A family-oriented business built on hard work and dedication. Bill Cone started working for his father installing 1″ residential water services. Now the company installs residential and commercial services, all the way up to 12″ water mains. Over the years, the company’s work has expanded to RPZ valves, fire sprinkler systems, and DT-201 vault boxes. With this background and skillset, the company is a one stop shop for all things water construction.
We generate business from referrals, not advertisments. We have spent close to nothing on advertising over the years, simply because our work speaks for itself. With a stellar reputation across Long Island, the company is on a short list of contractors for 3 major Suffolk County authorities.
