Very impressed with Jake who came out to give a project quote for replacing my furnace. He was very thorough and discussed all of my options. I'm happy to be working with him and the JCF team. I also was very pleased to have Justin come out to do the annual inspection of my HVAC unit and make recommendations for what needs to be done to either replace or repair the 18 year old system. Both were very professional, efficient, and easy to ask questions. Highly recommend JCF.

I called John C. Flood to help me to resolve a persistent sewer gas smell that was coming from the toilet in the basement of my house. The tech (John S.) who came out to my home was very knowledgeable and professional. He was able to diagnose the problem and explain the what was causing the odor issue. I am very pleased with the service that I received. I would highly recommend this company.

I'm glad I called John C. Flood for a new water heater installation; Jacob was able to come out the next morning to assess and work up an estimate for me with five options, which I appreciated since my previous estimates weren't that detailed. Jacob was super professional and friendly, explaining everything and answering questions. He was also able to match the price of the previous estimates, so I decided to go ahead and he got to work in true master plumber style, finishing the whole job in a few hours. Everything looks great and now I don't have to worry about a 15+-year-old heater going out at the worst time. And yes, my anodes were way overdue for replacing as Jacob happily pointed out! I recommend calling John C. Flood for your plumbing needs, and ask for Jacob George.
