Building for Life

For over 30 years, Key Builders Construction has specialized in a wide variety of commercial builds, such as: banking, religious, retail, veterinary, healthcare, recreational, industrial, and arts.

Pre-Construction Management

During pre-construction, numerous important decisions are discussed and made. We work with clients to layout all the essential components of the project.

Design Build

Allowing for more innovation and collaboration on projects, the design-build method allows us to take each project all the way through, from concept to completion. 

General Contracting

We oversee the daily progress of each project, manage vendors and subcontractors, and communicate information to all involved parties throughout the entirety of the project.
