DEP Compliance Services

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.

Very very helpful and nice people! Wow i thought companies that care were gone not so!!! Dierolf’s people care and i think it’s a real reflection of the owner and how he runs his company and actually cares!! Thank you for a super great job and for caring!!

I have been using Dierolf since a friend referred them to me years ago. Scheduling is always quick and easy. Kelly always answers the phone with energy and if a call back is necessary, you know you’re getting a call back. John came out to install a brand new water system in our home. He was very professional, friendly and outgoing. It was an all day job. They left the area as clean as it was when they got there. At the end of the 8+ hour day he answered all of my questions and showed my husband and I exactly how to use the system. I never felt rushed with any questions I asked. I would highley recommend if anyone is looking for a plumber. They also charge a flat fee for service calls - so while they are out to service our system yearly they will bring us a supply of rock salt for the water softener. Today Bryan came out to re chlorinate the lines and it was super friendly, courteous, professional and knowledgeable. He listened and answered all of my questions. He was in and out with what he had to do. I cannot think of 1 negative thing to say about my experiences with this team.

They were able to get someone here before their scheduled time which was nice and i was able to get on with my day accordingly. Bryan was very helpful, knowledgable and able to help me out.he made a suggestion to help solve a potential problem. I would highly recommend Bryan and Dierolf plumbimg. I want to know who ablie rettew is as that is what showed up in my caller id when thru asked if they could come earlier than the scheduled time

David worked very hard to put our new UV tube in to continue to purify our water. So thorough and professional. David also delivered 8 bags of salt for our system located in the basement (it is no easy task)! Thank you very much for keeping us safe. We appreciate you!
