SJ Carlson Fire Protection

We are a family business, that for the past 25 years has serviced Northern Illinois and Southern Wisconsin's Fire Sprinkler needs. We strive for our customers to be given the most accurate quotes, in the shortest amount of time. Our accredited team of engineers seek to design sprinkler systems with the latest technology, and get plans swiftly approved. The shop is open at 4:30 am and does all its own fabrication and welding. Our union sprinkler fitters are safe and expedient, but most of all, able to answer any of your questions. We have proven results that stem from our experience and resources. I had the privilege of working with my father and founder Paul Rockwell. His philosophy was the same as the two generations before him: "To do everything with Integrity." For protecting lives is just as important as our legacy. A legacy that spans over 90 years and is as rich as our future is bright and I am honored to be a part of it.
