How to Read a Contractor Quote

Three quotes, three prices, three scopes — comparing them feels impossible until you know where the bodies are buried. Here is the anatomy of a quote and the five red flags that should kill a bid on sight.

Anatomy of a real quote

SectionWhat good looks like
Scope of workSpecific tasks, quantities, and locations — "replace 22 squares architectural shingles, GAF Timberline HDZ" not "new roof"
MaterialsBrand, model, grade specified — the exact unit, not "AC system"
LaborBroken out or credibly bundled, with crew size and timeline
AllowancesCapped dollar figures for unknowns (decking per sheet) — never open-ended
ExclusionsExplicit list: permits, electrical, disposal, painting — so "cheap" bids show their gaps
Payment termsMilestone-based; deposit under 30% for most jobs (many states cap it by law)
WarrantyWorkmanship term separate from manufacturer term, both in writing

Five red flags

How to compare three bids

Normalize scope first: same materials, same inclusions, same warranty terms — ask bidders to re-quote to a common spec if needed. Then compare: total price, exclusions, timeline, payment schedule, and warranty. The best bid is rarely the cheapest number; it is the cheapest complete number from a verifiable contractor.

The three-quote rule: always get three written quotes to a common spec. One bid is a price; three bids are a market. Outliers in either direction deserve questions, not signatures.
