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.
What Our Customers Are Saying
EXCELLENT Based on 414 reviews Posted on Reg KingTrustindex verifies that the original source of the review is Google. We needed to have our crawl space "updated" in order to feel good about handing over the home to a new owner after 38 years! The service prior to the sale was thorough, informative and substantiated the costs of each part of the process. When the crew arrived on-site they were prompt, held a consistent clean work area, did a very neat "top drawer" job! Most of all they respected all of our property which is very important when bringing in outside agents! We appreciate the ownership and the young men who completed the work.Posted on David DouglasTrustindex verifies that the original source of the review is Google. Trey Moore, a Dry Otter tech came to our house on 6/3/26 for an annual review. He was punctual, courteous, and thorough.Posted on Joyce KluttzTrustindex verifies that the original source of the review is Google. We had an excellent experience with everyone who worked under our house. The initial inspection done by Mike revealed many things we didn't know, and the report was presented in a way I could understand. The drainage system was done first and fast, followed by a goodly amount of joist and sill repair, professionally done. The encapsulation was done by William and Josh, who did great work and made several trips to our house to make sure we were satisfied. It looks good under there. The new electric lights and switches will make future drain cleaning and pest inspections much easier than before.Posted on Donald NewmanTrustindex verifies that the original source of the review is Google. Outstanding performance. Arrived on time and worked all day. Completed encapsulation on time. Price was competitive. John, Corey, Desmond, Adam, Trey and Patrick were very professional and maintained communications with me. Always knew the status of the project. Great crew all around. Highly recommend Dry Otter for the Denver Area encapsulation. Crawlspace is great.Posted on ScottTrustindex verifies that the original source of the review is Google. Dry Otter has provided me with excellent, professional service since reaching out to them to upgrade my crawl space. Their competent service and technical expertise was always helpful. Also, their response to any questions or help was always met in a very timely manner. I want to call out specifically Adam, Trey, and Heather for all the assistance they provided. They went "above and beyond". I would recommend Dry Otter (and have numerous times) to anyone needing help with waterproofing services.

Contacted dry otter for installing a dehumidifier and encapsulation, they promptly scheduled an estimate and were willing to work with me about what I could accommodate in terms of budget.
