How to Fire a Subcontractor: Notice, Documentation, and Back-Charges

Terminating a subcontractor mid-project is one of the most disruptive and expensive events in construction.

A replacement sub on a partially complete scope typically costs 15–30% more than the original contract. The delay between termination and remobilization averages 2–4 weeks even when a replacement is available.

Done without proper documentation, termination can expose you to wrongful termination claims, lien filings, and breach of contract liability.

Done correctly — with written notice, documented failures, and a structured back-charge log — termination is an enforceable contract right that protects your project and your business.

Strong documentation systems such as construction photo documentation software help create defensible records before performance issues escalate.
Note: Construction contract law varies by state. Consult a construction attorney before terminating any subcontractor on bonded or high-value projects.

The Four Situations That Justify Termination

1. Persistent Performance Failure

Repeated missed milestones.
Installation defects after written correction notices.
Inadequate crew size.
Failure to coordinate with other trades.

Daily logs and crew tracking tools like GPS timesheets for contractors make labor shortages difficult to dispute.
What does not qualify:

• One corrected defect
• Minor owner-caused delay
• Scope changes initiated by you

2. Safety Violations

Repeated OSHA or site safety violations after documented warnings justify removal.

If safety reporting is weak, enforcement becomes difficult. Clear documentation aligned with your construction management app for general contractors ensures site compliance and written records.
Immediate removal is justified when:

• There is imminent danger
• The sub re-offends after written warning
• There is deliberate disregard for safety

3. Financial Default

Warning signs:

• Supplier calls regarding unpaid invoices
• Preliminary lien notices
• Requests for accelerated payments outside contract terms

A financially unstable subcontractor increases lien risk and project delay.

4. Abandonment

The sub stops showing up — no crew, no communication, no response. Material breach. Terminate immediately once abandonment is documented, but still send written notice to protect your legal position.

Step 1: Document Performance Failures Before You Act

Your documentation file should include:

• Daily reports with crew counts
• Timestamped photos of defective work
• Prior written warnings
• Schedule variance analysis
• Correspondence log

Consistent documentation protects your legal position. Many contractors formalize this process using jobsite photos and daily progress tracking systems.

Step 2: Issue a Written Cure Notice

A cure notice is a formal written demand to correct specific deficiencies within a defined period. Most subcontracts require it before termination for default — and many states require it even if the contract doesn't.

Requirements:

• Written — certified mail or hand-delivery with acknowledgment for significant contracts
• Identifies specific contract provisions violated
• Describes specific deficiencies in detail
• States a reasonable cure period — 48 hours for safety/urgent issues; 5–7 days for performance
• States the consequence of failure to cure (termination)

Cure Notice Template

[Date]

[Subcontractor Company Name] [Address] Attn: [Name, Title]

Re: Notice to Cure — [Project Name] — [Subcontract Agreement dated ___]

Dear [Name],

This letter serves as formal notice pursuant to Section [X] of our Subcontract Agreement dated [date] that [Sub Company] is currently in default of the following subcontract obligations:

1. [Specific deficiency — e.g., "Failure to maintain the minimum crew size of [X] workers as required by the Project Schedule dated [date]. During [start date] through [end date], your crew has averaged [X] workers, causing [X]-day delay to [milestone]."]

1. [Specific deficiency — e.g., "Defective installation of [work] at [location], specifically [describe defect], which does not conform to [spec section/code requirement]."]

You are hereby directed to cure each deficiency within [five (5) / forty-eight (48)] calendar days — by [cure deadline date]. Specifically, you must:

1. [Specific corrective action for deficiency #1] 2. [Specific corrective action for deficiency #2]

Failure to fully cure by [cure deadline date] may result in termination of your subcontract for default, at which point [GC Company] reserves the right to complete the work using other forces and to back-charge all costs in excess of your subcontract value against amounts due or to become due to you.

This notice does not waive any rights or remedies available to [GC Company] under the subcontract, at law, or in equity.

Please confirm receipt and provide your written cure plan by [24 hours after notice].

Sincerely, [Name / Title / Company]

Sent via: [certified mail / email with read receipt / hand delivery]

Step 3: Evaluate — Cure or Terminate?

Consider allowing more time if:

• Measurable progress is documented
• Replacement causes greater delay
• The subcontractor presents a credible recovery plan

Proceed with termination if:

• Cure deadline expires without improvement
• Financial instability increases lien exposure
• Performance failures are systemic

If performance management processes are weak across projects, review this construction project management guide to improve workflow oversight.

Step 4: Issue the Termination Notice

Your termination letter must:

• Reference the cure notice
• Confirm failure to cure
• Set site removal deadline
• Reserve back-charge rights
• State final accounting timeline

Do not terminate verbally.
Do not skip required cure notice steps.

Termination for Convenience: The Lower-Risk Alternative

Termination for convenience (T-for-C) removes the subcontractor for business reasons, not default.

Under T-for-C:

• Sub is paid for work completed
• Sub receives overhead and profit on completed work
• Sub is not entitled to anticipated profit on unperformed work

This clause should exist in every subcontract agreement.

Back-Charges: Documenting Replacement Costs

Replacement cost premiums increase as project completion increases.

Back-charge documentation should include:

• Replacement subcontractor invoices
• Corrective work invoices
• Re-inspection fees
• Delay damages
• Project management time

Organized documentation prevents disputes later.

Final Payment Disputes: Protecting Your Position

Before issuing final payment:

• Obtain third-party valuation
• Photograph defective work before remediation
• Secure unconditional lien waivers
• Notify your insurer if litigation risk exists

Never withhold undisputed amounts.
Doing so can create breach exposure.

Common Termination Mistakes

• Terminating verbally
• Skipping cure notice
• Retroactive documentation
• Allowing continued work post-termination
• Failing to notify insurer

Most termination disputes stem from documentation gaps, not legal technicalities.

Final Thoughts

Firing a subcontractor is a business decision, not an emotional one.

The earlier you document, the stronger your position.
The clearer your communication, the lower your legal risk.
The more structured your systems, the fewer terminations you’ll need.
