Warning Signs a Subcontractor Is in Trouble
Subcontractors almost never fail without warning. They fail with three months of warning that nobody wrote down.
The signals are visible from the field and from the accounting office, usually at the same time, and usually to two different people who never compare notes. By the time the sub stops showing up, everyone remembers the signs.
This guide is the list, organized by how loud the signal is, with what to do about each one this week. If you want the upstream version of this — how to avoid picking these subs at all — start with subcontractor prequalification.
How to use this
Every signal below has three parts: what you observe, what it probably means, and the action.
One signal on its own is noise. Two from different categories in the same month is a pattern, and a pattern is the point at which you start the staged response at the bottom of this page.
Two signals from two different categories inside 30 days, or any single financial signal, moves the sub from "watch" to "act". This threshold is a judgment call and varies with how big their scope is and how far along you are.
Field signals
Your superintendent sees these first and often does not report them, because each one has an innocent explanation on the day it happens.
| What you observe | What it probably means | This week |
|---|---|---|
| Manpower drops with no notice | Crews moved to a job that is paying, or payroll could not be met | Ask for a written manpower projection by name and date |
| Their best people replaced by unfamiliar faces | Experienced hands left, or the crew is now day labour or a second-tier broker crew | Check whether the new names are on their comp policy; verify supervision |
| No foreman on site | The foreman quit, or is being spread across too many jobs | Require a named full-time foreman in writing; escalate to the owner of the company |
| Material deliveries stop | Credit hold at the supplier | Call the supplier directly. This is the single most informative phone call available to you |
| Deliveries arriving COD or cash on delivery | Credit is gone entirely | Treat as a financial signal, not a field one. Go to the staged response |
| Equipment being pulled off site | Rental returns for non-payment, or redeployment to a job they care about more | Ask where it went and when it comes back. Get the answer in email |
| Their subs and suppliers asking you about payment | They have not been paid and you are being sounded out | Do not discuss amounts. Log the contact, date and name, and tell your accounting office |
| Tools going home at the end of a shift | The crew expects not to come back | This is close to terminal. Escalate the same day |
The last one deserves emphasis. Tradespeople leave their tools on a job they expect to return to.
A superintendent who says "they were light this week" three weeks running has reported a trend and does not know it. Ask the manpower question the same way every week so the trend is visible in your own notes.
Paper signals
These live in the pay application cycle and in your project accounting inbox. They are the easiest to see if anyone is looking, and the most commonly missed because they arrive one at a time.
| What you observe | What it probably means | This week |
|---|---|---|
| Pay app suddenly front-loaded | Cash is needed now and the schedule of values is being used to get it | Verify percentages against physical progress before approving |
| Overbilling against actual progress | Same, further along | Reprice the remaining work. If they walk, you fund the completion out of what is left |
| Requests to accelerate payment outside the cycle | Payroll or a supplier deadline they cannot meet | Say no once and see what happens. The reaction tells you a great deal |
| A request to reduce or release retention early | Retention is now load-bearing in their cash forecast | Decline and document. See retainage |
| Change order claims spiking | Either a real scope problem or an attempt to close a gap created elsewhere | Separate merit from timing. Price them fast, whichever it is |
| Lower-tier lien waivers not coming back | The lower tiers have not been paid | Stop unconditional progress until waivers reconcile to the pay app |
| Preliminary notices from suppliers you have never heard of | New suppliers, or old suppliers now protecting themselves | Log every one. A rising count is a hard signal |
| A supplier calls your office directly | The supplier has already exhausted patience with the sub | Escalate immediately. Suppliers call the GC last, not first |
The lien waiver test
The cheapest ongoing diagnostic you have is requiring conditional lien waivers from the sub and their lower tiers with every pay application, and unconditional waivers for the prior payment.
When the lower-tier waivers stop reconciling, the money you paid last month did not reach the people who earned it. That is not a paperwork failure. That is the sub using your project's cash somewhere else.
Preliminary notice and lien deadlines are state-specific and short. Use the lien deadline calculator to protect your own position before you need it.
Financial signals
These are the loudest. Any single one of them justifies the staged response on its own.
| What you observe | What it probably means | This week |
|---|---|---|
| They ask for joint checks | They cannot pay a supplier out of your payment and are telling you so | Treat as the loudest early signal on this page. See below |
| They ask for payment ahead of the pay cycle | A specific obligation is due and the cash is not there | Understand exactly what the money is for before deciding |
| They are factoring receivables | Bank credit is unavailable or exhausted, and receivables now cost 2–4% a month | Verify who owns the receivable and where payment must be directed |
| A new lien or judgment appears | Another creditor has moved from asking to enforcing | Run a full public records check. Judgments are rarely solitary |
| Insurance lapses for non-payment | Premium was not paid — a small, unavoidable bill they could not cover | Stop work under the subcontract until reinstated. See certificates of insurance |
| A federal or state tax lien for payroll taxes | Payroll withholding was used as working capital | Close to terminal. Escalate to your executive and your attorney immediately |
Why the joint check request is the signal it is
A joint check request almost never arrives as an admission. It arrives as a favor: "Would you mind cutting this one to us and our supplier? It just makes the accounting cleaner."
Read it literally. What has been said is that if you pay them, the supplier will not get the money, and the sub knows it.
That does not mean refuse. Joint checks are a legitimate control and you will often agree to one. It means the request has told you something and you should act on the information rather than just process the check.
Joint check mechanics, briefly
A joint check is a single check payable to two payees — your sub and their supplier or lower tier — requiring both endorsements to negotiate.
Three things to understand before you write one:
- It does not by itself create privity of contract with the supplier. You are not becoming their customer by issuing a joint check, and in most jurisdictions the supplier gains no direct contract claim against you from the arrangement alone.
- It does not release your payment bond exposure. If you are the bonded prime, a payment bond claim from that supplier can still arrive. What a joint check gives you is evidence of where the money went.
- It should be papered. A short joint check agreement signed by all three parties, setting out what the check covers and what it releases, is worth more than the check itself.
In some states, a supplier's acceptance of a joint check affects their lien or bond claim rights, and the extent varies significantly. Have your construction attorney give you a joint check agreement form for the states you work in, once, and then reuse it.
Behavioral signals
These are the softest and the ones people most often talk themselves out of. They are also frequently the earliest.
| What you observe | What it probably means | This week |
|---|---|---|
| The owner stops returning calls | They are triaging, and your job did not make the list | Escalate in writing, to a physical address, with a deadline to respond |
| Key people leave | The estimator, controller or PM saw the numbers before you did | Note who left and where they went. Departures cluster |
| A new "consultant" appears | A turnaround adviser, a claims consultant, or a workout specialist | Find out which. All three mean something different and none of them is routine |
| Communication turns legalistic | Counsel is now involved and the posture has changed from building to preserving | Match the discipline. Every communication in writing from here |
| They stop attending site meetings | Avoidance, or nobody left to send | Make attendance a written contract requirement and enforce it |
| Sudden enthusiasm for extra scope | Chasing new revenue to cover old costs | Be very slow to award more work to a sub already showing signals |
That last one is worth its own line. A struggling contractor's instinct is to bid more work, because new contracts generate mobilization payments and front-loaded billings.
Giving more scope to a sub who is already stretched increases the size of the hole rather than filling it.
What to do, staged
Do these in order. Skipping to the end is how a manageable problem becomes litigation.
Stage 1 — verify quietly
Nothing here is confrontational and nothing here commits you.
- Call their suppliers. Ask whether the account is current. Suppliers usually answer, because you are the source of the money they are owed.
- Check public records for liens, judgments, tax liens and suits, in every county they work in and at the state level.
- Check certificate status with the producer, not with the sub — a policy cancelled for non-payment is confirmable in one call.
- Check their license status with the state board. Suspensions for unpaid judgments are public.
- Ask your own network. Other GCs in your market know. This conversation happens all the time and it costs nothing.
Stage 2 — tighten controls
Now you change how money and materials move, using rights the subcontract already gives you.
| Control | What it does | Watch for |
|---|---|---|
| Joint checks | Ensures the supplier is actually paid from your money | Paper it; see the mechanics above |
| Funds control or an escrow disbursing agent | A third party disburses each draw against verified obligations | Costs money and takes agreement; effective when the sub is cooperating |
| Weekly conditional lien waivers with the pay app | Turns waiver reconciliation into a live diagnostic | Enforce it the first week or it will not hold |
| Increased retention | Preserves funds to complete | Check the subcontract and state retainage statutes before changing terms |
| Direct purchase of long-lead material | Removes the material from their credit exposure entirely | Handle sales tax and warranty transfer deliberately |
| Supplement rather than terminate | You bring in additional labour and backcharge under the subcontract | Follow the notice and cure provisions exactly |
Supplementing under a cure provision is usually far safer than terminating, and it is the step most GCs skip.
Stage 3 — document everything
From the first pattern onward, assume this file will be read by a claims adjuster, a surety and possibly a court.
- Daily reports with actual manpower counts by name and trade
- Photographs with dates
- Every notice given under the subcontract, sent the way the subcontract requires
- A running log of supplier and lower-tier contacts, with dates and names
- Progress percentages recorded independently, not copied from their pay app
The single most valuable document in a default is a contemporaneous record of manpower.
Stage 4 — notify
Two notifications matter, and both have deadlines set by documents rather than by judgment.
If the sub is bonded, notify the surety. Performance bonds contain notice provisions, and sureties are consistently unhappy about being told late — after you have already incurred completion costs they had no chance to control. Early notice preserves your claim and often brings a surety who will help. See how surety bonds work and when a bond claim happens.
Notify the owner per your prime contract. Most primes require notice of events likely to affect schedule or cost, and some require consent before replacing a listed subcontractor — on public work, subcontractor listing statutes may control who you can substitute and how.
If you are the bonded prime, remember the other direction as well: unpaid lower tiers can claim against your payment bond, and that claim lands on your surety and your record. See payment bonds.
Stage 5 — default and termination
Only now, and only with counsel.
Termination for default is the most dangerous remedy in the subcontract. Get it wrong — wrong notice, wrong cure period, insufficient grounds, or an unremedied breach of your own — and the termination itself becomes a breach.
A wrongful termination is frequently more expensive than the performance problem that prompted it. You go from managing a struggling sub to defending a claim for lost profit on the unperformed work, and you have taken on the completion cost anyway.
Before any termination:
- Confirm the specific contractual grounds and that they are documented
- Give the notice and the cure period exactly as the subcontract requires, in the required manner
- Notify the surety before terminating, if bonded, and follow the bond's procedure
- Have a construction attorney review the grounds and the notice before it is sent
- Have a completion plan and a price for it, in hand
This is an attorney's call, not a project manager's. Make it that way in your own procedures so nobody has to be brave about it in the moment.
What this looks like when it goes right
The GCs who handle this well do not have better instincts. They have a weekly habit.
- The superintendent reports manpower by name every week, in the same format
- Accounting flags any pay app that moves more than a few percent ahead of physical progress
- Every preliminary notice received is logged against the sub who caused it
- Certificate expirations are tracked, and a cancellation notice triggers a phone call
- Someone owns the question "which of our subs are we worried about" and answers it monthly
None of that requires software. All of it requires that one person is accountable for noticing.
What to do next
If you are watching a sub right now, run Stage 1 today. It is four phone calls and a records search, and it either resolves your concern or confirms it.
If you want to understand the numbers behind the behavior, read reading a subcontractor's financial statements.
If the sub in question is one you are still deciding whether to award, go back to prequalification and use the risk scorecard.
