Verified record
Nelson Gagnon Plumbing Heating is a Beverly, Massachusetts plumbing and heating company with a small public record, and both written reviews on file describe real problems. A 2026 review said the company was contacted about a water heater installed in 2020 that still carries an active manufacturer warranty, and described the company not attempting to check or assist with that warranty. An earlier review, from 2022, described a new toilet installed in June of that year whose plunger mechanism stopped working within a month, and which later came loose and had to be moved; the reviewer called for a repair and was told someone would come the next day. With only two reviews on file, both negative, it's worth asking pointed questions about warranty handling and follow-through before hiring.
Horrendous experience.... I wish there were an option to give less than one star. I contacted this company regarding my water heater, which was installed in 2020 and still carries an active manufacturer warranty. Instead of even attempting to check the warranty or assist with the issue, they immediately pushed for a full replacement. After I provided the make, model, and serial number of the unit, they called back with a quote of $2,800 to replace the water heater — a unit that typically retails for around $600. There was no attempt to look deeper into the problem, explore warranty options, or provide a reasonable explanation for the pricing. The entire interaction felt rushed and dismissive, as if the goal was simply to sell a new unit rather than help the customer. I expected a professional plumbing company to at least investigate a warranty claim before recommending an expensive replacement. Very disappointing experience. Price gauging seems to be new business order for the company who in my opinion should be stripped by their license and all privileges to exist as a plumbing company.
One of the worst experience of my life. New toilet installed in June of 2022. Had to call them as the plugger was not working after a month. The other day the toilet was moving around and I called them right away. They said they would be there the next day and of course they never showed. I was then told they had me on the call sheet for Friday. They never showed or called. I am wondering if they put in a used toilet. DO NOT USE THIS COMPANY.
