Winter makes Pittsburgh concrete look worse than it is — and sometimes exactly as bad as it is. The replacement decision hangs on what failed: surface, structure, or the frost-heaved ground below. Each has a different answer.
Surface scaling: often saveable
Flaking and pitting from salt and freeze-thaw, with the slab still flat and solid, is a surface wound. Resurfacing overlays restore it for a fraction of replacement — provided the underlying concrete is sound and the scaling isn't announcing a bad original mix, which a pro can tell in one look.
Heaving and settlement: read the seasons
Sections that rise and fall with the calendar are riding frost lenses in wet clay — the fix is drainage plus lifting, not just new concrete over the same wet base. Sections that sank and stayed sunk can often be raised by mud- or foam-jacking at a third of replacement cost, if the concrete itself is intact.
Crack patterns tell the story
A few straight cracks at the joints: normal life, repairable. Random map-cracking across the surface, corners breaking loose, offsets you can trip on: the slab body or base has failed, and patches will be annual events. Widespread failure plus age plus a bad mix equals replacement.
Doing the math like a contractor
Repairs approaching half the cost of new work, on a slab past twenty winters, argue for replacement — this time with air-entrained mix, real base depth, and drainage designed for the hillside. That combination is why the replacement outlives the original by decades.
Deciding in daylight
Assess in late spring when winter's evidence is fresh but the ground has settled. Photos of offsets, crack patterns, and seasonal movement give any estimator what they need for an honest verdict — and spring booking beats the fall rush every year.
