Mold in the home is a common problem, especially in damp or poorly ventilated areas. While some mold issues can be handled safely on your own, others require professional remediation. Knowing the difference is critical for your health and for preventing the mold from returning.
Below is a practical guide on what you can do yourself—and what you should never do when dealing with mold. For more information please visit strictlywaterdamagerestoration.com
What You Can Do Safely
1. Handle Small Areas Only
DIY mold removal is appropriate only for small patches (generally less than 1 square meter / 10 square feet). These are often found on:
- Bathroom tiles and grout
- Window sills
- Kitchen walls near sinks
- Non-porous surfaces
If mold covers a large area or keeps coming back, stop and call a professional.
2. Wear Proper Protection
Even small mold jobs require basic safety gear:
- Gloves (rubber or nitrile)
- A mask (preferably N95 or higher)
- Eye protection
- Old clothing or disposable coveralls
This helps prevent inhalation and skin contact with mold spores.
3. Use the Right Cleaning Solutions
For non-porous surfaces, effective DIY options include:
- White vinegar (undiluted)
- Hydrogen peroxide (3%)
- Baking soda mixed with water
- Mild detergent and warm water
Apply, scrub gently, and let the area dry completely.
4. Fix the Moisture Problem
Mold always needs moisture to grow. After cleaning:
- Repair leaks
- Improve ventilation
- Use a dehumidifier if needed
- Keep humidity below 50%
Without fixing the moisture source, mold will return.
What You Should Avoid at All Costs
1. Don’t Use Bleach on Porous Materials
Bleach may remove surface stains, but it does not kill mold roots in materials like:
- Drywall
- Wood
- Carpet
- Ceiling tiles
It can actually make mold grow back stronger.
2. Don’t Mix Cleaning Chemicals
Never mix bleach with vinegar, ammonia, or other cleaners. This creates toxic gases that can cause serious health problems.
3. Don’t Paint Over Mold
Painting or sealing mold without removing it first only hides the problem. Mold will continue to grow underneath and spread further.
4. Don’t Disturb Large Mold Areas
Scraping or scrubbing large mold infestations releases spores into the air, spreading contamination throughout your home.
If the mold:
- Covers a large area
- Is inside walls or ceilings
- Is caused by flooding or sewage
- Causes health symptoms
👉 Professional mold remediation is the only safe option.
When to Call a Professional
You should stop DIY efforts and seek expert help if:
- Mold keeps coming back
- You smell strong musty odors
- You or family members experience allergies or breathing issues
- The mold is black, widespread, or hidden
Final Thoughts
DIY mold removal can be effective only for small, surface-level problems when done correctly and safely. Knowing your limits is essential. When in doubt, choosing professional mold removal protects both your home and your health.
