Not every ugly slab needs a jackhammer, and not every 'quick fix' is worth doing. The decision comes down to what failed: the surface, the slab body, or the ground under it. Here is how to tell which one you are looking at.
Surface problems: resurface
Spalling, discoloration, and shallow scaling with the slab still flat and sound underneath are cosmetic failures. Overlays and resurfacing coats restore the top for a fraction of replacement, and on Tampa pool decks a cool-surface overlay is often an upgrade on the original.
Structural cracks: judge by width and offset
Hairlines are life; cracks you can fit a coin into, or where one side sits higher than the other, mean the slab body or base has failed. A few isolated cracks in an otherwise flat driveway can be repaired honestly — widespread random cracking means the slab is telling you its base was never right.
Settlement: the sand giveth
Sunken sections near the garage or where downspouts discharge are base washout — common in our sand, especially where drainage was an afterthought. Slab jacking (mud or foam) can float a sound sunken section back to grade; it cannot save a section that is both sunken and shattered.
The replacement math
Replace when damage is structural across most of the slab, when repairs would exceed roughly half of new-pour cost, or when you are changing the layout anyway. And fix the cause in the same mobilization — drainage, base compaction, tree roots — or the new slab inherits the old slab's disease.
A quick self-assessment
Flat but ugly: resurface. Sunken but sound: lift. Cracked everywhere or moving: replace, and fix the drainage in the same mobilization. Photos of the worst sections get you a real recommendation without waiting for the walk-through.
