DEP Compliance Services

David Gomolka and his partner were Awesome. Very knowledgeable, friendly and Great service. I would recommend Dierolf’s to anyone. Barbie

If you are considering a water treatment system or any plumbing I highly recommend Dierolf. If there was a higher rating than 5 stars, we would have given it. From the sales person Matt, the office staff and most importantly the installation technicians Jon and Dave, the knowledge and professionalism has been outstanding. The work was done in a timely manner. The installation was clean and they made sure we understood our system, how it works, expectations, and their availability if any problems or questions. Exceptional is an understatement!

Dierolf plumbing is a great company to work with. From the initial contact to getting an estimate and having the work completed, everyone was very friendly and professional! Communicated with us every step of the way. Replied promptly to all questions. Kept us informed of our appointment and arrived on time. Justin was very informative and made sure I understood how the system worked and what to do if I have questions down the road. It's a company that truly cares about their work! Highly recommend them!!!

Always excellent service that i trust. Thanks today to David.

David was excellent. He answered all of my questions and went above and beyond to check the many parts of our complex water treatment system. Top shelf service.
