How to Remove Black Mold
Tips for Safely Removing Black Mold
Understanding Black Mold
Black mold is a common household problem, but it is often misunderstood. There are many types of mold that can appear black, but not all are toxic. However, regardless of type or color, mold can cause health issues, particularly for those with asthma or breathing problems. If you’re dealing with a large mold infestation or are uncertain about the type, it’s best to contact a professional for removal to avoid further health risks.
If the amount is small and hasn’t penetrated deep into surfaces, it’s generally safe to clean and remove black mold yourself with the proper precautions.
How to Remove Black Mold Safely
When to Call a Professional
Some types of black mold can release toxic gases when present in large quantities. Mold often grows on materials like drywall, cardboard, wood, insulation, or ceiling tiles—particularly when they’ve been repeatedly exposed to moisture. If the mold has spread to walls, floors, or ceilings, it’s crucial to address the source of moisture (such as leaks) before attempting removal. For mold that has penetrated deeply, hiring a professional is the safest course of action.
Cleaning Small Mold Stains Yourself
If the mold is manageable and hasn’t penetrated deep into surfaces, follow these steps to safely remove it:
- Wear Personal Protective Equipment (PPE)
Mold spores can cause respiratory problems, so it’s essential to wear a mask, preferably an N95 rated masks, to prevent inhalation. Cover your skin with gloves and protective clothing as well. - Dry the Affected Area
Clean items only when they are dry. Take affected belongings outside, where the air circulation will prevent mold spores from spreading inside your home. - Discard Heavily Contaminated Items
Carpets, rugs, or other porous materials with heavy mold contamination should be discarded, as it’s nearly impossible to fully remove mold from them. Seal these items in heavy-duty plastic bags before disposal. - Cleaning Mold in Bathrooms
For bathroom mold, a mixture of bleach and water works well. Here’s how to clean it:- Mix 1 cup of bleach with 1 quart of water in a spray bottle.
- Spray the moldy area and scrub with a brush.
- Rinse thoroughly to remove all bleach residue.
Preventing Mold Growth
Prevention is key when dealing with mold. Once you’ve cleaned up an area, take steps to prevent mold from returning.
Keep Moisture Levels Low
Mold thrives in damp environments. Use a dehumidifier in areas prone to moisture, and fix any leaks or water damage immediately. Wipe down sinks, tubs, and shower stalls after use to reduce moisture and soap scum—two things mold feeds on. Use a squeegee on glass doors and walls after showering.
Waterproof Your Basement
Basements are particularly vulnerable to mold growth, especially older ones. If your basement is prone to flooding or dampness, consider having it professionally waterproofed to prevent moisture from seeping in.
Regularly Inspect Problem Areas
Check areas that are prone to humidity or have been wet for mold growth. Mold can develop quickly and damage porous materials like wood and fabric.
Know When to Call a Pro to Remove Black Mold
If you discover mold on materials containing cellulose (such as drywall or insulation) or if the infestation is extensive, it’s safest to consult a professional. They have the tools and expertise to safely remove the mold without spreading spores throughout your home.
Taking prompt action and following these tips can protect your home and health from the dangers of black mold.
