Concrete cost — what to expect and what to skip

What concrete work costs, and which of it you should not be paying for at all. Prices vary by region and by how much access the job needs. Where a job has a genuine do-it-yourself version we say so rather than quoting a number for it.

Quick answerConcrete work is priced mostly by what you can’t see: breaking out and hauling the old slab, preparing the base, the reinforcement, and access for the truck. The paid jobs on this site are lifting a settled slab, dealing with a spalling surface, and working around tree roots. Cleaning joints, fixing drainage, watching hairline cracks and reading a quote properly cost you little or nothing.

Two quotes for the same driveway can differ a lot, and usually it’s because one includes base work, reinforcement and a curing plan and the other leaves them out. Compare line by line, not just the total.

1What concrete work involves

  1. AssessmentWorking out whether the slab is sound and needs lifting, or is broken and needs replacing, and why it moved in the first place.
  2. Removal and baseBreaking out old concrete, hauling it away, and compacting a proper base. This is where shortcuts cause most later settling.
  3. Forms and reinforcementSetting forms, joints and the rebar or mesh. Once poured, none of this can be checked.
  4. Pour, finish and curePlacing and finishing the concrete, then keeping it moist or using a curing compound so it gains strength without cracking.

2What drives the price

Cost driverWhy it mattersWhat to ask
Area and thicknessMore concrete, more labor. Driveways carrying vehicles need more than a walk.What thickness is being poured, and why
Tear-out and haul-awayBreaking out and disposing of old concrete is heavy, slow work.Is removal and disposal included
Base preparationA poorly compacted base is the usual cause of later settling.What base material, how deep, how compacted
ReinforcementRebar or mesh holds cracked concrete together. It’s where cheap quotes get cheap.What is going in and at what spacing, in writing
AccessIf the truck can’t reach the forms, the concrete has to be pumped or wheeled.Does the price assume a pump
Finish and seasonDecorative finishes add labor. Hot or cold weather adds curing work.What is the curing plan on pour day
Lift versus replaceLifting a sound slab is usually cheaper than replacing it.Is the slab sound enough to lift

3Things you should not pay for

These are either do-it-yourself jobs or questions to settle before you sign. None of them should turn into a big invoice on their own.

4Do it yourself or hire a pro

Do it yourself

  • Cleaning out and resealing joints
  • Redirecting downspouts and regrading soil at the slab edges
  • Marking and watching hairline cracks
  • Checking a quote for reinforcement, base and curing details

Hire a pro

  • Lifting a sunken slab by mudjacking or foam
  • Removing and replacing broken or delaminating sections
  • Any new pour of a driveway or large slab
  • Work near tree roots, after the tree has been assessed
Need a slab lifted or replaced?

Talk to a local concrete contractor and ask for the base, reinforcement and curing plan in writing.

5Questions

Why are concrete quotes so different?

Usually because they include different things. One may include tear-out, a compacted base, reinforcement and curing; another may leave them out. Ask each contractor to list them.

Is lifting a slab worth it?

If the slab is in one sound piece, lifting by mudjacking or foam is usually cheaper than replacement. Fix the drainage that caused the settling, or it can happen again.

Should I pay to have hairline cracks repaired?

Not usually. Shrinkage cracks in the first year are normal and largely cosmetic. Pay attention if they widen, offset or open with the seasons.
