Deep Clean by an Elite Team



It takes a special team of cleaning experts to transform a newly completed construction site from dust and debris to move-in or showing condition. With over 35 years of experience owning, operating and consulting in the cleaning industry, Elite National Building Services has pioneered a specialization in post-construction cleaning service, applying best practices and green cleaning principles for a healthier environment.

We partner with general contractors and other commercial clients to ensure their hard work—and the hard work of every architect and subcontractor—shines with spotless integrity. Their success is our success.

Knowing that dedicated staff are the heart of our business, we provide thorough training and are committed to diversity and professional opportunity throughout all levels of our organization.

Elite National is a 100% woman-owned business.

Denise Ransom, Founder & Owner

Denise’s professional and personal history includes work in the media, business and advocacy. Her first cleaning services business, Ultra Janitorial Systems, based in Northern California, employed more than 200 employees and was honored as Oakland’s Small Business of the Year in 1990.

Returning to her roots in Columbus in 2013, Denise was awed by the construction activity taking place in the area and saw a niche opportunity that led to the establishment of Elite National Building Services. In its first five years, Elite National has provided services to iconic new buildings and renovations in Columbus, working with the largest general contractors in the nation.

As one of the founding members and a past Board of Directors president of The Central Ohio African American Chamber of Commerce, Denise has continued her love of small business advocacy and development. Denise has also been involved in several community activities in her South Side neighborhood. She works with United Way’s Leadership Academy Alumni Association and is a member of the South Central Commons Blockwatch as well as a graduate of the inaugural class of the South Side Leadership Academy. When she’s not hanging out with her Columbus family or old friends, she’s watching her favorite teams on TV with her cat, Hoyt.


We bring a sense of calm and control to the final, most stressful phase of the construction process: completion.
