Qualified contractor programs

The qualified contractor programs provide architects, authorities having jurisdiction (AHJs), general contractors, manufacturers, building owners and others with a way to identify contractors that comply with the qualified contractor program requirements.

For many years, UL has been classifying firestops and spray-applied fire resistive materials (SFRMs) and listing them in UL Fire Resistance Directory. Now, through the UL qualified contractor program, UL provides the industry with a way to identify contractor firms involved in the installation of firestops and SFRMs that have been assessed by an independent third party. In Canada, UL's affiliate ULC also provides a wide range of certification services including certifying and listing firestops in the Canadian Fire Resistance Directory. Firestop contractors interested in coverage for Canada can do so through ULC's qualified firestop contractor program.

The programs include contractor firms that have demonstrated knowledge and a comprehensive management system specifically focused on the selection and installation of firestop systems or spray-applied fire-resistive materials (SFRMs). The contractor firm systems audited under this program provide an integrated approach (demonstrated knowledge and management system) to controlling the processes in addressing architectural, AHJ and customer requirements. Once program requirements are met, the contractor is issued a certificate effective for one year. The contractor may also use the qualified firestop contractor program marking or qualified SFRM contractor program marking. Contractors are re-audited annually by UL to assess continued compliance with the program.

If you are an architect, AHJ, general contractor, manufacturer or building owner, please visit our qualified contractors list to find qualified contractors.

If you are a contractor, these qualified contractor programs are available to you:

  • Qualified firestop contractor program
  • Qualified spray-applied fire-resistive material (sfrms) contractor program
