How we grade quotes

Nothing on this site is a scoring model you have to take on faith. The grader is a short set of rules applied to published ranges, and this page is all of them.

The four verdicts

What happens, in order

  1. We read your quote in your browser and split it into line items. Nothing is uploaded.
  2. If a line matches a known add-on pattern — attic insulation, for example — we flag it on what it is, not on its price, and explain the distinction.
  3. Otherwise we look for a published range for that item. No match means no verdict.
  4. We work out the unit price. If your quote states the quantity, we use it. If not, we use the perimeter you entered. If we have neither, no verdict.
  5. We compare that unit price to the range and assign one of the four verdicts above.
  6. We attach the sources and a confidence label, then repeat for the next line. The totals only add up lines we could actually benchmark.

What the confidence label means

Confidence starts at whatever the underlying benchmark carries, then drops a level in two situations: when we had to derive the unit price from the perimeter you typed rather than a quantity your quote stated, and when the benchmark has not been re-checked in six months. A wide published range — bait station installs run from $650 to $3,800 — stays labelled low, permanently. That spread is the honest answer.
