How to Check a Contractor Quote

A fair quote is an itemised quote

A fair contractor quote is an itemised one. A quote that breaks the job into named materials, labour, dates and extras can be checked line by line against the work in front of you. A quote that is a single round number — “the bathroom, $12,000, all in” — cannot be checked at all, because there is nothing in it to check. Treat that as the first red flag: not proof of dishonesty, but proof that you have no paper trail when the argument starts.

Here is the checklist, in order: what a checkable quote includes, how the money should move, one quick arithmetic test, the warning signs, and how to compare three quotes without fooling yourself.

What a checkable quote includes

Before any numbers, read the quote as a document. A checkable quote contains all seven of these; a quote missing two or more is not ready to sign, however friendly the conversation was.

• The exact scope. What is included and, just as important, what is not. “Supply and fit” versus “fit only” changes a price by thousands.
• Named materials. Brand, range and grade — not just “tiles” or “paint”. A named product can be priced in two minutes; a vague one can be swapped for something cheaper later.
• Labour as its own line. Separate from materials, so you can see what the work itself costs.
• Start and finish dates. Not “soon” or “in the autumn”, but weeks on a calendar, with what happens if they slip.
• Who handles permits and disposal. Applications, inspection fees, skip hire and waste removal, each assigned to a name.
• A written warranty. How long it runs, what it covers, and whether the manufacturers’ warranties on materials pass to you.
• Licence and insurance details. The licence number and the insurer, printed on the document — not promised verbally.

If a line is missing, ask for it in writing before you compare prices.

Payment benchmarks: deposits and staged payments

How the money moves matters as much as how much there is. A deposit of 10 to 30 percent is normal for most jobs: it books the crew and covers the first materials order. The safe pattern after the deposit is staged payments tied to completed stages — a share when the first fix is done and inspected, a share at a defined milestone, and the balance at the end. Each payment should follow work you can see and touch, never precede it.

Two rules protect you more than any other. Paying more than half the total before work starts is the classic danger sign: the leverage has flipped, and if the contractor vanishes you are funding someone else’s job. And never pay the final balance until the snagging list is done — the small defects, missed paint lines and unfinished seals that only appear at the end. The final payment is the only leverage you have to get them fixed, and it evaporates the moment it leaves your account.

The split test: materials versus labour

One quick test, needing nothing but the quote itself: on most jobs, materials run at roughly 40 percent of the total and labour at roughly 60 percent. It varies by trade — a rewire is mostly labour, while a kitchen with stone worktops can tip toward materials — so treat it as a shape, not a law. But a quote wildly off that shape is worth questioning, politely, with the numbers in hand. Materials billed at 80 percent of a labour-heavy job suggests padding; labour at nearly everything on a materials-heavy job suggests the materials will appear later as extras.

Red flags that mean walk away

Any one of these can have an innocent explanation. Two or more together is a pattern, and patterns are what you are paying attention to.

• Pressure to sign today. A discount that expires at the door is a sales device, not a price.
• Cash-only, with no paperwork. No contract, no receipt, no comeback.
• A quote far below two others. It rarely stays low; it grows later, through “unforeseen” extras you cannot refuse mid-job.
• Vague “allowances” for the expensive items. A small allowance for tiles or fittings you have not chosen yet is where budgets go to die.
• No fixed address or licence number. Nothing you can verify, and nobody you can find if it goes wrong.

Comparing three quotes properly

Get three quotes, and give each contractor the same written scope — the same rooms, the same named materials, the same dates. Then compare them line by line, not just by the totals: the scope lines, the materials lines, the payment schedule. The middle quote with a full breakdown is usually a safer buy than the lowest quote with none. Before you start, set your own ceiling with the Remodel Budget Calculator — your budget is the baseline every quote is judged against, not a number the market invents for you.

Run the whole project, not just this quote, through the Home Improvement Project Checklist, so the stages before and after hiring are covered too. And if a quote makes you wonder whether the job should be hired out at all, work through the four questions in our guide to DIY vs hire a contractor — some jobs shrink happily into a weekend, and some should never be attempted without a licence.
