A cracked, spalled, or worn slab usually doesn't need demolition — it needs the right overlay on properly prepared concrete. Here is what to verify before anyone quotes your driveway, garage, or patio.
Surface damage — hairline cracks, spalling, worn finish, stains — resurfaces beautifully at a fraction of replacement cost. Structural problems — deep cracks that move, settlement, heaving — come back through any overlay within a season. The whole game is diagnosing which one you have before money is spent, and then preparing the surface so the new layer actually bonds.

Hairline cracking and spalling are resurfacing candidates. Cracks that offset in height, slabs that rock, or sections that have settled need repair or replacement first. The assessment should name which category your slab is in — and why.
Overlays bond to clean, profiled concrete — which means grinding or abrading, crack routing and filling, and moisture checks before anything is poured. Prep is most of the job; it belongs in the written scope.
Polymer overlay, microtopping, stamped overlay, epoxy coating, or diamond polishing — each fits a different slab and use. The quote should name the product system and thickness, not just say "coating."
Foot traffic, car traffic, and full cure are different milestones measured in days apart. Get the timeline — and the weather window it depends on — before demo day, so your driveway isn't a surprise campout.
Get these checks as a one-page PDF you can hold any contractor to — sent the moment you request an assessment.
Get the Checklist →A reliable resurfacing estimate is specific about the crack assessment, the prep, and the system. Watch for these gaps.
Resurfacing over moving cracks prints them straight back through the new surface.
Bond failures start at skipped grinding and cleaning. If prep isn't written down, it isn't priced in.
"We'll put a coating on it" without a product and thickness leaves the lifespan of the job unwritten.
An accurate resurfacing price starts with knowing what the slab needs — which is why the process opens with your photos and a surface-vs-structural assessment, not a per-square-foot guess.
Driveway, garage floor, patio, walkway, or interior slab — and what's wrong: cracks, spalling, wear, stains.
Photos of the damage — especially any cracks up close — help the team read surface vs structural early.

If the cracks are hairline and the slab is stable, resurfacing restores it at a fraction of replacement cost. Cracks with height offset, rocking sections, or settlement point to structural movement that an overlay cannot fix — those need repair or replacement first.
Square footage, how much crack repair and grinding the prep needs, the system you choose (basic overlay vs stamped or decorative vs epoxy vs polish), and access. The prep scope moves the number more than the finish does.
Most overlay systems take foot traffic within a day or two and vehicle traffic within about a week, with full cure taking longer — exact times depend on the system and the weather. The timeline belongs in your written scope.
