I wrote a detailed review on Angie's list, so this one will be brief. I am so glad to have found Silver Olas! They are all incredibly hard working, professional, quality oriented, and customer service oriented. They sent a thank you note, and called to be sure we were pleased. It is so nice to feel valued as a customer. This is the third tile cleaning company I've used, and they are the best! We will be using them again, and for additional services.
