Sexton Photographics has been designing and building custom underwater housings since 1968. For many years it was a part-time business while employed at various jobs in biology and engineering. In 1995, the workload grew to demand full-time attention, and has been so since then.

The facility consists of a 150 square foot office and 1800 square foot shop. 

The office has an elaborate computer network with many safeguards including physical security, firewall, multiple anti-virus and anti-spyware applications, multiple levels of on-site and off-site backup, uninterruptable power supplies for every computer, broadband and dial-up connections, resulting in state-of-the-art security for company and client data.

Computer Aided Design (CAD) is done with Autodesk AutoCad, Mechanical Desktop, and Inventor. Computer Aided Manufacturing (CAM) is done with Pathtrace EdgeCam to create NC code for a CNC router. The CNC Router is controlled by WinCNC. All software (operating systems and applications) is fully licensed and kept up to date in versions and patches.

The shop has an extensive complement of tools for working plastics, wood, and metal. Many cutting tools, such as saw blades, router bits, and drill bits are specially ground for use with each of these materials. The area is divided into sections by task and by materials used. In the metalworking area, there are lathes, milling machine, grinders, band saw, tapping machine, presses, and precision measuring and layout tools. In the routing area, there are many routers set up with special bits for certain frequently repeated tasks. Nearby, are sanders and buffers for finishing plastics. There are a variety of normal woodworking tools, such as table, miter, and band saws, each equipped with blades optimized for plastics. There are areas for storing parts, customer-provided equipment, and work in process. Finally there are areas set aside for final assembly, inspection, and shipping.
