What Southeast Interior Systems does
Southeast Interior Systems is a privately held, family-owned commercial interior construction subcontractor founded in 2011 by Kathryn Blank and headquartered at 4100 Revolution Park Drive in Charlotte, North Carolina. The firm specializes in light gauge and structural metal framing, commercial drywall installation, acoustical ceiling systems, trusses, and EIFS/Stucco for commercial interior buildouts. Unlike pure specialty subcontractors, SIS operates under its own General Contractor license (NC License No. 75054), which enables turn-key tenant up-fit delivery including in-house mechanical and electrical scope — a meaningful capability expansion over typical framing/drywall trade contractors.
The company's go-to-market is entirely subcontractor-driven: SIS sells to the Southeast's leading general contractors rather than directly to building owners or developers, and project acquisition flows through direct GC relationships and referrals rather than competitive open bid markets at scale. Revenue is project-based and quote-driven, with no recurring or subscription revenue component. The firm serves five primary vertical segments — healthcare facilities, educational institutions, corporate offices, retail and automotive, and mission-critical facilities — with named end-clients including Novant Health, Atrium Health, Carolinas Medical Center, Presbyterian Hospital, Queens University of Charlotte, Western Carolina University, Lowe's, Cabela's, Hendrick Automotive Group, and Sentara. The WBE-certified firm executes projects across the Southeast, with portfolio evidence of work in North Carolina, South Carolina, West Virginia, Virginia, and Indiana, including marquee projects such as a $15M Presbyterian Hospital bed tower expansion and a 165,000 sf Western Carolina University residence hall. The organization is small — disclosed headcount of 1–10 — relying heavily on field labor subcontracting consistent with trade contractor economics, with no institutional funding, M&A activity, public market listing, or disclosed revenue.
