Check whether a commercial glazing contracting company holds current NACC (North American Contractor Certification) status before qualifying them for a curtain-wall bid list.

Steps

1. Go to glazingcertification.com/nacc to review program requirements — NACC is described as North America's only ANAB-accredited third-party credential specifically for architectural glass-and-metal (glazing) contractors
2. Confirm eligibility basics: the applicant company must have at least five years of business operations and undergo a multi-day on-site evaluation against documented best-practice and safety criteria
3. Use the live NACC Directory at glazingcertification.com/nacc/nacc-directory (filterable by state/category) to confirm a specific company's current certified status, since certification requires annual recertification and status can lapse
4. Note that as of recent program reporting the certified-contractor pool is a relatively small, specialized group (roughly 100 companies nationally), with additional companies in the certification/recertification pipeline listed separately as 'Active Applicants'
5. If the contractor cites NACC through a regional group (e.g., an NCGMA-subsidized applicant), confirm the individual company (not just its union local or association) is the certified entity
