Wood-frame infill in Largo: stud-finder work, open bays and full-motion arms
The newer infill around Largo, houses built on leftover lots and teardowns, is drywall on wood frame, and it is the quickest TV wall in the city. A stud finder works on it: 2x4 studs on 16-inch centers behind 1/2-inch drywall, and a 1/8-inch pilot through each mark confirms the stud before the 5/16-inch lag bolts go in. This is the wall for a full-motion arm. An arm loads its top lags hardest when the screen is pulled out and turned, so the plate crosses two studs with four lags, the arm's tension gets set for the TV's weight, and the swing is tested empty before the panel hangs. Exterior walls in infill houses are insulated, so the cleanest concealment path is usually an interior partition, where an empty stud bay lets the cables drop straight to a brush plate near the outlet for the $99 in-wall rate. The bay still gets probed for blocking before any cut. Wood frame carries no masonry surcharge. Bedroom sets in these houses go at 42-50 inches to center. Infill installs run 45-70 minutes, a little longer with an arm.
