My kitchen tile floor has moldy looking and discolored grout, and is even chipping up in places. How can I replace the old grout between my tiles with a new different color grout? Is it easy to do or should I call for an estimate from a tile flooring expert?
Depending on how wide the grout lines are and the condition best to chisele them or if they are in decent shape, use grout clean and regrout where needed. Make sure you seal the grout after. Really though all grout gets dirty, stained.
