Quality Service

Working Right

We offer a wide range of services that are easily customized to meet the needs of our clients. Our goal is to provide a leading, competitive level of service and expertise that goes beyond your regular general contractor. At every step, we work to make the process of commercial general construction easy for our clients.

With services uniquely designed to simplify construction, we'll take care of everything.


We make sure you're set up for success.

You tell us your vision, and we’ll make it happen. We help clients get off to the right start with our Pre-Construction services.

We work closely with owners and design teams to examine all aspects of a project. Through pre-construction planning, we’re able to prepare an accurate budget and schedule.

We take care of everything.

With our design-build services, you tell us your vision, and we’ll take care of the rest.

Zellner’s design-build offerings make it possible for our clients to work with a single team for both the design and construction phases of their projects, leaving our clients free to focus on general scope and decision making.
