DEP Compliance Services

Very friendly, honest and reliable services. Jon K. did an amazing job with the replacement of my hot water tank. Highly recommended for all of your plumbing needs.

You won’t find anyone more knowledgeable about water and passionate about providing great service to his customers than Mark Dierolf and his top-notch team. John and Ernie did a terrific job installing my system and took great care to educate me along the way. I highly recommend Dierolf to anyone in need of consultation and installation of a water system.

Bryan was amazing! So pleasant and helpful as well as incredibly knowledgeable. Would recommend this company to anyone!

We have had a problem with our kitchen faucet leaking. One plumber walked in and just looked at it and said it could not be repaired. He said the only option was replacement and wanted $675. We contacted Dierolf Plumbing, who have done other work for us in the past. They sent a gentleman named Jon. Jon checked it out and said "l am going to another job near a plumbing supply store. I will try to find the correct part for this repair for you." God bless Jon, he found the part and replaced it. Our faucet no longer leaks and it was less than $200. We cannot thank this young man for going the extra mile to help us out. We highly recommend Dierolf Plumbing to anyone who needs help. Thank you!

Excellent Service. Kind, informative, timely, honest and they are super easy to deal with for scheduling and payment options. Great company from top to bottom!
