"The company technicians, Steven, James and Zack were very professional and competent. They did excellent job in both removing the old unit and installing the new one. In addition to this job, we have used Appleton Campbell for several projects over the past couple of years, to include, installing a back up propane generator, installing replacement electrical lighting, and replacing a hot water heater. The company and their personal, to include both field and office individuals, were very competent and courteous. We highly recommend this company to other individuals."

"Fine. I had no issues. They got out to the house very quickly, within several hours of request, they were quick with no added charges or time, and the estimates that were requested (replacement of water heater) were explained thoroughly."

"Rene, the owner of R-Plumber arrived on time for a Saturday project evaluation and did a thorough professional review. He offered reasonable suggestions about the scope of work, and noted that two of the apparent problems were actually not in need of repair. He was immediately likeable, and although his cost estimate was in the middle I hired him. His assistant Luis worked well through the day, doing a great job on the water heater and disposal install, and although the 45 year-old bathtub faucet replacements took a lot more work than expected there was no complaint or request for additional money. I will use him for future plumbing needs."

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"If I could give 10 stars I would! Our 2 year old hot water heater went out in the middle of the night due to an electrical issue. Tommy came the next morning, identified the problem and explained everything to me. He returned later that afternoon with a brand new hot water heater and installed it. We had hot water less than 24 hours after our heater went out! Installation was professional and I can tell he takes pride in doing things the right way. He was also up front, fair and honest about pricing. Thank you so much!"

"Replaced a well pump, pressure tank and switch. John Dexter was prompt in response and the installation was completed within a couple of days. The young man that completed the installation was very polite and did a great job. Had an issue with a slight leak on one of the tank fittings which did take two return trips to solve the issue which was nothing more than a lack of silicone grease on the o-rings. Two days later we detected a very bad taste in the water. Called Dexter to tell of the issue. John did not seem to concerned and ask me to email him what I was experiencing so he could forward to his water people. The taste and smell were very bad and the water could not be drank. Dexter's shop is literally a mile from my house. I think it would have been prudent for him to swing by and see the issue for himself. I decided after a few days of not hearing from Dexter, to contact someone else to solve the issue. While Dexter Well and Plumbing is fast to respond to the initial problem, they seem less concerned if there are issues after the fact."

"Terrence provided excellent services. He was punctual, professional and courteous. He fixed the clogged bathroom sink immediately and upon my request, showed me how I could unclog the type of sink I have. He also informed me why I wasn’t getting stronger water pressure and what to do to change that. I definitely recommend Terrence and he’s on my list to call whenever I have a plumbing issue."
