You can call to check whether she do for timber. She did my floor marble polishing.

Looks like solid Oak timber flooring. If no oxidation or liquid damage, no need to do heavy sanding. Just light buffing with new matte coating will do.

Also, is the house occupied? If so, u will need a dust-free solution. Most contractors here used traditional dust everywhere system. After sanding, u may need a professional cleaner to clean everything.
