Handicap Accessibility and Senior Living at Home: Home remodeling plays a key role for many seniors aging in place or handicapped persons needing to live comfortably at home. The reason is that homes generally are not senior-friendly or do not have Universal Design incorporated into the home to make it easy to live in and use. Remodeling lets a person create the home they need. We can specifically tailor your bathroom and kitchen to accommodate convenience. Door way can be wider for ease of access.
