DEP Compliance Services

Mark was very informative. I was lucky to have his expertise on hand to help me make an informed home purchase. Addendum: About a month or so after our new well pump was installed, it failed. Mark was available on the phone late on a Monday evening to troubleshoot, and when all failed, his team was out the next morning to replace our pump with a new one. We couldn't be more please with their attentiveness and quick response.

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

Very professional. Highly responsive. Excellent service. Competitive pricing. My well tank was on its last leg and needed to be replaced along with the plumbing connecting it to the water feed. Bryan showed up on time, had the parts in his truck, and knocked the job out in a couple hours. I highly recommend Dierolf for all your plumbing and water treatment needs.

I can’t say enough about this company.I used them in a recent real estate transaction and everyone that I dealt with from the owner, to the salespeople, the technicians and the office staff was responsive, friendly, knowledgeable and professional. A++ company. Highly recommended.

We are very satisfied with the 2 gentlemen who installed our water softener. They arrived promptly at 8 and worked quickly to complete the installation. They were pleasant and answered all of our questions thoroughly. They cleaned up and left no trash behind. We would highly recommend Dierolf Plumbing and Water Treatment, LLC.
