What's the difference between a hairline crack and a structural crack?
Hairline cracks are narrower than a credit card edge, run shallow, and usually appear in the first year or two as the slab cures and the soil settles. They're a cosmetic issue, not a structural one, and they fill cleanly. A structural crack is wider, often has vertical displacement (one side higher than the other), and signals movement underneath — soil settlement, frost heave, root pressure, or a failing base. Structural cracks need an inspection before we recommend a fix because the underlying cause has to be addressed, not just the visible damage.
How long does a concrete repair last?
A properly executed crack repair on a stable slab can hold for the remaining life of the concrete — often 15 to 25 years on a residential driveway or patio. A resurfacing overlay typically lasts 8 to 15 years before it needs attention again, depending on traffic, sun exposure, and whether it gets resealed on schedule. The biggest factor isn't the repair technique — it's whether the slab underneath is still moving. Stable slab, good prep, right material: the repair outlives the next homeowner.
Can repairs be colored or stained to match the existing concrete?
Yes, within limits. For crack repair we tint the filler to blend with the surrounding slab color, though the line will be visible up close because the filler is a different material. For resurfacing, an integral color or a topical stain can match — or deliberately contrast — the original. A small mock-up on an inconspicuous area is the honest way to set expectations before the full job, and we'll do that on request.
Do you warranty repair work?
We stand behind our workmanship. The exact terms depend on the scope — a crack repair on a slab we've inspected and confirmed stable carries a different warranty than a repair on a slab the homeowner already knew was moving. We'll spell out the warranty in writing on your estimate before any work starts. No vague "satisfaction guaranteed" language, no fine print after the fact.
How soon can I use the slab after a repair?
Walking traffic on a crack repair is usually fine within 24 hours. Vehicle traffic on a resurfaced driveway typically waits 5 to 7 days for full cure, depending on temperature. We'll give you specific timing for your job — Arizona heat actually speeds the cure, but it also raises the risk of surface cracking if the slab dries too fast, so we time pours and finishes accordingly.
How much does concrete repair cost in San Tan Valley?
Crack repair on a residential slab typically runs from a low-hundreds minimum service charge up to a few hundred dollars for a normal driveway or patio. Resurfacing is priced by square foot — substantially less than a full replacement, but the cost depends on the finish (broom, stamped, stained). The honest answer is that we can't quote without seeing the slab, so we offer free on-site estimates. Send a photo of the crack first and we can usually tell you whether a repair makes sense before we even drive out.
