Hired Guarini through PSE&G and they were extremely professional, accommodating, and friendly to work with. I didn't think the hot water heater they installed got the water temp hot enough long enough so they came back and raised it a bit and it's perfect now.. thank you Steve and the Guarini team!

Guarini Plumbing installed over 150 safety valves in my mid-rise building putting an end to our constant flooding fears due to failed water heater leakage. They were easy to work with and were more than 90% reliable with appointments.

They offer my residents excellent pricing on water heater replacements and install quickly.

When faced with trying to find a plumber, there is usually some urgency. When I was offered Guarini plumbing's contact info on a recommendation from a friend, I had high expectations. To say their performance, professionalism and personality exceeded my expectations is a welcome surprise. Laurie, Rachel, and the whole team here is fantastic to work with. I highly recommend them and their company for anyone looking for a trust-worthy, high-performing plumber that also happen to be amazing people. Thank you!

The plumber never showed up to his appointment. We called the office and they said that the plumber will come later in the day. Never showed up and nobody apologized. This was just before a long week-end when we could not call any other plumber.

Zero for trust
zero for customer service
zero for courtesy.

Predator Company charged me for nothing. Charged a fee of $264.52 to come out and look at my furnace after it stop working after I had a water heater replaced by PSEG. I thought water may have mixed with my oil I called the company back out to find out what was going on. This is the only number I had on the invoice thinking this would be apart of the Job done by PSEG it was not. The guy goes down stairs in my basement looks at my water heater, next furnace then tells me I need oil. Did absolutely nothing then charged a fee of $264.52. When I ask to speak to his supervisor he told me that his supervisor would not answer the phone. SCAM I will never call them again anything especially if it has anything to do with a PSEG issue! They should let you know in advance that you will be charged outside of PSEG agreement!

After a frustrating morning from a condescending PSEG guy. I called PSEG and they recommended Guarini to replace my water heater. They guys (Dave and Erwin) arrived within 30 mins. Very professional and they explained everything to me. Never once talked down to me like Vinny from PSEG did this morning. Thank you guys for replacing my water heater and doing a good job at it!

I was told there would be a refund for the boiler I choose. I sent the paperwork in but was denied by .01 environmental score. I contacted them 2 times, no reply. Don't believe what this company tells you. Get it in writing.

Would use them again and would recommend them to others.

Used them twice. Good service, excellent work.

They were assigned to me as contractors from PSE&G to replace my hot water heater. First of all...they showed up on Sunday morning which was AMAZING. I was not expecting to have hot water back within 18 hours of my tank busting. They were fast (it took them about 2 hrs). They explained the process to me, showed me how to work the new tank and tidied up after they were done. Courteous too.

Very, very pleased with the service I received today. The faucet in my shower stopped working last night (the handle turned and turned but no water came out). I called several plumbers beginning at 8:00 am this morning. Guarini Plumbing answered my call and the receptionist was professional and pleasant. She explained the rates to me and spoke to a supervisor to see if they could fit me in today. I was told a plumber could be here between 9:00. am and noon, so I took the appointment. The plumber called my cell phone at 9:45 to confirm my address and let me know that he would be here in about half an hour. The two plumbers who came to my house were pleasant and professional. They quickly figured out what was wrong with my faucet, turned off the water in my building, got the part from their truck, got the faucet reassembled and working and the water back on within 35 minutes of arriving. They charged exactly what I was told they would charge when I called this morning. I will not hesitate to use them again and will recommend them to my friends and neighbors.
