The decision between repairing and replacing a concrete driveway comes down to how deep the problem goes. Surface issues — hairline and moderate cracks, small spalled spots, stains, and minor settling — are almost always repairable with filling, patching, sealing, or slab leveling. Replacement becomes the right call when the damage is structural and widespread: cracks wider than a quarter inch across much of the slab, sections that have sunk or heaved several inches, crumbling that exposes aggregate over large areas, or a driveway that has simply reached the end of its 25-to-30-year life. This guide walks you through assessing your own driveway so you know which conversation to have.
What you'll need
- A tape measure
- A quarter or a screwdriver (to gauge crack width)
- A ball or marble (to check for slope)
- A notepad or phone camera
Recommended parts & supplies
- Concrete crack filler / sealant — if the verdict is repair — for the cracks
- Concrete patching compound — if the verdict is repair — for spalled and chipped spots
- Concrete driveway sealer — to protect a repaired driveway and extend its life

Step by step
- 1
Measure the width and pattern of the cracks
Walk the driveway and look at every crack. Hairline to roughly quarter-inch cracks, especially straight or isolated ones, are typically repairable with filler. Be concerned when cracks are wider than a quarter inch, spread in a spiderweb or map pattern across the whole slab, or have one side sitting higher than the other. Widespread, displaced cracking points toward replacement, not patching.
- 2
Check for sinking, settling, and heaving
Look for sections that have dropped below or lifted above the rest of the driveway. Set a ball or marble down and see if it rolls, and eyeball the slab against a straight edge like the garage threshold. Minor settling can often be corrected by slab leveling (mudjacking or foam). Severe sinking or a section heaved several inches usually means the base underneath has failed, which favors replacement.
- 3
Assess the surface condition and spalling
Examine how much of the surface is flaking, pitting, or crumbling. A few small spalled spots patch fine. But if large areas are flaking down to the aggregate, the whole surface is pockmarked, or the concrete crumbles when you poke it, the slab is deteriorating from within and resurfacing or replacement makes more sense than chasing individual patches.

Factor in the age of the driveway
A well-built concrete driveway lasts about 25 to 30 years in Houston. If yours is approaching or past that and showing multiple problems at once, repairs become a losing battle — you fix one area and another fails. A young driveway with isolated damage is almost always worth repairing; an old one with widespread damage is usually worth replacing.
- 5
Weigh the coverage and cost of repairs
Add up how much of the driveway is affected. A common rule of thumb: if repairs would cover more than roughly a quarter to a third of the surface, or if the cost of repairing everything approaches half the cost of a new driveway, replacement is the better long-term value. Patching a slab that is failing all over just delays the inevitable tear-out.

Decide and document for quotes
Photograph the cracks, sunken spots, and spalled areas, and note their sizes. If it is clearly surface-level, tackle the repairs yourself or get a repair quote. If you are seeing widespread structural damage, an aging slab, or major settling, get a professional assessment and a replacement quote. Bringing photos and measurements makes those quotes faster and more accurate.
When to call a pro
Get a concrete contractor involved whenever the assessment points past simple surface repairs. That means cracks wider than a quarter inch across much of the slab, sections that have sunk or heaved several inches, large areas crumbling to the aggregate, a driveway past its 25-to-30-year lifespan, or a big driveway where the damage is widespread. A pro can also tell you whether the underlying base and drainage — the real reason concrete fails in Houston's clay soil — need attention before any new concrete goes down, so you do not pay to replace a driveway that fails again for the same reason. When settling is the issue, ask specifically about slab leveling, which can save a driveway that looks like it needs replacing.
