How the Verdict Is Decided
| Where your quote lands | Verdict | What it usually means |
|---|---|---|
| More than 10% below the low estimate | Below range | Often a missing-scope flag: confirm base prep, reinforcement, and mix strength are included. |
| Just below the low estimate | Low end | Competitive pricing or a high-volume contractor. Verify scope, then a reasonable deal. |
| Inside the low-to-high range | Fair | Market-rate price for your spec and state. The expected, defensible band. |
| Just above the high estimate | Above range | Often site access, finish detail, or removal work. Ask for an itemised breakdown. |
| More than 10% above the high estimate | Well above range | Itemise the bid and collect at least two more quotes before signing. |
Expected ranges are national contractor averages scaled by state cost index, covering labour, materials, forming, reinforcement, and finishing. They exclude excavation and base prep, demolition, permits, drainage, and pump-truck access. Confirm whether your quote includes those before comparing.
Quote Validator FAQ
Compare the quoted total against the expected installed range for your exact slab spec: square footage, thickness, reinforcement, finish, and your state's cost index. A fair quote falls inside that range. The validator above does this automatically: a quote inside the low-to-high band is market rate, more than 10% under usually means scope was left out, and more than 10% over should be itemised before you accept it.
