  • Joel K.

    We had a negative experience from one of the "big names" and were caught in a tough spot. Danny was quick to respond and did what the "big name" couldn't. He showed up on time, with plenty of communication, took the time to explain the entire process, and even went above and beyond to stay late to make sure the job got done to his high standards. Lesson learned: the "big names" aren't the best. First Cast blew them "out of the water" so to speak. We'll definitely use First Cast Plumbing again for our future needs. Thank you!

    A young man named Dan came here and installed a new Water Heater for us. The old one was starting to leak so we needed the new one. I had heard of First Cast and called and made the appointment. NO HIDDEN FEES, it was as quoted! I wouldn’t hesitate to call them again. A+A+

    So happy to recommend our neighbor Danny Dauber with First Class Plumbing! He recently did some much-needed plumbing work for us, replacing old piping under our kitchen sink as well as our well pressure tank and some pretty badly corroded plumbing around it.

    He did a great job! He’s professional, knowledgeable, neat and very thorough. He explained everything he was doing and made sure it was done right.

    We’re always happy to support a local small business, but it’s even better when you can genuinely recommend the person behind it. We’ll absolutely be calling him again for any future plumbing needs!

    Local & reliable. Best around.
