My house was filthy after my mother in law stayed with us for a few days. She's a heavy smoker, and doesn't see anything wrong with smoking indoors. Our guest room reeked of cigarettes when she left, and there were ashes, butts, and even some some damage on the walls. I couldn't go in there without gagging, but it HAD to be cleaned up. So I called Flood Control. Let me tell you, you CANNOT beat a professional cleaning company! They were so good to clean and restore the room from both the smell, the air quality, and the smoke damage. Highly recommended!
