Ask if the company documents every stage of their projects with a detailed plan showing the fixtures, accessories, and the wiring diagram that shows how the fixtures run together and where the wire is buried. Request for a sample of this type of documentation for previously completed projects. The company should be able to give you a copy of the documentation when your project is finally completed.

Documentation helps to troubleshoot any problems and make repairs without many difficulties. With the documentation, it is possible and easy for another company to work on your system. Avoid a company that cannot or does not provide documentation of projects.
