SEE WHAT BuildWhiz CATCHES BEFORE YOU SIGN
Here's what we flag in real quotes
Most quotes look complete — until the variations start. We check every line to catch what's missing, unclear, or likely to cost more later.
Not listed anywhere in the contract. Waterproofing wet areas is mandatory under the NCC — missing it almost always leads to a costly variation.
OTHER COMMON PATTERNS WE FLAG:
Landscaping
Not mentioned anywhere in the quote. Often left out or deferred, meaning you'll need to budget for it separately later.
Soil conditions
"Site conditions may vary" — wording like this leaves room for additional costs once work begins.
Included — but limited
"Flooring included" — often only covers basic materials, not installation or upgrades.
Your report checks your entire quote — not just these examples.

Now that you've seen what it finds — these are the patterns we see again and again in real quotes:
Gaps in coverage
Key items left out of the quote that you'll need to pay for later — landscaping, driveways, connection fees, blinds. They add up fast.
Low allowances
Amounts that look fine on paper but won't cover what you actually want. A $15,000 kitchen allowance might barely cover flat-pack — let alone installation.
Unclear scope
Vague wording that gives room for costly variations during the build. "Soil conditions may vary" could mean an extra $30,000. Better to catch it now.

Check My Quote Before I Sign
Know what's missing before you sign
Check My Quote Before I SignMost people only find these issues after they've signed.
Once the contract is signed, these become variations.
Our checklist includes state-specific items — from cyclone ratings in the north to bushfire assessments in the south — so BuildWhiz knows what to look for based on where you're building.
"Picked up missing site costs and vague allowances I would have missed completely. Saved me thousands in potential variations."
"I thought my quote was solid — turns out three key items weren't even included. Glad I checked before signing."
"The email to my builder was worth it alone. He came back with a revised quote the next day."
