Chris Lattuada's team is critical to B-Line, because it rarely subcontracts (just $60,000 of its volume is farmed out). Work includes everything from handyman jobs for past clients to $110,000 additions. B-Line's four lead carpenters were previously licensed contractors, and broad experience allows crews to do most tasks. Lattuada has hired five employees through his "Job Line," a permanent phone line dedicated to helping find those who meet B-Line's strict hiring criteria (drug tests and aptitude tests among them).

The team is motivated by the realization that 52 family members rely on B-Line for their lifeblood. Personal growth programs help, too; more than 1% of revenues fund training.
