Who pays when a subcontractor makes a mistake?

Why is the main contractor usually responsible for a subcontractor making a mistake?

Most business owners only sign a contract with the main contractor. That contractor is in charge of hiring and supervising subcontractors.

If a subcontractor does poor work or causes damage, the main contractor is usually required to fix the issue. They handle any disputes with the subcontractor behind the scenes.

In many projects, repairs must be made at no extra cost to you. However, the main contractor holds vicarious contractual responsibility, not strict liability.

What does your contract say about quality and warranties?

Your contract should outline the scope of work, quality standards, and any warranties.

If the finished work falls short because of a subcontractor's mistake, it may count as a breach of contract or breach of warranty by the main contractor.

The contract language will help confirm what the contractor agreed to fix and under what terms.

What to do next

• Review your contract for repair, warranty, and quality terms.
• Document the mistake with photos or written notes.
• Ask the main contractor, in writing, how they plan to fix the issue.
• If the terms are unclear, consider having a Legal Pro review the agreement.

What to consider in your specific situation

These general rules apply in many contractor–subcontractor setups, but your situation may differ depending on several factors.

• The exact language in your agreement with the main contractor, especially around warranties or responsibility for subcontractors.
• Whether the subcontractor's work was required by the project or added later by request.
• State or local laws that outline contractor liability or consumer protections in construction work.
• Any written or verbal promises the contractor made about overseeing subcontractors.
• The size and complexity of the project, which can affect how liability is assigned.
• How serious the subcontractor's mistake is and whether it caused additional damage.
