Top 10 Questions to Ask Before Hiring a Concrete Contractor in Acworth
Hiring a concrete contractor in Acworth without the right questions is how homeowners end up with driveways that crack in five years, permit problems that surface at home sale, and contractors who’ve moved on by the time the warranty matters. The good news: qualified contractors in Cobb County answer all of these questions confidently and without hesitation. The ones who don’t are telling you something important.
In this post, we cover the ten essential questions every Acworth homeowner should ask before signing a concrete contract — along with what good and bad answers look like.

Why These Questions Matter in Acworth Specifically
The concrete contractor market in the northwest Atlanta metro — Acworth, Kennesaw, Woodstock, Marietta — includes a mix of established local contractors and lower-quality operators who work lower prices by cutting corners on preparation, licensing, and permitting. Cobb County’s red clay soil is unforgiving of inadequate subgrade work, and the consequences of a poor concrete installation here show up faster than in sandy-soil markets. Asking the right questions before contract signature is the most reliable way to distinguish between contractors.
Types of Questions: What to Ask and Why
Question 1: Are You Licensed in Georgia, and What Is Your License Number?
Georgia requires contractors doing work valued at $500 or more to hold a valid Contractor’s License. Ask for the license number — not just a yes — and verify it at the Georgia Secretary of State’s licensing portal. A legitimate contractor will provide this without hesitation.
Red flag: Hesitation, inability to provide the number immediately, or a claim that the project is “small enough” that licensing isn’t required.
Question 2: Do You Carry Liability Insurance and Workers’ Compensation?
Ask for certificates of insurance, not verbal assurances. The certificate should name your address as the certificate holder. Liability insurance (minimum $500,000) protects your property if the contractor damages it. Workers’ comp protects you if a worker is injured on your property — without it, the homeowner can be held liable.
Red flag: Any reluctance to provide actual certificates, verbal-only assurances, or a claim that workers’ comp isn’t required for “independent subcontractors.”
Question 3: Will You Pull All Required Permits for This Project?
Permitted work protects you at property sale and ensures the work has been inspected to code. For driveways, patios, and foundation work in Acworth, permits are typically required through the Cobb County Community Development Agency or the City of Acworth Building Department depending on your property’s jurisdiction.
Red flag: Any suggestion that permits aren’t required when you know they are, or that the homeowner should pull the permit for contractor-performed work.
Question 4: What Will You Do With the Sub-Base Before Pouring?
This is the question that separates contractors who understand Cobb County’s red clay soil from those who don’t. The correct answer for any concrete project in Acworth includes excavation to proper depth, a compacted gravel base (4–6 inches of #57 crushed stone for residential applications), and proper drainage grading away from the slab. Contractors who skip this step produce concrete that fails prematurely on our clay sub-grade.
Red flag: “We’ll prep and compact the existing soil.” Compacting native clay is not a substitute for a gravel base.
Question 5: What Reinforcement Will You Use?
The correct answer for Acworth’s clay-soil environment is rebar — typically #3 or #4 bar at 16–18 inch spacing for residential driveways and patios. Wire mesh is less effective on expansive clay because it often settles to the bottom of the slab during the pour, where it provides minimal tensile benefit.
Red flag: “Wire mesh” presented as standard without discussion of site conditions, or “fiber only” for large slabs on clay sub-base.
Question 6: Can I See Examples of Completed Projects in Acworth or Cobb County?
References from local projects that are at least 2–3 years old tell you how the contractor’s work performs over time under local conditions. Photos are helpful, but in-person references are more valuable — seeing the actual finished surface and talking to the homeowner about the contractor’s process and follow-through.
Red flag: References only from distant areas, only new installations, or inability to provide local references at all.
Question 7: What Is Included in Your Written Estimate?
A qualified concrete contractor provides a written estimate that itemizes: demolition (if applicable), excavation depth, sub-base specification and depth, concrete specification (PSI, mix design), reinforcement type and spacing, finish type, sealer (included or not), permit fees, and timeline. Any estimate that’s a single total without line items doesn’t give you the information you need to compare quotes intelligently.
Red flag: Verbal estimates, single-line estimates, or estimates that don’t distinguish between demo, base work, and the concrete pour itself.

Question 8: What Is Your Payment Schedule?
Industry standard for concrete work is 10–20% deposit at contract signing with the balance due upon project completion and your satisfaction. Any contractor requesting 50% or more upfront before work begins is outside normal terms and represents a financial risk.
Red flag: Large upfront payment requirements, cash-only requests, or refusal to put payment terms in writing.
Question 9: What Is Your Warranty on the Work?
Concrete is a structural material — most qualified contractors in Acworth offer 1–3 year warranties on workmanship (the installation process and decisions they made) distinct from material characteristics (concrete is a natural material that can crack). Understand specifically what is covered: cracking from clay-soil movement may or may not be warranted depending on sub-base preparation guarantees.
Red flag: No warranty, or a warranty that covers everything in vague terms without specifying what conditions void it.
Question 10: Who Will Actually Do the Work?
Some larger contractors subcontract residential concrete work. There’s nothing inherently wrong with this, but you want to know who is actually on-site, whether those workers are licensed and insured, and whether the estimator you’re speaking with will have any supervision presence during the pour. The crew that shows up should be bound by the same licensing and insurance standards as the company you contracted.
Red flag: Inability to answer who will be on-site, or significantly different crews than represented during the estimate.
Practical Uses: How to Use These Questions in Acworth
-
Initial phone call screening: Use questions 1, 2, and 3 to eliminate contractors who can’t provide licensing and insurance information immediately. This alone narrows the field significantly.
-
In-person estimate meeting: Use questions 4, 5, 6, and 7 during the site walk-through. These questions reveal whether the contractor knows Cobb County’s soil conditions and has the depth of knowledge to do the project correctly.
-
Contract review: Use questions 8, 9, and 10 when reviewing the written proposal. The answers to these should already be reflected in the contract — confirm they are before signing.
-
Reference calls: Ask previous customers whether the contractor’s sub-base preparation was visible to them, whether the job matched the written estimate, and whether they’ve had any issues in the 1–3 years since installation. These follow-up questions from homeowners in Kennesaw, Marietta, or Acworth neighborhoods are the best quality signal available.
How It Works: What a Good Answer Sounds Like
When you ask about sub-base preparation, a qualified contractor in Acworth says something like: “We’ll excavate to 10 inches, compact the native soil, then install 4–6 inches of #57 gravel base before forming. On Cobb County clay, the gravel base is non-negotiable.”
When you ask about permits, a qualified contractor says: “Yes, we pull permits for all applicable work. For a driveway in unincorporated Cobb County, that means a Cobb County Community Development permit. If you’re in the city limits, it may also involve City of Acworth review. We handle the application and inspection scheduling — you don’t have to do anything.”
Those specific, confident answers are what you’re listening for. Vague answers, deflection, or irritation at being asked are the signals that help you avoid a costly mistake.
Frequently Asked Questions
How do I verify a Georgia Contractor’s License?
Visit the Georgia Secretary of State’s professional licensing search tool and enter the contractor’s name or license number. A valid license will show the license type, status, and expiration date. For concrete work, look for a valid Residential-Basic Contractor license or higher.
How many estimates should I get for a concrete project in Acworth?
Get at least three written, itemized estimates for any project over $1,000. This is not about finding the lowest price — it’s about establishing a market baseline and identifying which contractors are including appropriate sub-base work in their scope. See our concrete driveway cost guide for Acworth for reference pricing to evaluate quotes against.
What if the lowest bidder has good reviews online?
Reviews capture the customer experience — responsiveness, cleanliness, professionalism. They rarely capture sub-base preparation quality or long-term durability, because those outcomes aren’t visible until years after installation. Weight recent reviews from homeowners who had their project completed 2–4 years ago more heavily than reviews from the same month the project was done.
