The short answer
Find the Moisture Source
A musty smell is a sign that something is damp. Check common spots like carpets, drywall, baseboards, and under sinks. Look for water stains, warped wood, or peeling paint. If you had a recent leak or flood, the source could be hidden behind walls or under flooring.
Use your nose to trace the strongest odor. Feel walls and floors for cool, damp spots. If you suspect a hidden leak, a leak detection service can locate it without tearing things apart. In humid climates, moisture can linger in the air, so act quickly to prevent mold growth.
- Check under sinks and around toilets
- Inspect carpets and padding for dampness
- Look for water stains on ceilings and walls
- Feel baseboards and drywall for moisture
- Check crawl spaces and attics for leaks
Dry Out the Affected Area
Once you find the damp spot, dry it as soon as possible. Open windows and doors to increase airflow. Use fans to circulate air, and run a dehumidifier to pull moisture from the air. If the weather is humid, a dehumidifier works better than open windows.
Remove any wet items like rugs, cushions, or cardboard boxes. If drywall or insulation is soaked, you may need to cut it out and replace it. Drying can take days, so be patient. For large areas, structural drying and dehumidification equipment can speed up the process.
Clean and Neutralize Odors
After drying, clean surfaces to remove mold and mildew. Use a mix of water and white vinegar or a commercial mold cleaner. Scrub hard surfaces like tile and concrete. For fabrics, wash them with hot water and detergent if possible.
Baking soda can absorb lingering odors. Sprinkle it on carpets and let it sit for a few hours before vacuuming. Avoid masking the smell with air fresheners; they cover the odor but do not fix the cause. If the smell remains, the material may be permanently damaged and need replacement.
- Use vinegar or a mold cleaner on hard surfaces
- Wash fabrics in hot water with detergent
- Sprinkle baking soda on carpets, then vacuum
- Discard porous items that cannot be cleaned
- Run an air purifier with a HEPA filter
Prevent Future Musty Smells
Keep indoor humidity below 50 percent to discourage mold. Use exhaust fans in bathrooms and kitchens, and fix any leaks promptly. In a humid climate, a whole-house dehumidifier can help during the summer months.
Ensure good ventilation in closets and crawl spaces. Leave space between furniture and walls to allow air to move. Regularly check for signs of moisture, especially after heavy rain or storms. Early action stops small problems from becoming big ones.
When to Call the Pros
If the musty smell persists after thorough drying and cleaning, the moisture may be trapped in structural materials. Water can seep into wall cavities or under flooring where you cannot see it. In that case, a professional inspection can identify hidden moisture.
The pros use moisture meters and thermal imaging to find damp spots. They may also set up industrial dehumidifiers to dry out the structure. If you suspect a hidden leak, a pipe leak detection service can pinpoint the source. Acting quickly reduces the chance of mold spreading.

How long does it take to get rid of a musty smell?
It depends on the extent of the moisture and the materials affected. Small areas may dry in a few days with good airflow. Larger areas or soaked drywall can take a week or more. If the source is hidden, the smell may persist until it is found and dried.
Can a musty smell harm your health?
Musty odors often come from mold or mildew, which can trigger allergies or respiratory issues. Symptoms may include sneezing, coughing, or watery eyes. If you feel unwell, see a doctor. Removing the moisture and mold is the right way to protect your health.
Is it enough to just use air fresheners?
No, air fresheners only mask the odor temporarily. The underlying moisture and mold remain, and the smell will return. You need to find and dry the moisture source, clean affected surfaces, and control humidity. Only then will the musty smell go away for good.
