Pets & Mold: How Indoor Mold Affects Cats, Dogs, and Other Animals
Pets are naturally curious and love to explore every corner of your home. However, that curiosity can expose them to harmful mold spores, especially in damp areas like basements or crawl spaces. Mold thrives in dark, humid environments, and once it spreads, it can cause serious health problems for your pets.
This page explores mold and its impact on your pets.
Signs of Mold Exposure in Pets
Pets can’t tell you when they’ve been exposed to indoor mold, but their symptoms can signal trouble. When inhaled, floating mold spores may trigger respiratory and allergic reactions. Watch for the following warning signs:
- Itchy, watery eyes
- Nasal discharge
- Excessive scratching or licking (without fleas present)
- Secondary skin infections
- Wheezing, coughing, or labored breathing
- Bleeding from the nose or mouth
When pets are exposed to mold, they may experience a range of health effects, from mild to severe. According to the U.S. Food and Drug Administration, prolonged exposure may cause some animals to develop neurological or behavioral changes.
Veterinary Care and Recovery
If you suspect mold exposure, contact your veterinarian immediately. Given the many strains and species of mold, ensure your local vet is aware of potential mold exposure. Treatment may include detoxifying medications, antibiotics, and supportive care such as IV fluids or hospitalization in severe cases. With prompt attention, most pets recover fully. However, it’s critical to eliminate the mold source before bringing your pet home to prevent re-exposure.
Where Mold Grows Indoors
Mold thrives in damp, dark, and poorly ventilated areas, including basements, crawl spaces, attics, bathrooms, and around windows where pets rest. While not all molds are toxic, black mold, Stachybotrys chartarum, poses serious risks.
This mold type produces mycotoxins that can enter the bloodstream, damaging the liver and reducing the body’s ability to clot blood. Severe exposure has been linked to nosebleeds and respiratory distress in both pets and humans.
Preventing Mold Growth in Basements and Crawl Spaces
Even if your pets never enter your basement or crawl space, airflow carries mold spores upward into living areas. Nearly half of the air you breathe indoors originates from these below-grade spaces. If moisture or mold is present, it can affect everyone in your home, including your pets. To prevent mold growth:
- Use a basement dehumidifier to reduce humidity.
- Install an interior drainage and sump pump system
- Apply a vapor barrier and insulation
- Seal cracks in basement walls and floors.

Basement Waterproofing FAQs
You know your basement needs waterproofing if you notice signs of moisture, such as musty odors, mold, stains, puddles, efflorescence, or wall cracks.
We’ve saved the best concern for last. Undoubtedly, this is one of the most-asked homeowner questions. It’s a big deal, and we understand that. We also understand how frustrating it can be to not get a straight answer right away from our office.
To give you a general idea, homeowners can expect to spend an average of $4,000 on basement waterproofing. Various projects that go into the repairs typically range from $2,000 to $10,000. The return on investment from basement waterproofing is estimated to be around 30 percent.
There’s a lot to consider with the cost of wet basement repairs. Because every house is unique and has its own different repair needs, there’s no “one size fits all” solution. What may have worked for even your next-door neighbor’s home might not be exactly what your house needs.
That’s another reason why being present for an appointment with one of our certified inspectors is so important. The inspector needs to physically be in your home to look at the problems and get a better idea of what’s going on. He will then be able to customize repair solutions specific to your home’s repair needs. Along with your budget and repair goals, your inspector also will take the severity of damage or problem areas, square footage, and amount of material needed into consideration.
Even though the cost can range significantly depending on the basement problems and needs, can you really put a price on your peace of mind and family’s health? Think of it as an investment with priceless benefits.
