About Us

Who We Are

We are a full service fire protection contractor. We began in February of 1994 after Automatic Sprinkler Corporation of America discontinued their construction department and later sold to their largest competitor, Grinnell Fire Protection. At that time, we added sales, design, service, and inspections. As a result, we became the full service company you expected when you called Automatic. In 2013, the second generation owners took over daily operations.  We are the same local people who have been designing, installing, inspecting, servicing, modifying, and adding to fire protection systems for many years. We continue to provide the same quality service, attention to detail and timely installation you expect.DeMaranville’s staff of  Nicet certified designers, licensed installers, and inspectors work with customers and contractors to give personal attention to their Fire Protection needs.  With systems tailored to your needs, you can expect exceptional service, the highest quality products and the ability to meet your schedule.
