Lake Grove is a suburban village anchored by Smith Haven Mall, with a residential mix of ranches, splits, and colonials on tree-lined streets. It's a comfortable, established suburb with good access to shopping, the LIE, and Stony Brook.
For Lake Grove homeowners, we cover the full premium range — Samsung Frame TVs in the colonial living rooms, full Dolby Atmos home theaters with in-ceiling speakers in the basement media rooms, and clean multi-room installs across living room, family room, and primary bedroom. For larger homes, projector setups with motorized screens are very much in scope.
Drywall is the dominant wall type in Lake Grove's postwar and newer builds, with plaster in some of the older homes. We handle in-wall cable concealment on drywall, paintable raceway on plaster, and brick fireplace mounts with proper masonry anchors.
