Gramman Plumbing & Heating Corp

After getting 3 bids from plumbing companies we chose Gramman Plumbing to install our Burnham Gas Boiler in November 2015. We are very pleased with their work!

Our previous Burnham boiler, installed by a different company in 2005 (one that was recommended) was done incorrectly and completely failed. No, Gramman was not the cheapest nor the most expensive - BUT, you do get what you pay for. NEITHER of the other competitive bids included installing the air induction by a licensed electrician (required by Nassau County) and DID NOT include obtaining a permit, inspection & approval for a C.O. from the Town of North Hempstead. Gramman took care of everything and was on site during the inspection. The plumbers' work is professional, neat & clean and after a year and a 1/2 our boiler still purrs like a kitten. Our pipes no longer knock and we barely know it's on. The office staff couldn't be nicer and they're a pleasure to deal with. We have hired Gramman for subsequent jobs and would definitely use them in the future. Their work is spot on. P.S. and yes, we do have the service plan, which is nominal compared to a total replacement.

Bobby, Pat, Nick and the rest of the team did a fabulous job changing our heating system and installing new Runtal baseboard. They are expensive, but you get what you pay for. I had excellent communication and planning by the entire team. The office would call me every day to ensure that I was aware when technicians were coming. Bobby stopped by the house at least 3-4 times a week to ensure the team was executing to his exact standards. I couldn't have asked for a more professional and polished team. Gramman has a new customer for life.

Needed a plumber with a local village license for the co-op my son lives in, so my plumber gave me their name & number. He told me they were very good but I would pay a premium for their service. The girls in the office were very courteous and got the paperwork necessary for our management office then scheduled an appointment for the next day. They were on time and explained the options available to my son and did the work to repair the problem. I was very happy with their service and will definitely use them for plumbing work in the co-op if needed.

Hired Gramman to do my home gas conversion and install a new condensing boiler. Their quote and others were similar but I chose them because they took the time to really go over my options, as I was involved in the oil service industry and know the business. They were professional, showed up exactly when they said they would and did an incredibly neat job - and they minimized downtime doing the job mid-winter. There were no surprises and I have realized a fuel cost savings which was on target with their estimates. They run a tight ship and the customer benefits from their diligence. Highly recommended.

I highly recommend Gramman.

Bobby (owner) and his team are professional, punctual, friendly, clean and courteous.

We have worked with Bobby on a few jobs and everything has worked out great.

Five Stars is not enough for Bobby and his staff at Gramman Plumbing and Heating. We recently converted from oil to gas and Gramman was recommended by our good friends at Handyman Express (which also gets an A+, by the way!) The team that Gramman sent out, led by Rob--and his guys Mike and Mark--were professional in every sense of the word. They were respectful of my home and my family, and took the time to answer every single question I had about the installation process (and I had a lot of questions). They made sure everything went smoothly and I cannot speak highly enough about the entire team. And, of course, the heart and soul of Gramman--Roe back in the office. I can confidently say Gramman more than earned an A+ in my eyes.

We've used Gramman twice for work in our house and each time have been very impressed.

The first time we called them, we had a hot water circulator pump that had burned out. They came by within 15 minutes of calling, and before coming out, were very up front about the diagnostic fee (which they charge if they don't do any follow-up work, but credited back to us when we had them do the repair work). Long story short, the previous owner had tried to do the work on the cheap using one pump and it was not sized correctly. Gramman put all new circulator pumps in, and Bobby came out twice during the day to make sure everything was being performed up to their standard for workmanship.

The second time was to install a gas fireplace in our house. Not only did Bobby come out personally to estimate the work, but he also has helped us through the entire permitting process, was able to recommend a reasonably priced architect for us (since our town is being ""difficult""), and even dropped off the permit application himself. The work is always done on time, for the amount that's quoted, and they are up front with regards to the service plans. If you're having work done and signing up for a service plan will make the whole project less expensive, they write that all up for you. They let you change plans when they come up for renewal without charging the new plan fee, and are just very upfront and honest about things.

Bobby and the team from the office are all great to deal with, and we've had nothing but good experiences.

This company does not deserve any star at all.

For all typical working family out there, I wish I had read the reviews of this company before I made the appointment. Now it is too late.

Look out ! This company has hidden Service Call Charge of $149 + tax = $161.85.




They will not tell you ahead of time over the phone when you make appointment or inquire about the price estimates.

They will tell you wait for the repair man show up and talk about the pricing details.

When repair man shows up, selling the membership is top priority, when all things fail, they will then charge you with the hidden Service Call Charge.

Absurdly overpriced-at least for smaller/residential work. I called them for very simplistic work (cap gas line and repair leaky dishwasher hose). The rather unexperienced plumber sat there like he was writting a disertation. Then, after ~15 minutes, he gave me the quote of $1,300! Ha! Then he had the nerve to ask for an 'estimate fee'. They should be ashamed of themselves--going around quoting 4 times the market rate so they can steal that $150 from hard working folks. I got another licensed plumber that did an exceptional job for $200! For everything.

Fabio G.

Just called them and can indeed confirm: it's $150 just for the technician to come over your house and look at the boiler.
The technician will then say what's needed to repair/service the boiler and, if you agree with his plan, the $150 fee is then waived.
Sounds like a bad business model to me, wouldn't recommend to anyone.
