10 Essential Facts About Mold in Homes (And How to Protect Your Health)

Mold is a common and persistent issue that homeowners face, often hiding in places you least expect. Understanding how mold grows and how to prevent it is critical not only for your home’s structural integrity but also for the health and well-being of your family. Here are 10 important facts about mold in homes you should know—and what you can do about it.

1. Mold Can Cause Serious Health Issues

Exposure to mold can lead to a variety of health problems. Common symptoms include allergic reactions, respiratory issues, asthma attacks, and chronic sinus congestion. People with weakened immune systems, allergies, or lung diseases are especially vulnerable to the harmful effects of indoor mold.

2. You Can’t Completely Eliminate Mold Indoors

It’s important to understand that mold spores exist naturally both indoors and outdoors. Total mold elimination isn’t practical. However, the key to controlling mold growth inside your home is controlling indoor moisture levels.

3. Moisture Control Is Critical

If you discover mold in your home, it’s not enough to simply clean it off. You must address the source of the moisture—whether it’s a leak, poor ventilation, or high humidity—to prevent mold from returning.

4. Repair Water Leaks Immediately

Leaks are a primary source of mold problems. Whether it’s a roof leak, plumbing leak, or seepage around windows, it’s crucial to fix water issues quickly to stop mold growth before it starts.

5. Maintain Low Indoor Humidity Levels

Keep indoor humidity levels between 30% and 60% to minimize mold growth. Strategies for reducing humidity include:

• Venting bathrooms, dryers, and stoves to the outdoors

• Using dehumidifiers and air conditioners

• Increasing air circulation with fans

• Turning on exhaust fans during cooking, dishwashing, and cleaning

6. Act Fast After Water Damage

Building materials and furnishings that become wet need to be thoroughly dried within 24-48 hours. If not, mold can begin to grow and spread quickly throughout your home.

7. Clean Mold Properly

For hard surfaces, mold can often be removed with soap, water, and a brush. Be sure to dry the surface completely afterward. If porous materials like carpet, drywall, or ceiling tiles become moldy, they often cannot be cleaned effectively and should be replaced to prevent future contamination.

8. Prevent Condensation

Condensation provides a breeding ground for mold. Add insulation to cold surfaces like windows, pipes, walls, and roofs to reduce condensation and lower the risk of mold growth.

9. Avoid Carpeting in Moisture-Prone Areas

Carpet can trap moisture and become a perfect environment for mold. Avoid installing carpeting near drinking fountains, sinks, bathrooms, or in basements where humidity or leaks are common.

10. Mold Can Grow Almost Anywhere

Mold doesn’t discriminate—it can grow on wood, paper, carpet, food, and insulation. Anywhere there is moisture and organic material, mold can thrive. Regular home inspections, moisture control, and prompt repairs are your best defenses against a serious mold infestation.
