Oct.2025: Service Requested: Repair Leaky rusting Furnace pipe, replace leaking basement slop sink trap pipe, repair outdoor water faucet
* Excellent Service, provided detailed work plan, kept me informed via Calls, Text and E-mails, Arrived on time. Evaluated what I need right now and what I can fix later. Technicians cleaned up after they finished. Prompt Billing, I will definitely hire them for my future major furnace replacement job.
Special Note: The OTHER "Like Named" Plumbing company Ignored my service request.

I had a leak in my living room coming from a room above. First thing they did when they walked in was to immediately put down a tarp so they wouldn't get anything soiled. The problem was Id & addressed. They also installed new sink fixtures in my kitchen. They were fast, efficient, clean working & friendly. I will have no problem using them again when needed.

My water heater needed to be replaced. The team came on time. Both were very professional and great to work with. Replacement was done quickly and efficiently. They even swept up after. Would recommend.

Lou and his Son replaced rusted steam pipes and tuned up our boiler recently. The work was beyond my expectations. I found Lou to be down to earth and "user friendly" throughout the process. He did not try to sell me anything but pointed out how some things need cleaning instead of just replacing them. I will call on him again!

I honestly cannot say enough good things about Lou and his two sons. Lou has been nothing short of outstanding to work with. Due to hurricane Ida I lost my entire basement and all the utilities. I reached out to Lou to give me a quote for a new boiler and hot water heater and he quickly provided a fully detailed estimate with specifications of exactly what he would be installing. I had a few questions regarding the system as well as warranty information and Lou was always extremely responsive with answers and provided me with all documentation that I requested. Not only did Lou do an outstanding job but I think one of his best qualities is how responsive he is. I never had to chase him as he always picked up his phone and always responded to messages in a timely manner. Lou always remained in contact with us throughout the entire process and he always showed up when he said he would. He did a great job installing my new boiler and indirect hot water heater and even suggested installing it up off the floor in order to avoid any future flood damage just in case. The night he finished the installation he even sent me a follow up message at 8:30 at night to confirm that everything was running flawlessly and that I didn’t have any issues. Him and his sons were a class act and I would HIGHLY RECOMMEND using them for any and all future work. Thanks a lot Lou for making the process absolutely seamless and stress free!
