1

Missing Site Specifics

Every site is different. A quote that doesn't account for sloping land, difficult access, or specific foundation requirements like piles or a reinforced slab will blow out your budget. Always do a thorough site inspection and include those line items.

2

Ignoring Material Volatility

Timber and steel prices can jump quickly in New Zealand. If you quote a job months in advance without a price escalation clause, you eat the difference. Add a material adjustment clause or use current supplier quotes valid for 14 days.

3

Underestimating Labour Hours

Builders often forget weather delays, consent hold ups, or the extra time needed for intricate details. A good rule is to add a 10-15% buffer on labour to cover the inevitable. This keeps your margin safe.

4

Forgetting Compliance Costs

Consent fees, engineer reports, and inspection costs add up fast. Many builders leave these out of initial quotes and then have to absorb them or awkwardly ask for more. Itemise all regulatory costs upfront.

5

Vague Scope = Scope Creep

If your quote says 'install kitchen' without specifying cabinetry type, benchtop material, or appliance brand, you'll get pulled into extras. Write a clear scope with inclusions and exclusions so clients know exactly what they're paying for.
