The detail

What a good home building quote includes

A good quote spells out how the job is priced and what's covered — labour, materials, prep and clean-up — so you're comparing like for like. Check what each builder's quote covers before you choose.

Worth knowing: getting two or three quotes is the simplest way to land a fair price — and it costs you nothing.

  • Itemised scope. Every stage listed, site prep to finishing, not a lump sum.

  • Material specs. Exact brand, grade and quantity, not 'good quality'.

  • Exclusions. Driveways, landscaping, fencing and site costs are classic traps.

  • Prime cost and provisional sums. Allowances for choices and site work not priced yet.

  • Licence and insurance. ABN, licence, public liability and home warranty cover.

  • Permits. Who gets permits, soil tests and compliance certificates.

Frequently Asked Questions

Hiring builders

How much do builders typically charge?
Builder costs vary widely depending on the job type and complexity. Minor repairs are generally much less than extensions, small builds or structural alterations that need foundations, framing or specialist input. Most quotes include a call‑out fee plus labour and materials, and the page shows live pricing to help you compare options.
Do builders charge call-out fees?
Call‑out fees are common and typically cover travel and an initial inspection or assessment. This fee is usually separate from hourly labour and materials, and after‑hours or weekend attendance often attracts higher rates. Ask whether a call‑out or minimum charge applies when requesting quotes.
Do builders need a licence in Australia?
Yes. Building work generally needs to be carried out by a licensed builder in every state and territory, and NSW builders are regulated by NSW Fair Trading. Builders should be able to provide their state builder/contractor licence number and show appropriate insurances and ABN/GST registration. In Victoria, domestic building insurance is required above a state threshold for certain contracts.
Do I need a licensed Builder in New South Wales?
In New South Wales, this kind of work generally must be carried out by an appropriately licensed professional. When you compare builders in Unanderra on SureQuote, you can check the credentials each business has provided before you choose.
Is Unanderra a bushfire area?
Yes — Unanderra is classified as bushfire prone land. A fire safety assessment may be required for building works, and some material or design constraints could apply. Check with your council or builder before starting to confirm what's needed.
Could heritage rules affect my renovation in Unanderra?
Some properties in Unanderra are heritage-listed or sit within heritage overlays. If your property is older, check with your council before starting exterior work — there may be restrictions on colours, materials, or design changes.
