About Castle Cleaning – House & Commercial Cleaning in Austin, TX

Our owner, Stuart Osantowski, worked in Telecommunications for over 14 years. After tiring of working for somebody else, in an industry not doing so well in those times, Stuart decided to give up that career and get back into cleaning.

He originally started cleaning offices as a second job to earn extra income to put himself through college. He learned fast and efficient methods of getting the jobs done and doing them well and became so adept at cleaning that he trained two of his college buddies to be his assistants.

Today, Stuart believes strongly in having a good working relationship with his staff. His principle of success is: “In order to grow your company, you must take care of your staff – because they are the ones taking care of your customers.”

“As long as we continue to go above and beyond our customer expectations, we will keep our clients satisfied.”
