Managing Subcontractors on Multi-Trade Jobs Without Losing Control

When you're the general contractor on a multi-trade job, your reputation is on the line for work you didn't do. If the electrician is late, the customer blames you. If the plumber's work fails inspection, the customer blames you. If the painter leaves a mess, the customer blames you.

Managing subcontractors well is one of the highest-leverage skills in contracting. It's also one of the least taught.

Selecting subcontractors before you need them

The worst time to find a subcontractor is when you need one for a job that starts in two weeks. Contractors who wait until they have a job to find a sub are always working with whoever is available — which is often not who they'd choose if they had time to be selective.

Build your sub network before you need it. For each trade you regularly need — electrical, plumbing, HVAC, painting, tile — have at least two qualified subs you've worked with and trust. Know their capacity, their rates, and their scheduling lead time.

Vet subs the same way you'd want a GC to vet you: license verification, insurance certificates (general liability and workers comp), references from other GCs, and ideally a small job together before you put them on a large project.

Contracts with subcontractors

Your subcontractor agreements need to be as specific as your customer contracts. The scope of work, the price, the schedule, the payment terms, and the warranty expectations should all be in writing and signed before work begins.

Critical clauses for sub agreements:

**Schedule requirements.** When does the sub start? When must they be complete? What are the consequences of delay? A sub who misses their schedule window on a multi-trade job can push back every subsequent trade — and the cost of those delays falls on you.

**Insurance requirements.** Require a certificate of insurance naming you as additional insured. This is standard practice and any legitimate sub will have no problem providing it. If a sub balks at being named as additional insured, that's a red flag.

**Payment terms.** Pay subs after the work is inspected and approved, not before. A common structure is to pay subs after the customer has paid you for that phase of work — this aligns your cash flow with theirs and gives you leverage if there are quality issues.

**Warranty and callback responsibility.** The sub's warranty should match or exceed the warranty you're providing to the customer. If you're warranting workmanship for one year, your sub agreement should require the same.

Coordinating the schedule

Multi-trade jobs require a sequenced schedule. Rough-in trades (framing, rough electrical, rough plumbing, HVAC) have to complete before insulation and drywall. Finish trades (flooring, painting, trim, finish electrical, finish plumbing) have to sequence correctly so they don't undo each other's work.

Build a master schedule that shows every trade, their start date, their expected completion date, and their dependencies. Share it with every sub. Update it when things change. When a trade slips, immediately assess the downstream impact and communicate to the affected subs.

The most common scheduling failure is assuming that because a trade is scheduled to finish on Friday, the next trade can start Monday. Inspections take time. Punch list items take time. Build buffer into your schedule between trades.

Managing quality in the field

You can't be on every job every day when you're running multiple projects. But you need a presence on every job at key milestones: before drywall closes (to verify rough-in work), before flooring goes down (to verify subfloor and paint are done), and at substantial completion (to walk the job before the customer does).

Develop a relationship with each sub where they know you'll be checking their work and you know what to look for. Subs who know their work will be inspected do better work than subs who think no one is watching.

How Vevvo helps you manage multi-trade jobs

Vevvo's job management lets you track every trade on a project as a separate task with its own status, assigned sub, and schedule. You can see at a glance which trades are complete, which are in progress, and which are coming up — without having to call five different people to get a status update.

Sub agreements, insurance certificates, and inspection photos are all stored against the job record. When the customer asks about the status of the electrical rough-in, you have the answer in front of you in seconds.
