Due diligence
What to Look For
Practical guidance from hundreds of real acquisition conversations.
Backlog and Pipeline
- Signed contracts with known margins, expected start dates, and billing milestones give you a clear picture of near-term cash flow from day one.
- Ask for a full backlog report early in the process and distinguish between signed work and verbal commitments.
- Win rates on negotiated work versus competitive bids tell you something real about how clients feel about the relationship.
Clients Who Come Back
- Contractors who win work on reputation rather than low bids tend to have more stable margins and more predictable revenue.
- Whether it's a commercial developer who's used the same GC for three subdivisions or an industrial facility that sends service work every year, repeat clients who've generated work for multiple years are one of the strongest indicators of a durable business.
- Ask what percentage of revenue came from repeat clients in each of the last three years.
A Team That Runs Jobs
- Project managers, superintendents, and foremen who handle estimating, scheduling, and client communication without the owner are what make a contractor truly transferable.
- The question is the same whether you're looking at a commercial firm, a residential builder, or a specialty trade contractor: can the team deliver without the current owner on every job site?
- Spend time with the project team, not just the owner, to get a real sense of how the business actually operates.
Equipment in Good Shape
- In heavy industrial and specialty trade work, the equipment fleet is a major part of what you're buying.
- Well-maintained assets with documented service records and current inspections reduce the uncertainty about what you're stepping into.
- Ask for a full equipment list with hours, age, and maintenance history early in your review.
Licensing and Bonding Clarity
- Contractor licenses, bonding capacity, and specialty certifications are worth understanding before you go deep.
- Some licenses are tied to a qualifying individual who may or may not stay after the sale; bonding capacity gets re-underwritten based on the new owner's finances.
- None of this is a dealbreaker, but knowing the situation early prevents last-minute complications.
