"The Stapleton Team. Made quick contact, scheduled around my time frame, and delivered a skilled tech to solve a basic problem that I couldn't fix. They also recommended additional settings at no cost and proposed other services the company has as a separate fee for service."

"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."

"It went well. We had a previous company out to work on it 3 years ago. The Master Plumber found the issue to be the original home owners did not do any of the pump replacements to code. Also the pipe underground to the well was under code for the pressures involved. He would warrenty his work but only until the old pump. His request was to change it all. Dig a trench to the house and replace it all with stronger pipe. If he could do it of course the price would be higher but he would warrenty for 20 years. While working he would show us all the evidence of why the upgrade as well as the process. Meanwhile his price was pretty good. He gave a flat price in the beginning and it didn't change or fluctuate throughout the process even though a lot of manual labor was required just to get to the original repair area. Overall i would hire them again. I would say they are trust worthy and knowledgeable about their stuff. He punctual for his appointment times as well. All in all 16 hrs of labor, many feet of pipe, and a few dozen fittings."
