Experience ... the difference

We pride ourselves on being leaders in our industry. Aedan Gleeson was a founding member of the Firestop Contractors International Association, and was its first president. He was instrumental in the development of accreditations for the firestop industry - the FM 4991 and UL Qualified Firestop Contractors programs - and Gleeson Powers was one of the first FM 4991 Approved Firestop Contractors, and the first UL Qualified Firestop Contractors. We remain one of the only contractors in the United States to hold both accreditations. We have 5 DRIs (Designated Responsible Individuals) on staff, one CHC (Certified Healthcare Constructor), Intertek trained and certified fire door inspectors, and a fully trained workforce in our specialty trades.

We are also the developers of the Life Safety Tracker System®, a customized fire barrier management software that has helped solidify fire barrier management and documentation as best practice in life safety compliance.
