Change Orders

What to Do When a Contractor Asks for More Money During Construction

You agreed on a construction price. Work started. Then your contractor presents additional costs you did not expect. Here is how to respond — before you approve them.

Few moments in a construction project are more stressful than the one where the contractor stops and says the job will cost more than agreed. The work is already underway, money is already committed, and walking away feels impossible. That pressure is real — and it is exactly why a mid-project cost request deserves a careful look before you approve it.

Before approving extra charges, the goal is simple: understand what changed, why the cost increased, and whether the additional work is justified. This guide walks through how to do that calmly, without either rubber-stamping the charge or blowing up the relationship with your contractor.

Why construction costs increase mid-project

Additional costs during construction are common, and they come from several different sources. Knowing which one you are dealing with is the first step, because they are not all equally justifiable.

• Missing scope — work that should have been in the original estimate but was left out.
• Unclear estimates — vague line items that are now being "clarified" as extra cost.
• Design changes — you or the designer changed something, genuinely adding work.
• Unexpected site conditions — hidden problems found once work opened up walls, floors, or ground.
• Contractor mistakes — rework caused by an error, which is generally not something the owner should pay to fix.

A change caused by a genuine design decision you made is very different from a change caused by scope the contractor simply forgot to price. Both may arrive as a "change order," but they do not deserve the same response.

Not every change order is wrong

It is important to approach this fairly. Some additional costs are entirely legitimate. Construction uncovers surprises, owners change their minds, and honest contractors raise change orders as the correct, transparent way to handle them.

Framing it this way keeps the conversation professional. You are not accusing anyone — you are asking the change order to meet a reasonable standard before you sign off on it.

What to review before approving additional costs

Run every change order through the same short checklist. It applies whether the extra cost is $2,000 or $30,000.

• Is the extra work actually necessary? Or is it optional, presented as if required?
• Was it included in the original agreement? If it was already in scope, you may be paying twice.
• Is the price detailed? A lump sum with no breakdown cannot be evaluated.
• Are labor and materials separated? Each should be identifiable, not merged into one figure.
• Is there supporting documentation? Photos, measurements, or a written explanation of what changed.

If a change order fails several of these, that is not proof of bad faith — but it is a clear signal to slow down and ask for more before approving.

Questions to ask your contractor

You do not need construction expertise to ask good questions. These four put the change order to a fair test:

• Why was this work not included in the original estimate?
• How was this price calculated — what are the labor and material components?
• Are there alternatives that would cost less or keep us closer to the original budget?
• What happens to the schedule and cost if I do not approve this change?

Clear, specific answers are a good sign. Vague answers, pressure to sign immediately, or reluctance to break down the number are themselves useful information.

When an independent review helps

If the change order is large, unclear, or you simply do not have the time or knowledge to evaluate it under pressure, an independent review is the fastest way to a confident decision. A construction change order review compares the additional cost against your original estimate and scope, checks whether the work was already covered, and returns a plain-language read on whether the price is reasonable and properly documented.

It is worth remembering how you got the estimate in the first place. Many mid-project change orders trace back to a thin or unclear original estimate — which is why reviewing the contractor's estimate before signing prevents so many of these situations. If you are earlier in the process, our guide on how to review a contractor estimate before signing covers what to check up front.

A change order is a decision point, not an emergency. The crew being on site does not remove your right to understand what you are paying for. Taking the time to review it — or having it reviewed — is almost always cheaper than approving it blind.
