Thermal fogging your house after a fire is the only way to reduce the problem of the bad odour that lingers on both inside and outside the house after it has been gutted. First of all, you need to stop the air from entering your house as much as possible by keeping the doors and windows covered with such materials as plastic flaps.
Then you have to spray an air freshener (which is available in all the supermarkets and leading departmental stores) all over the house and buy pleated filters of a good quality for your furnace and change the pleated filters of your furnace on a regular basis, usually every couple of days. However, the actual process of thermal fogging or deodorising your house after a fire should only be done by a professional or a firm whose main activity is restoration and whose reputation in the market is good.
