How to Vet a Tampa Concrete Contractor — Checklist

Concrete is unforgiving: once it’s poured, the mistakes are buried. This checklist helps you separate real pros from pour-and-pray crews before the truck arrives.

Step 1 — Check registration and insurance

  1. Ask what registration the contractor holds in your county or city. (Florida has no state flatwork license — see our license guide.) Verify it with the county or city.
  2. For structural or commercial work, verify the Certified General Contractor license at myfloridalicense.com — Current/Active status, correct classification, matching business name.
  3. Get general liability and workers’ comp certificates from the insurer directly. Concrete work injures people; uninsured crews make their injuries your problem.
  4. Ask for two or three local references from the past 12 months — and actually call them. Ask: did they show up on schedule, was the final price the quoted price, and would you hire them again?

Step 2 — Ask the technical questions

These questions expose who understands Tampa conditions and who’s guessing:

  • What base material, what depth, and how compacted? Listen for specifics: crushed shell or limerock, 4+ inches, compacted in lifts. Vague answers mean vague base.
  • What thickness and what reinforcement? Four inches minimum for cars, five to six for heavy loads — plus rebar or wire mesh. “We pour it thick” isn’t an answer.
  • Where are the control and expansion joints? A pro can sketch the joint layout. No plan for joints means random cracks later.
  • How are you handling drainage and grading? Where does water go in a Tampa cloudburst — toward the street and yard drains, never toward the house or garage.
  • What mix are you pouring, and when? The PSI, and whether they schedule around Tampa’s afternoon heat and storms. Morning pours and proper curing matter here.
  • What’s the sealer, and when do I reseal? Brand, coats, and the reseal interval for Florida — plus what a reseal visit costs.
The two-minute test: ask about the base and the drainage in one breath. Contractors who light up and get specific are the ones whose driveways still look good in ten years. The ones who change the subject to price are telling you exactly where their attention is.

Step 3 — Compare bids on specs, not price

Get three bids and line them up on the same grid: thickness, base depth and material, reinforcement, joint plan, mix PSI, sealer, demo and haul-off included, permit included, drainage scope, warranty terms. Bids that can’t fill the grid aren’t comparable — ask for the missing specs in writing before you decide.

Step 4 — Get the contract right

  • Exact scope in writing: square footage, thickness, base, reinforcement, finish, sealer
  • Start and completion dates, with a weather contingency for hurricane season
  • Who pulls the permit — and that inspections will be passed before final payment
  • Payment tied to milestones; balance due on completion, not before
  • Workmanship warranty in writing: duration and what it covers (cracking beyond control joints, settling, spalling)
  • Cleanup and landscape restoration responsibility

Step 5 — Red flags: walk away

  • “Leftover concrete from another job” door-knocker discounts
  • No local registration, no insurance certificates, no references
  • Refuses to put thickness, base, or reinforcement in writing
  • Demands full payment upfront
  • Suggests skipping the permit
  • Quote far below the other two — in concrete, that discount comes out of your slab
  • Pressure tactics: “price is only good today”

Vetting FAQs

How many concrete bids should I get in Tampa?

Three is the standard. With concrete, the bids will spread widely because the differences hide in the base, thickness, and reinforcement — not in the concrete itself. Line up the specs side by side; the cheapest bid almost always achieves its price by skipping base prep or pouring thinner.

What's the most important question to ask a concrete contractor?

What base are you putting under this, and how are you compacting it? In Tampa's sandy soil, the base decides the slab's lifespan. A contractor who answers in specifics — material type, depth, compaction method — is a pro. One who waves it off is not.

Should I ever pay a concrete contractor upfront?

A modest deposit (typically 10–30%) is normal for residential work to cover materials and scheduling. Full payment upfront is not — tie the balance to completion and your satisfaction. On commercial jobs, use milestone-based payments with retainage.

Do I need my concrete contractor to pull a permit?

For driveway replacements touching the right-of-way, commercial work, and structural slabs — yes, and the contractor should handle it in their name. The permit triggers inspections, which is your quality control. Confirm permit responsibility in the contract before signing.
