What Is Black Mold? And What Should San Diego Homeowners Do About It?

Everything you need to know about this dangerous mold type and how to deal with it

When people hear the words “black mold,” panic tends to follow. It’s often associated with serious health issues, frightening news stories, and costly repairs. While not every dark patch on a wall is toxic, black mold is real, and it can be dangerous if left untreated.

At Jakobsen Restoration, we’ve responded to black mold removal in San Diego homes, especially in damp areas like bathrooms, laundry rooms, attics, and crawl spaces. If you suspect you have black mold in your home, here’s what you need to know.

What Is Black Mold?

Black mold refers most commonly to Stachybotrys chartarum, a greenish-black mold that grows in moist environments with a constant water source. It thrives on materials like:

• Drywall
• Ceiling tiles
• Wood framing
• Carpet backing
• Insulation

Unlike other common molds, black mold is slow-growing but can release mycotoxins, toxic compounds that can affect the respiratory and immune systems in certain people.

Is Black Mold Dangerous?

While not everyone reacts the same way to mold exposure, black mold has been linked to:

• Persistent coughing or sneezing
• Eye and skin irritation
• Chronic fatigue or headaches
• Worsening of asthma or respiratory conditions
• In rare cases, neurological effects in sensitive individuals

The biggest risk comes from long-term exposure in poorly ventilated areas or when mold spores are released into the air during cleaning or disturbance.

If you live in an older home in San Diego neighborhoods like North Park, University Heights, or Mission Hills, moisture buildup combined with age-related structural leaks makes black mold a real possibility.

How to Identify Black Mold

Not all black-colored mold is toxic, and not all toxic mold is black. That’s why visual inspection alone isn’t enough. If you notice any of the following, it’s time to call in a pro:

• Dark patches or streaks on walls or ceilings
• Musty odor, especially in closed or humid spaces
• Water damage or recent leaks in the area
• Respiratory symptoms that improve when you leave home

At Jakobsen Restoration, we use moisture detection tools, air quality testing, and lab analysis when necessary to confirm the presence of black mold and determine the best removal method.

What to Do if You Find Black Mold

Do not try to clean black mold with bleach or household cleaners. Doing so can release spores and mycotoxins into the air and make the situation worse. Instead:

• Avoid disturbing the area
• Close off the room if possible
• Call a licensed mold remediation company like Jakobsen Restoration
• Document the damage for insurance purposes

We follow a certified process that includes containment, removal of contaminated materials, air scrubbing, and restoration. We also help San Diego homeowners prevent future mold growth by fixing the underlying moisture problem.

Why San Diego Homes Are at Risk

You might think San Diego’s dry, sunny weather makes mold less likely. But homes here still deal with:

• Poor ventilation, especially in older homes
• Roof leaks from aging shingles or flashing
• Humidity buildup from showers, laundry, and cooking
• Poorly sealed crawl spaces or basements

Even short-term moisture exposure can trigger mold growth in the right conditions.
