What does a concrete pool deck cost on Siesta Key?
About $9 to $14 per square foot for a new textured deck plus 5 to 15 percent for island logistics, so a 600-square-foot deck runs roughly $5,700 to $9,700 before demolition and drains; a basic overlay on a slab that passed the six tests is $4 to $8 per square foot. On the island the question before price is whether concrete is the right deck at all.

What's different about pool decks in Siesta Key
Concrete pool decks on Siesta Key make sense in three cases: an engineered slab under an elevated home in a VE zone, where the engineer designs it; a lanai on the interior of the island in AE where the slab drains and the owner wants a single surface; and a sound existing deck that passed sounding after 2024 and gets a light overlay. Where surge reaches, pavers win. Every pour here uses a low water-cement mix, 2 inches of cover over steel, a 7-day cure and a penetrating sealer.
Old cool-deck overlays from the 1990s are at end of life across the island; most fail sounding after two surges.
Rules that apply here
County permit (rules); deck is site work outside the 50 percent count; VE-zone slabs under elevated homes are engineered; setback variance for Gulf-front decks seaward of the line; turtle lighting.
A worked example
A 2019 elevated home on the interior of the key with an engineered 4-inch slab under the house and a 400-square-foot lanai deck that ponded against the cage. Scope: the slab stayed (engineer's design, sound), a linear drain was cut in at the cage low side, the deck was ground, bond-coated and given a light knockdown overlay with a matte grit sealer, cage anchors reset. County reviewed it as flatwork. Cost band: $3,200 to $5,000.
Can a Siesta Key deck that stood in surge be resurfaced?
Only after sounding shows no voids and a level shows it didn't drop; then a fresh-water rinse, a dry month, and an overlay. If it sounds hollow anywhere, the base under it moved and the overlay would follow.
