"Paul did a great job, as usual. I had an outdoor water faucet that's been steadily losing water pressure, to the point that it was mostly unusable. The problem was a clogged galvanized section of pipe, which he replaced with proper copper piping. He also found a small leak that I didn't even know about in the basement pipes. He replaced a crazy looking shower arm/head with something that now looks like it was installed by a professional. He checked the bathroom and kitchen sinks for any leaks and replaced a jiggling handle on a toilet that was causing it to run after flushing. If you're looking for a great plumber, look no further. Paul is honest, has very reasonable prices, he's very responsive, and he's truly a pleasure to deal with."

"My son owns a rental property in Old Bridge NJ. Although he had it inspected prior to purchase there were a few plumbing issues left behind. In his efforts to repair those issues promptly and correctly, he hired MrFixit CNJ Home Service located in Manalapan, NJ. Rob at MrFixit was very helpful and sent a technician. In the end everything was done properly, fairly and even included a discount! We are very pleased with the great service and fair pricing! Services: Find & repair leak, Repair toilet"

"Raymond and his crew did an excellent and outstanding job installing a new water heater. Very professional and courtesy. Showed up on time, proposal was great, explained every detail and step, installation was flawless! He was even available at midnight when we thought there was an issue but realized it was no issue at all and he was ready to come to the house regardless! Couldn’t ask for a better service and company! Will use in the future for other plumbing needs! Highly recommended!! A Thanks again!!"

"Work was fine, but seemed kind of expensive, around $225 to replace one part in a toilet. I didn't get any other estimates, so I don't know if that was unusually high or was about the going rate for such a job."

"We moved to new house recently and found that water heater has stopped working We called many plumbers to check the issue but everyone asked to replace it Andrew Stewart took a pragmatic approach to first try to clean the plate underneath and purged the gas, checked the gas pressure. His expertise lead the water heater started working again without having even a single part replaced. He waited patiently to check if everything going fine for another 45 minutes Thank you for your service, keep up the good work."

"I needed to have the hot and cold shutoff valves replaced in the laundry area, Two other plumbing companies quoted me prices higher and said the wall had to be cut. Chris from A.J. Perry arrived and said he might be able to replace the valves without cutting the wall. He did, in fact, replace the valves without cutting and wall. Chris was the nicest service person I dealt with in a very long time."

"Keith was quick in responding to my request for a replacement hot water heater. He came to the house and gave me an estimate from the purchase of the unit to the installation. He ordered the unit and we scheduled an appointment once the unit was available - just a matter of days. Aaron and Travis did the installation and were courteous, knowledgeable and professional and cleaned up after themselves. I would highly recommend Blue Boxer Plumbing and will definitely use them in the future if needed."
