What Makes Caithness Construction a Choice Builder?

All Caithness Construction homes are built with the highest of construction standards and designs that are above required Florida building codes. These practices are applied to every Caithness home regardless of size.


  • After the exterior concrete block wall is built, a horizontal solid concrete tie beam is formed and poured forming a stronger base for the triangular roof trusses.
  • During framing of the roof, heavier 2X6 top cord trusses are used for additional roof strength.
  • All outdoor lanais and portico ceilings are wire-lathed and stuccoed instead of dry-walled to maintain strength against outdoor elements and power-wash cleaning.
  • Top rated R-30 and R-19 insulation are used inside framed walls to optimize energy and enhance sound proofing of rooms, especially laundry and bathrooms.
  • Garage door openings are designed with a wider width for easier vehicle maneuverability. Also, wind resistant as well as hurricane rated garage doors are installed for protection and security.
  • All windows and glass doors are double insulated impact glass that meet hurricane requirements.
