I recent bought a restaurant that has been neglected for decades. The grout line on the tile floors were in such bad shape I didn't think that any company would get them clean ever again. I hired Michael to do the job off of a recommendation and I couldn't be happier with the out come. He totally brought life back to the original grout and he also resealed it. If he can get results LIKE THIS off of a 30+ year old restaurant floor, I'm sure he's capable of doing much more!
