I own a home that is over 25 years old and I believe the tile grout has never been cleaned. I had my doubts that it would be worth even trying to clean it. I contacted Dave at Grout Kleen because a neighbor had one of his trucks in their driveway a couple weeks ago and I thought I’d give it a go. She also gave me a ‘thumbs up’ on their work and I thought at that point it was a no brainer… Dave came out ONTIME to give me a more than fair(I thought) estimate, and we had our kitchen and one bathroom done. The gentleman that came to do the work was early and very professional and worked diligently and above all, «clean»!! No marks on baseboards, and virtually NO signs that he had been in my house… with the exception that our tile and grout looked NEW afterwards! Kudos to the folks at Grout Kleen! I would, and WILL highly recommend them to friends and neighbors.
