A 22 percent fee on a $130k superintendent is $28,600 for one hire. Staff a division for a year through agencies and the invoice rivals a project manager's salary. None of that is an argument that agencies are bad; it is an argument that paying retail for every routine hire is a choice, and most contractors can stop making it.
What the fee actually buys
Strip the branding and an agency sells four things: a database of candidates, the labor of outreach and screening, market knowledge, and speed born of doing this all day. For genuinely rare searches, a VP of preconstruction, a mission critical director, that bundle is worth the money. For the recurring middle of the market, supers, PMs, estimators, foremen, service techs, the same four things are now available as software, at a flat cost instead of a percentage.
The math that changes the decision
Agencies price per hire; platforms price per year. The crossover is brutal: one avoided placement fee typically covers a year of tooling, and every hire after that is margin. A contractor making eight field-leadership hires a year through agencies is spending $150k to $220k on fees for work that is, in 2026, mostly automatable sourcing, texting and screening.
What "in-house" has to include to work
Contractors who tried to in-source hiring with a job board subscription and a shared spreadsheet concluded it does not work. They were right: the missing piece was never the posting, it was the production system around it.
- Reach beyond applicants. A candidate network to source from, not just a post that waits. The people you want are employed.
- Outreach that runs itself. Texts, emails and follow-ups on schedule, with replies landing in one place, or the pipeline dies the first busy week.
- Screening before the phone rings. Licenses, certs, pay expectations and deal breakers collected automatically, so humans only talk to plausible fits.
- Market pay data. Half of agency value is "what does this role pay here." Live local bands replace that phone-a-friend.
- A bench that persists. Every screened non-hire is the head start on the next search, if the system keeps them warm.
Keep agencies for what they are great at
The sane end state is a split: software runs the recurring hiring engine, agencies get the searches that genuinely need a headhunter's network and discretion. Your agency relationships improve too, because you stop resenting invoices for hires you could have made yourself.
How to start without betting the company
Pick one role family you hire repeatedly, run it fully in-house on proper tooling for a quarter, and compare cost-per-hire and time-to-fill against your agency baseline. The numbers make the decision; they usually make it quickly.
