Maxx and his team were great! They came out the same day and were able to fix everything, even in the cold rain. They were very professional, knowledgeable, and personable. They answered any questions and explained everything. I would highly recommend Dopp Pump Company! They were the awesome!

We had Dopp Pump Company come to our house to replace a well tank. Maxx and his partner diagnosed the problem, gave me a quote, and replaced the tank all in the course of a few hours. They are knowledgeable, personable, quick and very clean. I have never had a better experience with a repair crew. They will be my go to with any well related issues from now on. I highly recommend this company and Maxx!

The guys at dopp plumbing were very friendly and helpful. They got us back up and running right away and were so great with communication and making sure we understood all the work that was being done. I highly recommend this business and will plan to use them again for any future needs that happen to arise.

New well installed and not an easy job considering location of home and lack of sub-floor space to work. Maxx and crew were professional, never missed an appointment, punctual and never failed to notify if they were to be late. Maxx kept me up to date as the install progressed and was always willing to answer my many questions and follow up after the install was as promised. Dopp pump Co has been in the community for many years and this is a testament to their quality of service. I found the company through a referral and rate their service as 5 star.

Dopp is the best! They were able to fit me in at a moments notice and were able to replace my broken well pump in about an hour. These guys pulled out all the stops and were very knowledgeable and professional. If you are looking for a fantastic company to do business with, look no further!!! We are so happy to have our water back!

Dopp pump was awesome, we recently needed an emergency well tank replacement. Made the call and max and his team were ready to come out that day to fix! Couldn’t recommend a better repairman for the job.. he even offered advice and info on questions I had for other repairs in our home. These guys are smart at what they do, very kind and professional.We will be using Dopp pump for any well-related issues we have in the future.

I'm so glad I made the call to Dopp. I called Max late in the afternoon. He and Eric came by the following day. Listened to the water problems we were experiencing, checked out mechanicals and quickly identified what needed to be done. They showed up the next day (when they said they would) and began treating our well, which was followed a second day with a new pump, pressure tank and some plumbing alterations.These guys were both very professional, stayed on task and treated my wife and I like we were their only customers. By the way, the bill for their services was fair and within the estimate given prior to beginning the job. It was not only fair, but far less than an estimate given to me by another local competitor, whom wanted to convince me that I needed a whole new well before ever stepping foot on the property - and then never followed up. Bravo Max and Eric!

Max and Eric are awesome! We had a leak at our well head and they came out only a few hours after our initial call to inspect it. They diagnosed the issue and came out the following morning for the repairs. In typical home repair fashion, one thing led to another and we found out that pretty much the entire pump system had to be replaced. Not even 48 hours after our call our system is up and running again in perfect condition. Dopp Pump is professional, detailed, and willing to go the extra mile. Highly recommend!!!
