Our Story

Sonnenburg Builders Inc. has been serving Manitowoc County since 1986.

Sonnenburg Builders

Owner, Brad Sonnenburg, reflects on Sonnenburg Builders Inc’s past, present, and future.

My father, Kevin Sonnenburg, started his career as a carpenter. When his boss was ready to retire, Kevin saw an opportunity to service our community.  He established Sonnenburg Builders Inc. in 1986. In the 80’s and 90’s he focused on building new homes. In 2000’s, he expanded the company to provide remodeling and addition services and continued to grow a reputation of building with a focus on quality and personalization.

Throughout my life, I had the opportunity to work along with my father and foster my passion for carpentry. After graduation, I continued to work with my father and fine-tuned my carpentry skills and knowledge. In 2021, I took over Sonnenburg Builders Inc. allowing the company to continue to service our community.


We pride ourselves on being involved throughout the building process and delivering our customers with a high-quality finished project. This principle is something we continue to focus on. It drives who we partner with from our subcontractors to our suppliers. Every detail of our customers projects is hand picked so we can continue to deliver high qualify craftmanship. Custom new homes is where our attention to detail and high quality craftmanship shines. Each home is uniquely designed and crafted with our customers, to bring their dream house to life.  To further service our customers we specialize in kitchen and bath remodeling, additions, siding, and window and door replacement.
