Three Questions to Ask Before You Hire a Builder (That Most People Never Think to Ask)

By Laura Budge | 5 June 2026

Choosing a builder is one of the biggest decisions you'll make. Here's how to get it right.

There's a particular kind of dread that settles in when a renovation goes wrong. Not the dramatic stuff — the leaking roof, the structural issue, the obvious disaster. It's the slower burn: the builder who stops returning calls, the budget that quietly creeps, the weeks of silence where you're left wondering what's actually happening inside your own home.

Most of these stories don't start with bad workmanship. They start with the wrong questions — or no questions at all.

When people are choosing a builder, the conversation tends to go one way. How much will it cost? How long will it take? Have you done something like this before? These are reasonable things to ask. But they only tell you part of the story. They tell you what the builder thinks the project will cost and when they think they'll finish. They don't tell you what it's actually like to work with them.

That's what the following three questions are designed to find out.

Why the Interview Matters More Than the Quote

Before we get into the questions, it's worth saying this plainly: the builder you choose will be in your home, sometimes for months. They'll be making hundreds of small decisions on your behalf. They'll be managing your money, your timeline, and the welfare of the building your family lives in. Choosing them based primarily on price is a bit like hiring a surgeon because they quoted the lowest rate.

This isn't to say price doesn't matter — of course it does. But the quote is just numbers on a page. What you're actually buying is a relationship, a process, and a team of people. The best way to understand what you're getting is to ask the right questions upfront.

Here are three that will tell you almost everything you need to know.

Question One: How Do You Handle Unexpected Problems?

Every renovation uncovers surprises. Every single one.

It might be a wall that's wetter than expected. A subfloor that needs replacing. A structural issue hiding behind the cladding that nobody could have known about from the outside. In reclads especially — which are Cove Build's bread and butter — you're opening up the walls of a home that's been weather-tight for years. What's underneath isn't always what anyone anticipated.

This is just the nature of building work. It doesn't make a builder bad. What does make a builder bad is how they handle it.

When you ask a builder "how do you handle unexpected problems?", you're listening for a few specific things. First, do they acknowledge that problems will arise? A builder who says everything will go exactly to plan either hasn't done much building or isn't being straight with you. Second, do they have a clear process for communicating issues as they come up? That means telling you what they've found, what the options are, and what it means for the budget and timeline — before they just crack on and fix it.

In the industry, these are called variations. Any work that falls outside the original scope should be formally documented and agreed upon before the additional work begins. Good builders have a system for this. Less organised ones tend to figure it out later, usually when they hand you a final invoice with items you weren't expecting.

Ask: "Can you walk me through how a variation works on one of your jobs? What does the conversation look like, and how do you document it?"

The answer will tell you a lot about how organised they are, how transparent they are, and how much respect they have for your ability to make informed decisions about your own project.

Question Two: Can I Speak With a Recent Client?

References are standard. Most builders will offer them if you ask, and most homeowners never follow up.

That's a missed opportunity, because a ten-minute phone call with a recent client will tell you more about what it's actually like to work with a builder than any amount of brochures, Instagram posts, or project photos.

The key word here is recent. Not a job from three years ago, not someone whose renovation was completed before COVID, and definitely not a testimonial printed on their website that may have been written by anyone. Ask to speak with someone they've worked with in the last six to twelve months. The experience should be fresh enough that the client can give you a real, textured account.

What are you trying to find out? A few things.

First, communication. Did the builder keep them in the loop? Were they easy to get hold of? Did they feel informed throughout, or did they spend weeks chasing updates? Second, how were problems handled? Because there were problems. There always are. The question is whether the client feels like they were managed well or whether they were caught off-guard by things they should have been told earlier. Third, would they use this builder again? And critically — why or why not?

That last question tends to produce the most honest answers. People who had a good experience usually say so without prompting. People who had a frustrating one, even if the work itself was fine, will often tell you if you ask the right way.

Ask: "I'd love to chat with someone you've worked with recently — ideally from a project in the last year. Would that be okay?"

A builder who's proud of their recent work won't hesitate. A builder who starts steering you toward older projects or written testimonials is worth being curious about.

Question Three: How Will They Keep You Informed Throughout the Build?

This might be the most important question of the three, and the one least often asked.

Poor communication is the most common complaint homeowners have about builders. Not bad work. Not cost blowouts. Not delays — though those come up plenty too. It's the silence. The weeks of not really knowing what's happening in your own home. The feeling of being left on the outside of a process that's profoundly affecting your life.

A great build that's poorly communicated feels like a bad experience. A build with a few hiccups that's communicated really well tends to feel like a great experience, because the client feels like a partner rather than a bystander.

So ask specifically: how does communication work on a day-to-day basis? Who is your point of contact on site? If you have a question on a Tuesday afternoon, who do you call? How often will you receive updates, and in what format? When a decision needs to be made, how is that conversation had, and how is the outcome recorded?

At Cove Build, we use project management software — specifically Rave Build — that gives clients a real-time view of their project's progress. Updates, documents, photos, and task schedules all live in one place, and clients can access them whenever they like. It means nobody's ever left wondering what happened last week or what's coming up next.

Not every builder works this way, and that's fine. But good builders will have some kind of system. They'll be able to explain it clearly. And they'll be able to tell you who you're talking to when something comes up — because something always comes up.

Ask: "What does communication look like on a typical week during the build? Who is my main contact, and how do you handle questions or concerns if they come up?"

If the answer is vague, or if the builder looks slightly uncertain, that's useful information too.

A Note on What You're Not Asking

You'll notice none of these questions are about the quality of the work. That's deliberate.

Quality is assumed. If a builder isn't producing good work, they probably won't survive long enough to be on your shortlist. By the time you're in the room asking questions, you can reasonably assume the technical capability is there.

What separates a good building experience from a bad one is almost always the softer stuff — the communication, the honesty, the ability to manage uncertainty without making the client feel like they're in the dark. The three questions above are designed to get at exactly that.

They're also designed to be respectful. You're not interrogating the builder. You're trying to understand how they work and whether that style of working suits you. A good builder will appreciate the questions. They'll have clear answers, and they'll probably be glad you asked.

Before You Sign Anything

If there's one thing to take from this, it's that the conversation before the contract is signed is just as important as the contract itself.

Building and renovation projects are significant. For most homeowners, they represent years of saving, months of planning, and a genuine emotional investment in the place they live. Getting the builder selection right matters — not just for the finished product, but for the experience along the way.

Ask about problems. Ask to speak to recent clients. Ask about communication. Then listen carefully to the answers.

The builders who answer those questions well tend to be the builders worth hiring.

At Cove Build, we work on high-quality renovations, reclads, and architectural new builds across Tauranga and the Bay of Plenty. If you're in the early stages of thinking about a project and want to have an honest conversation about what's involved, we'd genuinely love to hear from you. No obligation — just a straight answer.
