Contractor quote comparison

Three bids for the same renovation are almost never for the same work. Enter what each one covers and this levels the scopes before it compares the prices — because the cheapest number on the page is usually the one with the most left out of it. Free, and nothing leaves your browser unless you make an account.

Why three bids for the same job come back so different

Because they're rarely bids for the same job. A quote is a contractor's reading of what you asked for, and two readings of the same kitchen can differ by tens of thousands without either party being dishonest. One assumed the existing electrics are fine. One priced a full rewire. One didn't mention electrics at all, which means you'll be paying for whatever it turns out to need — as a change order, at change-order prices.

Comparing the bottom-line numbers on three quotes tells you almost nothing. Comparing them line by line is where the real information is, and it takes about fifteen minutes.

The lines that go missing

These are the ones that separate a cheap bid from an incomplete one. None of them are optional in reality — the work happens either way, and whoever didn't price it will be billing you for it later.

  • Demolition and disposal. Dumpster rental and landfill fees on a full kitchen tear-out are real money, and “owner to remove existing cabinets” is a line that only turns up in the contract you didn't read.
  • Permits and inspection. Either the contractor pulls them or you do. A bid that leaves them out is often a bid from someone planning to work without them.
  • Electrical and plumbing upgrades. Old circuits and old pipework rarely survive contact with new appliances. This is the single most common source of change orders.
  • Subfloor and substrate repair. Nobody can price this honestly before the floor comes up, which is why the good bids carry a stated allowance and the bad ones stay silent.
  • Making good and final clean. Painting after the trades leave, filling the holes, and getting the dust out. Small individually, and consistently absent.

How this compares them

  • You pick which scope lines matter — it opens on the ones bids most often skip, there are 23 to choose from, and you can add your own — then mark each one priced, included, excluded or not addressed, per bid. That's the whole input.
  • Where a bid is missing work another one covers, the gap is filled using a figure a contractor actually wrote down for that same line — never a market average and never a guess. The result is a like-for-like total, and every addition is itemised so you can see exactly what was added and where the number came from.
  • Where several bids priced a line, the middle figure is used rather than the average, because with three bids one outlier drags an average somewhere useless.
  • Deposits, warranties, timelines and verification get checked separately. These are the terms that cost money after signing, which is exactly when comparing bids stops being able to help.
  • If you tell it what kind of project this is, each total is checked against typical cost for that work. Three bids can all be too high, and only an outside range will tell you.

Frequently asked questions

How many contractor quotes should I get?

Three. Two only tells you which of two contractors is cheaper; three tells you roughly what the job costs, because the odd one out becomes obvious. If two bids land close together and the third is 30% under, the third is almost always missing scope rather than beating the market.

Why is one bid so much cheaper than the others?

Nine times out of ten it covers less work. Demolition and disposal, permits, electrical upgrades, subfloor repair, painting after the trades leave, and final clean are the lines that quietly disappear from a low bid. This tool asks about each of them separately for exactly that reason, then re-prices the cheap bid using figures the other contractors wrote down for the same lines.

What is an allowance in a contractor quote?

A placeholder. The contractor has budgeted, say, $3,000 for tile without knowing which tile you'll choose. It's not a price — it's a number that will be trued up later, and if you pick anything above it you pay the difference. Marking a line as an allowance is how you remember that its figure isn't fixed.

How much deposit should a contractor ask for?

Commonly 10–30% up front, with the rest tied to progress milestones. A request for half the job or more before anyone has shown up is worth questioning, and in some places it exceeds what the law allows. Check the rules where you live before you sign.

Does comparing quotes mean I should take the cheapest one?

No — it means you can finally tell which one is actually cheapest. Once the missing scope is priced back in, the lowest sticker price frequently isn't the lowest total. What you do with that is a judgement call about the contractor, not just the number.

Do I need an account?

No. The tool runs in your browser and saves to this device. An account keeps your comparisons available wherever you sign in, which matters because bids arrive over days, not minutes.

Work out the budget before you invite the bids

Knowing roughly what a job costs before the first contractor walks in changes the conversation. The cost estimator gives you a range for your project, size and region, broken into materials, labour and permits.
