Frequently Asked Questions

The number of asbestos samples required by the Air Quality Management District (AQMD) can vary depending on several factors, including the size of the area being tested, the type of material, and the specific regulations of your local AQMD. However, the general guidelines for asbestos sampling typically suggest:

1. Homogeneous Areas: You should collect samples from each homogeneous area of material that is suspected to contain asbestos. A homogeneous area is defined as an area of material that is uniform in color, texture, and date of application.
2. Number of Samples:
   • For areas under 1,000 square feet, typically 3 samples are needed.
   • For areas between 1,000 and 5,000 square feet, typically 5 samples are needed.
   • For areas over 5,000 square feet, typically 7 samples are needed.
3. Types of Materials:
   • Friable materials (easily crumbled by hand) usually require more sampling than non-friable materials.
   • Different materials (flooring, insulation, walls, etc.) will require separate sampling.

Mold is a type of fungus that grows in the form of multicellular filaments called hyphae. It thrives in damp, warm, and humid environments and reproduces by releasing tiny spores into the air. Mold can grow on a variety of surfaces, including walls, ceilings, floors, and even furniture, as long as there is moisture present.

Black mold, also known as Stachybotrys chartarum or Stachybotrys atra, is a specific type of mold that is often black or dark green in color. It can grow on materials with a high cellulose content, such as wood, paper, and drywall, when there is excessive moisture from leaks, flooding, or high humidity.

Is Black Mold a Concern?

Yes, black mold can be a health concern, especially in large quantities or if people are exposed to it over long periods. It produces mycotoxins, which can potentially cause health problems, particularly for people who are sensitive or have respiratory issues.

Potential Health Effects:

1. Allergic Reactions: Sneezing, coughing, runny nose, skin rashes, and watery eyes are common symptoms for those sensitive to mold.
2. Respiratory Issues: Prolonged exposure to black mold can cause or exacerbate asthma, bronchitis, or other respiratory issues.
3. More Severe Symptoms: In rare cases, exposure to black mold can lead to chronic fatigue, persistent headaches, or even more serious health complications for those with weakened immune systems.

Mold self-testing kits from the store can offer some basic insights, but they have limitations in terms of reliability and accuracy. Here’s a breakdown of the pros and cons of mold self-testing kits versus professional air sampling:

Mold Self-Testing Kits:

Pros:

1. Convenient and Inexpensive: These kits are relatively cheap and can be purchased from most hardware or home improvement stores.
2. Easy to Use: They are straightforward, usually involving swabbing or collecting samples from visible mold growth.
3. Initial Identification: Some kits can tell you if mold is present and may identify common types of mold.

Cons:

1. Limited Accuracy: Store-bought kits may not detect all types of mold, and they can give false positives or negatives. Environmental factors like air circulation or placement of the kit can affect results.
2. No Mycotoxin Detection: Self-testing kits don’t test for mycotoxins (the toxins produced by certain molds, like black mold), which are often more harmful than the mold spores themselves.
3. No Quantification: These kits might not tell you how much mold is present or if the levels are hazardous.
4. Can't Test Air Quality: Most kits only test surface samples, so they won’t give an indication of airborne mold spores, which can still pose a risk even if mold isn’t visibly growing.

Professional Air Sampling:

Pros:

1. Comprehensive Analysis: Professional air sampling can detect airborne mold spores and provide more detailed information, including the type of mold and concentration levels.
2. Assessment of Hidden Mold: Air sampling can help identify mold problems in areas where it might not be visible, such as inside walls, ceilings, or HVAC systems.
3. Health Risk Evaluation: Professionals can interpret the results in terms of health risk and advise on whether remediation is necessary.
4. Mycotoxin Detection: A professional mold assessment can test for mycotoxins and assess potential health risks.

Do You Need Air Sampling?

If you are concerned about the possibility of hidden mold or suspect you have a significant mold problem (especially with symptoms like a musty smell, water damage, or health concerns like allergies or respiratory issues), air sampling by a professional is highly recommended. Air sampling is also beneficial if you suspect mold but can't see it, as airborne spores can still impact air quality and health even if no visible mold is present.

In conclusion, mold self-testing kits can be useful for an initial check, but they aren't as reliable or thorough as professional testing. For significant concerns, professional air sampling provides a more accurate and comprehensive assessment of the mold problem and potential health risks.

Condol’s Environmental Services does not perform mold, asbestos, or lead hazard remediation, repair, or construction services. Doing so would present a conflict of interest and would not benefit our clients. Additionally, as we are certified by the State of California Department of Public Health and the Department of Occupational Health and Safety, our certifications prohibit inspectors from performing remediation and certified contractors from conducting inspections.

Yes, you should still be concerned about lead-based paint and lead   hazards, especially if your home was built before 1978. Here’s why:

Why Lead-Based Paint is a Concern:

1. Homes Built Before 1978: Lead-based paint was widely used in homes prior to 1978, when it was banned in residential properties in the U.S. If your home was built before then, there’s a good chance that it contains lead-based paint, especially in older layers beneath newer coats of paint.
2. Health Risks: Lead exposure, especially in young children, can cause serious health problems, including developmental delays, learning difficulties, irritability, and in severe cases, damage to the brain and nervous system. Adults can also experience health effects from lead exposure, such as high blood pressure and kidney problems.
3. Dust and Deterioration: Lead paint becomes hazardous when it deteriorates, chips, or turns into dust. This can happen during home renovations, repairs, or simply as the paint ages. Lead dust can settle on surfaces and be easily ingested or inhaled, especially by children.
4. Soil Contamination: Lead from exterior lead-based paints can contaminate the soil around your home. Children playing in contaminated soil or bringing it indoors on their shoes can be at risk.

Should You Test for Lead?

If your home was built before 1978 and you suspect lead-based paint, it’s a good idea to have a professional lead inspection or risk assessment. Certified inspectors can check the presence of lead in paint, dust, and soil, and determine if it poses a hazard.

Lead Hazard Management:

If lead is detected, options for managing it include:

• Encapsulation: Covering the lead-based paint with a special sealant.
• Enclosure: Covering surfaces with new drywall, paneling, or siding.
• Removal: Having a professional safely remove the lead-based paint.
• Ongoing Monitoring: If the lead-based paint is in good condition, it might not pose an immediate risk, but regular monitoring is essential to ensure it doesn’t deteriorate.

In conclusion, if your home is older or if you’re planning renovations, it’s important to assess the potential for lead hazards and take steps to address them for the safety of your family.
