10 Best Questions to Ask a Builder Before You Sign

Choosing a builder is one of the biggest decisions you will make when planning a new home. Before you sign with a builder, it is important to ask the right questions so you understand exactly what is included, how pricing works, what protections are in place, and what kind of experience you can expect. Here are 10 of the best questions to ask a builder before you sign, along with what to look for in the answers.

If you are comparing builders in Auckland, these questions can help you make a more confident and informed decision before committing.

How long have you been doing building homes?

Byrne Homes was established by husband and wife team, Joe and Lisa Byrne in 2014. We’ve built a strong reputation in the ‘high-end’ sector, reinforced by quality construction, design knowledge and innovation. Our up-front, honest approach takes the worry out of what can quickly become a stressful journey if not handled by a team with a strong track record. We pride ourselves on having many happy customers, some who have even come back for a second time!

Have you built homes similar to what I want?

Across the years Byrne Homes has built a wide range of styles of homes. Whether clients have come with their own plans, or they are Byrne Homes facilitated plans, we have a vast array of experience and knowledge in building. From in situ poured concrete to masonry builds, gable, monopitch or flat roofs, complex excavation to managing sloping sections, we have seen it all and are here to guide you towards a home that suits your lifestyle, with your ideal spend at the forefront. If you are embarking on an architectural build, ensure that the builder you choose is experienced in this type of construction.

Are you licenced and fully insured?

If a Builder isn’t licensed or properly insured it can put you at risk - of losing your deposit or being shut down. Being a Licensed builder in New Zealand recognises your competency to carry out building work essential to the structure and weathertightness of residential building. As a Licensed Builder, Joe personally warrants the builds we undertake. Byrne Homes are also a Master Builder which means our builds come with a comprehensive 10 year Master Build Guarantee. In addition a Master Builder has to fulfill criteria such as having trade and professional qualifications, building experience, onsite management experience and has been financially vetted. Not only will your build be insured, Byrne Homes also have comprehensive insurance including ‘contract works’ and ‘professional indemnity’.

What makes your process different?

As a Building Management Company we can cover the whole process from design to completion, from feasibility to landscape design. We coordinate all aspects, with many years of strong relationships with our sub trades and consultants. This also allows for competitive pricing benefitting the client. In addition, business owner Lisa is our in-house designer - allowing for ease of collaborating with architects and clients. By removing outsourcing of the design aspects, this creates more cohesion of the finished home and a stress free design process.

How can I access the quality of your builds?

We’ve been awarded 4 Gold Awards over the years at Master Builders Awards, and also a Category Winner Award. These awards are highly revered and recognised as a symbol of quality for those looking to build or renovate. The Gold Standard Awards are given to entrants who achieve 90% of the available points and are judged to be at least 80% above industry standard. 

How will the cost of my build be calculated? 

Once your concept drawings and specification are developed, our Quantity Surveyor prepares a measured estimate to build up the cost of your project in detail. This gives you a much clearer understanding of where your budget is being allocated and helps identify any areas where adjustments can be made early.

At Byrne Homes, we believe pricing should be clear and realistic. Our aim is to give clients confidence before they move too far down the path, which is why we place such a strong focus on early cost clarity and fixed-price contracts wherever possible. We can also provide guidance on likely council fees and other related costs so you have a fuller picture from the outset.

Why can cause a build budget to increase?

Budget increases usually happen when selections change, scope grows, or there are unknowns that could not be fully confirmed at pricing stage. Common examples include excavation, kitchen design, or other items that may still involve allowances early on.

A good builder should explain where these risks sit from the start. At Byrne Homes, we aim to make allowances realistic, reduce unknowns wherever possible, and guide clients through decisions early so there is less chance of unwanted surprises later.

Is there anything that you would exclude from the quote or contract?

This is one of the most important questions to ask before you sign with a builder. Understanding what is excluded is often the fastest way to understand what is actually included, and it helps you compare builders properly.

Common exclusions can include council fees, resource consent costs, Watercare fees, landscaping, curtains and blinds, or other items outside the agreed scope. Asking this question early can help avoid misunderstandings and gives you a much clearer basis for comparing quotes fairly.

Before signing, it is also worth asking whether the builder is offering a fixed-price contract, and if not, why not. Clear pricing and clearly defined inclusions matter. They give you more certainty and make the whole process easier to navigate with confidence.

How long will it take to build my home?

Pre construction time and build times vary for every build, and depend on a build’s complexity.  In addition, resource consents, heritage areas and a development’s design approval can add time prior to breaking ground. We allocate anywhere from 3 - 6 months for concepts to Building Consent approval. And a build time anywhere from 6 to 12 months, once again depending on the size or location of your build. Our clients are able to access up-to-date timelines on where their build is at, information and site photos through our Customer Portal.

Are you able to provide verbal testimonials and visits to completed builds?

When making an investment of this size, it’s perfectly acceptable to want outside validation of a company’s abilities and attitudes. Where possible, we are happy to show you through current or completed builds and put you in contact with previous clients for verbal referrals. Nothing gives you more reassurance of what a builder is capable of than seeing the workmanship in person.

If you are still at the early planning stage and want a better understanding of likely build cost before speaking with builders, our Byrne Homes Cost to Build Calculator is a helpful place to start. It gives you an early indication of budget range so you can begin the process with more clarity.

Choosing the right builder is about more than price alone. It is about clarity, trust, communication, and knowing what kind of experience you are stepping into before you sign. Asking the right questions early can save a great deal of stress later and help you move forward with much more confidence.
