How Do You Get Rid Of Mold Smell?

The key to eradicating mold smell is addressing the underlying mold growth itself, rather than simply masking the odor. Once the source is eliminated, thorough cleaning, ventilation, and sometimes professional intervention are necessary to completely remove the lingering scent.

Understanding the Mold Smell: The First Step to Elimination

The musty, earthy odor associated with mold isn’t just unpleasant; it’s a telltale sign of a potentially hazardous problem lurking within your home. This smell comes from microbial volatile organic compounds (MVOCs), gases produced by actively growing mold colonies. Understanding the source and nature of these MVOCs is crucial to effectively eliminating the odor. Ignoring the smell is never a solution; it almost certainly indicates a growing issue.

Locating the Source of the Odor

Before you can treat the smell, you need to find the mold. This often involves detective work. Obvious signs of mold, like visible patches on walls or ceilings, make identification easy. However, mold often thrives in hidden areas, such as behind drywall, under carpets, inside walls, or in poorly ventilated spaces like basements and crawl spaces.

Visual Inspection: Use a flashlight to meticulously examine areas prone to moisture, like bathrooms, kitchens, laundry rooms, and basements. Look for discoloration, staining, or fuzzy growth.
Sniff Test: Follow your nose. The strongest smell usually indicates the source is nearby.
Moisture Detection: Use a moisture meter to check for elevated moisture levels in walls, floors, and ceilings. High moisture readings suggest mold is likely present, even if it’s not visible.
Professional Inspection: If you suspect mold but can’t find it, or if the affected area is large, a professional mold inspector can use specialized equipment and techniques to locate hidden mold colonies.

Eliminating the Mold: The Foundation of Odor Removal

Once you’ve located the mold, the next step is to eliminate it. The removal process depends on the size and location of the infestation.

DIY Mold Removal: When to Handle It Yourself

For small mold patches (less than 10 square feet), you can often handle the removal yourself. Follow these steps:

Contain the Area: Seal off the affected area to prevent the spread of mold spores to other parts of your home. Use plastic sheeting and tape to create a barrier.
Protective Gear: Wear gloves, a mask (N-95 or higher), and eye protection to protect yourself from mold spores.
Cleaning Solution: Mix a solution of bleach (one part) and water (ten parts), or use a commercially available mold cleaner.
Scrub and Clean: Thoroughly scrub the affected area with the cleaning solution, removing all visible mold.
Rinse and Dry: Rinse the cleaned area with clean water and dry it thoroughly with towels. Use a dehumidifier or fan to speed up the drying process.
Dispose of Materials: Dispose of any sponges, rags, or other materials used for cleaning in a sealed plastic bag.

Professional Mold Remediation: When to Call in the Experts

For large mold infestations (over 10 square feet), or if you are sensitive to mold or have respiratory problems, it’s best to hire a professional mold remediation company. Professionals have the expertise, equipment, and training to safely and effectively remove mold. They will:

Assess the Damage: Conduct a thorough inspection to determine the extent of the mold growth.
Contain the Area: Implement strict containment measures to prevent the spread of mold spores.
Remove Mold-Infested Materials: Remove and dispose of mold-infested materials, such as drywall, carpeting, and insulation.
Clean and Disinfect: Clean and disinfect all affected surfaces with antimicrobial solutions.
Dry the Area: Use commercial-grade dehumidifiers and fans to thoroughly dry the affected area.
Test for Mold: Conduct post-remediation testing to ensure the mold has been completely removed.

Removing the Mold Smell: Bringing Back Fresh Air

Even after the mold is gone, the musty smell may linger. Here’s how to eliminate it:

Ventilation

Open windows and doors to air out the affected area. This helps remove lingering MVOCs.
Use fans to circulate air and speed up the drying process.
Run a dehumidifier to reduce moisture levels and prevent future mold growth.

Cleaning

Clean all surfaces in the affected area with a mild detergent and water.
Wash or dry clean any fabrics or textiles that were exposed to mold.
Deep clean carpets and upholstery using a professional steam cleaner with a mold-killing solution.

Odor Absorbers

Baking Soda: Place open boxes of baking soda in the affected area to absorb odors.
Activated Charcoal: Activated charcoal is a powerful odor absorber. Place bowls of activated charcoal or use charcoal air filters.
White Vinegar: Place bowls of white vinegar in the affected area to neutralize odors.
Ozone Generators: Use with extreme caution. Ozone generators can be effective at removing odors, but they can also be harmful to your health. Follow the manufacturer’s instructions carefully and ensure the area is unoccupied during use.

Sealing

Seal porous surfaces like concrete floors or walls with a mold-resistant sealant to prevent future mold growth and trap any remaining odors.

FAQs: Deeper Dive into Mold Smell

Here are some frequently asked questions about mold smell, providing additional insights and practical solutions:

1. Can mold smell make you sick?

Yes, exposure to mold and its MVOCs can cause a variety of health problems, including allergic reactions, respiratory problems, and skin irritation. Some molds also produce mycotoxins, which can be even more harmful. Symptoms can range from mild to severe, depending on the individual’s sensitivity and the type and amount of mold present.

2. What is the difference between mildew and mold smell?

While both mildew and mold produce musty smells, mildew is typically less intense and easier to remove. Mildew grows on the surface of materials, while mold penetrates deeper. If the smell is very strong and pervasive, it’s more likely to be mold.

3. Can you get rid of mold smell with air fresheners?

Air fresheners only mask the smell temporarily; they do not eliminate the underlying mold problem. Covering up the smell without addressing the source can actually worsen the problem by allowing mold to grow undetected.

4. What is the best way to identify hidden mold?

The best way to identify hidden mold is to look for signs of moisture damage, such as water stains, discoloration, or peeling paint. Use a moisture meter to check for elevated moisture levels in walls and floors. If you suspect mold but can’t find it, hire a professional mold inspector.

5. How long does it take for mold smell to go away after mold removal?

The amount of time it takes for the mold smell to disappear depends on the extent of the mold growth, the thoroughness of the removal process, and the effectiveness of the cleaning and ventilation efforts. It can take anywhere from a few days to several weeks.

6. Does homeowners insurance cover mold removal?

Homeowners insurance typically covers mold removal if the mold is caused by a covered peril, such as a burst pipe or roof leak. However, mold caused by neglect or lack of maintenance is usually not covered.

7. What are the most common causes of mold growth in homes?

The most common causes of mold growth in homes include leaks, flooding, poor ventilation, high humidity, and condensation.

8. How can I prevent mold growth in my home?

You can prevent mold growth by controlling moisture levels, repairing leaks promptly, ensuring proper ventilation, cleaning regularly, and using mold-resistant building materials.

9. Are there specific types of mold that have a stronger smell?

Yes, some types of mold, such as Stachybotrys chartarum (black mold), are known for having a particularly strong and unpleasant odor. However, the intensity of the smell can also depend on the size of the mold colony and the environmental conditions.

10. Can vinegar kill mold and eliminate the smell?

White vinegar can kill some types of mold on surfaces and help reduce the smell. However, it is not as effective as bleach or commercial mold cleaners for killing all types of mold, particularly on porous surfaces.

11. Is it safe to live in a house with mold smell?

It’s generally not safe to live in a house with a mold smell, as it indicates the presence of mold that can negatively impact your health. Address the mold issue promptly to protect your well-being.

12. What should I do if the mold smell persists even after cleaning?

If the mold smell persists after cleaning, it indicates that mold may still be present in hidden areas or that the initial cleaning was not thorough enough. Re-inspect the area, consider hiring a professional mold inspector, and repeat the cleaning process, paying close attention to ventilation and drying. You might also need to remove and replace materials that are heavily infested with mold.
