William J. Guarini Inc.

I used Guarini for the repair of a leaking water service line. This is not an average plumbing job. It's a minimum 8 hour job, with a team of four or five people. I chose them because they got recommended by several other plumbers I spoke with. And they did a great job. Price was fair, more affordable than two other quotes I got. Their people are very professional and pleasant to work with.

I found Guarini Plumbing after getting an absurd quote from Roto-Rooter for a broken sewer pipe. Guarini was far more affordable and a huge relief to work with. It was great to deal with real people who were honest and straightforward the entire time. The job took just slightly longer than estimated, and they did not overcharge for the extra time… something that’s rare in plumbing work. Huge shout-out to Rachel, who was helpful and communicative from the first call through completion, even around the holidays. The crew doing the excavation and pipe work was professional, respectful, and genuinely considerate. They even delayed towing a car parked in a blocked-off area until it was absolutely necessary, which says a lot about how they operate. Excellent plumbing and sewer repair experien

I have called on this company so many times knowing I was dealing with good honest professionals. I’ve had several plumbing and heating problems. They always came through for me. I trust their judgement and work….and their prices were affordable. They have 24 hr service and can always be reached at any time! Great office personnel, too.

Reliable and professional. This was my first time dealing with Guarini plumbing. They were quick to respond to my plumbing problem. The plumber they sent out, Dominic, did an excellent job. Very good people to deal with.

Received a new hot water heater through PSEG replacement program. Plumbers from William J Guarini showed up on time and explained everything. I needed an expansion valve due to high water pressure and they installed that as well. They took the time to cover my steps and cleaned up when finished. I am very satisfied with the job.
