How Do I Know If My Contractor Is Being Honest About Extra Work Needed?

Midway through your construction project, your contractor calls with the news every property owner dreads: “We ran into an issue, and it’s going to cost extra.”

In the construction industry, change orders are a normal part of the building process. Unforeseen site conditions, design tweaks, and material availability can all necessitate adjustments to the original plan. However, change orders can also be a source of friction, budget overruns, and, in worst-case scenarios, exploitation.

So, how do you distinguish between a legitimate, necessary change order and an inflated upsell? Here is your professional guide to verifying the necessity of extra work and ensuring your contractor is being completely transparent.

1. Understand the Anatomy of a Legitimate Change Order

Before you can verify a change order, you need to know what a proper one looks like. A legitimate change order should never be a vague verbal estimate. It must be a formal, written document that includes:

• A detailed description of the extra work.
• The specific reason the work is necessary (e.g., "Discovered termite damage behind drywall").
• An itemized breakdown of costs (materials, labor, equipment, and overhead/profit).
• The impact on the project timeline.
• A space for both parties to sign before the extra work begins.

If your contractor is handing you a napkin with a rough number scribbled on it, you have every right to pause and request formal documentation.

2. Spotting the Red Flags

While most contractors operate with integrity, the high-pressure environment of construction can sometimes lead to corner-cutting. Watch out for these warning signs:

• Vague Justifications: Phrases like "it’s just how the code is" or "we need to upgrade this to make it right" without providing specific code references or technical reasons.
• Lack of Visual Evidence: If the issue is hidden (like plumbing or structural framing), the contractor should be providing photos or videos of the problem before asking for more money.
• Urgency and Pressure: Being told, "You need to sign this right now or we’ll have to stop work," without giving you time to review the details.
• Scope Creep: Suggesting "upgrades" or "better materials" under the guise of them being strictly necessary for the project's success.

3. How to Verify the Necessity of Extra Work

When a change order lands on your desk, do not sign it immediately. Follow these steps to verify the necessity of the extra work:

A. Review the Original Scope of Work

Go back to your initial contract. Often, what a contractor claims is "extra" is actually already included in the base price. Carefully review the original scope of work, specifications, and drawings. If the work was reasonably inferable from the original plans, it should not be a change order.

B. Request "Proof of Condition"

If the change order is due to an unforeseen condition (e.g., rock excavation, hidden water damage, outdated electrical wiring), ask for visual proof. A professional contractor will gladly provide timestamped photos, videos, or even core samples. If they cannot show you the problem, you cannot verify the solution.

C. Ask for an Itemized Breakdown

Never accept a lump-sum change order. Ask for a detailed breakdown of material costs and labor hours. This allows you to see exactly what you are paying for. If the labor hours seem disproportionately high for the task described, ask the contractor to explain the methodology.

D. Check the "Unforeseen Conditions" Clause

Most professional construction contracts include a "Differing Site Conditions" or "Unforeseen Conditions" clause. This clause outlines exactly how hidden issues should be handled, priced, and approved. Ensure your contractor is following the exact protocol laid out in your contract.

E. Get a Second Opinion

For major change orders that will significantly impact your budget, it is entirely reasonable to get a second opinion. You can hire an independent inspector, a structural engineer, or even consult another trusted contractor to verify that the proposed extra work is actually necessary. While this costs a small fee upfront, it can save you thousands of dollars in unjustified change orders.

4. Best Practices for Managing Change Orders

The best way to handle change orders is to set the ground rules before the first shovel hits the dirt.

• Establish a Clear Approval Process: Define in your contract exactly who has the authority to approve change orders and the required turnaround time for your review.
• Mandate Written Approval: Include a strict clause stating that no extra work will be paid for unless it is documented in a signed change order prior to the work being performed.
• Maintain a Collaborative Tone: Remember that verifying change orders isn't about assuming your contractor is lying; it’s about exercising good fiduciary duty. Approach the conversation collaboratively: "I want to make sure I fully understand the issue so I can approve this quickly and keep the project moving."

Change orders are an inevitable reality in construction, but surprise invoices shouldn't be. By demanding detailed documentation, requiring visual evidence, and rigorously comparing extra work against your original scope, you protect your investment.

A trustworthy contractor will never be offended by your due diligence. In fact, they will respect a client who pays attention to the details, as it ensures a transparent, successful project for everyone involved
