"Enjoying our new water treatment system. Our old one was leaking. Now we have a new stainless steel system in our basement. Our salesman, Scott, was very friendly and helpful. I would recommend this company to anyone who us interested in a water treatment system."

"We have used Quality Water on two different occasions. Zach on the first appointment and Timothy on the second. They both were very professional, knowledgeable, and courteous. They both explained how our water treatment system works and didn't try and push other things that we didn't need. My wife and I learned more from them, then we did from the company who installed it 15 years a go. We highly recommend this company. Thanks again for the great service."

"Excellent communication via text and email so you know exactly when your service technician will arrive. Tommy and Duncan were very polite and professional. They looked over the main water shutoff valve that I wanted to replace and then explained what they were going to do and how much it would cost. Completed the work promptly and cleaned up the work site before leaving. I would highly recommend DB's Plumbing and Drain!!"

"Excellent service! They were able to come out the day I called to evaluate our well that evening. They were able to a**** the problem and detect exactly what the root cause instead of masking it with a water filtration system as another professional had recommended. Dexter's plumbing went above & beyond helping us and we greatly appreciate it. We highly recommend them."

"The estimator/sales person and technicians were top notch. The estimator worked with me on the system requirements and the cost of a new heat pump system. My old system was 20 years old so that the heat pump and inside air handler had to be replaced. Also replaced the thermostat for good measure. The technicians did an excellent job with the install, neat and professional. The system has been working really well. Overall, I believe that I received excellent service at a reasonable cost."

"I definitely recommend Tommy and his crew. Our well pump stopped working and we didnâ t have any water. Tommy came out and determined what was wrong for free, gave me an accurate estimate. They were able to replace everything that day and get us water back. They were good natured and hard working, finishing the job in the dark. Came back the next day and cleaned out all our faucets, clearing the sediment stirred up from the new pump. All things considered, it was a very positive experience."

"Expected Snell to be one of the higher bids, based on all of the good things I head heard/read. They came back with very competitive pricing for Lennox gas furnace and air conditioning systems which they installed quickly and professionally. Great experience."

"Curtis Ashton is a one-man plumbing service and I like that. His work for me was excellent and his price was very fair. He was the first plumber to call be after Angi recommended three services. I will use Mr. Curtis’ service again when the need arises. Highly recommend."
