What Causes Musty Smells?

Understanding what causes musty odors is the first step in getting rid of them. Musty smells are typically caused by excess moisture and poor air circulation, which create an ideal environment for mold and mildew growth. These fungi release tiny spores into the air, resulting in that unmistakable musty aroma.

Dampness: High humidity or water leaks increase moisture levels.
Poor Ventilation: Closed spaces trap moisture, encouraging mold and mildew.
Organic Materials: Carpets, fabrics, wood, and paper can absorb moisture and harbor mold.
Neglected Cleaning: Dirt and dust combine with moisture to feed mold spores.

Note: Musty odors can sometimes signal a serious mold problem that may affect your health, especially if you have allergies, asthma, or respiratory conditions.

How to Get Rid of Musty Smells: Step-by-Step Solutions

Ready to say goodbye to musty odors for good? Follow these expert-recommended steps to refresh your home and protect against future smells:

1. Identify and Remove the Source of Moisture

Moisture elimination is the cornerstone of musty smell removal. Without controlling humidity and leaks, any effort to mask odors will be temporary.

Inspect for Leaks: Check for leaky pipes, faucets, appliances, and rooftops. Promptly repair any water intrusion.
Check Basement and Crawl Spaces: These are common sources of persistent dampness. Ensure sump pumps and drains are functioning.
Address Window and Door Seals: Replace worn seals to keep out excess humidity from outside.

Tip: Use a moisture meter to detect hidden dampness in walls, floors, and carpets.

2. Improve Air Circulation

Good airflow is essential to preventing and removing musty odors. Stagnant air allows mold spores and moisture to accumulate.

Open Windows: Air your rooms regularly, especially after cleaning or showers.
Run Exhaust Fans: Use fans in bathrooms, kitchens, and laundry rooms to expel humid air.
Use Ceiling and Portable Fans: Keep air moving in problem areas. This also helps dry out damp spots.
Move Furniture Away from Walls: This ensures air can circulate fully throughout the room.

3. Invest in Dehumidifiers

Dehumidifiers are an effective tool to control humidity, especially in basements and other perpetually damp spaces. Keeping relative humidity below 60% will help say farewell to musty smells and discourage new mold growth.

Choose a model with automatic humidity control settings for hands-free operation.
Empty the reservoir regularly and clean the filter.
Consider a whole-home dehumidifier for persistent problems.

4. Deep Clean to Eliminate Odor Sources

Deep cleaning is a powerful way to remove hidden sources of musty odors.

Shampoo Carpets and Rugs: Carpets can retain smells for years. Use a carpet shampooer or hire professionals.
Steam Clean Upholstery: Sofas and chairs absorb moisture and odors--regular steam cleaning freshens them up.
Launder Curtains and Linens: Wash fabrics frequently and dry them thoroughly before replacing.
Wipe Down Walls and Hard Surfaces: Mold and mildew can grow on less obvious surfaces, including walls, ceilings, and shelving.
Empty and Clean Closets: Remove everything and air closets out. Clean all shelving thoroughly.

5. Use Natural Deodorizers

If you want to get rid of musty smells naturally, consider these effective, non-toxic options:

Baking Soda: Sprinkle baking soda on carpets and upholstery, let it sit, then vacuum.
Activated Charcoal: Place charcoal bags or containers in musty locations--they absorb odors fast.
White Vinegar: Fill bowls with vinegar or wipe down surfaces to neutralize smells.
Coffee Grounds: Fill an open container of fresh coffee grounds and leave it in the affected area for days.
Essential Oils: Use oils like tea tree, lavender, or eucalyptus to gently freshen air without chemicals.

Pro Tip: While natural deodorizers tackle odors, they work best after addressing moisture and mold issues first.

6. Discard or Clean Items Beyond Salvaging

Sometimes, musty odors persist because certain items--like old books, cardboard, or clothing--have absorbed moisture deeply or become moldy. In these cases, it's best to:

Throw away irreparably moldy materials.
Deep clean or sun-dry salvageable fabrics, cushions, and paper items.
Store belongings in sealed plastic bins rather than cardboard boxes.

Preventing Musty Odors from Returning

The key to a fresh, odor-free home is ongoing maintenance and moisture control. Follow these preventative steps to keep musty smells at bay:

Maintain consistent humidity levels (ideally 30-50%) using air conditioning and dehumidifiers.
Ventilate rooms regularly--especially after cooking, bathing, or laundry.
Clean up spills and leaks immediately; do not allow water to sit on surfaces.
Declutter storage areas--reduce the number of moisture-prone items in basements, attics, and closets.
Use moisture absorbers: Products like silica gel and DampRid can keep small spaces dry.
Inspect hidden areas, such as under sinks or around window frames, for signs of water damage or mold growth.

When to Call a Professional

If you notice persistent musty smells despite your best efforts, or visible mold covering more than a few square feet, it's time to call in the experts. Mold remediation professionals can:

Properly identify hidden moisture sources and leaks.
Conduct air sampling to check for dangerous mold spores.
Safely remove large mold colonies and restore affected areas.

Important: Never attempt to remove large areas of black mold yourself. This can be hazardous to your health.
