What is Mold?
Mold is a general term for fungi that can grow in various colors, including black, green, white, and red. Mildew is often powdery and white, while mold can be fuzzy or slimy.
Your crawl space is the perfect target for mold growth, especially if you live in a warm, wet climate. This matters because the air in your crawl space is shared with the air in your home. Studies show that 40-50% of the 1st floor air in your home originates from the crawl space.
Mold can severely threaten your health and home’s integrity, so regularly monitoring your crawl space is vital.
If you find mold in your crawl space, it is time to call a professional for crawl space mold removal.
How Do I Know if My Crawl Space Has Mold?
Musty House Smell
If you notice a musty or earthy smell in your home, this is a tell-tale sign you have a mold issue. Often, this is the first sign of trouble and a good indication that it is time to call a professional.
Mold is visible
Look for white mold on walls, mold on floor joists, and black, brown, and green patches. Mold is usually found on joists, insulation, walls, and floors.
Mold can also grow on your crawl space’s ductwork, pipes, and other materials.
Water stains
Look for water stains in your crawl space. If you see water stains on the joists, walls, or floors of your crawl space, this clearly indicates that you need to call Dry Otter Waterproofing for crawl space mold removal.
Warped wood
If you see rotting or warped wood in your crawl space, the culprit is most likely mold.
Increase in respiratory issues
Mold can cause serious health issues affecting the respiratory tract, like allergies, asthma, and other severe respiratory infections. Mold spores can increase the severity of allergies and asthma in people who already suffer from these conditions.
If you see any signs of mold, cleaning a crawl space is the best plan to avoid the dangers associated with mold growth.
Causes of Crawl Space Mold
- Water damage: Any significant source of water can induce mold growth. Leaks, flooding, and even simple condensation are enough to cause mold growth.
- High humidity: Crawl spaces are close to the ground, so they naturally have a more humid environment. The dampness and lack of ventilation provide the perfect place for mold growth.
- Poor ventilation: Lack of airflow allows moisture to accumulate and sit in the space, creating the perfect conditions for mold growth from stagnant air.
- Organic materials: Things like wood and paper provide the materials that feed mold and encourage growth.
- Warm environment: Mold likes temperatures between 60 and 90 degrees Fahrenheit, and crawl spaces typically fall in that range. You can expect high temperatures in your crawl space if you live in a naturally warm climate.
- Lack of sunlight: Crawl spaces are usually dark with little to no sunlight. Sunlight is a natural mold killer.
- Cracks: Cracking in the walls or foundation of your crawl space allows moisture to enter the crawl space, promoting mold growth.
- Plumbing leaks: Often, plumbing runs under the house in the crawl space, and leaking pipes and drains provide the moisture needed for mold growth.
- Condensation and soil moisture: When warm air cools, moisture is released, and soil surrounding the crawl space can also influence humidity levels.
- Additional issues: Porous crawl space walls, lack of vapor barrier, and improper grading can cause mold problems. Insufficient ground cover, like gravel or mulch that diverts rainwater from your home’s foundation, can also lead to mold growth.
Mold Remediation
Dry Otter Waterproofing has several solutions for crawl space mold removal and remediation. The first step is installing a negative air fan in the crawl space. Next, we put an air scrubber inside your home, and the HVAC system is turned off.
After completing this step, Dry Otter technicians remove all raised fungus with an antimicrobial solution. This completes the mold removal process.
What are the benefits of crawl space mold remediation?
The most significant benefit to removing mold from your crawl space is your health. Mold can cause many respiratory issues, and mold elimination allows everyone to breathe more easily.
This is especially important if you already suffer from allergies, asthma, or other severe respiratory issues.
Along with better indoor air quality, mold removal will address the problem of mold eating into floor joists, which can compromise your home’s structural integrity. Having a proper system and professional cleaning that eliminates mold will increase the value of your home.
Dry Otter Waterproofing is here to help you breathe easier. We have the tools and expertise to handle any mold issues in your crawl space.

EXCELLENT Based on 367 reviews Posted on Dylan CallicuttTrustindex verifies that the original source of the review is Google. I recently had Dry Otter Waterproofing complete a full crawlspace transformation at my home, and I couldn’t be more impressed with the results. Michael, Will, Josh, and Adam were outstanding from start to finish. Their professionalism, attention to detail, and clear communication made the entire process smooth and stress-free. They installed a sump pump, dehumidifier, full encapsulation, and several other improvements to protect my home from moisture issues. The crew worked efficiently, kept me informed at every step, and treated my property with great respect. The difference in my crawlspace is incredible — clean, dry, and well-protected.
