About

Originally known as GNS Contracting Corp., Mr. William Gremler and Mr. Cliff Saunders founded the company in 1974 in order to provide solutions to the growing number of water issues arising on the North Fork of Long Island. In 1996, current owner Mr. John Scaramucci purchased the business, which had expanded its service area to most of Suffolk County and some of Nassau County. GNS's name was changed to GNS/Mermaid Water Systems, with intentions to eventually phase out the “GNS” portion (GNS stands for 'Gremler and Saunders'). Today, Mermaid has increased the density of its coverage in Suffolk and Nassau and expanded even further, servicing clients in Brooklyn, Queens, and Manhattan. In addition to changing the culture of the company and adding many new faces, Scaramucci also developed a sound method of testing and personally certifying any equipment that was to be sold and installed. As a former carpenter and owner of Scaramucci Construction, John’s mantra is “measure twice, cut once.” He has applied this to all aspects of the company and his life, just ask any of his colleagues or his three sons, two of which are current GNS/Mermaid employees.

Reviews

Installed a reverse osmosis water filtration system for our drinking water at our kitchen sink and through our refrigerator drinking water and ice maker.

GNS Mermaid Water Systems is a very reputable company that does exactly what they say they are going to do. The owner himself came to our home and explained all of the services they provide and the benefits and costs. Although they also will install both a whole house filtration system and a water softener system, we chose to go with only the drinking water system, at least at the time. An appointment day and time was set and two men arrived promptly at the appointed time. They knew exactly what to do and how to take into account all the minor idiosyncrasies of our basement. They did exactly what we had been told would be done, and they did it to perfection. The system has worked perfectly for these past six months, and we just received a postcard in the mail from them reminding us that it is time for us to call and set up a time for them to come out and replace the filter that needs to be replaced every six months. The water tastes great and is crystal clear. I would recommend them to anyone interested in purchasing any water improvement system in their home.

This small company is excellent. Came when they said they would and did exactly what they promised. Did it efficiently, professionally, and with experienced and dedicated installers. I would recommend them to anyone.
