Carrollton has a lot of guys with a mixer truck and a Facebook page. Some of them are good at this. Some of them poured a patio for a cousin last summer and decided it was a business. The hard part for a homeowner is that a bad slab and a good slab look almost identical the day it's poured. The difference shows up eighteen months later, when one has a crack running corner to corner and the other doesn't.

Here's what actually separates the two, and what to ask before you sign anything.

What licensing and insurance actually mean here

Texas doesn't require a statewide license to pour concrete, which is part of why the field is so crowded. That means the paperwork you should ask for isn't a state license number, it's a certificate of general liability insurance and, if they run a crew, workers' comp coverage. Ask for the certificate directly from the insurance company, not a screenshot. If a contractor won't produce one, that's your answer right there. A slab is heavy, wet concrete is caustic, and if someone gets hurt on your property without coverage, that liability can land on you.

Also ask how long they've been doing this specific work in this area, not just concrete in general. A guy who mostly pours flatwork in Fort Worth doesn't necessarily know how Carrollton clay behaves.

The ground matters more than the mix

Most of Carrollton sits on Eagle Ford and Austin Chalk clays, and a lot of yards have a layer of black gumbo topsoil over that. This soil is expansive. It swells when it's wet and shrinks hard when it dries out, and North Texas gives it plenty of both, a wet spring and a baked August. That movement is the number one reason driveways and patios crack, far more than the mix design.

A contractor who knows this will over-excavate soft or organic soil, compact the subgrade properly, and use a compacted base course, usually 4 to 6 inches of crushed limestone or road base, before any concrete goes down. Skipping that step to save a day of labor is the single most common shortcut in this trade. It's also invisible once the slab is poured, so ask directly: what are you doing to prep the base, and how many inches of base material are you using?

Older Carrollton neighborhoods, the ones built in the 1960s through 80s around Josey Lane, Perry Road, and the older sections near downtown, often have shallow tree roots, old irrigation lines, and sometimes old sidewalk or slab sections buried under a few inches of soil. Newer subdivisions out toward the Frisco and The Colony line have more consistent fill soil, but HOA rules on driveway color, sidewalk placement, and setbacks are more common there too. A contractor who's worked both knows to check for both problems before quoting a price.

Reading the actual quote

A one-line quote, "driveway, $X," tells you nothing. A quote worth trusting spells out:

  • Slab thickness. Standard for a driveway is 4 inches, but if it's going to see a lot of vehicle traffic or a heavier vehicle like an RV, 5 or 6 inches makes sense.
  • Reinforcement. Rebar (typically #3 rebar on 18 to 24 inch centers) holds a slab together far better than wire mesh, which tends to sag to the bottom of the pour and do almost nothing. Mesh is cheaper and still common. Ask which one you're getting and why.
  • PSI of the concrete mix. 3,000 PSI is fine for a sidewalk or patio. Driveways and anything holding real weight should be 3,500 to 4,000 PSI.
  • Joint layout. Control joints need to be cut within 24 to 48 hours of the pour, roughly every 8 to 10 feet for a driveway, so the slab cracks along that joint instead of wherever it feels like.
  • Cure time. You can usually walk on a new slab after 24 to 48 hours, drive a car on it after about 7 days, and it reaches most of its strength by 28 days. Anyone telling you to park a truck on it the next day either doesn't know better or doesn't care.

If a quote skips all of that and just gives you a square footage price, you're not comparing apples to apples against a quote that specifies everything above, even if the number looks lower.

Permits and how the city fits in

The City of Carrollton requires permits for most new concrete flatwork, driveways, patios, and definitely anything tied to a foundation. A legitimate contractor pulls that permit, or walks you through pulling it, and knows what the inspector will check, usually the base prep and reinforcement before the pour, sometimes a final check after. If a contractor tells you permits are a waste of time or money, that's a shortcut talking, not experience. Skipping the permit doesn't just risk a fine, it can cause problems later if you sell the house and a buyer's inspector flags unpermitted work.

If you're in an HOA, which covers a good share of the newer subdivisions in Carrollton, check whether they require approval on driveway extensions, stamped patterns, or color before work starts. Some contractors will handle that paperwork for you. Ask.

Red flags that mean you walk away

A few things should end the conversation fast:

  • Asking for full payment upfront, before any material is delivered. A deposit is normal. The whole amount is not.
  • No fixed address or a phone number that's the only way to reach the business.
  • Heavy pressure to sign today because "the price goes up tomorrow."
  • A quote well below everyone else's with no explanation. Concrete, rebar, and labor cost roughly what they cost. A price 30% under the next lowest bid is usually thinner slab, mesh instead of rebar, or no base prep at all.
  • Reluctance to give you the name of a past customer, even if it's just one, or to point you to a property they've actually worked on.

None of this is complicated once you know what to ask. It's just that most homeowners don't get a second concrete driveway in their lifetime, so nobody's had the chance to learn it the hard way before spending the money.

If you want a second opinion on a quote you've already got, or want to talk through what a job on your specific lot would actually need, that's the kind of thing we walk people through at Carrollton Concrete before anyone signs anything.
