Sideris Plumbing & Heating

Jerrianne H.

The Sideris professionals did a fine job for us. They had done a job in one apartment of our building installing a thermostat for controlling the apartment's heat and we liked what they did on this small job We had a main gas line shut off by Con Ed which is a big deal. Sideris responded to us faster than the other 2 companies. They inspected the problem and gave us an estimate at no charge. Another company said they would not give an estimate without our paying for their time. Sideris found the gas leaks and made the repairs in a straightforward and due diligent manner. I was a contact person and I watched how consistently they performed troubleshooting in each apartment and in our boiler areas. They gave us information in timely fashion and solved the problem and navigated through the bramble of Department of Buildings and Con Ed inspection processes that can take forever if you pick the wrong plumber. I am very satisfied with the quality of the work and the competence of the people they sent in timely fashion to get our gas restored.

Good but a caveat in the review on their electrician!

Got work done with them in 2017. Wanted to get a NEST thermostat installed on a hot water radiator heat line. They did a fantastic job and were thorough to know what needed to be done.

I wasn't a big fan of the electrician they worked with though. He made an extra hole (cause he needed to run a line from the thermostat to the valve) and didn't patch them up. I had to get another contractor to fix those.

Sideris Plumbing & Heating is a great company. They are experts in their field and are professional. I was having issues with my heating system last winter and wanted to get it checked out now during the summer months. I was referred to the company by a friend to call. I spoke with John the owner and he came over to give an estimate and see the job. My heating system was very outdated and he recommended to replace both the boiler and water heater. He gave me a price and assured me that his company knows how to do the job right, I will have peace of mind and be warm in the winter. They sent Richie, a very knowledgeable and kind technician to do the job. They finished the job quickly and the work looks great. Will definitely call again!

Don't waste your time, especially for smaller jobs.
I had two small, simple jobs, and was told they could do them, and they'd be there the next day, between 9 and 12. When they hadn't shown at 11:50, I called. Was told they were ""on their way to me from the last job and should be there any minute."" At 3:00, they still hadn't shown. I called again. ""They apologize; they couldn't come in today,"" whatever that means, ""but they can definitely do the job, and will give you a call this evening or tomorrow morning."" By the next afternoon there was still no communication from them. At 3:00 I received an EMAIL stating they apologize, but can't take the job. No reason was given. In my humble opinion, this is INEXCUSABLE behavior for any business.
Go with Sanitary Plumbing & Heating Corporation; they were extremely professional, prompt, and polite.

Ten years ago I would have recommended them, even though they are far more expensive than other plumbers I use. But they seem to be in way over their heads on new technology. They installed very expensive new boiler, didn't quite finish (despite being paid in full) and there have been problems every year with it since. Also, their work has gotten quite sloppy over the last few years.

i called and got my info taken, within an hour I got a call back with an appt for the next morning. Plumber came early, did excellent work, cleaned up and was gone in an hour - for 2 toilets. competent, capable, and responsible. what more could you want.

As the other reviewer mentioned, this company doesn't offer a free estimate. They charge a flat fee to stop by and assess what you need done then quote a price.

The only problem with this system is that they can quote you ANYTHING, and you're still on the hook for the service fee, no matter what. This is problematic, because they can quote you a very high, non competitive price, knowing you will not accept and then still pocket the fee.

In the end I didn't contract them for the job, so I can't comment on the work and I'm not saying this sort of thing will definitely happen, but I thought I'd point out the potential pitfalls to others. Caveat emptor.

I called these guys because of an emergency situation in my bathroom. Within an hour, a plumber showed up. But instead of going to work on the pipes no-questions-asked, which would have left me with a hefty bill, he evaluated the problem as one that should be dealt with by my apartment building superintendent. He estimated that it could cost as much as $800 to fix the problem and suggested that I get the super to hire someone to do it, thus saving me money. The visit and consultation were completely free. Two thumbs up for integrity!

I would give this company a 4 or 5 if they were not so expensive. A relatively straightforward emergency job was a lot more expensive than expected.
In saying that, the company was very responsive and the plumber that was dispatched was helpful, fast, communicative and professional.
