Pinellas Point and Crescent Lake block ranches: plaster on block, terrazzo floors and 8-foot ceilings
South of downtown, Pinellas Point is 1950s through 1970s St. Petersburg: single-story concrete block under stucco, plaster skimmed straight onto the block in the older houses, drywall on furring strips in the later ones, terrazzo floors under a drop cloth. Crescent Lake mixes the same post-war block ranches in among its 1920s bungalows, so the installer taps the wall first. Plaster on block is the fastest masonry in the city: no gap, no furring, a 3/16-inch carbide bit straight through the skim coat into the CBS, 1/4-by-2-3/4-inch Tapcons aimed at the solid webs of the block, and a sleeve anchor for any hole that finds a hollow cell. Three anchors hold a 55-inch panel, four hold a 75. The ceilings sit at 8 feet, which puts screen center near 42 inches. The outlet in these houses is usually low and off to one side, so a flat power cord in a paint-matched raceway at $79 is the honest answer when the wall is bare block with no cavity to fish. Block means the +$99 masonry surcharge. A Pinellas Point ranch install runs 60-75 minutes.
