"This company is a treasure! I had a gas leak last week in the heart of the coldest weather in ten years: PSE&G just shut off the gas and left; and Alex was the only plumber who responded, to my urgent calls for help as the house cooled down. He was reassuring, came that day to take a look, arrived punctually with a helper the next day, and did a 3-hour repair (it involved work outside and in a crawl space) quickly, efficiently, and professionally. He cleaned up thoroughly, and left me with heat back on and hot water restored. PSE&G came the next day to remove the red tag and approve his work. All this for a third of the price the big companies wanted to charge me! In addition, he spotted duct work that had been dangerously incorrectly installed on the new furnace and warned me - the company who did the installation has just been over and has agreed to remediate the duct work free of charge. - Alex is fairly young but experienced, a master plumber, fully licensed, and friendly and h"

Customers say: True professional

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

"Keith came out the same day I called and identified the water leak under our hot water heater. He and his son came out three days later and jackhammered the slab and replaced the broken pipe. They then refilled the hole and laid new cement and replaced the hot water heater. Keith then took the extra trouble to re-route and replace the water supply lines to meet code. Now we have hot water and NO LEAK! Other than a slight change of concrete color you can't tell the repair was ever done. We are extremely pleased with the team Keith and his son and highly recommend Blue Boxer Plumbing!"

"Dennis, our technician was absolutely awesome. He explained everything he was doing and why it needed to be done. Dennis also found another small issue we had and repaired that as well. He was organized and a perfectionist. I would hire this company again without a second thought. Also the pricing was very reasonable."

"William came over when we had a leak going from our shower into the basement, and he honestly saved the day! He took the time to really listen and figure out exactly what was wrong, and he had the problem fixed relatively quickly. He was extremely professional, respectful, personable, and just an all-around great person to have in our home. He cleaned everything up when he was finished, and by the next day everything was completely back in order. I was honestly blown away by the entire experience. It’s not every day you come across someone who is so knowledgeable, professional, and genuinely pleasant at the same time. I would absolutely recommend William to everyone! If you need a plumber, call him — you won’t be disappointed! 732-856-4616 best protoday.com is the website! Ask for William"
