The short answer
Find the Moisture Source
A musty smell almost always means moisture is present somewhere. Check for visible water stains, damp carpet, or condensation on windows and pipes. Look in closets, behind furniture, and along baseboards for discoloration or soft spots.
If you don't find obvious moisture, the source might be hidden inside walls, under flooring, or in the attic or crawlspace. A leak from a pipe or roof can create dampness without being visible. You can use a moisture meter to check suspicious areas, or you can call local water damage pros who have tools to detect hidden moisture.
- Check for visible water stains or discoloration
- Feel walls and floors for dampness
- Inspect around windows, doors, and pipes
- Look in closets and under furniture
- Check the attic and basement for leaks
- Use a moisture meter if you have one
Clean and Dry the Area
Once you find the source, fix the leak if you can. For a small leak, you might be able to repair it yourself or call a plumber. For roof issues, a roofer can help. Then remove any wet materials like carpet, padding, or drywall that cannot be dried quickly.
Clean hard surfaces with a mixture of water and white vinegar or a mild detergent. Avoid bleach on porous surfaces. After cleaning, dry the area thoroughly using fans, a dehumidifier, or open windows if the weather allows. Keep the air moving for several days to ensure everything is fully dry.
Reduce Humidity in the Room
Even after the source is fixed, high humidity can keep the smell alive. Use a dehumidifier in the room, especially in basements or bathrooms. Aim for indoor humidity below 50 percent. You can buy a hygrometer to measure it.
Improve air circulation by opening doors and windows when possible, and use exhaust fans in kitchens and bathrooms. Avoid drying clothes indoors and fix any leaks in the plumbing or roof promptly. If you live in Rogers, keeping a dehumidifier running during humid months can help prevent musty odors from returning.
Use Odor Absorbers
After cleaning and drying, you can use odor absorbers to tackle lingering smells. Baking soda in open containers can absorb odors, as can activated charcoal products made for this purpose. Place them in the room for a few days and replace as needed.
You can also try a commercial odor neutralizer that is safe for the affected surfaces. Avoid using heavy air fresheners that only mask the smell. If the musty odor is strong or persistent, it may indicate mold growth, which requires professional attention for safe removal.
When to Call in the Pros
If you cannot find the moisture source or the smell persists after your efforts, it is time to call the pros. They use specialized equipment to detect hidden moisture and can dry out walls, floors, and structural cavities. They can also help with structural drying and dehumidification to prevent further damage.
If you suspect mold, a mold professional should assess the situation. Mold can cause health issues, so see a doctor if you feel unwell. The pros can also help with water extraction after a flood or major leak. Remember that insurance coverage varies, so check your policy to understand what is covered.

How long does it take to get rid of a musty smell?
It depends on the source and extent of the moisture. Small areas may dry in a few days with fans and a dehumidifier. If the moisture is inside walls or under flooring, it can take longer. If the smell persists, you may need professional help to locate and dry hidden moisture.
Can I use bleach to remove musty smells?
Bleach can help on hard, non-porous surfaces, but it is not effective on porous materials like drywall or wood. For those, use a vinegar solution or a mild detergent. Always test a small area first and ensure good ventilation. If mold is present, a mold professional should handle it.
Is a musty smell a sign of mold?
Not always, but it often indicates moisture that can lead to mold. A musty odor can come from damp materials, even without visible mold. If you see or smell mold, it is important to address it, as mold can affect indoor air quality. A mold professional can assess and safely remove it.
