William J. Guarini, Inc.

This company is the best for difficult plumbing issues. They are highly experienced and get the job done right the first time. I highly recommend them for all your plumbing needs.

An great experience. Very helpful on the phone to book an appointment. They arrived quickly, got everything done and were professional. Would definitely use them again.

Great service, a pleasure to work with!

Very professional. On time. Explained everything and addressed my concerns. Ensured safe installation and was very quick and clean. Beyond satisfied. Thank you William and Bryan!

Guys are courteous and do a great job

very professional.

Supervise them every moment of their service, otherwise they just leave you with damages and lots of work.
They left my house with a lot of dirt, not responsible to clean up. The worse part was when they were taking up the old water heater up from the stairs, they broke my stairs and when I told them, they offered me a ridiculous amount which was like insulting us and asked me to claim to PSEG which they already knew they don't take the responsibility either. I trusted PSEG that is supervising these companies!

Highly professional company with excellent employees - Freddie & Roy did flawless work!

Replaced water heater through Pseg. On tIme and work completed to my satisfaction. Recommended.

Perhaps they are a fine plumbing business but that is not the experience we had. Our issues could have been avoided with better communication from operations. A commercial plumbing project was scheduled with Guarini but 2 days before project start, they canceled citing schedule and budgetary issues despite no changes in details. We have parted ways.

Use this company for our condo association. Very happy with them. They came early both times I needed their services and were quick and professional. The plumbers were nice guys both times. I will use again.

Great service, quick responses, job well done

We’re very professional, especially after a long day. They finished at 10 pm and had to work 7 am the next day. We now have hot water which is all we needed. Would highly recommend this company

Guarini Inc is doing work on a one block stretch of Magnolia Ave. They are replacing the water and sewer mains and replacing each home's water and sewer line from the curb. The crew is nice and when some water was leaking into my basement they quickly found and fixed it. I am grateful for the new lines being replaced at no cost to the homeowners. My only complaint (and knowing that Rome wasn't built in a day) is that they have been at it for 4 months with no end in sight. It is very disruptive to the neighborhood. I don't understand this. Are they being paid per diem?

A great professional service company from beginning with the first call to the end of their quality job, another happy customer here!

I have hired them twice for leaking and toilet issues. I like they are transparency about pricing. It is charged per hour. The staff arrive on time, efficient and very professional.

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 change throughout all the years with the company. Therefore, I have to strongly recommend this family owned company to anyone requiring their services.

I recommend Guarini Plumbing very highly for all your plumbing needs. I have worked with these folks for 20 years on jobs that include indoor plumbing repairs, jetting and snaking drain lines, and outdoor excavation for water and sewage lines. The staff in the office is courteous and accommodating and communication is very good. Their plumbers, excavators and helpers are all very professional, polite and conscientious. If you need any type of plumbing work, I'd suggest that you give these guys a call.

Excellent experience! They are true professionals, and sensitive to my needs. Great value!!

The two plumbers who visited, Roy and Peter, were first-rate in diagnosing three separate issues affecting the shower, and they also insulated my hot water heater with an insulation kit that I had previously ordered from Amazon and swapped out the whole-house pressure pump filter for me, as well turning on outdoor faucet fixtures for the season and letting me know what I needed to do to fix a leak in one of the connections.

The only reason this review is three stars and not five is because Guarini Plumbing charges for non-existent time that they do not actually spend on your job. They do let you know when you schedule that the cost will be $200 per hour, but what they never tell you upfront is that even if you have a half hour of time beyond that hour, they will charge you for another full hour, not the actual half an hour. So I was billed $400 for two hours, even though the two plumbers only spent an hour and a half at my residence.

To avoid this from happening to you, either insist on only being billed for time actually spent on your project upfront, not rounded up ... or if they are adamant about not changing what I consider to be an unethical policy and overlooking communication about it when scheduling, at least have 1-2 optional smaller maintenance jobs ready that Guarini plumbers can do for you with that remaining half hour, so at least you are getting your money's worth for your considerable investment.

They were so organized, efficient and knowledgeable. They explained everything thoroughly. Worked cleaning and brought us up to code with the new installation of our new water heater. They are pros in every sense of the word, and we are so very grateful for their help and service. Thank you!

The guys from William j Guarini plumbing they did the job fast and with profession👍👍

Excellent service
Knowledgeable staff

I have been using Guarini plumbing for years ever since I moved to Jersey City. I just had an appointment with Freddy. He fixed our leaky toilet and replaced a broken faucet. He is great, fast, and friendly. Highly Recommended.

Always solve every problem. Very knowledgeable people.

Set up service for a hot water heater replacement thru PSEG. Was ultimately assigned to Guarini for service. The technician arrived within the prescribed time frame, but all went downhill from there. They did not go to the basement door as requested, when no one answered at the main door, the technicians left without even a phone call. Main office called me a few minutes later. I clarified to please go to the ‘basement door’. She stated that ‘they are there now’ and no one is home..My tenant who who was present at the address was on the other line with me and standing outside the residence. I asked the dispatcher to describe the vehicle so my tenant may assist in locating them. At this point, she told me they’re on there way back!?! 10 minutes later they arrive and contact me saying they have a 40 gallon on the truck that would fit perfect (I ordered a 50 gallon). I had no choice but to accept the 40 gallon as my home was without hot water. 20 minutes later I received another phone call telling me it is necessary to replace my chimney lining at a cost of $2400. I agreed to the repair and inquired when will the job be completed. I was told they can only do the hot water heater today, get it up and running and someone will call me tomorrow about the chimney. They then demanded full payment for both the hot water heater and the chimney. I informed them that I would not pay for services that are not going to be rendered, nor complete. The chimney work wasn’t even scheduled! I offered to pay in full for the services being completed that day (installation of the hot water heater) after the chimney work was scheduled I would pay in full then. I asked to speak to a supervisor at least 4 times between 4:45 and 5:15 and was told ‘no’ or that they would call him each time. At no point was I able to speak to a supervisor. I was not comfortable paying for services not rendered nor scheduled with a company that I have never done business with. The technicians left without completing the installation of the hot water heater, leaving the home devoid of hot water with a family a young child resident. After they left my tenant called to inform me that both technicians present seemed disinterested and unprofessional. They made him uncomfortable and he expressed concern about having them come back. I dispatched another company to complete emergency repairs shortly thereafter. I own multiple properties in multiple states and never have experienced difficulty in this manner. The way this was handled was tremendously disappointing. I have never nor would expect to pay in full for a service not even scheduled. How long was I going to wait for this additional $2400 repair?....how long would it take?....When would it be complete? I receive absolutely NO answers to my questions, was told to pay in full and someone will call you tomorrow with answers. Unacceptable by any standard. Bad business practices, use caution dealing with this vendor.

Great experience with Guarini! Linda in the office was responsive and had me scheduled right away for an estimate with Mike, who sent me the pricing a few hours after coming. The plumber, TJ, was extremely professional and kind. The job came out perfect! Everyone was great to work with. Will definitely use their services in the future!!

Really top notch service! I own a home in jersey city and unfortunately had a lead water line and a collapsed clay tile sewer line. This was a big job considering the sewer line was 10 ft. deep. I got a few quotes from some other plumbing companies and they were mostly around the same price; some were very high though. But after speaking to Bill Oriani in the office and having him walk the job I was confident he can get the job done.

Rachel in the office took care of all the scheduling and permit setup! Kudos to her as she had to deal with the historic department, building department, and traffic control. Living in JC; trust me that is no easy task!

Guarini completed the job in 1.5 days and explained and showed everything to me every step of the way. Overall great service and fair price for job that was done! Thank you Bill O. and Rachel!

March 8 will had the 1st floor bathroom shower plate develop a leak and potential basement apt damage. Technicians Fred and T.J. arrived early, using CoVid-19 protocols and safety. They worked out a method where they did not need to break any wall or shower enclosure. This saved time and money. They replaced a 30 yr old Moen system will a diverter plate and newer Delta system, with updated code specs. Fred and T.J. were done in about 2 hours time, leaving the bathroom clean and usable. Job well done.

The best plumbing service for over 40 years that we been using them.

The service was great very professional. Rachael was very good. She following up and was very pleasant to work with.

They are professional and they know what they are doing.

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!

Needed an emergency water heater replacement and was very pleased with the service provided by this company. We noticed the leak around 5:30am, was on the phone with this company at 7:30am and had a newly installed water heater by noon. Ervin & Luis came to my home and were extremely respectful, professional and efficient. They patiently answered every question and made suggestions for avoiding a similar disaster. We will definitely use this company again.

Fast response to problems good people

The QUALITY goes in before the name goes on! I recommend GUARINI any time! Their prices are Steep. However, they stand behind their work...💯

I just want to say that guarini Plumbing is the best !! From the office staff to the guys out in the field they get the work done ASAP the prices are very fair and the guys on the field are gentlemen

I will never use the plumber again, the job was overly priced and I still have a leak in my home.

Have used Guarini numerous times. The employees have always been courteous, knowledgeable and professional.

William J. Guarding is hands down the best plumbing service my family has used. The amount of knowledge they possess is bar none. The quality of their work is unmatched. Freddy has been servicing my family for years—the confidence in his work and quality of his work is phenomenal. He is extremely professional, and jovial, cleans up after he is done, and makes the entire process so smooth. Not to mention he is always on time!!! Please request Freddy for your next appointment. Thanks so much for help Guarini

Service was awesome. We had a water heater repaired and the team that did the work was polite and very skilled. They did the job quickly and cleaned up when they were done. I definitely recommend and would use them again.

Efficient and Reliable. Staff is excellent and they take steps to keep your home clean while they work. No surprise pricing and they do CondoApartment work with COA also.

I had them replace my water heater. They showed up almost on time, were super courteous, and the job quality was great. The negatives - they were many hundreds of dollars over what others charge, and they pushed hard for installing an electric component that was not required per code in my home (later confirmed by the municipal inspection).

Roy and Nick, two of the plumbers from Guarini, were able to come a day earlier than expected to fix a gas leak. They were both professional, courteous and overall nice guys. Reasonable prices too. Would absolutely use their services again!

Great service, arrived on time and fixed water leak in our home quickly. Highly recommended!

Walking my Dog as I have done for years around the block , I came across this Juanta company who closed the road on South Street between New York and Pallasades Aves, besides the gentleman who showed me the permit, the Guarini crew were intimidating, belligerent and acting like entitled fascists, something we're all too familiar with these days. Unbelievable in my own neighborhood, thanks FULLOP for giving our tax payers money to your pals

Mike and his team came in to do an assessment on flooding we were experiencing inside of our home due to recent heavy rains/storms.

He and his team flushed the pipes to the sewer, and then installed mechanisms which would prevent flooding from being a recurring issue for us in the future.

The entire team at Guarini did excellent work. Kudos especially deserved to Linda & Carleen on the administrative staff for their integral roles in expediting resolution for us.

I live on the street in Jersey City where these guys are working for the past 2 months and believe me they have no idea what they’re doing. They have ruined the whole street, they have dug the whole street I think more than three times because they just don’t know how to fix things the first time. Causing a hell lot of trouble for the residents of the street with dust and noise all day. Now after two months when we finally thought they have completed the job because they completed the road, they dig it again cause guess what, they messed up again! Would highly recommend the city not to work with this company again.

Had a luke-warm at best shower, was quoted from others it would cost up to $1,500 to replace the entire system. Roy & Nick instead went with a much simpler solution, did some manual work, and fixed the issue for $200. Going forward will use them for everything water related.

With the work they do, you wonder why its so hard to find a place to get the job done. All their employees you can see are really like family. They took care of me like I would anyone. Any plumbing needs will always be done thru them

Paid 1431 and leaked again hours after it was done. Most likely More money again to fix it again (when it was never fixed in the first place) The leak should stop when you hire a plumber to fix a leak after you pay so much money.

Should not have offered to do a job for that kind of money if you cannot fix and take the money and leave someone in the same spot they were in before they called you. So we’re out 1400 and still with The same problem. So disappointed.

Great Service and Project Management. Thanks Rachel & Billy and the entire team for a job well done!

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 from something catastrophic happening ! Excellent service with such kindness and professionalism with that old school personable touch ! I give Guarini 5 Stars all the way !

Great company ! Always on time , very professional !
Definitely recommending !

great work, courteous and kind. Thank you, Robert!

Please advise your employees that when they cut through a parking lot to avoid a stop sign in an attempt to get 1 car further ahead in traffic that they should at least wave sorry/thank you to the driver of the other vehicle they almost collided with.

Replaced the gas hot water heater. Both technicians were very professional. The best

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.

Mike came over. Explained my options and gave me estimate. Once parts arrived guys did the job. Very quick. Exactly as it was explained. Then they did two more minor jobs. Same experience. Exactly what I expect of professionals!

Even though it is understood that prices would hike during a recession, these prices were outrageous and service was VERY RUDE.
