We just had our grout cleaned & sealed by Dirty Grout, and they did an exceptional job. The grout on our tile floors was so bad, I was embarrassed to have people in our home. We’ve only been in the home two years, but judging by the condition of the grout when we purchased it, I have to believe the previous owners had never had the grout cleaned. It was BAD. We tried several DIY methods with mixed results, but with 2,700-sq. ft. of house — most of it tiled — the job was just too big to do ourselves. A neighbor recommended Dirty Grout to us, so we called for an estimate. Tom, the owner, came & quoted what we found to be a VERY reasonable price. His team showed up precisely when he said they would, they were courteous & professional, and they even took care of a few extra little things for us at no additional charge. And at the end of the day, we were left with like-new looking grout. I am so, so pleased with the work they did & so, so upset with myself for waiting so long to have it done.
