Schertz Concrete Contractor: 7 Questions Before You Hire
A concrete project in Schertz is a long-term investment — a properly installed driveway or patio should last 25–40 years. But the quality of that investment depends almost entirely on the contractor who installs it. With Guadalupe County’s expansive clay soils, City of Schertz permit requirements, and summer heat that compresses working windows, this market has specific demands that separate qualified local contractors from those who don’t know the area.
In this post, we cover the seven questions every Schertz homeowner should ask before hiring a concrete contractor, the local red flags specific to this market, and what distinguishes a contractor who actually knows Schertz from one who doesn’t.

Why Hiring Matters More in Schertz
Many markets have relatively forgiving soil conditions where an average concrete installation holds up for years. Schertz is not that market. The expansive clay soils in Guadalupe County punish inadequate base preparation reliably — homeowners across Riata, Kensington Ranch, and other Schertz neighborhoods have the cracked driveways to show for it. A contractor who doesn’t specifically address clay soil subgrade preparation in their scope is telling you something important about the quality of work you’ll receive.
The local permit requirement adds another filter: a contractor who skips Schertz’s building permit process for flatwork is either unaware of the requirement or willing to ignore it. Either case is a problem.
The 7 Questions to Ask
Question 1: Do you pull building permits for concrete flatwork in Schertz?
The City of Schertz requires building permits for driveways, sidewalks, approaches, and parking surfaces. Any contractor who says permits aren’t required for concrete flatwork in Schertz is wrong. Any contractor who knows they’re required but recommends skipping them is asking you to accept the legal and financial risk of unpermitted work. The correct answer is: “Yes, we submit the permit application, plan, and site survey, and we coordinate the pre-pour and final inspections.” Read more in our Schertz concrete permit guide.
Question 2: How do you approach clay soil subgrade preparation in Schertz?
This is the single most diagnostic question for concrete work in Guadalupe County. A knowledgeable contractor will talk about excavation depth, compacted aggregate base material (crushed limestone or Class A flexible base), mechanical compaction, and rebar reinforcement. An answer that mentions only “we prep the base” without specifics is a red flag. Ask for the base depth in inches and the aggregate material type — you should get specific numbers.
Question 3: Can I see proof of your general liability insurance and workers’ compensation?
Any legitimate contractor carries both. General liability protects your property; workers’ compensation protects you if a worker is injured on your project. Ask for certificates from the insurance carrier — not a verbal assurance. Contractors who balk at providing certificates are telling you they may not actually carry the coverage.
Question 4: What concrete PSI and slab thickness will you use?
Residential driveways in Schertz should be specified at 3,500–4,000 PSI with a minimum 4-inch slab thickness; 5 inches is recommended for clay soil conditions. Patios can be 4 inches with appropriate base prep. A contractor who doesn’t know the PSI spec they intend to pour is not managing specifications — which raises questions about what else they’re not tracking.
Question 5: How do you handle summer pours in Schertz’s heat?
July and August average highs of 95–97°F compress the concrete working window to around 90 minutes. Ask how the contractor manages this: dawn pour scheduling, retarder admixtures, wet curing, and crew size are the relevant answers. A contractor who treats summer concrete the same as October concrete is not adapting to local conditions.
Question 6: Can you provide three references from similar projects in Schertz, Cibolo, or Universal City in the past 12 months?
Local references in the same soil conditions are more valuable than references from other markets. Call the references and ask: Did the contractor pull permits? Was the price close to the estimate? Did the work hold up? Would you hire them again? A contractor with no local references or who can’t provide them quickly may be newer to this specific market.
Question 7: What does your written estimate include?
A legitimate estimate should specify: square footage, concrete PSI and thickness, base prep depth and material, reinforcement type (rebar size and spacing vs. fiber mesh), finish type, control joint method (tooled vs. saw-cut), sealer inclusion (if any), demo scope (if old concrete is being removed), timeline, payment schedule, and permit handling. An estimate that lists only a price per square foot without these details is incomparable to other bids — and often hides the scope reductions that explain a lower price.

Permit refusal: As noted above, this is a disqualifying red flag in Schertz. Unpermitted flatwork can affect your home sale, insurance coverage, and compliance status with the city.
Door-to-door solicitation with “leftover concrete”: A well-documented scam in Texas. Legitimate contractors don’t approach homeowners unsolicited with ready-mixed concrete that happens to be left over from a job down the street.
Large upfront payment required: A reasonable deposit is 10–20 percent. Requests for 50 percent or more upfront are a warning sign.
Verbal-only estimates: All legitimate concrete work in Schertz should be documented in writing before work begins. A contractor who refuses to put the scope in writing is creating conditions where you have no recourse if the work doesn’t match what was discussed.
Prices far below market: Standard broom-finish concrete driveways in Schertz run $7–$10 per square foot with proper base prep included. A quote at $4–$5 per square foot is typically skipping subgrade preparation, using undersized rebar or none, or planning a thinner slab than specified. The savings at bid time cost more in repairs within five years.
No verifiable local address: Contractors with only a P.O. box or no local address are difficult to reach if problems arise post-installation.

Frequently Asked Questions
How many estimates should I get for a concrete project in Schertz?
Get at least three written estimates with comparable scope. Two estimates lets you spot a significant outlier; three gives you a better picture of the market range. Ensure the estimates include the same scope — base prep depth, rebar spec, and slab thickness should match before you compare prices.
Should I hire a contractor from Schertz specifically, or is any San Antonio contractor fine?
Contractors who regularly work in Schertz and Guadalupe County are more familiar with local permit requirements and clay soil conditions than those who primarily work in Bexar County. Contractors serving Cibolo, Universal City, and New Braunfels alongside Schertz typically have the right local knowledge. Ask about recent projects specifically in Guadalupe County.
How do I verify a contractor’s license in Texas?
Texas does not require a state contractor license for concrete flatwork specifically — unlike Florida, where state licensing is required. However, your contractor should carry appropriate insurance and should be familiar with and willing to comply with local permit requirements. Focus on insurance verification and references rather than state licensing for concrete contractors in Texas.
