In fact, it is this commitment that has been the cornerstone of our success. With over 30 years of industry experience and thousands of satisfied customers, we have worked hard to build a solid reputation. Creating lasting relationships with every customer is important to us in order to provide permanent solutions, not only today, but also in the future.

About the Owner 

Owner of DBS

Bonnie Sundberg

Bonnie Sundberg opened the doors to DBS in February of 2012 with the help of her husband and mentor Dave. She is a licensed contractor in both Minnesota and Wisconsin. The best part of owning this business is helping people by repairing their homes, making them more healthy, safe, and comfortable. Bonnie strongly believes in creating lasting relationships, with both her employees and customers, and strives for this excellence every day.

Bonnie grew up on a small hobby farm in Duluth, MN. Raised around family members in the construction industry, this field has been familiar territory for her from a young age. She has held many different job titles throughout her life, the most important one is being a mom. Outside of DBS, Bonnie enjoys spending time with her family, traveling, gardening, and outdoor activities.


A world where every family lives in a healthy, safe, and comfortable home!


Creating lasting "WOW "relationships with employees and customers, while providing permanent home performance solutions!


Commitment - Integrity - Respect - Teamwork - Positivity
