Attic Mold

The attic is an area that can be overlooked and not carefully kept dry. Check and make sure that there is proper ventilation and insulation in this area to discourage mold growth. Sometimes vents can get blocked by insulation or other items stored in the space.

Bathroom Mold

The bathroom is an area with lots of water usage and sometimes very little ventilation. Some problem areas for mold growth can be tile walls and flooring, grout along the tub or floor, and near windows. You also want to keep a close eye around and under the sink as well as plumbing fixtures in the shower. If areas do not dry quickly after use or if there are unexpected leaks, then mold is likely to form.

Steam from a shower introduces a lot of moisture into the room as you can see by looking at the mirror afterward. When the shower is complete, you will want to ventilate the bathroom as soon as possible. You can do this by opening a window, turning on the bathroom fan, or if do not have either, bringing in a fan or dehumidifier.


HVAC systems are vulnerable to mold growth since they are what transfers the different temperature air throughout a building to warm it or cool it, which often results in condensation forming on the HVAC surface. Even though it is unlikely for mold to grow on metal on its own, all mold needs is a little dust or dirt collecting on the HVAC surface for it to grow on.

What is particularly alarming about mold growing in HVAC systems is the fact that the system itself will then spread the spores throughout the home and potentially spread the problem to other rooms. Check the conditioning coils and the HVAC filter regularly to monitor any potential mold issues.

Laundry Room Mold

Just as with the large appliances in the kitchen, the washing machine and dryer in the laundry room are potential targets for mold growth. Keep an eye on the drainage system and try to keep the room well ventilated.

Crawl Spaces

Crawl spaces are havens for humidity and moisture, and they typically do not have proper ventilation or insulation. They are often overlooked and not monitored, which is a recipe for a mold disaster. If a crawl space has exposed dirt floors, then those should be sealed with a vapor barrier to better protect against mold growth. Check any pipes and ductwork running through these spaces to see if there is condensation forming.
