This company secured a major contract from Jersey City to upgrade several water supply lines from led based pipes. This project has been ongoing for the better part of 2 years. They have carried out this project with the finesse and expediency of a hobbled monkey pulling a cart of other hobbled monkeys. The Mario brothers could have done this and saved the princess in half the time. I have never in my life seen such a display of inability in my life. Over the last year, they have been working on the same 6 foot span of plumbing in front of one of the public schools. They have trenched up, filled, trenched again, filled, trenched again, filled, the EXACT SAME SPOT on the street. This is either complete incompetence, or a racket of some sort.

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.

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 1pm and 4pm the same day. At 4:30pm 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.

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.

We've had Guarini do a few jobs over the years, mostly on short notice: two water heaters, and repair of a steam radiator boiler system. Every time I've called them I've been honestly surprised by how fast they show up (usually the same day!). Price has always been as good or cheaper than the quotes I've received from other plumbers. A couple of times when we've had issues after repairs due to our ancient 120 year old house, they've done a followup fix with no cost to us. Each time they've walked us through the issues we're facing and what parts they're replacing, never once pressured us into more costly repairs. I really do appreciate the work you guys have done for us.

Two workers came to replace my water heater, and with the light of the cellular phone they took a look at the chimney and I was told how lucky I was that the water heater broke because the chimney needed repair, and CO2 fumes were backing into the house. I was told they could install metal pipes into the chimney for about $3,000. I agreed to it for my family’s safety. An appointment was scheduled for two days later at 9:00 am. I didn’t go to work on that day. Since they hadn’t come by 10:00 am on the scheduled day, I called the office only to be told “I’m sorry, we forgot to put you down on our schedule”.Very irresponsible on whoever does the scheduling. I missed a day’s work for nothing. 😡

Complete ripoff of a company. billed my HOA 3 hours at $325 / hour for "leak investigation" which they billed to me. Will never use this company and will tell everyone they are stealing from people and terrible
