A quote 30% or more above regional benchmarks for your city warrants a line-by-line explanation. A quote 30% below them warrants equal scrutiny. Here's how to tell which you're looking at.
How much should renovation quotes vary between contractors?
Quotes for identical renovation scope typically vary 40–60% between contractors in Canada. That spread is normal — labour rates, overhead, and margin differ legitimately between businesses. What matters is whether the lowest number reflects real efficiency or missing scope.
What should a complete renovation quote include?
A complete renovation quote should itemize: materials and labour by trade, permit costs, demolition and disposal, and a contingency allowance of 10–15%. Any quote that bundles these into a single "labour and materials" line makes meaningful comparison impossible.
Before comparing numbers, confirm every quote covers the same scope:
- Permits — Required for most structural, electrical, and plumbing work. A contractor who skips permits transfers legal and financial liability to you. If a quote doesn't mention permits, ask directly.
- Demolition and disposal — Hauling debris costs money. Some contractors itemize it; others leave it out to appear cheaper.
- Finishing work — Painting, trim, tile grouting, and fixture installation are often where scopes diverge between quotes.
- Contingency — Better contractors build in 10–15% for unknowns: rot behind walls, outdated wiring, subfloor damage. This isn't padding — it's accurate forecasting.
How do I know if a renovation quote is priced correctly for my city?
Regional cost data is the most reliable benchmark. Labour rates in Canada vary by as much as 35–40% between provinces — a bathroom renovation in Vancouver is fundamentally more expensive than the same job in Winnipeg. A flat national average tells you nothing useful about a local quote.
RenovateIndex adjusts national cost baselines using Statistics Canada's Building Construction Price Index for each province, and CMHC city-size data for each city. You can review the full methodology here. For specific benchmarks, see: bathroom renovation costs in Toronto, kitchen renovation costs in Calgary, roof replacement costs in Vancouver, or window replacement costs across Canada.
What are the red flags in a low renovation quote?
A quote 30–40% below comparable bids isn't automatically a deal — it usually means something is missing. The most common causes:
- No permit included — Keeps your upfront cost lower, but creates liability when you sell the house or if work is ever inspected.
- Materials substitution — Mid-grade products quoted, budget products installed. Ask for manufacturer names and model numbers on fixtures, windows, and roofing materials.
- Cash-only with no written contract — No paper trail means no recourse if work is deficient.
- No WSIB/WCB coverage — If a worker is injured on your property and the contractor isn't covered, you may bear liability.
What are the red flags in a high renovation quote?
A high quote isn't automatically overpriced — experienced contractors with strong demand legitimately charge more. But some patterns are worth questioning:
- Vague line items — "Labour and materials" as a single number tells you nothing. Ask for a trade-by-trade breakdown.
- Material markups above 25% — Standard contractor markup on materials is 15–25%. Higher is negotiable.
- Pre-emptive scope creep — Some contractors quote worst-case scenarios. Ask specifically what's driving the high-end line items.
How do I compare renovation quotes on a per-unit basis?
For work priced by unit — flooring (per sq ft), roofing (per square = 100 sq ft), windows (per unit) — divide the quoted cost by the quantity and compare to regional benchmarks. This makes comparison objective rather than impressionistic.
If you're replacing windows in Edmonton and one quote works out to $950 per unit while the regional range is $400–$700, you have a specific number to question — not just a vague sense that something is off.
Should the contractor or homeowner pull the renovation permit?
The contractor should pull the permit in almost all cases. When a contractor pulls the permit, they are the contractor of record and legally responsible for ensuring the work passes inspection.
When a homeowner pulls the permit as an "owner-builder," they assume responsibility for scheduling inspections, ensuring code compliance, and remedying deficiencies — even for work done by a hired contractor. Ask every contractor directly: "Will you be pulling the permit for this project?" A refusal is a red flag.
How many renovation quotes should I get?
Get a minimum of three written quotes for any project over $5,000. Written quotes with attached scope documents — not verbal estimates or ballpark figures. The quoting process itself is revealing: a contractor who shows up on time, asks detailed questions about your project, and delivers a clear itemized quote is demonstrating how they will manage the work itself.
