How to compare contractor quotes without being misled by the total

Why the totals mislead

Two quotes for the same kitchen can differ by thousands of dollars and still not tell you which one is cheaper. A total only means something when both quotes describe the same work, the same materials and the same extras. Often they don't.

Common reasons the numbers don't line up:

• Different scope. One contractor includes painting, permits or haul-away. The other leaves them out or marks them "by owner."

• Allowances instead of prices. An allowance is a placeholder budget, such as "electrical: allowance $600." If the real work costs more, you usually pay the difference.

• Vague materials. "Countertops, supply and install" could mean laminate or stone, and the price gap between those can be large.

• Different payment terms. A low total with a large deposit carries a different risk from a higher total paid in stages.

The Federal Trade Commission advises against automatically choosing the lowest bid and suggests asking for an explanation when estimates differ widely. Canada's Office of Consumer Affairs makes a similar point: ask contractors to quote on the same specifications so the estimates can be compared.

Step 1: Normalize the scope before you compare

Before looking at any total, write one short scope list that every contractor quotes against. For a kitchen it might be:

1. Remove and dispose of existing cabinets and countertops.

2. Supply and install the new cabinets (list the style, count and finish).

3. Supply and install countertops (name the material and thickness).

4. Plumbing: reconnect the sink and dishwasher, new faucet.

5. Electrical: name the number of new outlets and lights.

6. Permits, inspections and disposal.

7. Painting and final cleanup.

Send the same list to each contractor. If you already have quotes, mark every item on your list as included, excluded, an allowance or not mentioned. "Not mentioned" is a question to ask, not proof that it's included. Our 13-point checklist of what a quote should include helps you spot the gaps.

Step 2: Compare line by line (a sample)

Here are two synthetic quotes for the same kitchen. The companies are fictional.

Sample quote A, Ridgeline Builders (synthetic): total $14,200

• Cabinets and quartz countertops, supply and install: $8,900

• Plumbing, sink and dishwasher reconnection, new faucet: $1,950

• Electrical, fixed price (six outlets, under-cabinet lighting): $1,400

• Permits and dumpster: $1,150

• Painting: $800

• Deposit: 10% on signing, then stage payments

Sample quote B, Northgate Renovations (synthetic): total $11,900

• Cabinets and countertops, supply and install: $8,450 (countertop material not named)

• Plumbing rough-in and fixtures: $1,900

• Electrical: allowance $600

• Painting: $950

• Permits and debris disposal: by owner

• Deposit: 50% on signing

At first glance B is $2,300 cheaper. Now adjust it so it covers the same job:

• Add the permits and disposal you would have to arrange yourself. Using quote A's figure as a rough guide, that's about $1,150.

• The electrical line is an allowance. If the work costs what quote A charges at a fixed price, you would pay about $800 more.

• Ask what countertop material $8,450 buys. If it isn't quartz, the cabinet lines are not comparable yet.

Adjusted, B is about $13,850 before any countertop difference. The real gap is closer to $350 than $2,300, and B asks for five times the deposit. These adjusted figures are estimates for comparison, not prices, so ask each contractor to confirm in writing.

Step 3: Look at the payment schedule

The payment schedule matters as much as the total. A sensible schedule ties each payment to finished work you can see, such as "cabinets installed" or "final inspection passed." The FTC suggests not paying everything up front and not making the final payment until the work is done and you're satisfied.

Some states, provinces and territories limit how much a contractor can take as a deposit, and the rules differ. Check your local consumer protection or licensing body before you sign, and see how much deposit a contractor should ask for. If one quote asks for a much larger deposit than the others, ask why and what it pays for.

Canada's Office of Consumer Affairs also notes that the law in some places may require you to hold back part of the payment until major work is finished, under construction lien rules. Check the rules for your province or territory.

Step 4: Questions to ask each contractor

Send everyone the same questions, in writing, so the answers are comparable:

1. Is everything on my scope list included? Which items are excluded or left to me?

2. Which lines are allowances? What happens if the real cost is higher or lower?

3. What exact materials, brands or grades are you pricing?

4. Who gets the permits and arranges inspections?

5. Who removes debris, and is a dumpster included?

6. What is the payment schedule, and what work does each payment match?

7. How are changes handled? Will every change be priced in writing before the work is done?

8. What are the start date, completion date and expected length of the job?

9. What warranty do you give on labor, and what manufacturer warranties apply?

10. What is your license number, and can you show proof of insurance?

Queensland's building regulator suggests also asking what happens if the project is delayed and whether the builder has other projects that could affect your timeline.

Step 5: Check the contractor, not just the quote

A clear quote from an unlicensed or uninsured contractor is still a risk. Licensing rules depend on where you live and on the trade:

• US: licensing is set by states, and sometimes by counties or cities. The FTC suggests confirming a license with your state or county and asking for proof of insurance.

• Canada: the Office of Consumer Affairs suggests checking with your provincial or territorial consumer affairs office, and notes that many trades, such as plumbers and electricians, need to be certified.

• Australia: each state and territory runs its own license register. In Queensland, the QBCC register also shows disciplinary history.

Keep a record

Keep each quote, your scope list and every written answer together. If you sign, the contract should match what you compared. If it doesn't, ask about the differences before signing.

Line up your own quotes

It will read the quotes you've received, line up the same items side by side, quote the lines that differ, flag allowances, exclusions and missing details, and prepare questions to send each contractor.
