Defects During Construction: Finding Something Wrong Does Not Automatically Mean Stopping the Build

You visit the site and see something that does not look right. A wall seems out of line. Waterproofing looks incomplete. A window is in the wrong position. Your instinct may be to demand that everything stop immediately.

Sometimes urgent intervention is justified. Often it is not. The right response depends on what the defect is, what the contract requires and whether continuing work will make the problem worse.

A defect is not automatically a crisis

Seeing something that looks wrong during construction can be alarming. The immediate temptation may be to demand that all work stop. That is not always the correct contractual or practical response.

First identify the issue accurately. Is the work actually defective? Is it incomplete work that will be corrected by a later stage? Is it a departure from the plans or specifications? Or is it simply a construction method that looks unfamiliar while unfinished?

The contract sets the benchmark

Whether work is defective is assessed against the contract documents, plans, specifications, applicable statutory warranties and relevant technical standards. Personal preference alone does not establish a defect.

This is why clear plans and specifications matter. The more precise the agreed standard, the easier it is to assess whether the work conforms.

Raise concerns early and in writing

If you identify a genuine concern, notify the builder promptly. State the location and nature of the issue, attach photographs if useful and ask the builder to inspect and respond.

A calm written record is usually more effective than confronting a subcontractor on site.

Do not direct subcontractors

The subcontractors ordinarily work for the builder, not the homeowner. Direct instructions can interfere with the builder's control of the works and create uncertainty about responsibility.

Raise the issue through the contractual communication channel unless there is an immediate safety emergency.

Should the work stop?

Not every defect justifies stopping unrelated work. A builder may be able to rectify the issue while the project continues. Conversely, if continuing work will conceal or compound a serious defect, urgent technical assessment may be required. Do not issue a direction to suspend the project unless you understand whether you have the contractual right to do so and the consequences of getting that decision wrong.

Independent inspections

An independent building consultant can be valuable at key stages or when a significant technical issue arises. The consultant should identify the relevant standard, describe the defect objectively and recommend appropriate rectification. A report is most useful when it is technical and specific rather than argumentative.

Rectification belongs to the builder in the first instance

Where the builder remains engaged and able to perform the contract, it will usually be sensible to give the builder an appropriate opportunity to inspect and rectify its work.

Engaging another contractor without considering the contractual consequences can create disputes about access, causation, warranty responsibility and cost.

Defects and progress payments

The existence of a defect does not automatically entitle a homeowner to withhold an entire progress payment. Equally, a builder's invoice does not automatically mean the relevant stage has been achieved. Payment rights, defects and stage completion need to be analysed under the particular contract. If the amount is substantial or the issue serious, obtain advice before withholding money.

Keep evidence before work is covered

Photograph significant concerns before plasterboard, waterproofing, cladding or other finishes conceal the work. Retain inspection reports, correspondence and the builder's response.

Good evidence helps everyone understand what existed at the relevant time.

Distinguish rectification from redesign

A request to make defective work comply with the contract is different from a homeowner deciding that they would now prefer a different design or finish. The second may be a variation rather than rectification.

Keeping that distinction clear prevents defect discussions becoming confused with owner changes.

Questions to ask before signing

What standard of workmanship does the contract require?

What inspection rights do I have during construction?

How must defects be notified?

What access must I provide for rectification?

Can I engage an independent consultant?

What happens if I dispute a progress claim because of defective or incomplete work?

Who has authority to suspend the works

The key lesson

Finding something wrong during construction does not automatically mean you can stop the build or withhold payment. Whether work is defective, and what you can do about it, is assessed against your contract, the plans and specifications and applicable standards - so if the issue is serious, obtain advice before acting.

Before You Sign

This guide provides general educational information for South Australian homeowners. It is not personalised legal advice. The effect of any issue depends on the wording of your own contract, schedules, Special Conditions, plans, specifications and the facts of the project. A good builder and a well-understood contract should work together. Before committing to one of the largest financial transactions you may ever undertake, consider having the actual contract reviewed so you understand the obligations, notice requirements and consequences before they are tested on site.
