Mold Conditions

Condition 1 normal fungal ecology in living space. Currently there are no standards of quantity of how much mold spores indoors. Mold spores naturally occur in the air.

Condition 2 settled mold spores caused by disturbing mold colony.  Mold remediation with poor containment, and engineering controls can cause this issue. 

Condition 3 Unwanted mold growth causing decay, and damage to building materials, potential off gassing of mycotoxins, and endotoxins, and earthy musty odor.  

Mold requires certain conditions in order to grow and thrive. These conditions typically include:

  1. Moisture: Mold requires moisture to grow, and can thrive in areas with high humidity, water leaks, or condensation.

  2. Warmth: Mold typically grows best in temperatures between 60-80°F (15-27°C).

  3. Nutrients: Mold can grow on a wide variety of organic materials, including wood, paper, drywall, and fabrics.

  4. Oxygen: Like all living organisms, mold requires oxygen to grow and survive.

When these conditions are present, mold spores can begin to grow and multiply, leading to the development of visible mold growth and potential health problems. It is important to address any water damage or moisture issues in your home or building in order to prevent mold growth. Regular cleaning and maintenance can also help to control mold growth by removing any sources of nutrients and reducing moisture levels. If you suspect that you have a mold problem, it is best to seek professional help for proper mold remediation.



Flood Damage Categories

Flood categories refer to the level of water contamination and the potential health risks associated with flooding. There are three categories of floodwater:

  1. Category 1 (Clean Water): This is water from a clean source, such as a broken water supply line or faucet. It poses no substantial risk from ingestion, inhalation, or skin contact. However, it may become progressively contaminated as it mixes with soil and other contaminants.

  2. Category 2 (Gray Water): This is water that has a significant degree of contamination and could cause illness or discomfort if ingested, inhaled, or if it comes in contact with skin. Gray water may contain bacteria and viruses, as well as some chemicals.

  3. Category 3 (Black Water): This is water that is highly contaminated and could cause severe illness or even death if ingested, inhaled, or if it comes in contact with skin. Black water may contain sewage, chemicals, bacteria, and viruses.

It is important to note that even clean water can become contaminated if left standing for a prolonged period of time. Additionally, floodwaters can contain other hazards such as sharp objects, electrical hazards, and debris.

What are mold inspection techniques?

Mold inspection techniques involve a combination of visual inspection, air and surface sampling, moisture testing, and analysis. Here is a brief overview of each technique:

  1. Visual Inspection: A visual inspection is the first step in any mold inspection. The inspector will visually examine the property for signs of mold growth, such as discoloration, staining, and moisture damage. The inspector may also use specialized tools such as borescopes or thermal imaging cameras to examine hard-to-reach areas.

  2. Air Sampling: Air sampling involves taking air samples from inside the property and comparing them to outdoor air samples. The inspector will use a specialized air sampling device to capture mold spores that are present in the air. The samples are then analyzed in a laboratory to determine the type and quantity of mold present.

  3. Surface Sampling: Surface sampling involves taking samples from areas where mold growth is suspected, such as behind walls, under carpeting, or on surfaces that appear discolored or damp. The inspector will use a specialized tape or swab to collect a sample from the surface. The samples are then analyzed in a laboratory to determine the type and quantity of mold present.

  4. Moisture Testing: Moisture testing involves using specialized tools such as moisture meters, thermal imaging cameras, and humidity meters to detect areas of moisture that could be contributing to mold growth. Moisture testing can also help identify potential sources of moisture, such as leaks, high humidity, or poor ventilation.

  5. Analysis: Once the samples have been collected, they are sent to a laboratory for analysis. The laboratory will use specialized techniques such as microscopy, DNA analysis, and culture testing to identify the type and quantity of mold present. The results of the analysis are used to determine the extent of the mold problem and to develop a remediation plan.

Overall, a combination of these techniques is used in a mold inspection to identify the presence and extent of mold growth, as well as potential sources of moisture that could contribute to mold growth in the future. Mold inspection techniques are designed to be thorough and comprehensive, in order to ensure the safety and health of occupants of a property.

What does the HVAC system have to do with mold?

The HVAC (heating, ventilation, and air conditioning) system plays a significant role in indoor air quality and can contribute to mold growth if not properly maintained. Here are some reasons why the HVAC system can be related to mold:

  1. Moisture: The HVAC system can create moisture, which can contribute to mold growth if not properly controlled. Moisture can come from several sources, such as condensation on the cooling coils or from leaks in the ductwork. The presence of moisture can promote mold growth on or near the HVAC system.

  2. Airflow: The HVAC system is responsible for circulating air throughout the building. If the system is not functioning properly, it can create stagnant air pockets that promote mold growth. Additionally, the airflow can spread mold spores throughout the building, which can lead to cross-contamination.

  3. Filtration: The HVAC system filters the air to remove pollutants and allergens. If the filters are not changed regularly, they can become clogged and create a breeding ground for mold. Additionally, if the filters are not designed to capture small particles, mold spores can pass through and circulate throughout the building.

  4. Ductwork: The ductwork in the HVAC system can become contaminated with mold if moisture is present. If the ductwork is not properly sealed or insulated, it can create a favorable environment for mold growth. Additionally, if the ductwork is not cleaned regularly, mold can accumulate and spread throughout the building.

Overall, the HVAC system can contribute to mold growth if not properly maintained. It is important to have the system inspected and maintained regularly to ensure proper function and to prevent mold growth. Proper ventilation, humidity control, and regular cleaning and maintenance are key to preventing mold growth in HVAC systems.


What do we Investigate?

Indoor Air Quality Assessment

Mold is always a concern in Houston, TX due to its humidity, and weather events. However, an indoor air quality issue does not always involve mold. There are 2 things naturally in the air Gas/Vapor, and Particles. We want to know a number of things when it comes to an indoor air quality investigation. We conduct an indoor air quality assessment for a detailed, and thorough indoor air inspection. 

The indoor air should be cleaner than the outdoors since the indoors is a controlled environment. 

 Down below are metrics we look at to determine a healthy home, office, or building. 

  1. Ventilation-Is the indoors have good air exchange with the outdoor air without infiltration.
  2. Is the HVAC system performing properly keeping temperature, removing moisture, and particles from the air.
  3. Detecting levels of potential toxic gasses such as:
  • Carbon Monoxide
  • TVOCS 
  • Formaldehyde
  • Nitrogen Dioxide
  • Nitric Oxide
  • Ozone
  • Hydrogen Sulfide 

Measurements are taken by high tech instruments for every room, and closet in the home or office to track down issues without speculation.  Our investigation leads us in the right direction. 

Most times mold testing is unnecessary because mold growth is usually visibly seen. Hidden mold inside wall cavities are the most difficult to find. An indoor air quality assessment leads us in the right direction where to investigate. 

There are some cases where mold testing is necessary such as:

  • Mold Insurance Claims
  • Evidence 
  • Mold Identification 
  • Hidden Mold 
  • Air Conditioner Return/ Air Register
