The Most Important Question to Ask Your Builder

Hiring a builder is one of the biggest decisions you’ll make in your project. You want quality workmanship, clear communication, and a process that feels calm and predictable.

But there’s one question we believe tells you more about a builder than almost anything else.

  • It’s not about price.
  • It’s not about timelines.
  • It’s not even about finishes.

The most important question to ask your builder is:

“Are you comfortable with me hiring an independent building inspector to check your work?”

That one question protects your project, and it reveals how your builder thinks.

Why This Question Matters More Than Any Other

Many homeowners feel nervous asking about inspections. They worry it might offend the builder or create tension before the work begins.

We understand that instinct. Building and renovating feels personal.

But here’s the truth.

A builder who runs a professional site and takes pride in their work will welcome transparency. They will not fear third-party verification.

This question doesn’t create conflict. It sets a standard.

What a Great Builder Will Say

When you ask this question, the best response sounds like:

  • “Yes, of course.”
  • “That’s completely fine.”
  • “That’s a great idea.”

We love hearing this question because it shows the homeowner understands how building works. They want a quality outcome, and they want to verify it properly.

What a Red Flag Builder Might Say

A defensive response might sound like:

  • “Why don’t you trust us?”
  • “We don’t need that.”
  • “That’s not how we do things.”

That reaction is a warning sign.

It doesn’t mean the builder is a bad person. It means they don’t welcome accountability. They want you to rely on blind trust.

Blind trust is the most expensive strategy in construction.

What Independent Building Inspectors Actually Do

Independent building inspectors don’t exist to create drama. They exist to reduce risk.

They inspect workmanship and compliance at key stages of the build. They help catch issues early, when fixes are simple and affordable.

This is where homeowners often misunderstand the system.

Many assume the building surveyor checks everything.

They don’t.

Independent inspections also reduce confusion during the build. Many homeowners struggle to know what “good” looks like at each stage. They see framing, membranes, and rough-in services, and they feel unsure because they can’t compare it to anything. An inspector gives you a professional reference point. Instead of guessing, you get clarity on whether the work meets the expected standard at that stage.

This also helps with decision-making. If an inspector flags something early, the builder can fix it quickly while access is still open. That is far easier than discovering the issue after plaster, tiling, or cabinetry hides the area.

What the Building Surveyor Does and Does Not Check

In Victoria, a building surveyor typically attends the site at major stage points, such as:

  • slab stage
  • frame stage
  • practical completion

These inspections matter, but they don’t cover every quality detail homeowners assume someone is monitoring.

Surveyors focus on high-level compliance. They don’t perform deep workmanship audits across every trade and every room.

That’s why independent inspections add value.

The Waterproofing Gap Most Homeowners Don’t Expect

This is one of the most important reasons we recommend third-party checks.

In Victoria, building surveyors are not mandated to inspect waterproofing.

Waterproofing is one of the highest-risk areas in any home. When it fails, the damage often appears months or years later.

By the time you notice the signs, the fix can require:

  • removing tiles
  • opening walls
  • pulling out fixtures
  • rebuilding wet areas

That cost and disruption can be huge.

A staged inspection plan dramatically reduces that risk.

Waterproofing problems don’t always show up as obvious leaks. Sometimes you’ll see small signs first. You might notice swelling in skirting boards, musty smells, grout cracking, or minor paint bubbling. These issues often start quietly and then escalate as water continues to flow through the same weak point.

This is why we recommend checking waterproofing while the area is still visible. Once tiles go down, the repair process becomes expensive and disruptive. You can’t “patch” waterproofing properly from the outside. You need access to the system itself. An early inspection helps you avoid the situation where the bathroom looks finished, but the failure has already started.

When to Bring an Inspector In

Most people think inspections happen only at the end. We recommend a staged approach.

That may include inspections at:

  • slab or base stage
  • frame stage
  • waterproofing stage
  • practical completion

The earlier you identify an issue, the easier it is to resolve.

This approach doesn’t “catch builders out.” It protects the homeowner and the builder.

If you want a practical approach, you can treat inspections like checkpoints that match how the build actually progresses. The goal isn’t to inspect every day. The goal is to inspect when a trade completes a critical layer.

For example, waterproofing is a critical layer because everything relies on it. Framing is a critical layer because it sets the structure of the home, and we want the build quality to be standing in 100 years. Practical completion is a critical layer because you want a professional set of eyes before handover.

When you align inspections with these moments, you protect the project without overcomplicating the process.

Why This Question Helps the Relationship Too

This question also makes the project easier to manage.

If something goes wrong later, the conversation becomes:

“Let’s fix what the inspector flagged.”

Not:

“We think something looks wrong.”

Independent feedback keeps communication calm, objective, and practical.

This question also protects you from one of the most common homeowner regrets. Many people only think about inspections after something goes wrong. By then, the conversation becomes emotional. People feel disappointed. Builders feel defensive. Trust starts to weaken.

When you ask early, you remove the personal tension. You normalise the idea that quality should be verified. That sets the tone for a professional build.

A good builder doesn’t take that personally. They understand that you’re protecting your investment and your peace of mind.

Final Thoughts: Ask Early, Not After Problems Start

If you take one thing from this blog, take this:

Ask the question at the start.

  • Not after you sign.
  • Not after the frame goes up.
  • Not after the bathroom leaks.

Ask early:

“Are you comfortable with me hiring an independent building inspector to check your work?”

  • A confident yes is a great sign.
  • A defensive response is valuable information, too.
  • Either way, you learn what you need to know before you commit.
