A family business, built in Denver since 2007
On the Spot Firestop began in 2007 with two founders, Gilbert and Ines, who built the company from the ground up to support their family.
Safety, precision, and integrity came first then and still do. As the company grew, so did the sense of family. We treat every client, employee, and partner with the care we give our own.
Today the next generation is stepping in to carry the company forward, with the same standards and the same warmth.
