improper specified underlay improper installation improper removal of taxes
trip improper floating of carpet excessive wear pet damage
hygroscopic materials gain and lose moisture continually in an effort
to equalize with the water content in the surrounding air mass the

damage especially when the air is allowed to remain above
60% relative humidity
abide by local laws and regulations when disposing extracted water
ways water is best disposed of into a sanitary sewer
the primary goal of the initial extraction of the affected area is to
