Customer Testimonials

The job involved a complete gutting of my master Bathroom. From walls to ceiling, to floor ! With the addition of a whirlpool one wall had to be moved. None of the existing plumbing remained in its original place. Marble from floor to ceiling, new lighting, a separate shower-on top of it all the original contractor that i'd hired cancels on me at the last minute!!! Noticing an ad in a local paper claiming that an actual plumber would call back within the hour i took a chance. Lo and behold-a plumber actually calls. Showing up on time and clean was indeed a surprise! What really impressed me was how professionals and courteous he was and i hired him on the spot. The real surprise was the quality of work! They really took care and made sure i was happy. Needless to say-my new Bathroom is MAGNIFICENT!!! I can't say enough good things about Big City Plumbing & Heating Inc.
!!!! Hire these gentlemen now!! I guarantee you'll be totally happy!!!

We contacted Big City Plumbing to convert our oil boiler into a tankless gas boiler and foam the oil tank. Mike provided a reasonable quotation for the estimated cost for the service and Diane could always provide prompt answers to our questions/concerns. Considering the good reviews on line, we signed the contract with them. It proved that we made the right decision.
Benny and his team carried out the boiler installation project. Benny is very professional, polite and efficient. They arrived at 8:00 a.m. and started to work immediately. In 2 hours, they removed the old boiler and by 3:00 p.m., they new boiler was installed. They also cleaned the laundry room after the project was finished. The installed
gas boiler looks really awesome. We are very satisfied with their service and we strongly recommend Benny, Mike, and Diane to all!

I had to have my hot water heater replaced. I thought the estimate was too high, but after speaking with Mr. Polidoro I realized he was giving me the best equipment money can buy. I had the choice of going with something cheaper, but I did not want any problems down the road. He was very professional and honest explaining everything to me in detail. I would recommend Big City Plumbing, and would use them again if I have to.

This is the way a professional company is supposed to run!!
Mike is a 1st class man, he helped me out of a real emergency, seamlessly, happily, above and beyond what anyone else would, with a smile and a great attitude. His ability to diagnose and resolve my plumbing and heating issues was fantastic!! If you can get an appointment don't hesitate, you will have a top company and a great man for life.!! Thank you very much! John Z

We called Big City Plumbing to have a tankless water heater installed after our existing tank broke down. Mike was prompt and very knowledgeable, Diane was pleasant and helpful throughout the process, and Benny and Corey did a fantastic job installing the unit, even replacing the wet sheetrock wall. They were cordial, efficient, thorough, and especially concerned about our safety. We highly recommend this very professional organization.

I have nothing but good things to say about this company. They are prompt, efficient and courteous; very professional. I highly recommend.

I called to have my hot water heater replaced and they gave the best price. The woman on the phone was courteous, friendly and extremely helpful. She made a quick appointment to help me out. Benny and Lou showed up on time and ready to work. They were professional, efficient and worked clean. They finished in an hour and a half. They did an amazing job. The bill was exactly what they said it would be. I cannot give a higher recommendation.

Mike was wonderful. He was professional and personable. He worked on our problem during the Christmas holiday when others would not. We will be very happy to call him in the future! Keep up the good work, Mike!!! We love you!

Should've called these guys first. Nothing but professional, knowledgeable, great customer service, fast, and great prices. Will absolutely use them again in the future. They took a 1/4 of the time to fix my tankless water heater and it cost me half as much. Benny was my plumber that was sent out and knew exactly what the problem was before he called the manufacture for required troubleshooting help. Nothing but professional. Overall perfect neighborhood plumber.

What an excellent decision it was to go with Big City Plumbing! Mike makes the sale (and provides the humor :) Diane keeps all the balls in the air (Mike, what would you do without her?) Benny and Corey do the installation (Two of the nicest guys you will ever meet!). Together they are a great team who I felt was not only very knowledgeable and professional, but also very honest, praise God! I was very comfortable with them throughout the entire process of changing over from my old oil-fired boiler to the brand new gas-fired Navien NCB 240. The installation is very professional (Thank you Benny and Corey!) and we are thankful for all that the wonderful folks at Big City Plumbing did for us. I highly recommend them to you!

Working with Big City Plumbing is a smart decision for any business owner looking for a fair and honest experience on a residential or commercial gas conversion.

Had a problem with our hot water, Mike came over and did a fantastic job in the repair. The price was a little higher than we would have liked to have paid, but you pay for what you get, great service and 50 years of experience. Great job. Thank you

Several years ago I hired Big City Plumbing to complete an oil to gas conversion.
They did a fabulous job.
Since then, I have had other issues arise, not related to the boiler and needed a plumber.
Each time I called Big City Plumbing, they responded immediately and the repair remedied in a quick and efficient manner.
I highly recommend Big City Plumbing. Mike, Benny and Diane are all great.

I needed plumber to do a small job that had to be done within 2 hours. Despite their busy schedule, Big City Plumbing & Heating Inc.
called me back and fit me in. They understood my situation and really helped me out. Mike P. was cooperative and efficient. He did a great job.
Thank you
