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.

Finishing trades sit at the end of the build, so they feel the cycle last and hardest, and revenue per firm is the lowest of any segment here. Labour is the whole cost base and the whole constraint; the firms that scale are those that solved crew retention, not those that won the most work.
