How to Avoid Common Mistakes When Hiring a Concrete Contractor

 Hiring the right concrete contractor in San Antonio can be the difference between a surface that lasts for years and one that cracks or sinks early. This guide covers the most common mistakes when hiring a concrete contractor and how to hire a concrete contractor with confidence, asking the right questions, obtaining permits, and comparing bids.

Why San Antonio Concrete Projects Need Extra Care

• Heat and humidity: High temperatures accelerate set times; improper curing leads to surface weakness and early concrete cracks. 
• Expansive clay soils: Clay expands when wet and contracts when dry, causing ground movement that stresses slabs, driveways, and patios.
• Sudden storms: Pop-up rains can wash finishes, cause pitting, and ruin pours without smart scheduling and protection.
• Permitting: City approvals and inspections are essential; skipping permits risks stop-work orders and re-pours.

A Local Cautionary Tale

A homeowner in Alamo Heights hired a low-cost crew that skipped permits. Mid-project, the city issued a stop order. The driveway had to be demolished and rebuilt, doubling the budget and adding weeks of delay.

The lesson: price without compliance, planning, and proof is a false economy.

Top Mistakes to Avoid When Hiring a Concrete Contractor

Avoiding the most common foundation mistakes when hiring a concrete contractor can mean the difference between a durable slab and costly repairs. Here are the top pitfalls to watch for and smarter steps to take.

1. Choosing the lowest bid without scope parity
   ●   Risk: Thinner slabs, poor base prep, missing rebar, and no curing plan.
   ●   Do this: Compare “apples to apples”—thickness, base, reinforcement, joints, mix, curing, drainage, cleanup, warranty.
2. Skipping license, insurance, and references
   ●   Risk: Liability exposure, no recourse on defects, poor workmanship.
   ●   Do this: Verify active insurance, ask for local references and recent project photos similar to yours.
   
3. No written contract or unclear definition of “done”
   ●   Risk: Disputes on timing, quality, and when the surface is ready for use.
   ●   Do this: Specify scope, materials, timeline, inspections, payment schedule, and warranty. Define “done” (e.g., poured and finished vs. cured and ready for foot/vehicle traffic).
4. Inadequate site prep for clay soils
   ●   Risk: Settlement, heaving, cracks, and uneven slabs.
   ●   Do this: Require proper subgrade prep, compaction, appropriate base, reinforcement plan (rebar size/spacing, fiber mesh), and joint layout.
5. Ignoring weather and curing plans
   ●  Risk: Surface scaling, dusting, pitting, and weak concrete.
   ●  Do this: Ask about early morning pours in summer, contingency for storms (covers, rescheduling), and curing method (e.g., curing compound, wet cure).
6. Unclear responsibility for permits and inspections
   ●  Risk: Fines, delays, demolitions.
   ●  Do this: Assign permit handling in writing and confirm timelines for inspections.
7. Not checking local experience
   ●  Risk: Generic builds that fail in San Antonio conditions.
   ●  Do this: Choose teams with proven local projects and familiarity with neighborhood drainage, soil behavior, and city requirements.

How to Compare Concrete Contractor Bids “Apples to Apples”

Tip: Don’t compare price alone, compare the scope and quality behind the price

Real San Antonio Pitfalls (And How to Prevent Them)

• The sidewalk that sank
  Cause: No rebar in a clay-heavy area; inadequate base.
  Symptom: One section dropped 2” within a year.
  Prevention: Proper compaction, adequate base depth, rebar grid, and joint layout matched to soil conditions.
• Washed finish after a pop-up storm
  Cause: No rain contingency or protection.
  Symptom: Pitted, uneven surface; aesthetic defects.
  Prevention: Weather monitoring, early morning pours, covers/tents, and willingness to reschedule.
• Early cracking on a new driveway
  Cause: Thin slab, poor control joint spacing, no curing plan.
  Symptom: Map cracking and random fractures.
  Prevention: 4”+ slab (project dependent), correct joint spacing, and curing compound or wet cure.

Timeline, Curing, and “Ready for Use”

• Define “done” in your contract:
  ○ Poured and finished vs cured and ready for use.
• Typical guidelines (project dependent):
  ○ Foot traffic: often 24–48 hours.
  ○ Light vehicles: often ~7 days.
  ○ Full strength: often ~28 days.
  
• Always confirm curing timeframes and access restrictions in writing.

How to Tell if Your Quote Is Fair

• Get at least three quotes with identical specs (thickness, base, rebar, joints, mix, curing, drainage, cleanup, warranty).
• If one is much lower, identify what’s missing.
• Evaluate total value: proven local work, warranty strength, and permit handling often save money long-term.
