Fixed After Drainpipe Came Loose
We had the drainpipe come loose under the kitchen sink. Guarini Plumbing was able to fix it and in the small window of time my wife and I have on weekdays. My wife is a school bus aide, and I am a school bus driver. The garage is an hour away from home. Whatever needs to be done at home on a school day must be done between 10:00 AM and Noon.
Bob Cleary
THE BEST!!
THE BEST!! We've been relying on Guarini Plumbing for I don't know how many years. They've been consistently competent, knowledgeable, efficient, fair, and friendly. Would not even consider calling anyone else for our plumbing needs.

Overall Positive Experience
I recently had my gas water heater replaced through PSE&G and they sent Guarini Plumbing to do the work. I had an overall positive experience and would definitely recommend this company.
They showed up on the scheduled date/time and the price I was quoted was what I was charged. They had to replace an additional pipe that connects to the chimney (which cost me an extra $200+), but another company had also informed I would need to do that so I was ok with it. The installation guys were friendly and the work was completed in less than an hour.
A few hours later I noticed some dripping from the pipe attached to the relief valve which stopped on its own. The next morning I noticed some additional drips and since I didn't know that was normal I contacted Guarini and they scheduled someone to come between 1 p.m. and 4 p.m. the same day. At 4:30 p.m. no one had shown up so I called them once again and later the same evening 2 different guys showed up. They checked and stated that things were good. They replaced the pipe with a longer one pointing directly in the drain pain (which should have been done initially. The old pipe was short and was dripping outside the pan).
Since then things have been ok, I've been monitoring daily and I don't see additional dripping. In summary, there are some things that can be improved but overall I was happy with the work.
Renato Miranda

Always on time!
I am immensely grateful for all the people that have worked in my house. They are thorough, friendly, helpful, informative, and above all knowledgeable of what they are doing. They have offered suggestions in making things better in my home. They do their job to perfection and clean up after themselves. It is a pleasure watching how they do their job. I must say I learned a lot from them. They are always on time! I will not hesitate to contact them in the future.
Julie Hernandez
Extremely Impressed by Their Professionalism
I recently had extensive plumbing work done by Guarini Plumbing, which involved excavating 10 to 12 feet on my property. I was extremely impressed by their professionalism and care throughout the entire process. The team was efficient, detail-oriented, and ensured minimal disruption to my family. They maintained a clean and safe work environment, and I couldn't be happier with the results. I highly recommend them for any plumbing needs. Thank you for your excellent service!

Professional and Licensed Service
I was issued a red tag violation from PSEG. I contacted Guarni Plumbing, and they scheduled me for the following day. They resolved my issue. They are professional, licensed, and insured.
Salvatore Brancato
Incredibly thorough estimate
We want to replace our HWH and called PSEG, and they connected us with Guarini to provide the estimate/installation. Diego came promptly on 1/30/24 to provide a more detailed estimate, and he was incredibly thorough (testing water pressure and checking chimney venting). He provided info in laymen terms and handed me the written estimate. A different company provided a ballpark estimate on 1/29 but didn't do those tests, so we didn't have an accurate idea of the estimate add-ons that they would've stumbled upon. I'm reaching out to Guarini for a revised estimate to change from gas to electric HWH. I like that they have qualified staff on the phone, scheduling, etc. Very happy with Guarini customer service.
Cindi McLoughlin

Outstanding Service Today!
Shout out to Guarini Plumbing for the outstanding service I received today! I called this morning to have our heater serviced and the lovely Janet Siguenza got back to me right away. I was able to schedule an appointment for this afternoon and received a confirmation email immediately. I also got a call to let me know that the crew was on their way (on time!), they were professional and friendly, and did a great job. And the price was reasonable. I highly recommend Guarini Plumbing!
Susan Mc Laughlin
A highly recommended team!
My water heater conked out on July 3rd (I guess it wanted its independence early). I contacted PSE&G Worryfree and we scheduled my replacement for July 5th with Guarini Plumbing & Heating. The two technicians, Filipe and Fernando, arrived on time. They assessed the situation and explained what needed to be done to bring the gas, vent, and water connections up to code. Around an hour and a half or so they had completed their work. Filipe and Fernando were polite, cleaned as they worked, and answered all my questions. A highly recommended team! Thanks guys.
Rich K
Excellent service with kindness
If you want an honest, professional plumber who knows what he’s doing, call Guarini Plumbing! Steven M. came and not only fixed my issue but also pointed out something else that needed to be fixed and helped prevent something catastrophic from happening! Excellent service with such kindness and professionalism with that old-school personable touch! I give Guarini 5 stars all the way!
Ani Kay
Highly recommend this company
We’re very professional, especially after a long day. They finished at 10 p.m. and had to work 7 a.m. the next day. We now have hot water, which is all we needed. Would highly recommend this company.
stanley osur
Strongly recommend this family-owned company
I recently had my water heater replaced by this company. By the way, this is my third time using them for a water heater replacement. My installers for the day were Ervin and Jeff. These guys were professional, and they worked together as a team and did an excellent job. They completed the job in a timely manner and moved on to their next appointment. I initially asked a lot of questions before scheduling the appointment. The reason for all the questions is because it had been a number of years since I needed a water heater replaced. I have to admit that I was pleasantly surprised to see the quality of work hadn't changed throughout all the years with the company. Therefore, I have to strongly recommend this family-owned company to anyone requiring their services. This is for the business Guarini Plumbing.
