PLUMBING is the foundation of our diverse company.
Nelson Mechanical Design, Inc. was founded by two master plumbers. Plumbing is the foundation of our diverse company.

We offer a wide range of plumbing systems from residential and commercial plumbing installations… to custom designed and fabricated water features. We use traditional products as well as new technologies such as AquaPex water systems and Clivus composting toilet systems.

We offer over twenty years of plumbing experience and specialize in new construction and renovations. We service what we install and fully warrant our installations
Residential
Commercial
We install plumbing systems for every size and style home. We have a great network with local island general contractors and architects to plan your system before the home is built. We offer a great line of products for residential hot water heating and custom fixtures.

Our plumbing experience starts with the commercial application. We have installed commercial plumbing systems from small office spaces to community centers with battery bathrooms and function halls.

Hot Water Heating: Electric, Propane Power Vented, Direct Vented, Indirect, Tankless Gas/Electric
