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.

When it comes to boiler replacement the Sideris Plumbing & Heating company is the best! They were more than competitive with price, very efficient in their work and overall great professionals.

I'm not sure what the other reviewers mean about a charge for their quotes since i was not charged a fee for my estimate. John and his team were great and I will definitely be calling on them again for any future work!

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.

Work done was shoddy for supposed professionals. Took much longer to have service turned back on than should have been and the bill was much higher than quoted. Not Honest! Terrible lies were told.
I will never use them again an would suggest that potential customers find a more reputable company.
There are more reputable companies available. Research!!

Effective Sideris Plumbing is the best plumber in New York. I first met their plumber Sergio Siles when he fixed a leak under my sink in minutes, after it had been misdiagnosed by at least 3 different plumbing teams. Since then, their plumbers have snaked a drain and even done major work within the walls, all with perfect professionalism, excellence, and long-term sustainability. I would never call anyone else.

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.

They came and supposed to have to find leak. but did not, and also we hire them for 2 jobs, both of them they failed to follow the specs. When we question them, they said they don't have to follow the specs. We had a main gas line shut off by Con Ed, they did not help us restore the line that has leak, only restore the line that has no leak to start with. And it also takes much longer than necessary to file our document for inspection, & also after inspection and to turn our gas back on. On top of all these, they are also more expensive than other plumbers.

These guys answered the phone right away and called back within 10 minutes with a time they could stop by. The reason I gave them an average rating and why I didn't go with them... $185 minimum service charge, basically no free estimate offered here.

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.

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.

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.

John Sideris Plumbing is one of the most professional organizations I've ever dealt with. The owner is passionate about providing top quality service and the guys he sent to the work were friendly, clean and professional.

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.

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!

my garbage disposal was clogged and nasty water started backing up during the weekend and when i called John, he called back within half an hour and asked if i needed him to check on it immediately
i told him the next day would be ok and he came at the time he said he would, looked at it and explained to me what was wrong with it
he also gave me tips on maintenance, what's more he fixed my toilet when he was here too

John is professional, funny and charges a fair price
I highly recommend him
