    Capital Well services our water purification and Filtering on a yearly basis. The service is professional and they test our water for quality, consumption and general use and make recommendations to improve the service. We are quite satisfied with the service.

    We had an emergency situation on a Saturday morning, Nick was there to fix it and gone all before 10am! He was very knowledgeable, took his time to explain what happened and how he was going to fix it. Also a plus that he was great with our nosey dog and two young kiddos. Can’t recommend him enough!

    I recently had my well water re-tested after a year of periodic use on a newly built home. Scheduling the test and the follow-up after the results came back couldn't have been smoother. Both Jake and Alex responded promptly, and Alex explained the water test results clearly. They answered all my questions, and I now understand my system and the water it produces better. Would highly recommend Capital Well, and I'm happy I chose them to install my system.

    You really don't appreciate the modern convenience of running water until it disappears! Monday morning we discovered we had no running water and by Tuesday afternoon it was flowing better than before! Capital Well came to our rescue with a new well pump and a new pressure tank. The field crew was responsive, professional, and thorough and the customer service calls were just as satisfying. Thanks to Capital Well for a great experience! I'd highly recommend!
