DEP Compliance Services

Excellent service! Fast, friendly and most importantly, knowledgeable! I will always recommend them.

Justin just did our yearly service today, and everything was top notch. He was patient with my questions, walked me through the whole process of what he was doing, and was efficient in finishing. Very friendly as well. Thank you so much Justin!

Wonderful service all around. Originally identified issue by testing well water which was quickly mitigated with installation of additional equipment at a fair price. David and Ezra explained the process well and did an expert job with the installation. Couldn’t be happier.

Jon was very helpful and informative about the system he installed for us. Everyone we dealt with in the company went above and beyond for us. Very grateful! Highly recommend!

I’ve contracted and recommended Dierolf for years, there’s no one better in the business. They go above and and beyond every time. Amazing.
