Estimates, quotes and contracts
How to compare renovation contractor quotes in Canada
How to get comparable renovation quotes, normalise scope and allowances, spot exclusions and low-ball pricing, and choose the best-fit contractor without relying on reviews.
Renovation quotes can only be compared when they price the same scope, with the same allowances, under the same type of contract. Give every contractor the same written scope (or drawings), ask for a line-item breakdown with tax shown separately, then normalise the quotes: add what one excludes and another includes, raise low allowances to a common figure, and compare payment terms, schedules and warranties alongside price. The best fit is usually the contractor whose quote is complete, whose documents check out on official registers and whose terms protect you, not simply the lowest total.
This guide is part of the estimating method. Work through the quote comparison checklist for each quote, and read the contract checklist before signing.
Step 1: send the same scope to everyone
A one-page scope sheet does more for comparable quotes than anything else. Include:
- rooms and areas, with measurements,
- what is removed, what stays, what is new,
- finish level or specific products where you have chosen them,
- items you will supply yourself,
- who obtains permits,
- your target start date and any constraints (pets, working from home, access).
For larger jobs, paying a designer for drawings first means every contractor prices the same design.
Step 2: ask for the right format
Request quotes that show:
| Item | Why |
|---|---|
| Line items by trade or by room | So you can see where prices differ |
| Allowances as dollar amounts | So you can level them |
| Exclusions listed | The cheapest quote often excludes the most |
| Price before tax, and each tax separately | Totals are comparable only on the same basis |
| Contract type (fixed, cost-plus, time and materials) | Shifts the risk of surprises |
| Unit prices for unknowns | Example: subfloor replacement per sheet |
| Payment schedule and deposit | Cash-flow risk |
| Start date, duration, validity period | Price may expire quickly |
| Warranty on workmanship | Length and coverage |
Step 3: normalise
Put the quotes in a table and adjust each to the same scope. An illustrative example for a kitchen:
| Quote A | Quote B | Quote C | |
|---|---|---|---|
| Price before tax | $48,000 | $42,000 | $55,000 |
| Cabinet allowance | $14,000 | $11,000 | $14,000 |
| Adjust B's allowance to $14,000 | – | +$3,000 | – |
| Permit and drawings | included | excluded: +$1,500 | included |
| Disposal | included | included | included |
| Electrical panel check | excluded: +$500 for an assessment | excluded: +$500 | included |
| Normalised price before tax | $48,500 | $47,000 | $55,000 |
After normalising, the $13,000 gap between the lowest and highest quote is $8,000, and the "cheapest" quote is only $1,500 below Quote A. Now compare the things that are not price.
Step 4: compare what is not price
- Contract type: a fixed price with clear change-order pricing is easier to budget than open-ended time and materials.
- Deposit and schedule: a small deposit with payments tied to stages is safer than a large upfront payment. Ontario's guide for home renovation businesses recommends deposits of no more than 10% of the project cost.
- Holdback: in provinces with a statutory holdback, the schedule should allow for it; see deposits, holdbacks and payment schedules.
- Warranty: written length and scope; who handles subcontractor defects.
- Documents: legal name and address, licence where required, liability insurance, workers' compensation status; see contractor licensing and insurance checks.
- Communication: a clear, specific quote delivered when promised is itself evidence of how the job may be managed.
Red flags in a quote
- A single lump sum with no breakdown.
- "Permits not required" for work that clearly changes structure, plumbing or wiring.
- A large deposit, or full payment before materials arrive.
- A discount for cash or for skipping tax.
- A price valid only if you sign today.
- No legal business name, only a first name and a mobile number.

Why we do not rank contractors
Online ratings and reviews can be useful hints, but they are hard to verify, and a contractor's past jobs may not resemble yours. Official sources are more reliable for the checks that matter: licence registers (such as the RBQ register in Quebec), workers' compensation clearance, the GST/HST Registry, and court or consumer protection records where your province publishes them. Ask for references from jobs similar to yours and speak to them directly.
How many quotes?
Two or three complete quotes on the same scope are usually enough for a typical project. More than that takes contractors' time without adding much information, and good contractors may decline to quote if they sense a price auction.
FAQ
Should I always choose the middle quote?
No. Choose the quote that is complete, comparable and backed by checks and terms you are comfortable with. Sometimes that is the lowest, sometimes not.
Can I negotiate a quote?
You can ask about options that reduce cost (different finishes, phasing, owner-supplied items). Pressing for a lower price on the same scope can lead to corners being cut; ask what would change.
What if the contractor will not give a breakdown?
That makes comparison and change orders harder. At minimum ask for a breakdown by trade or by room and the allowances.
Is a verbal quote enough?
No. In Ontario, for example, consumer agreements over $50 for future services must be in writing. Get everything on paper.
