The owner who is also a U.S. Marine came out with an assistant and they did a great job. I have cream travertine throughout my house (except the bedrooms). I bought this house a few months ago and have never been able to get the floors clean. I had no idea until today they are light cream not medium beige. There is hardly a smell at all, just a little noise (similar to a vacuum). The floors were cleaned and sealed in about an hour. Support our men of service! Use Valleywide stone care. My only beef is he doesn't accept credit cards. Get the square reader and take the card..
