We have three main methods of carpet cleaning. We use Hot water extraction. Encapsulation and Host Dry Extraction. If you want encapsulation of Host Dry Extraction you need to mention it at the time you schedule so we can make sure to have the equipment on the truck the day of the cleaning. What Cleaning method we use depends on a lot of variables. Some of these would be, how soon after cleaning do you need to use the room in question. What type of carpet it is. How soiled is the carpet. Is this a wool area rug? Is it commercial carpet or residential? Hot water extraction is the cleaning method we use on most residential wall to wall carpets. This is done using large state of the art truck mounted cleaning equipment.
