Choosing a Builder for Your Bayside Home: Questions to Ask Before You Sign
Choosing a builder is the single decision that shapes everything else about a custom home or renovation, the budget you actually end up spending, how smoothly the process runs, and whether the finished home matches what you pictured.

Interested in discussing
your next project?
Most homeowners across Bayside compare a handful of builders before committing, but it's easy to focus on the wrong things: a glossy portfolio, a friendly first meeting, a quote that looks better on paper than the others.
The questions below are the ones worth asking before you sign anything, whether you're planning a new custom home in Brighton or Hampton or a renovation of an established Sandringham property.
Ask to See Completed Projects Similar to Yours
A builder's portfolio matters less than whether it includes work similar to what you're planning. A builder with an impressive record of new custom homes isn't necessarily the right fit for a heritage-overlay restoration, and the reverse is just as true as period-home experience and new-build experience draw on genuinely different skills.
Ask specifically for projects of a similar scale, budget and building type, and ask whether you can see one in person or speak with the homeowner. A builder confident in their work will generally welcome this; one who deflects or offers only photos is worth asking why.
Ask How Pricing and Contracts Actually Work
A clear understanding of your contract and what is included in the price is essential before construction begins. At Cormack Developments, we work on a fixed-price contract, giving our clients a clear understanding of the agreed project cost from the outset.
When comparing builders, ask what is included in the fixed price, including allowances for items such as tiling, fittings, joinery and finishes. It’s also important to understand how any changes are managed once construction is underway, and how variations are communicated and approved before additional work proceeds.
Your builder should also clearly identify any items that sit outside the fixed-price contract, such as council fees, permits, client selections or costs associated with unforeseen site conditions.
Ask Who You'll Actually Deal With Day to Day
A builder’s principal or director might run the initial sales meeting, but it’s worth knowing who will actually manage your project once construction begins. Ask who your main point of contact will be, who oversees the site, and how often you can expect updates throughout the build.
At Cormack Developments, we use Wunderbuild to keep projects organised and communication clear from commencement through to completion. It provides a central project hub where schedules, documents, site information and communication can be accessed in one place, helping everyone stay informed without relying on lengthy email chains or phone calls.

Good communication is an important part of any successful build. Asking a builder how they manage communication, scheduling and project information gives you a clearer picture of what working with them will actually be like once construction begins.
A well-established process for communicating these issues can make a significant difference throughout a long and complex build.
Ask About the Warranty and Defects Process
Every registered builder in Victoria carries the same statutory warranty obligations — what separates them is how they actually handle a defect once it's reported. Ask how quickly they respond, whether there's a formal process behind that response, and for a real example of how a past issue was resolved.
It's also worth asking a previous client directly, if you can. How a builder behaves after final payment often says more than anything in the sales process.

At Cormack, every defect is logged, photographed and classified the moment it's reported, then tracked through to a signed-off resolution as part of our Defects Liability Period process, so when you ask us this question, we can show you the system, not just describe it.
Watch for These Red Flags
A few patterns are worth treating as genuine warning signs rather than minor quirks: reluctance to provide references or show completed work, a quote significantly lower than every other builder's with no clear explanation why, or pressure to sign quickly, . None of these guarantee a problem on their own, but together they're worth pausing over.
A professional builder should be comfortable discussing how they work, what is included in their quotation, who will manage your project, and how communication will be handled throughout construction. These are reasonable questions when you’re making a significant investment in your home.
At Cormack Developments, we believe the process should be transparent from the outset. A considered approach to construction means being clear about the scope, allowances, responsibilities and potential variables before work begins.

Frequently Asked Questions
Should I ask for references from a builder's past clients? Yes, speaking directly with a past client, ideally for a project similar in scale and type to yours, reveals far more about how a builder communicates and resolves problems than a portfolio alone.
What red flags suggest a builder isn't the right fit? Reluctance to show completed work or provide references, a quote well below every other builder's with no clear explanation, pressure to sign quickly, and vague answers about licensing or contract type are all worth treating seriously.
How long does a builder's warranty period last in Victoria? Registered Victorian builders are required to provide a statutory warranty period on domestic building work, though how promptly and thoroughly a builder actually manages defects within that period varies, it's worth asking directly how they handle it.
Does Cormack Developments welcome these kinds of questions from prospective clients? Yes, as a registered Bayside-based builder, we expect and welcome direct questions about licensing, pricing, process and past projects, and we're happy to put prospective clients in touch with previous homeowners.
