"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"

"This morning we found out our water heater broke and Good Tiddings responses to our request within ten minutes. Anthony was very responsive and got someone to our house within two hours. Brian was helpful and did a great job getting everything fixed. They gave us a few instructions on future maintenance so our new water heater will remain functional. Everything was resolved within a few hours. We will definitely use their services again!"

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."

"I have a 4 family house in Plainfield NJ.  One of the apartments sprung a leak in the ceiling.  We figured out it was the hot water pipe and had to turn off the hot water to all four apartments Thursday night.  I called Rob Friday morning and he was at the house in an hour!  He quickly checked out the situation and realized what needed to be done to repair the problem.  We discussed the problem and he quoted a reasonable price.  Rob performed the needed repairs on the spot within 2 hours.  I was very happy with the professionalism Rob displayed and would absolutely recommend his company to a friend.
