Very professional, very knowledgeable, very prompt, very patient, Did a awesome job installing the tankless water heater that I wanted installed. Read one of the reviews that said, "Need a plumber.

"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi!"

"Tommy was professional and knowledgeable. He arrived at both appointments on time and got the valve and water heater replaced quickly. I would highly recommend them. I comparison shopped two other plumbing companies during the day and DB's was the best in knowledge and price."

"1 crew dropped off the materials and the installation crew showed up an hour later (on time). There were two men that completed the entire new AC and Heating installation. Took them well past sun down, but they only ever left one time for lunch and stayed until the project was completed (about 930-10PM). They installed the new thermostat and took time to go over how to use it/set it and gave some tips on best practices. Very helpful. They cleaned up the entire project area once done and allowed me time to inspect the site before leaving. Excellent job. Only one (minor) mark against them was the removed the fence on the side of the house closest the the AC unit without ever asking permission to do so. They did, however, reinstall the fence once completed and the fence is as sturdy as it was before the removal. I get why they did it as well, but asking would have been preferred before doing so. I would strongly recommend this company to my friends and family and to you the reader."

"Repairs done in timely manner. Frank explained whatâ s wrong and expectations on how long can the water heater last before possibly replacing it"

"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."

"We called DoneRite after the water heater replacement company fiddled with the Town’s water supply end and somehow caused a blockage that shut off water supply coming into our house. Willis and his assistant arrived promptly and were confident in their assessment of the situation and their proposed solution. They were courteous in their interactions and also said that if their solution did not work then they would not charge us. The Town had informed us the previous day that they should be contacted first to come and shut off the Town end of the supply for any repair work. Willis was respectful of this request from us and waited patiently for half an hour for the Town to send their people. Willis suggested a replacement for our main water valve (which was very old and stuck), and also got our water supply back quickly. They also ensured that they had our new water heater turned on and running before leaving. We will not hesitate to contact Willis for any of our plumbing needs."
