1. Identify the source of the problem. This may require hiring a professional that deals with mold or a contractor, home inspector, or handy man.
2. Don't always opt for the cheapest remedy. Mold has a nasty way of coming back if it isn't completely removed. Even if you identify the source of the moisture, a small amount can still grow and flourish with just a little moisture to live on. A simple solution of bleach and water may remove it visually but it can come back if it is inside the wall or ceiling.
3. Don't be afraid to replace a whole section of ceiling or wall. It is good to go ahead if it is in a wall to remove the whole wall to make sure you can see exactly where all the mold is present. This requires having your windows open and lots of ventilation. You don't want to cause mold spores to be air born if you can help it.
4. Be prepared, you may have termites. Termites love moist wood. Sometimes termites are the reason for the mold in some homes. They get into a wall, the baseboards and studs become hollow and This allows for moisture to enter in via rainy days, etc. and before long what the termites don't destroy mold will.
5. Trust your nose. Your nose often times can smell damp, rotting and unfresh smells like mold very easily. Don't just chalk it up to normal. It is not normal for a room in your house to smell like a soggy old gym sock. Hire a home inspector or someone specializing in mold remediation and get it taken care of. If you're planning on putting your house on the market than this becomes especially important. Any mold that turns up during a home inspection will be a deal breaker.
