GET 3-5 QUOTES MINIMUM
A single concrete quote tells you nothing. Three to five quotes show you the real market, reveal scope differences, and expose contractors trying to overcharge or cut corners. This number matters because concrete work typically costs $6–$12 per square foot for basic slabs—on a 1,000 sq ft driveway, that's $6,000–$12,000. A difference of just $2 per square foot adds up to $2,000 in savings or hidden costs.
Why Three Is the Minimum
One quote leaves you blind. You don't know if the price is fair, what's included, or why they quoted that number. Two quotes help, but you still can't identify patterns. Three quotes establish a baseline. By five quotes, you'll see clear clustering around a market rate, plus outliers that demand explanation.
When comparing, look at these specifics:
- Scope of work: Does every quote include site prep, grading, base material, reinforcement, and finishing?
- Material specs: One contractor might quote 4 inches of 3,000 PSI concrete; another 3 inches of 2,500 PSI—very different durability
- Timeline: Rush jobs cost more; 2-week turnarounds versus 6 weeks reveal scheduling assumptions
- Warranties: Some offer 1-year coverage; others 5 years on cracks
- Finishes: Broom finish, salt finish, or polished concrete are priced differently
When 3–5 Quotes Applies
This rule applies to most concrete projects over $2,000: driveways, patios, garage floors, and structural slabs. For smaller jobs—a 4×8 ft shed pad or concrete steps—you might get away with two solid quotes from vetted contractors.
It applies less strictly if you're using a referral from a family member with recent concrete work. Personal trust shortens the due diligence, but you still want a second opinion to confirm pricing fairness.
When it doesn't apply: Emergencies requiring same-day repair, or jobs under $500 where quote collection time isn't worth the effort.
How to Compare Effectively
Request quotes in writing. Ask each contractor to break down costs: labor, materials (concrete, rebar, gravel base), equipment rental, and finishing work. This reveals which contractors are padding labor versus material costs.
Create a simple spreadsheet with these columns:
| Contractor | Price | Timeline | Warranty | Key Included | Concerns |
|---|---|---|---|---|---|
| ABC Concrete | $8,400 | 3 weeks | 2 years | Base prep, rebar, finish | Lowest price—ask why |
| XYZ Paving | $9,200 | 2 weeks | 1 year | Includes site cleanup | —— |
| Local Concrete Pro | $8,800 | 3 weeks | 5 years | Premium sealer included | Higher baseline |
A quote 40% below others isn't a steal—it's a red flag. The contractor may be underestimating labor, skipping essential steps (proper base, correct slope for drainage), or running into cost overruns mid-project that become your problem.
Conversely, the highest quote isn't always best. Sometimes premium pricing reflects brand reputation rather than superior execution.
The Practical Bottom Line
Spending 4–6 hours collecting and comparing quotes typically reveals $1,500–$3,000 in savings and protects you from low-quality work. For concrete projects lasting 15–25 years, that investment pays for itself many times over.
