A musty smell in the basement is a common problem faced by homeowners. Not only is it unpleasant, but it can also be a sign of underlying issues such as moisture, mold, or poor ventilation. If you are searching for how to get rid of musty smell in basement naturally, fast, or after a flood, you are in the right place. This comprehensive guide will help you understand the causes of musty odors and give you actionable steps to eliminate them effectively.
Why Does My Basement Smell Musty?
Before jumping into solutions, it’s important to understand why your basement smells musty in the first place. Knowing the root cause can help you target the problem directly and prevent it from coming back.
Even if your basement is dry but still smells musty, the odor may result from hidden moisture issues, poor air circulation, trapped humidity, or hidden mold growth.
Common Causes of Musty Basement Smells:
- Moisture trapped in walls, floors, and ceilings
- Leaks from plumbing pipes, walls, or foundations
- Poor airflow or lack of ventilation
- Stored items like cardboard, clothes, or old furniture absorbing moisture
- Mold and mildew growth behind walls or under carpets
- High humidity levels in the air
According to the Environmental Protection Agency (EPA), mold and mildew thrive in damp environments like basements, and often go undetected until the smell becomes obvious.
How to Get Rid of Musty Smell in Basement Naturally
If you prefer natural solutions and want to avoid harsh chemicals, here are effective methods to get rid of musty smells in your basement using items you may already have at home.
1. Increase Air Circulation and Ventilation
One of the simplest and most effective solutions is to improve the airflow in your basement. Stagnant air allows moisture and odors to linger. Open windows and doors when possible, and use fans to keep the air moving. Installing exhaust fans or air vents can dramatically reduce musty smells.
If your basement has no windows or poor natural ventilation, consider using mechanical ventilation systems to introduce fresh air and expel damp air.
2. Vinegar to Remove Musty Smell from Basement
White vinegar is one of the most powerful natural cleaners and deodorizers. To use vinegar to tackle basement odors:
- Place bowls of white vinegar around the basement to absorb musty smells.
- Mix equal parts of vinegar and water in a spray bottle and spray the solution on walls, floors, and surfaces where odors are strongest.
- Wipe down problematic areas like shelves, concrete walls, and wooden beams.
Vinegar neutralizes odors and kills mold spores, making it an ideal natural solution for musty basements.
3. Baking Soda and Activated Charcoal for Odor Absorption
Baking soda and activated charcoal are excellent at absorbing moisture and neutralizing odors. These natural substances work silently and effectively to cleanse the air.
- Place bowls of baking soda or activated charcoal in corners and near moisture-prone areas.
- Replace baking soda every 2 weeks and activated charcoal every month for continued effectiveness.
| Natural Absorber | Usage | Replacement Frequency |
|---|---|---|
| Baking Soda | Bowls or open containers in problem areas | Every 2 weeks |
| Activated Charcoal | Sachets or bowls | Monthly |
4. Houseplants for Natural Dehumidification
Some houseplants, like English Ivy, Peace Lily, and Boston Fern, can help reduce humidity and improve indoor air quality. Adding these to your basement can naturally help control moisture while giving the space a fresh look.
Note: Choose shade-tolerant plants as most basements have low light.
How to Get Rid of Musty Smell in Basement Fast
If you need to eliminate the musty odor quickly, especially before guests arrive or before using the basement for storage or recreation, follow these rapid-response tips.
1. Use a High-Efficiency Dehumidifier
Will a dehumidifier get rid of musty smell in basement? Yes! A powerful dehumidifier can significantly reduce moisture levels and prevent mold growth. Models that automatically adjust based on humidity are the best choice.
For large basements, choose a high-capacity dehumidifier that can handle substantial moisture removal. Refer to Bob Vila’s Best Dehumidifiers for top recommendations.
2. Clean All Surfaces with Mold-Killing Solutions
Scrub walls, floors, beams, and furniture with:
- White vinegar solution (1:1 ratio with water)
- Hydrogen peroxide spray for mold (3% solution)
- Commercial mold removers for stubborn spots
Focus on corners, hidden spots, and stored materials that may harbor mold and contribute to odor.
3. Remove Damaged or Moldy Materials
If you have carpets, rugs, drywall, or insulation that are water-damaged or moldy, remove and discard them. Soft materials hold moisture and are nearly impossible to fully clean once contaminated.
Replacing these materials prevents re-contamination and restores a healthier environment.
4. Use the Best Basement Odor Eliminator Products
Several commercial odor eliminators target tough basement smells. Options include:
- DampRid moisture absorbers
- Odor-neutralizing sprays
- Charcoal air purifying bags
These products help neutralize odors quickly, especially when paired with dehumidification and cleaning.

How to Get Rid of Musty Smell in Basement After Flood
Basements that have flooded are especially prone to lingering musty odors. Even after the visible water is gone, hidden moisture and mold can cause ongoing problems. Here’s how to address post-flood smells effectively.
1. Dry Out the Basement Completely
- Use water pumps, wet vacuums, and fans to remove standing water.
- Open windows and use dehumidifiers to speed up drying.
- Remove all wet carpets, drywall, and insulation as they can retain moisture and mold.
2. Sanitize and Disinfect
Once dry, sanitize all surfaces using a solution of 1 cup bleach to 1 gallon of water. This helps kill bacteria, mold, and mildew.
Refer to CDC’s official mold cleanup guide for more details.
3. Address Moisture Sources
Identify and fix the cause of flooding, whether it’s a foundation crack, plumbing leak, or poor drainage system. Waterproofing the basement is crucial to prevent future flooding and odors.
4. Apply Odor Neutralizers and Dehumidify
Finally, apply natural and commercial odor absorbers, and run a dehumidifier continuously for several days until humidity levels stabilize.
Long-Term Solutions to Prevent Musty Basement Smells
Once you’ve addressed the immediate issue, it’s important to prevent musty smells from coming back. Here are long-term strategies:
- Install a sump pump to handle excess water and prevent flooding.
- Seal foundation cracks and apply waterproof paint to walls and floors.
- Maintain gutters and downspouts to divert rainwater away from the home.
- Run a dehumidifier year-round in humid climates.
- Store items in plastic bins, not cardboard, to avoid moisture absorption.
- Ensure proper grading and drainage around the house to keep water away from the foundation.
- Fix plumbing leaks immediately to avoid water pooling in the basement.
