Mold and mildew are common issues in Central Florida due to high humidity levels (70%+), year-round warm temperatures, and heavy rainfall. Both can damage property and affect health, but they differ in appearance, growth patterns, and treatment methods:
- Mold: Fuzzy or slimy, dark colors (green, black, red), strong musty smell, penetrates surfaces deeply, causes structural damage, and severe health risks.
- Mildew: Flat, powdery, light colors (white, gray, yellow), mild musty odor, stays on the surface, easier to clean, and less harmful.
Quick Tips:
- Keep indoor humidity between 30-50% to prevent growth.
- Use the bleach test: If it lightens, it’s mildew; if not, it’s mold.
- DIY for mildew: Clean with vinegar or bleach solutions.
- Call professionals for mold: Especially for areas larger than 10 sq ft or HVAC contamination.

Mold vs. Mildew: What’s the Difference?
Mold vs. Mildew: Main Differences
Mold and mildew thrive in Florida’s humid climate but require different treatment methods. Here’s how they differ:
Appearance and Smell
| Characteristic | Mold | Mildew |
|---|---|---|
| Texture | Fuzzy or slimy | Flat and powdery |
| Color Range | Green, blue, black, or red | White, gray, or yellow |
| Odor | Strong, pungent musty smell | Mild musty odor |
| Growth Pattern | Penetrates surfaces deeply | Stays on the surface |
A 2021 University of Florida study examined 100 Central Florida homes and found mildew in 78% of bathrooms. Mold, on the other hand, was present in 45% of homes, particularly around AC units and in poorly ventilated attics.
To confirm what you’re dealing with, try the bleach test: Apply household bleach to the area. If it lightens within 1-2 minutes, it’s mildew. If it stays dark, you’re likely dealing with mold.
Where to Look for Growth
Common Mold Locations:
- Bathrooms and under sinks
- AC units and ductwork
- Poorly ventilated attics
- Water-damaged drywall
Typical Mildew Spots:
- Shower curtains and grout
- Window sills and tracks
- Fabrics in humid rooms
- Damp paper materials
The key difference lies in how they grow: Mold infiltrates materials and can cause structural damage, while mildew stays on the surface. To help prevent their spread, aim to keep indoor humidity below 60%.
Understanding these growth patterns can also help you evaluate potential health risks, which we’ll cover next.
Health and Building Damage
Mold and mildew pose different risks – mold requires immediate attention, while mildew calls for ongoing monitoring.
Mold Health Effects
Mold’s ability to deeply infiltrate materials makes it a serious concern. Research shows that up to 93% of chronic sinus infections are linked to mold exposure.
| Severity | Symptoms | At-Risk Groups |
|---|---|---|
| Mild | Sneezing, itchy eyes | Everyone |
| Moderate | Coughing, rashes | People with allergies |
| Severe | Asthma attacks, lung inflammation | Vulnerable individuals |
For those with asthma or COPD, mold can be especially dangerous, often triggering severe asthma episodes.
Mildew Health Effects
Mildew exposure is less severe but still causes discomfort, including:
- Temporary respiratory irritation
- Occasional headaches
- Mild allergic reactions
Prolonged exposure can worsen these effects, particularly for individuals with respiratory issues or compromised immune systems.
Knowing these health risks highlights the importance of correctly identifying mold and mildew, especially when evaluating potential structural damage.
Building Damage from Mold
The damage caused by mold progresses quickly, much like its health risks, making early action crucial.
Mold-related structural damage typically occurs in three stages:
- Surface Contamination: Spores spread through HVAC systems.
- Material Breakdown: Wood starts to rot, and drywall weakens.
- Structural Failure: Support beams decay, and ceilings may collapse.
"In buildings with significant mold growth, up to 50% of illnesses may be attributed to poor indoor air quality".
Regular inspections of areas prone to mold can help detect problems early, preventing both health and structural crises.
How to Remove Mold and Mildew
Mold and mildew require different approaches due to their nature. Mildew, which grows on surfaces, can often be handled at home. Mold, however, poses structural risks and usually calls for professional help.
Steps to Clean Mildew
You can safely clean mildew on your own with a few household items and proper safety gear. Here’s what you’ll need:
- N-95 respirator
- Nitrile gloves
- Safety goggles
- A well-ventilated workspace
For the cleaning solution, you can use either:
- A mix of equal parts white vinegar and water
- 1 cup of bleach combined with 1 gallon of water for non-porous surfaces
Spray the solution on the affected area, let it sit for 5 minutes, and scrub thoroughly. Always test the solution on a small, hidden area first to ensure it won’t damage the surface.
When to Call Mold Removal Experts
If you’re dealing with mold, especially in areas larger than 10 square feet, it’s time to bring in professionals. Here’s what professional mold remediation typically involves:
1. Assessment
Experts use tools like moisture meters and thermal imaging to locate and measure the extent of mold contamination.
2. Setting Up Containment
HEPA air scrubbers and negative air pressure systems are used to stop spores from spreading during the cleanup process.
3. Removal and Treatment
Professionals apply specialized antimicrobial treatments to eliminate deeply embedded spores that can cause respiratory issues. This process also helps to avoid costly structural damage, which can range from $15 to $30 per square foot.
These steps are most effective when paired with humidity control, which we’ll cover next.
