First and foremost, shut off the main water line to your home. This should immediately stop any further damage. Try to identify the exact location of the leak. You may be able to find a water shut off valve that is closer to the damaged area and you could restore water to the rest of you home. Next, to help reduce potential mold damage, extract as much water as possible. DO NOT use a standard vacuum for water. A shop vac, sponges or rags are necessary. If area is carpeted, pull back carpet and pad. Try to get a strong air flow on both sides of the carpet. Call Champion Plumbing once you feel the damage is contained.
