I am not sure what you are asking in your question. A little more information would be so helpful so we can help you to the fullest. Thank you.
Most installers put a metal strip over two adjoining floors to smooth it and a walker should be able to roll right over one. If you could have someone install one for you from a home improvement store it would certainly enable you to make a smooth transition on the floors.
