How to Choose a Concrete Contractor (7 Questions to Ask)

How to Choose a Concrete Contractor: 7 Essential Questions

Concrete is a permanent material. Once it's poured and cured, fixing mistakes is expensive — sometimes requiring full demolition and replacement. Choosing the right contractor is the single most important decision you'll make for any concrete project. This guide walks you through the seven questions that separate qualified professionals from contractors you should avoid.

Why Contractor Selection Matters So Much

Unlike many home improvement projects, concrete leaves almost no margin for error. The material cures whether you're happy with it or not. A poorly prepared sub-base causes cracking you can't undo. Improper finishing creates surface defects you'll look at for decades. Choosing the wrong contractor isn't just frustrating — it's financially painful.

Question 1: Are You Licensed and Insured?

This is non-negotiable. Any legitimate concrete contractor should carry:

• General liability insurance: Minimum $1 million per occurrence. This protects you if they damage your property or a neighbor's.
• Workers' compensation insurance: Protects you from liability if a worker is injured on your property. Without this, you could be sued by an injured worker.
• State contractor's license: Requirements vary by state, but a license demonstrates that the contractor has met basic competency and legal requirements.

Ask for a certificate of insurance showing you as an additional insured for the project. Reputable contractors provide this without hesitation. Browse verified licensed concrete contractors on ConcreteListings — all listed contractors have confirmed their licensing status.

Question 2: How Many Similar Projects Have You Completed?

Concrete is a broad trade. A contractor who does 50 driveways a year has very different expertise from one who mostly pours foundation walls or does decorative work. Make sure the contractor you're considering has substantial, recent experience with your specific project type. Ask:

• How many projects like mine have you done this year?
• Can I see photos of 2–3 completed projects similar to mine?
• Are any of your recent projects nearby that I could visit or drive by?

Question 3: Can I Have 3 References from Recent Customers?

References from 2–5 years ago are essentially useless — company quality, crew composition, and ownership can change dramatically. You want references from projects completed in the last 6–18 months. When you call them, ask:

• Did the crew show up on time and stay on schedule?
• Did the final cost match the quoted price?
• Were there any problems, and how were they handled?
• Are you happy with how the concrete looks and performs?
• Would you hire them again?

Question 4: What's Included in Your Quote?

Written quotes should specify in detail:

• Concrete dimensions, thickness, and PSI strength
• Sub-base preparation (type and depth of base material)
• Reinforcement type (mesh, rebar, fiber)
• Demolition/removal of existing material (if applicable)
• Finish type (broom, exposed aggregate, stamped, etc.)
• Sealing (included or not?)
• Control joint placement
• Payment schedule
• Timeline

Never accept a quote that's just a price per square foot with no specifications. Vague quotes allow contractors to cut corners and leave you with no recourse.

Question 5: Who Will Be Doing the Work?

Some contractors are essentially salespeople who subcontract all actual labor. This isn't always bad, but you should know who will physically be on your property. Ask:

• Are your workers employees or subcontractors?
• Will you personally be on-site during the pour?
• How experienced is your crew with this type of work?

For complex decorative work like stamping, the specific crew doing the work is critical — skills vary enormously person-to-person.

Question 6: What's Your Warranty?

Ask specifically what happens if the concrete cracks within 1 year. Contractors vary widely in their warranty terms. Some offer full replacement for structural failures; others offer nothing. Get warranty terms in writing in your contract. Industry standard for residential work is 1–2 years on labor and workmanship. Material warranties are separate and come from the concrete producer.

Note: concrete will develop hairline surface cracks over time as it cures — this is normal and not a defect. Structural cracking (separation, heaving, large cracks) within the warranty period should be covered.

Question 7: What Is Your Payment Structure?

Be cautious of contractors requiring large upfront payments. A reasonable payment structure is:

• 10–25% deposit upon signing the contract
• 50% due at the start of work or material delivery
• Balance due upon satisfactory completion

Never pay 100% upfront. Never pay the final payment until you're satisfied with the finished work. For large projects, consider a retention of 5–10% held for 30 days after completion to address any issues that appear during initial curing.

Red Flags to Watch For

• Unusually low bids (often mean cutting corners on prep work or materials)
• Pressure to sign immediately or lose a "special price"
• No physical business address
• Cash-only payment requirement
• Unwillingness to provide written contract or insurance certificates
• Unable to provide recent local references
