How to Compare Contractor Quotes in Ottawa

Getting three quotes is standard advice, but the real skill is knowing how to compare them. Two quotes for the same renovation can differ by thousands of dollars not because one contractor is overcharging, but because they are quoting different scopes, materials, and standards of work. Homeowners who simply pick the lowest number often end up paying more in the end through change orders, inferior materials, or work that has to be redone. This guide explains what a professional quote should contain, how to compare quotes on a true apples-to-apples basis, and how to read the signals that a price...

Get Enough Quotes to Compare

Comparison only works with a real sample. Too few quotes and you have no basis to judge; the right number gives you a reliable range.

Three Is the Minimum

Always get at least three detailed written quotes from different contractors. Three gives you a reliable range and helps you spot outliers in either direction. For large projects over $100,000, consider four or five quotes, since the dollar stakes of a poor comparison are higher.

Give Every Contractor the Same Brief

To compare fairly, give each contractor the same project brief — the same rooms, the same scope, and the same material expectations. If each contractor is quoting a slightly different project, the prices are not comparable. A clear, written brief is the foundation of an apples-to-apples comparison.

What a Professional Quote Should Include

The quality of a quote tells you a great deal about how the contractor will run your project. Thin quotes lead to surprises.

Detail and Breakdown

A professional quote should include a detailed scope of work specifying what is and is not included, a breakdown of material costs with brands or models where relevant, a labour breakdown by trade, a realistic timeline with start and completion dates, a payment schedule tied to milestones, permit co...

Clarity on Exclusions and Assumptions

Good quotes spell out exclusions and assumptions — what happens if hidden damage is found, who supplies fixtures, how allowances work. Vague quotes leave these gaps to be filled later with change orders, which is exactly how a low headline price becomes an expensive final bill.

Comparing the Right Way

With quotes in hand, the comparison is about substance, not just the bottom line.

Compare Scope and Materials, Not Just Price

Line up the quotes and check whether all contractors are quoting the same work and the same quality of materials. One may have priced premium quartz while another quoted laminate; one may include painting while another excludes it. These differences explain most price gaps. Normalize for scope and m...

Treat the Lowest Quote With Caution

If one quote is 25% or more below the others, ask why. The contractor is likely underestimating the work, cutting corners, using inferior materials, or planning to recover margin through change orders. The lowest quote is frequently the most expensive once the project is complete. The right choice i...

Frequently Asked Questions

How many quotes should I get for a renovation in Ottawa?

At least three detailed written quotes from different contractors. Three gives you a reliable range and helps identify outliers. For large projects over $100,000, consider four or five quotes.

Why are contractor quotes so different from each other?

Most price differences come from differences in scope, materials, and level of detail rather than one contractor overcharging. One quote may include premium materials or work that another excludes. Always normalize for scope and materials before comparing the numbers.

Should I always choose the lowest quote?

No. The lowest quote is often the most expensive in the end because of change orders, corner-cutting, or inferior materials. If a quote is 25% or more below the others, ask why. Choose the best combination of value, detail, communication, and track record.

What should a professional contractor quote include?

A detailed scope of work, material costs with brands or models, a labour breakdown, a realistic timeline, a milestone payment schedule, permit costs and responsibility, cleanup details, warranty terms, and any exclusions or assumptions. A one-page quote for a large renovation is a red flag.

How do I make sure I'm comparing quotes fairly?

Give every contractor the same written project brief — same rooms, scope, and material expectations — so each quote covers the same work. Then compare scope and materials line by line before looking at the bottom-line price.
