Privately owned and founded in the Midwest in 2011, Heritage Building Maintenance is based in central Iowa and serves commercial clients with the highest-quality cleaning and microbial protectant on the market today. Heritage goes the extra mile by using science to prove the efficacy of our system for use in office settings and medical and recreational facilities.

In 2022, Heritage was acquired by Bee-Clean Building Maintenance, Canada’s largest privately held janitorial company. While operations remained the same, this partnership opened the doors for continued growth and success in our industry.

Today, Heritage continues to be committed to making a difference in the health and productivity of our community and those we serve.

Core Values

01. Be Caring

Caring about people is the backbone of our organization. Caring is not just a feeling, but an action that has its focus on the best interest of others.

02. Communicate Honestly

Misunderstandings usually come from a lack of communication. Honest communication combined with caring is intended to strengthen our relationships, not force an opinion on someone else.

03. Make Our Work Joyful

We want our people to look forward to work and enjoy what they do. We can make our jobs joyful if we approach our work with a deliberate attitude of joy.

04. Be Disciplined Learners

The great thing about technology is that it challenges us to find better, more efficient ways to do things. Every day we look for opportunities to learn more and become better at maintaining a safe and healthy environment for the occupants of the buildings we are responsible for cleaning. We take learning very seriously.

05. Treat Property With Respect

Although we partner with our customers, when we are in their buildings, we are guests and we feel strongly that we should treat property with care. If by chance we do experience an incident performing our tasks, we make sure to let the customer know right away and take responsibility for rectifying the situation.

06. Strengthen Our Industry By Being Leaders

Doing our job properly has a direct health impact on the occupants of a building. We believe the contract cleaning industry should provide the first level of defense in healthcare. We want to be leaders in the industry by setting a standard of excellence through the development and implementation of new ways to clean for the health and well-being of people first and appearance will take care of itself.

07. Stay Humble and Be Grateful

It is so important to be grateful for all of life’s experiences, good or bad, for they all contribute to the development of our character and our efforts to become better people. We are reminded to remain humble and keep a proper perspective each day when we use one of our most essential tools in the successful completion of our work—the toilet bowl brush.
