Of course, on Sunday our heat and hot water stopped working. We contacted Gramman Plumbing, explained our situation and requested to have a technician come and diagnose our problem. The young lady we spoke to on the phone, I believe her name was Johanna, was extremely polite and understanding. She explained that she would send someone over as soon as they can, since they were very busy due to multiple house calls. And no sooner then I hung up, probably 20-30 minutes ;), Mr. Bobby Gramman was at our door! He was very polite and extremely neat. Mr. Gramman rectified both our issues. I would highly recommend Gramman Plumbing! Courteous, Professional, Respectful.

Estimates were ridiculously high. $500 for toilet and $700 to replace kitchen faucet. I paid the 150+ tax for the estimate and sent guy away. Ordered toilet part for $15 online and replaced myself in 15 minutes. Called faucet company and they replacement cartridge for faucet no charge and I replaced it myself also about 15 minutes. Never using them again.

Excellent, for the second time. Very clean, punctual and professional. Very clear about what gets done for how much money though they a very complex pricing scheme. Overall it seemed to be about the right price. But I'm not quibbling because I have complete faith in their work.

If you need any steam heat work done, Gramman is your company.   Bobby and crew completely understand the intricacies of steam heating.  There are few people that truly get it. (After all, the last home steam heating system was installed over 60 years ago).   Bobby has a copy of the book "The Lost Art of Steam Heating" and seems to have memorized it. 

Their knowledge was quite welcome because, just 6 months prior, I had this boiler replaced by a plumber who didn't have a clue about steam heating and what a disaster that was!  For starters, he put in a boiler that was too small for the house. And it went downhill from there.  The shoddiness of his work and the quality of Gramman's would be apparent even to somebody with zero knowledge of plumbing.

They keep their appointments, are super clean (floors covered, cleanup done).

The down side is the pricing.   I think the overall price was ballpark, but they have this weird "plan" where you pay $460 for one year's worth of a 25% discount on all charges plus you get one boiler cleaning.  So if I didn't get the plan the charge for the installation would have been ridiculously high (and I would have used another plumber).  I guess the idea is to encourage you to call them again.   But if seems that they start high and the plan just brings it down to normal.  Also, they charge for estimates.  This charge is later refunded if you have them do the work.

The charge for the backflow test was about $300 for 10 minutes of work.  Other plumbers do it for $75, I later discovered.

They were very professional and courteous from the get go. They were EXCEPTIONALLY clean. They lined all flooring with protective coverings, they used plastic tarps when needed to block dust and they wore booties every time they entered the house. The crew was great and the work was well done. When there were few things that that needed to be tweaked, they came back in a timely manner. Also, since the was a major overhaul, I had to relay the message between them and my husband and they didn?t have a problem dealing with woman, as many plumbers I have dealt with the pass had. I can't give them an A because-- I wanted a service contract on the system, and they don?t offer service contract (which was not clearly explained when we made the purchase). They offer some book of service that you buy in different dollar ranges. It covers all plumbing, not just furnace. So in order to cover the furnace I would need to purchase the gold book of service which didn't really cover general maintenance for furnace for approximately $1,000 per year. In essence, I am buying plumbing service I would never really use. Very bizarre pricing structure. We were told by the son of the owner that was there new way of doing things. In any event, we did ask on two occasions to send us material on the pricing book and service and never received the infamous pricing book.

I think this company over charged us and we would never ever use them again. They deserve all F's because I thought they were incompetent. I mean, if they had done the job right the first time they would have saved themselves and us a huge headache. That is my opinion on this company. I for one will not use them again. I do not hire companies to only complete half the job. I do not give them only half of the money that they request, so I expect good services. I just didn't feel like I got that with these guys, so that's pretty much why I would not use them again.

When they left, the sink started making horrible growling noises. I called them to come back and fix it and the secretary was very rude to me. She told me that I did not know what I was talking about. That upset me very much. Therefore, I wrote a letter and told them that I am not going to be a customer any more and that they need to follow-up with their customers and have more professional secretaries.

I WAS PLEASED WITH THE SERVICE I RECEIVED FROM THIS COMPANY AND THE PLUMBER THAT COMPLETED THE WORK. THE PLUMBER COMPLETED THE JOB IN A TIMELY MANNER. I HAVE NOT HAD ANY PROBLEMS WITH MY TOILET.
