J&K Supplemental Plumbing, Inc.

Very nice and professional. They left my basement spotless and finished the job ahead of time. We will definitely call them again.

I hesitated during this virus to have my water heater replaced, but John and his assistant came in with full masks, gloves, and booties, so I felt very safe. I have already recommended them to a neighbor. His price was lower than the one received by my neighbor by another service.

I would give him ten stars. He did a fabulous job. He gave me a fair price. He filled me in every step of the way. I would highly recommend him to everyone.He cleaned up every day. I think he loved my vacuum. I trusted him with my home. I would hire him again in a heartbeat. He replaced my pump up system in my downstairs bathroom. He had to dig two feet below my foundation. He took out the old shower and installed a new one. He replaced my sink. I told everyone in my family if they need plumbing work to use him.

I had a 40 gallon water heater burst and reached out to multiple plumbing companies. John was the first to contact me and understood the urgency of the situation. He was extremely professional, explained the "who, what, why" of everything that could, should, and would be done and provided all possible options for replacement with 4 different quotes. I hired him and he singlehandedly replaced and upgraded my water heater with zero issues. Keep in mind this all took place in a 24 hour window. I WILL be using J&K again for ALL of my plumbing needs. CANNOT RECOMMEND ENOUGH.

John is a pleasure to work with: polite, accommodating, respectful of one's property, always keeps appointments, leaves everything neat and clean, and does excellent work. In other words, he's a gem and I recommend him without reservation.

This is an update. Have to have sink and tub plumbing redone. Tub doesn't drain because it actually runs somewhat uphill. For both sink and drain went from 1 1\2 to 2"and back. PLEASE DON'T USE IF U HAVE A HOUSE OLDER THEN HE IS, I'm having work redone for 1/3 of price. He disconnected pipes from the vent leaving me with a loud gurgle. The minute I raised the issue he became very defensive. He has never acknowledged removing the plumbing from the vent. When I tried to get him to fix it (there is an unused vent 5 feet away) THEN HE STOPPED communicating with me. Please don't use him if you expect him to resolve issues with his work.

John was very informative, clean and thorough with is work and would highly recommend him

Honest, trustworthy and super clean. He did a great job!

Put in new shower heads that met our needs. John was on time, gave us a fair price, left area very clean and wore booties over his shoes. Very congenial person. When he came to give us an estimate we explained our needs and he gave us choices as to how it could be done and gave us the pricing. Work was done as specified and pricing. Would recommend him and we would certainly hire him again..

Very Polite, and cleans up everything. He even puts covers over his shoes. Did a great job knows his work well.

Great service neat clean and professions

John was very professional and courteous. The estimates he gave me were lower than others and he explained the whole procedure very accurately, including what could happen so there were no surprises. Thankfully , the worst did not happen and John finished quickly. I will be hiring him again. Thank You, John.

I called with a "no water " problem In my home. They showed up on time the next morning. The technician found that we had a faulty switch in line with the well pump and tank. He did not have the switch with him and had to come back the following morning to replace. This was a little inconvienant. They also charged in my opinion to much for a pump switch and install. Overall I am happy with the service. I might look for a second or third quote next time.

very helpful ,professional I thought about 4 different valves needed replacement on my boiler , turns out it was only 1 all the others just needed some TLC ,maybe if I had gone with someone else it would have been all 4 ,honesty and trust go a long way in my book .I WILL DEFINITELY BE USING THEM FOR ALL MY FUTURE PROJECTS !

Job was difficult, John was professional and fair with his pricing.

Work was well-done and neat. Price seemed a little high, but may be in line with what another plumber would charge.
