"I had a tankless water heater installed. I gave 4-1/2 stars for overall rating because the worker who came was the lone installer and had no one to help. I could not use water for almost sever hours an inconvenience since job was estimated to be "about 4 hours". I think he took a deserved lunch break for about an hour. He was on time and was courteous and pleasant. Would have been nice if he had a helper."

"I hired Aqua Smart Plumbing because I had no cold water to my second floor apartment. The plumber diagnosed the problem, which was in an area I thought could not have been the cause. He was right, and I was wrong. He replaced the needed pip and valve very efficiently. He also fixed the toilet on the second floor, which had a malfunctioning water valve. The final thing we worked on was replacing a defective cartridge in the shower. I was very pleased with the work. I would hire them again if I needed a plumber."

"Excellent work. The same day that my 40 gallon Whirlpool hot water heater stopped working I was able to have Four Seasons install a new Rheem (short) 40 gallon hot water heater."

"My old hot water heater died, and a friend installed a new small 40 gal tank. But I never had hot water after that. I also had a leaking lead pipe. Patrick came and had to be a sleuth to try to determine the cause of the missing hot water. The tank was too small and not functioning, but the real problem was a crossed pipe somewhere in my 1890 house. He found the pipe location in the basement and put in a shut off valve, which gave most of the house hot water. He also put in a high quality 50 gallon tank, and repaired the leaking lead main. To completely fix the hot water, it will mean opening walls, so we left a small 1/2 bath sink and attic sink to be fixed at a later time (or not....).. This was all around Easter, but he put in long days to get it all done."

"It was a pleasure to work with Patrick to have our tankless hot water heater installed. We were looking for a small unit as we don't need anything big, he was very accommodating. When work began he noticed the only way to access our water turn off was in our crawlspace, he offered to move it above the floor, we did. Great experience."

"Chis did an outstanding job replacing my 17 year old water heater. He was very professional in explaining how the water heaterâ s performance has improved over the years. He removed and installed a new water heater and brought the water lines up to the current code. I definitely would recommend Cab Plumbing for your needs. I plan on using them for any future needs"

"Tim and his team exceeded every expectation I have. I am an educated consumer of home improvement services and have contracted for numerous projects over the past 10 years in a 100 year old bungalow. The TDH team was the easiest and by far the best to work with of all contractors. They responded within an hour to my initial request and was on site the same day to inspect the site and assess my needs. We discussed numerous options at all price points and decided on a complete replacement of the water heater, hot water heat boiler and the piping. I had final quotes in less that 3 hours and they responded within hours with any question I have. They were able to schedule the work within 2 weeks. The On-site team of Chris, Bernie, and Zeorge also installed a two zone system with computerized controls attached to two smart thermostats. The work was scheduled to 2 days of on site activity. The team arrived exactly on time, 7AM,on the scheduled day. They laid down drop cloths and 100% of all debris and trash was removed. They were completely done by the 2nd day, on schedule. When the work was done, the job site was spotless, Chris did the walk through and review of all the new equipment, answering every one of my numerous questions. The work was flawless and neat. Very professional. Tim, Jim, and his team set the standard for how contracting work should be done, from the first contact through the end of the project."

"I have had CJ Plumbing do work before and they were excellent. This time they replaced my 3 sump pumps because they were too weak to eject the water from recent heavy rains. They acted professionally, did high quality work, explained every step they were going to take during the install, explained the pricing and communicated frequently. In summary, these guys are top-notch! I will definitely use them again!!"
