I've used Silver Olas Carpet Tile Flood Cleaning for a number of years and have always been very satisfied with their product because they are people of great integrity who back their work--and my house is safe with them. Recently, they cleaned four rooms and a hallway. The cleaner who responded was a very nice young man who was on time and polite and thorough. When he's here, he is not here for small talk but to do the work.
