5 Common Claims Against Contractors and How to Avoid Them

Contractor disputes are more common than you think. Whether it’s a home renovation, a commercial build, or a specialty upgrade, contractor-related claims can derail projects, drain bank accounts, and tarnish reputations. For both clients and contractors, understanding these pitfalls—and how to avoid them—can mean the difference between a nightmare and a smooth, successful job.

Here are the five most common claims against contractors—and practical steps to keep your projects on track.

1. Poor Workmanship

What it means:
Poor workmanship claims arise when the finished product doesn’t meet industry standards, building codes, or the project’s own specifications. It’s not just about the work “looking bad”—it’s about failing to deliver safe, usable, and lasting results.

Typical examples:

• Leaky plumbing, electrical issues, or faulty HVAC installations

• Uneven flooring or shoddy framing

• Inferior materials used without approval

• Paint jobs with streaks, drips, or poor coverage

How to avoid it:

• Detailed Contracts: Spell out every expectation, material, and standard in writing.

• Frequent Site Inspections: Regularly check progress and quality—don’t wait until the end.

• Tie Payments to Milestones: Make progress payments only after approved work stages.

• Third-Party Quality Checks: For large jobs, hire independent inspectors for peace of mind.

2. Project Delays and Cost Overruns

Why they happen:
Few things frustrate clients more than missed deadlines and surprise costs. Delays often lead to extra living costs, lost business income, or project chain reactions. Cost overruns can quickly turn a dream project into a financial burden.

Typical causes:

• “Scope creep” (adding work not in the original plan)

• Material shortages or price increases

• Labor shortages or management missteps

• Unforeseen site issues (e.g., hidden damage, bad weather)

How to avoid it:

• Build in Buffer Time and Contingency Funds: Expect the unexpected.

• Clear Change Order Process: Get every addition or change in writing, with new costs and timelines approved before work continues.

• Regular Communication: Weekly updates prevent small problems from becoming big ones.

• Accurate Initial Estimates: Get thorough inspections and realistic timelines up front.

3. Contract Disputes and Scope Creep

The root of most disputes:
A vague or poorly written contract is a recipe for problems. Disagreements often start when the contract doesn’t clearly define what’s included—and what’s not.

Common contract issues:

• Ambiguous descriptions of work (“upgrade bathroom fixtures” vs. “install Model X brushed nickel fixtures”)

• No formal process for approving changes

• Missing payment schedules or unclear final payment terms

How to avoid it:

• Crystal-Clear Scope of Work: List every task, material, and deliverable in the contract.

• Formal Change Order System: Make any changes official with signed paperwork (including costs and schedule).

• Dispute Resolution Clause: Add steps for mediation or arbitration to handle disagreements before they become lawsuits.

• Legal Review: For larger jobs, have your contract reviewed by a construction attorney.

4. Payment Disputes

Why they occur:
Disagreements over invoices or payment schedules are a top cause of legal claims. Clients may feel overcharged or believe work isn’t complete. Contractors may face cash flow issues or have trouble collecting final payments.

How to avoid it:

• Transparent Payment Schedule: Spell out deposit, progress payments, and final payment details in the contract.

• Link Payments to Work Completion: Only request payment after pre-defined milestones are met.

• Detailed Invoices: Provide itemized invoices so clients can see exactly what they’re paying for.

• Immediate Communication: Address payment concerns as soon as they arise to prevent escalation.

5. Negligence and Site Safety Claims

The risks:
Contractors are legally and ethically obligated to maintain a safe job site—for both workers and the public. Safety lapses can lead to serious injuries, property damage, or even death. Negligence claims are among the most expensive and damaging.

Common hazards:

• Falls from ladders, scaffolding, or roofs

• Unsecured tools or materials causing injury

• Inadequate site security leading to accidents or theft

• Failing to follow building codes or safety standards

How to avoid it:

• Strong Safety Protocols: Regular safety meetings, clear signage, and proper protective equipment.

• Mandatory Training: Make sure every worker is trained for their tasks and aware of site rules.

• Carry Proper Insurance: General liability and workers’ comp insurance protect you and your team.

• Document Everything: Keep records of inspections, incidents, and training for every job.

Conclusion: Proactive Steps for Fewer Claims and Happier Projects

The most common claims against contractors—poor workmanship, project delays, contract disputes, payment issues, and negligence—are largely preventable. The secret?

• Clear contracts and documentation

• Open communication

• High safety and quality standards

These practices don’t just keep you out of legal trouble—they build trust, drive referrals, and help your business grow. Set high standards, keep lines open, and protect your reputation with every project.
