More than a building. Your place in the world.

Custom Contracting delivers more than construction solutions. We help to create places where our clients can prosper. We’re expert at managing challenging projects ranging from complex technical environments to new out-of-the-ground construction. Our experience extends from healthcare and professional office spaces to retail and commercial projects. Every Custom Contracting project is managed on-site by seasoned professionals who find solutions and add value in even the most demanding environments and time-critical projects. We also offer considerable expertise in environmentally conscious construction and a deep understanding of regulatory compliance and best practices.

At Custom Contracting, we commit ourselves to you and your project goals—for the physical space you need and the human mission it supports. This is how we deliver on our full promise every time we build.
