"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."

"Woke up to no water and quickly figured it was a bad well pump. Called Tommy at 6:15 am and he came over to access the problem. Went to plumbing supply and gave us options on pumps. Installed same day and water is running. Very knowledgable and quick to respond!"

"WOW!!! From the initial contact via email we were provided with a detailed answer to every question we asked by Jake's wife, Dawn. She gave us a price for what we wanted done immediately and that price didn't change after the work was done. We knew the exact name and model number of the filter we were getting before we even set up the appointment. We were given the price that included the filter and installation. We shopped around and did further research for a couple of weeks before deciding to get the work done. We contacted Dawn again and she was super helpful and provided the phone number that we needed to speak with Yolanda to get added to Jake's schedule. Yolanda was very professional and worked with me to find a date that worked with Jake's schedule and ours. We knew that they take pride in their company just from our initial contact and setting up our appointment. Our appointment was scheduled and Jake arrived between the one hour time frame we were given. He was polite, professional, and very helpful. Jake installed our whole house filter and cleaned up everything. His work is very neat and professional. Jake took time after installing to go over everything we needed to know about the filter as we took notes. He also let us know that if we had any questions in the future that we could call him or email Dawn. I honestly feel that he truly meant that and would be more than willing to answer any question that came up later. We definitely found the best plumbing service! Jake takes pride in his work and it shows in the business that he runs. We will definitely use A-Master Plumbing for our next project.

"I called at least three other companies. All within $100. in estimates. One plumber recommended a water heater booster because of the smaller 50 gallon heaters available now. I was replacing a 65 gallon heater and when I mentioned this the Casto rep agreed it would help considering the size of my family. He explained the process and answered all of my 'dumb' questions in a polite and understandable manner. After reading the reviews again for the estimates I received I went with Casco. I am glad I did...the following Monday they came in and in about three hours we had a new water heater. The 10 percent discount for Angies Lists members helped bring down the cost to of the the heaters with the booster compared to the other estimates which did not include the booster. We are happy with Casco and I would definitely recommend them."
