I've used Silver Olas Carpet Tile Flood Cleaning every year for at least four years. They are very professional and do a great job. The staff is wonderful. All the technicians and the office staff are very accommodating. If I ever have a problem with the cleaning, they come right back to rectify it without any question. I've recommend Silver Olas Carpet Tile Flood Cleaning on my neighborhood list group and I'll continue to use them myself.
