Cabinetry and Architectural Millwork Deals

I’ve been seeing more interest in acquiring millwork and cabinetry businesses lately. One thing that consistently gets underestimated in diligence: The gap between estimating assumptions and actual production throughput. On paper, margins look solid. On the floor, labor flow, rework, and engineering constraints tell a different story. That disconnect tends to show up quickly post-close. Curious how others are evaluating this in deals. Happy to compare notes with anyone actively looking at deals in this space.
