How do I find a good concrete contractor?

Start with personal referrals from neighbors, friends, or family. Supplement with online searches (Google, Yelp, Angi). Get 3-5 quotes, verify licenses and insurance, check references, and trust your gut. A good contractor communicates clearly, shows up on time, and answers questions directly.

How much should I pay upfront for concrete work?

According to SlabCalc.co, a concrete contractor deposit should be 10–30% of the total project cost at contract signing, and you should never pay more than 30% upfront. Typically 10-30% as a deposit when signing the contract. Never pay more than 30% upfront—this protects you if the contractor disappears or doesn't perform. The balance should be due upon satisfactory completion. Avoid contractors demanding 50%+ upfront.

Should a concrete contractor be licensed?

Yes, in states that require licenses for concrete work (most do). A license indicates they've met minimum standards and carry proper insurance. An unlicensed contractor leaves you exposed: no recourse through the licensing board, and their work may not meet code.

What if my contractor does poor work?

Document everything with photos. Withhold final payment until issues are resolved. Request corrections in writing with a deadline. If they won't fix problems, file a complaint with the state contractor licensing board, Better Business Bureau, or consider small claims court for smaller amounts.

How to Hire a Concrete Contractor (Step-by-Step)

Before you start searching, decide whether to DIY or hire based on project complexity and your skills.

Step 1: Find Candidates (Get 3-5 Names)

Where to Look

Source	Pros	Cons
Personal referrals	Most reliable; real experience	Limited pool
Nextdoor/local groups	Neighbors' real feedback	Quality varies
Google/Yelp	Large selection; reviews	Reviews can be gamed
Angi/HomeAdvisor	Pre-screened (somewhat)	Contractors pay to be listed
Supplier referrals	Know who does quality work	May have relationships

Best approach: Start with personal referrals, then supplement with online searches for more options.

First Contact

Call or email with:

Brief project description
Approximate dimensions
Your timeline
Request for a quote/estimate

Red flag: Can't reach them or takes a week to respond.

Step 2: Verify Credentials

Before inviting anyone to bid, verify they're legitimate:

Contractor's License

What to Check	How to Check
License number is valid	State contractor board website
License is current (not expired)	Same website
License type covers concrete work	License categories
No disciplinary actions	Board complaint records

Note: Not all states require concrete contractor licenses. Know your state's requirements.

Insurance

Coverage	Why You Need It
General liability	Covers property damage
Workers' compensation	Covers worker injuries on your property

How to verify: Ask for certificate of insurance. Call the insurance company to confirm it's active.

Why this matters: If an uninsured worker is injured on your property, YOU could be liable.

Business Legitimacy

Physical address: Not just a PO Box
Years in business: Under 2 years is higher risk
Business registration: Verify with your state

Step 3: Get Quotes (3-5 Minimum)

What a Good Quote Includes

Item	Why It Matters
Detailed scope of work	Know exactly what's included
Dimensions and thickness	Verify they match your expectations
Concrete specs (PSI, type)	Quality indicator
Base preparation details	Often skimped on
Reinforcement details	Rebar or mesh specs
Site preparation	Who handles demo, clearing?
Permits and inspections	Who handles and pays?
Timeline	Start and completion dates
Payment schedule	When payments are due
Warranty	What's covered, for how long

Comparing Quotes

Quotes should be comparable in scope. If one is significantly cheaper, find out why:

Less concrete thickness?
Skipping gravel base?
No reinforcement?
Leaving you to handle permits?

The lowest bid isn't always best. Understand what you're getting.

Price Expectations

Use our concrete cost calculator to estimate fair pricing. Typical ranges:

Project	Typical Range
Driveway (600 sqft)	$4,800-9,000
Patio (200 sqft)	$1,600-4,000
Sidewalk (100 sqft)	$800-1,500

Step 4: Check References

Ask for 3-5 recent references (similar project type).

Questions to ask references:

How was the quality of work?
Did they stay on schedule?
Any surprises with the final bill?
How did they handle problems?
Would you hire them again?

Go see the work if possible. Drive by completed projects.

Online Reviews

Check Google, Yelp, BBB, Angi
Look for patterns, not just ratings
Read negative reviews carefully—how did they respond?
Be skeptical of all 5-star reviews (may be fake)

Step 5: Contract Essentials

Never start work without a written contract. Verbal agreements are worthless when disputes arise.

Must-Have Contract Items

Item	Details
Full scope of work	Everything they'll do
Materials specified	Concrete PSI, thickness, reinforcement
Total price	Fixed price preferred
Payment schedule	Tied to milestones
Start and completion dates	With buffer for weather
Permit responsibility	Who pulls and pays
Cleanup and disposal	Who handles
Warranty terms	Length and coverage
Change order process	How changes are priced
Cancellation terms	Both parties
Insurance certificates	Attached or referenced

Red Flags in Contracts

Vague scope ("concrete work as discussed")
No warranty mentioned
Large upfront payment required
Missing permits section
No timeline

Step 6: Payment Structure

Standard Payment Schedule

Milestone	Typical Amount
Contract signing	10-30% deposit
Materials delivered	0-25% (optional)
Work completed	Balance (40-60%)

Payment Red Flags

50%+ upfront: Major red flag. Too much leverage for contractor to disappear.
Cash only: No paper trail. Possible tax evasion.
Asking for final payment before completion: Never pay until satisfied.

Protect yourself: Consider paying with credit card for recourse options.

Red Flags to Avoid

Major Red Flags (Walk Away)

No license or won't provide number
No insurance or won't provide certificate
Demands cash payment only
Wants 50%+ upfront
Won't provide written contract
Won't pull permits ("to save you money")
Pressure to decide immediately
No physical business address
Can't provide references

Yellow Flags (Proceed with Caution)

Very new business (<2 years)
Price significantly lower than others
Communication delays
Vague answers to specific questions
Subcontracts everything

If Something Goes Wrong

During the Project

Document everything: Photos, dates, conversations
Communicate in writing: Email creates a record
Reference the contract: Point to specific terms
Escalate gradually: Conversation → written demand → legal

After Completion

Don't make final payment until issues are resolved
Document defects with photos and descriptions
Request correction in writing with deadline
File complaint with contractor board if unresolved
Consider mediation before litigation
Small claims court for smaller amounts

State contractor licensing board (complaints)
Better Business Bureau (complaints)
