Not every tired-looking driveway needs to be torn out and replaced — sometimes a clean and reseal is genuinely all it needs. But some damage is a sign of a deeper problem that a surface treatment won’t fix. Here’s how to tell the difference before you spend money on the wrong fix.
Signs a Reseal or Repair Might Be Enough
- Surface staining or fading — oil stains, general wear and colour fading are cosmetic and usually don’t affect the concrete’s structural condition.
- Minor hairline cracking — small, stable surface cracks that aren’t widening or lifting are common in concrete and often just need sealing to stop water getting in.
- Surface pitting or minor scaling — can often be patched or resurfaced rather than requiring a full replacement.
Signs You Likely Need a Full Replacement
- Wide or widening cracks — especially cracks that have shifted or created a visible step between the two sides, which usually points to movement in the base beneath the slab.
- Sunken or uneven sections — a sign the base material has settled or washed out underneath, which resealing the surface won’t correct.
- Extensive spalling — large areas where the surface layer has flaked or broken away, exposing aggregate or reinforcement underneath.
- Persistent drainage problems — if water consistently pools on or flows toward the house, the driveway may not have been built with the correct falls in the first place.
- Age and known base issues — older driveways built without proper base preparation or reinforcement are more likely to have problems that resurface after a cosmetic fix.
Why the Base Matters More Than the Surface
Most driveway problems that come back after a “quick fix” trace back to the base, not the surface — a compacted crushed rock base and correctly sized reinforcement are what actually stop cracking and movement over time. A reseal treats the visible symptom; a proper base is what prevents the problem recurring.
