Water damage in any home is a pain, but when it gets into and under your carpeting, the problem just increased almost exponentially. Since all of the water present has to be removed in order to prevent long term problems and larger repair bills, the level of difficulty is considerably higher that what you would find if you only had to clean up a hardwood floor.
Because now, in addition to that hardwood floor, you have carpet and the padding beneath that supports it. Both of these materials can absorb a tremendous amount of water, water that may take a period of days to successfully remove. If the water removal is not complete and thorough, then you face the very real problem of mold, mildew, as well as structural problems and compromise that may adversely affect your home or business.
Can your carpet be saved? Yes, provided that it has been soaked for less than 72 hours, and if the water involved is not Category Three Water or Black Water, as this type of water is typically filled with sewage, viruses, parasites, and other dangerous elements.
Water will need to be removed from the carpet through the use of industrial strength pumps or wet dry vacuum units. The good nes is that this will remove most of the excess water from the carpet. The bad news is that your work has just begun. What little water or moisture remains will have to be removed via air circulation, using fans, blowers, and dehumidifiers to get rid of all the remaining moisture and humidity on surfaces and in the surrounding atmosphere.
Water beneath the carpet may only be accessible by taking up the carpet and properly treating the underside and flooring, while throwing away any water damaged carpet padding. The flooring, which may warp or crack due to water problems, will have to be dried, cleaned, disinfected, and sanitized, in many cases more than once to ensure complete drying. Always remember that any water trapped underneath the carpet may cause serious mold growth problems.
Carpets that are taken up should be laid flat and allowed to dry. Laying them flat is important, since any other configuration could result in the carpet having an incorrect fit when it is re installed.
