Comparing Contractor Quotes & Spotting Hidden Costs

Two quotes for the same project can differ by tens of thousands of dollars — and the lower number isn't always the better deal. Knowing how to read a construction quote is one of the most valuable skills a client can have.

Why quotes differ so much

A quote reflects assumptions. When two contractors price the same project differently, it usually means they've made different assumptions about scope, materials, allowances, and what happens when the unexpected shows up. A low bid often isn't cheaper — it's just less complete.

Where hidden costs hide

• Allowances set too low — placeholder figures for finishes or fixtures that balloon once real selections are made
• Vague scope — "site work" or "finishing" with no detail invites change orders later
• Excluded items — permits, disposal, cleanup, or testing left off the quote entirely
• Unrealistic timelines — a schedule that ignores Calgary's weather or permit realities becomes a cost problem mid-build

What a strong quote looks like

A professional quote is detailed, specific, and honest about assumptions. It breaks down scope clearly, states what's included and excluded, and uses realistic allowances. It should make you more informed, not less.

At Catapulta Contracting Inc., we believe a quote is the first demonstration of how we work: transparent, thorough, and built on planning rather than optimism. The goal isn't to win with the lowest number — it's to give clients a number they can trust.

Before you sign, ask questions. The right contractor will welcome them.
