Overview

Specialty Interior Contractors covers the building-finishing trades — drywall and insulation, painting, flooring, tile and terrazzo, finish carpentry, and other interior finishing. At ~$184B across ~127,000 establishments, it is a highly fragmented collection of local finishing contractors serving both new construction and renovation/tenant-improvement work.

Demand combines new build with a large, steadier renovation and commercial tenant-improvement base, giving the segment some resilience to new-construction cycles. It is intensely local and labor-driven, with limited but emerging consolidation.
