Jim of Tile Bright, Billerica, MA, claimed his cleaning service would bring my kitchen tile grout back to original color removing all dirt.I was then also having it sealed after cleaning.
Unfortunately, that was not the case. The job was spotty -- some grout was cleaner but quite a bit still dirty. When I enquired about this, I was told two things "grout must be stained" and "sealer still wet."
First, prior to the job I told him my grout was plain dirty, never stained anywhere. Second, after 24 hours of drying, no change in color of grout --still dirty looking.
I don't feel enough attention to each and every grout line was taken, just hit or miss. Now I have sealer over dirt. I just paid $350 for nothing.
