I was very pleased with TIGRO TILE & GROUT RESTORATION. I bought the 10 years old condo and tiles of the kitchen floor had old grease stuck to the grout, and I couldn't completly clean tiles of the the hi-traffic area. I was in the search of a contractor to get all the tiles replaced, but my budjet was tight. Friend of mine recomended "Tigro" and sure enough it was a great solution. Ramiro was very efficient and accomodating,- condo have a restriction on the time when can be done any work in the units, plus my work schedule. It all turned out to be a great solution and pleasant experience!
