How to Stop Musty Smells in Closets, Bathrooms & Basements

Is it possible for a closet, bathroom, or basement to remain odourless after finding out the exact cause of that damp odour? 

Yes, it is possible through proper cleaning, improved air circulation, and some preventive measures. Damp odors are caused by moisture, poor ventilation, or even hidden mold and mildew. 

This blog is going to emphasize similar basic solutions: proper cleaning, drying the area, improving ventilation, and storing only dry items. 

What Causes That Musty Smell?

Mustiness in an area may be a clue that there is too much humidity in the air. Dampness may be trapped inside a closet through clothing or shoes, humidity may be left in a bathroom after taking a shower, and dampness may be collected in a basement from the walls, floor, or any leaks. When there is lingering dampness, odor may start to form inside fabrics, wood, grout, and even cardboard.

Fortunately, the odor can be treated if the source is taken care of and not the odor itself.

Freshen Up Closets

Since closets are relatively small and enclosed, they tend to become humid very quickly. First, remove all the items from the closet to inspect for any wet garments, wet shoes, cardboard boxes, or other objects that might be retaining moisture.

Clean all the shelves, vacuum the floor, and leave the closet doors open to air out the space. When placing items back into the closet, ensure that only dry and fresh items are stored there. For an added measure, place moisture absorbers or a dehumidifier near the closet.

One way to prevent moisture build-up is to avoid storing any sweaty garments, wet coats, or wet shoes in a closed closet.

Reset Bathrooms

The bathroom battles moisture all day long; hence, it requires more maintenance. Turn on your exhaust fan while taking a bath and immediately after to let out the moist air. Open the windows if you can, and dry off the damp surfaces in the bathroom such as the walls, sink, and shower corners so that there is no moisture left.

If the odor persists, check for any buildup of grout, soap scum, mildew, or any leakages in the area underneath the sink or behind the toilet bowl. Clean and dry these places thoroughly. Make sure that bath mats, shower curtains, and towels are cleaned regularly since they may harbor odor-causing bacteria.

Keeping the bathroom dry helps make it fresher.

Refresh Basements

The basement is a likely problem area because it tends to be cold, sealed up, and somewhat damp. Check for water intrusion through wall marks, peeling paint, condensation, or musty odor around stored items.

First, declutter and get rid of any wet or moldy things. Clean the floors and surfaces, and dehumidify the area to reduce moisture. Air circulation is important, too, so vent out or open the window as conditions permit.

For storing items in the basement, avoid using cardboard boxes and make sure that they do not touch the floor.

Simple Prevention Habits

The best thing to do to eliminate musty odor is to prevent moisture from accumulating again. This can be done by addressing leaks, making sure that wet things are dried before storage, and allowing proper ventilation inside enclosed spaces.

It is also helpful to ensure regular cleaning especially in places that tend to be neglected such as corners, behind furniture, under the sink, and near appliances. The appearance of musty odor after cleaning is an indication that the source is still present and needs to be addressed.

In other words, the three basic ingredients for a fresh-smelling home include proper ventilation, dryness, and cleanliness.

Final Thought

A musty odor will certainly give a house an older feel that does not necessarily reflect the age of the house. However, it is not difficult to solve this problem by identifying the source of moisture, cleaning the area thoroughly, drying it completely, and ensuring air circulation.
