Discovering mold in your home can be unsettling. Not only can mold damage belongings, but certain types can also pose health risks. You need to take swift action to remove it, but deciding whether to tackle mold removal as a DIY project or hire professionals depends on several factors. This guide will help you understand when it’s safe to handle mold yourself and when it’s time to call in the experts.
Determine the Extent of Mold Growth
Before deciding on a course of action, assess the size of the affected area. The U. S. Environmental Protection Agency (EPA) recommends contacting licensed professionals if the mold-affected area exceeds 10 square feet. Be aware that visible mold may not always reveal the full extent of the problem, especially if there’s hidden growth within walls.
Some common indicators that may suggest hidden mold growth, including persistent allergic reactions, dark stains on the ceilings or walls, musty odors, peeling paint or wallpaper, and ongoing moisture problems.
If your home shows any of these signs, consult a professional for a thorough inspection. Hidden mold may require specialized detection methods.
In cases of significant damage or complications caused by mold, home insurers may require documentation from a professional—especially if the mold has spread extensively through walls or other structural components.
Mold Spores and Their Spread
Mold reproduces through tiny, invisible spores that can easily become airborne and spread throughout a home. HVAC systems can distribute these spores throughout your home.
Exposure to airborne mold spores can be particularly dangerous for individuals with asthma, allergies, or compromised immune systems.
You can use air sampling kits to test for mold spores—you send samples to laboratories for analysis. Professional inspections can also detect airborne mold problems you can’t see.
Dealing with Surface Mold
The type of surface on which mold is growing affects how difficult it is to remove. Mold on nonporous surfaces is often easier to clean and you can sometimes handle it as a DIY project.
DIY Mold Removal on Nonporous Surfaces
For small areas of surface mold on nonporous materials, you can clean it yourself using a commercial cleaner, but you must tackle the underlying moisture issue to prevent regrowth.
When To Call Professionals for Surface Mold
Mold growing on porous materials such as carpeting or drywall can be much more challenging to remove completely. Professional treatment or replacement may be needed.
Controlling Humidity To Prevent Mold Growth
High indoor humidity levels support mold growth. Keep indoor humidity between 30% and 50% to discourage mold formation.
Installing a dehumidifier can help remove excess moisture from the air, making it less hospitable for mold. While it doesn’t address the root cause of humidity issues, it can be an effective temporary measure.
Investigate potential sources of excess moisture, such as leaky pipes, poor ventilation, or malfunctioning HVAC systems.
The Importance of Prompt Action
When it comes to mold growth, time is of the essence. Mold can begin to form in as little as 48 hours after exposure to excess moisture.
In the event of flooding or significant water damage, take immediate action to dry the affected area. Removing water-logged items and setting up fans and dehumidifiers is an effective solution in most mild to moderate cases of moisture problems. For serious cases, call a water damage remediation specialist to ensure that the source of the problem is fixed and all moisture and water damage is remedied.
Understanding Black Mold
The term “black mold” often strikes fear in homeowners, but it’s important to understand that not all black-colored mold is toxic.
Toxic Vs. Nontoxic Black Mold
The toxic variety of black mold, known as Stachybotrys chartarum, releases spores when physically disturbed, especially when wet. Nontoxic black mold can appear in areas without sustained water damage and is generally easier to clean. Knowing the difference will help you decide whether you need professional intervention if you can remove the mold with basic cleaning practices.
When To Be Concerned About Black Mold
If you find black mold in areas with ongoing moisture issues or it has a strong, musty odor, it’s best to consult a professional. These could be signs of the more dangerous toxic variety. Professional evaluation can help determine the most appropriate remediation techniques.
When To Call the Pros
You should contact professional mold remediation services if:
- The area affected by mold is larger than 10 square feet
- You suspect hidden mold growth
- Mold returns after DIY removal attempts
- You have health concerns related to mold exposure
FAQs About Mold Removal
For what size of mold-contaminated area should I call professional cleaners?
For suspected hidden mold over 10 square feet, contact professionals. Mold behind walls is tough to gauge.
How do I check for airborne spores?
Consider hiring air sampling technicians or buying home test kits to collect samples for analysis in a lab.
Is black mold hazardous?
Prolonged moisture enables black mold to release toxins. Patches of surface mold without a continuous moisture source can be treated as a DIY project.
How quickly should I fix leaks?
Act urgently to dry flooded areas or areas exposed to leaks to eliminate mold risks. Mold forms in as little as 48 hours.
Can I handle surface mold myself?
For nonporous surfaces, mold often wipes away with commercial solutions. However, porous materials such as carpeting will likely require treatment or replacement by pros.
