Managing subcontractors: schedule, quality and getting paid
6 min read
As a general contractor, you only look as good as the subs you hire. Coordinating trades so the electrician isn't waiting on the framer, catching quality problems before they're buried behind drywall, and keeping payment fair and on time — that's the real job. Do it well and the same crews come back for your next project at their best price.
Sequencing is the whole game
A construction schedule is really a chain of dependencies. Framing has to be inspected before insulation; insulation before drywall; drywall before paint. When one trade slips, every trade behind it slips too — and idle crews cost money and goodwill. Build a schedule that names each sub's start date and, just as important, the completed work they're relying on being ready when they show up.
Confirm each sub 24–48 hours before their start, and give them as much notice as you can when dates move. A sub who trusts your schedule reserves their best crew for you; a sub who keeps getting sent home learns to overbook and put you last.
Catch quality before it's buried
The cheapest defect to fix is the one you catch before it's covered. Rough-in plumbing and electrical, waterproofing, flashing and structural connections all disappear behind finishes within days. Walk the work at those milestones with the drawings in hand, and don't approve cover-up until it's right. A ten-minute inspection now beats opening a finished wall later.
Pay fairly and finish clean
Prompt, fair payment is the reputation that makes the best subs answer your call first. Tie payments to completed, inspected milestones, collect a lien waiver with each check, and don't sit on invoices. On the back end, keep a running punch list from the first week rather than trying to reconstruct one at the end — a handful of tracked small items is a calm closeout instead of a frantic one.
Key takeaways
- Sequence the trades on a real schedule — each sub needs a clear start date and the completed work they depend on before they arrive.
- Inspect at the right moments — before cover-up (rough-ins, waterproofing) is your last cheap chance to catch a defect.
- Communicate scope in writing to every sub — the same clarity you want from an owner, your subs need from you.
- Pay subs promptly against completed milestones and collect lien waivers — fast, fair payment is why the best crews prioritize your jobs.
- Keep a running punch list — small unfinished items tracked as you go prevent a chaotic scramble at closeout.
