The cheapest contractor quote usually isn't.
KnownBasis lines up your contractor quotes item by item, prices in whatever each one leaves out, and shows how the real totals compare with what neighbors with similar homes actually paid.
Personal details are removed from every quote before it is stored.
How it works
- Step 1
We read the fine print
Every quote is broken into the same line items — tear-off, materials, permits, haul-away, warranty — however messy the original.
- Step 2
Missing scope gets a price
If a quote leaves out something standard, we add back a local market-rate estimate so you see its Adjusted True Total.
- Step 3
Neighbors set the benchmark
Your quotes are ranked against anonymized pricing from similar homes in your ZIP code — same size, same era.
