all of my questions.

Diego was extremely professional and honest. I’m so glad I found someone who didn’t try to swindle me like others have in the past. I also appreciated his honesty about another question I had. He gave me a realistic answer and explained why it wasn’t something that could be done (I mean….it could but it would be a headache), which was a relief. Other plumbers told me it was possible and wanted to charge me an arm and a leg. I’ve had my tankless water heater flushed annually in the past, so I was happy to hear there wasn’t much buildup. Keep up with your annual flushes, everyone! Preventive maintenance makes a difference!

He took the time to explain everything clearly, answered all of my questions, and was completely transparent about the services needed and the pricing involved. There were no surprises, and I truly appreciated his honesty and expertise. If you're looking for a trustworthy plumber who provides excellent customer service, I highly recommend Frank!
