"proper" system design is the key to a successful and profitable installation. we specialize in producing system designs that can be installed with minimal material re-fabrication.

Our groundbreaking and breathtaking designs can be found in homes and offices around the world

When we design, we take the requirements of the systems installation into account. we "build" the system on the computer taking into account structural members, hanger points and other building mechanical systems. decades of experience in fire protection contracting gives us the experience required to create accurate piping layouts.

Our Mission

To provide the most cost effective sprinkler systems design service possible by creating accurate, comprehensive piping systems in consultation with our clients.


We take the time required to make sure the design will conform with the way it was bid and the installation crew will have all of the information necessary to complete the installation. These are the design philosophies that lead to the creation of Crown Fire Systems Design:

  • Always take the time to layout the system to minimize the effort to complete the installation. Taking into account he materials, the location, and the client.
  • Never forget why you're designing in the first place
  • Take pride in the final product and OWN it!
