Only certain areas need regrouting
You can buy grout in a tube at Home Depot or Lowes which works great on wall tiles where the grout is missing. Red Devil is one brand and I believe DAP is another. Very easy to use for small areas. If you need to remove any loose pieces you can also buy a grout removal tool there.
Thank you very much. i'll let you know how it goes.
