Crawl Space Fungus Treatment: Effective Solutions


Crawl spaces are often overlooked areas of the home, but they play a critical role in the overall health and integrity of the building. Unfortunately, these dark and damp environments create the perfect conditions for mold and fungus growth, which can lead to significant problems for homeowners.
If left untreated, crawl space fungus can not only damage the structural elements of your home but also pose serious health risks. This article will explore crawl space fungus treatment options so you can have a safe and healthy home again.
1. Remove Existing Mold and Fungus
The first step in treating crawl space fungus is to remove any existing mold or fungal growth. This process involves identifying affected areas and thoroughly cleaning them to remove the mold.
Homeowners may choose to tackle small areas of mold growth themselves. However, larger infestations or those that involve structural damage typically require professional intervention.
Don’t put your loved ones in danger by doing a DIY job for such extreme infestations. It’s not worth the long-term consequences.
DIY Removal
For minor cases, homeowners can use a mixture of water and mild detergent or specialized mold cleaners to scrub away mold from surfaces. It’s important to wear protective gear, including gloves and a respirator, to avoid inhaling mold spores.
Professional Mold Solutions
For larger infestations or if the mold has penetrated structural elements like wooden beams, hiring a professional mold solutions service is recommended. Professionals use stronger cleaning agents, HEPA vacuums, and industrial-grade fungicides to remove mold and ensure it doesn’t return.
2. Fix Moisture Problems
One of the most crucial aspects of crawl space fungus treatment is eliminating the source of moisture that caused the fungus to grow in the first place. Without addressing the moisture problem, any mold removal efforts will be temporary.
Here are some common causes of the excess moisture that contributes to a humid environment that causes crawl space fungus:
- Leaks from plumbing systems, broken pipes, or groundwater seepage
- If water pools around the foundation or enters the crawl space
- Unsealed dirt floors allow moisture to rise from the ground
Here are some key steps for controlling moisture.
Repair Leaks
Identify and fix any plumbing leaks or water intrusion issues that may be contributing to excess moisture in the crawl space. This could involve repairing damaged pipes, fixing foundation cracks, or replacing faulty gutters.
Improve Drainage
Make sure that water is properly draining away from the home’s foundation. Installing a French drain or adjusting the landscaping around the house to slope away from the foundation can help prevent water from entering the crawl space.
Seal Crawl Space Floors
If the crawl space has a dirt floor, consider installing a vapor barrier. Vapor barriers are thick plastic sheets that cover the floor and walls of the crawl space, preventing moisture from rising from the ground.
3. Dehumidification
Installing a dehumidifier in the crawl space can help control humidity levels and prevent future mold growth. Dehumidifiers are particularly effective in regions with naturally high humidity or during the rainy season.
A crawl space dehumidifier can reduce moisture in the air, making it less conducive to mold and fungus growth.
Crawl Space Dehumidifiers
These are specially designed to operate in the damp, low-ceiling environments of crawl spaces. They are often equipped with automatic humidity sensors to maintain optimal moisture levels. According to the EPA, this level should ideally be around 30-50% but never exceed 60%.
Ventilation
Ensuring proper airflow in the crawl space is another way to reduce humidity. Some homes may benefit from installing additional vents or fans to improve ventilation, though the right approach depends on the specific climate and crawl space conditions.
4. Encapsulation
Encapsulation is a highly effective long-term solution for preventing moisture buildup and fungal growth in crawl spaces. This process involves completely sealing the crawl space with a combination of vapor barriers and insulation, effectively turning it into a dry, controlled environment.
Full Encapsulation
During encapsulation, professionals install a heavy-duty plastic barrier on the walls, floors, and sometimes the ceiling of the crawl space. This seals out moisture from the soil and surrounding environment.
Insulation
In addition to vapor barriers, insulation is often installed to help regulate the temperature in the crawl space. This prevents condensation and moisture buildup.
Sealed Vents
In some cases, encapsulation involves sealing off crawl space vents to prevent outside air from entering. However, in other cases, mechanical ventilation systems may be installed to maintain airflow without introducing excess moisture.
5. Fungicidal Treatment
In cases of severe or recurring fungal growth, applying fungicidal treatments may be necessary to prevent mold from coming back. Fungicides are chemical agents specifically designed to kill mold and mildew, and they can be applied after the mold removal process as a preventative measure.
Fungus removal methods involve fogging the crawl space with a fine mist that disperses the fungicide evenly throughout the space, penetrating hard-to-reach areas and killing lingering mold spores.
Fungicidal sprays can also be applied directly to affected areas to kill mold and prevent regrowth.
6. Regular Inspections and Maintenance
Once the crawl space has been treated for fungus, ongoing maintenance and inspections are key to ensuring the problem doesn’t return. Regularly check for signs of moisture, mold, or structural damage, especially after heavy rains or during the more humid seasons. Schedule this into your calendar so you never miss this important checkup.
Schedule professional inspections annually to assess the condition of your crawl space and address any issues before they escalate.
