Duncans Janitorial Inc

What Duncans Janitorial Inc does

Duncans Janitorial Inc is a privately held commercial janitorial services company founded in 2007 by David C. Duncan and headquartered in the Tri-State region spanning Indiana, Kentucky, and Illinois. The company delivers recurring cleaning and facility maintenance services to a diversified client base that includes commercial offices, industrial and warehouse facilities, hospitality operators, religious and nonprofit organizations, and residential customers. Core offerings encompass office cleaning, industrial and warehouse cleaning, carpet cleaning, floor maintenance, post-construction cleanup, and deep cleaning, supplemented by residential add-ons such as window cleaning, laundry, trash removal, and ironing.

The business is operated with a crew-based service delivery model, with approximately 20 employees executing contracted cleaning engagements under the founder's oversight. The company holds BBB Accreditation, indicating adherence to established trust and consumer-protection standards, and has sustained continuous operations for 18 years, suggesting durable customer relationships and operational discipline typical of mature regional service providers. Customer relationships are anchored in recurring commercial contracts with embedded training, site-specific protocols, and on-site supervision, creating modest switching friction and baseline revenue stickiness.

Revenue is generated through contract-based pricing for commercial engagements and project- or visit-based pricing for residential and post-construction work. The go-to-market approach relies on local reputation, referrals, and BBB visibility rather than a formalized sales operation, and the technology stack is conventional for the category, with no disclosed software platform or AI-enabled tooling. The combined footprint positions the company as a small, regionally anchored janitorial operator with limited concentration risk but constrained scale and limited technology differentiation.
