OMG, my home looks brand new. I had tried on my own to clean the grout with harsh chemicals which killed my hands, even with gloves. I have hired companies that use these big machines that supposedly clean your tile and grout, that are nothing more than swirling disks of dirty water which clean nothing, and you get charged $500 for nothing. My kitchen was the worst. There is heavy traffic, grease and spills that happen in the kitchen all the time. So of course, your grout in the kitchen wears it all. They applied their colored mixture (there are several shades to choose from) on the grout and MY KITCHEN LOOKS LIKE THEY JUST LAID THE NEW TILE!!! The guys that came from EPICLEAN were amazing young men who were respectful, efficient and just a joy to have in the house. They vacuumed my entire home and washed down the floors before applying their mixture and asked me to go around and check everything to make sure they had it all done to MY satisfaction. I tell you, it's worth every cent. And they gave 10-year warranty where they come and touch up your home for a fraction of the cost. Well, worth it!
