Mold Assessments and Mitigation

Mold: A Silent Disruptor

Mold is a silent disruptor, often appearing when business owners and building occupants least expect it. As the most common form of fungi on earth, mold and mold spores are ever present in both the outdoor and indoor environments making them difficult to eliminate.


When mold spores land on moist surfaces indoors, they can begin to grow, digest the surface, and cause damage that can be costly to repair and cause adverse health effects.  Preventive action through moisture control is the only known method to stop the spread of mold in indoor environments.


The Certified Industrial Hygienists (CIH) and Industrial Hygiene Technicians at CMI have addressed mold contamination in various settings including commercial, industrial, governmental, and educational buildings. Our trained professionals will help identify and oversee mold remediation in your building. 

Factors Impacting Mold Growth

Mold needs a food source in order to live and multiply. Unfortunately, food sources are plentiful and found in common building materials such as wood, drywall, and paper, as well as plants and organic matter. Below are other common building materials where mold can grow:

  • Carpet,
  • Ceiling tile,
  • Insulation,
  • Wallboard,
  • Wood,
  • Paper,
  • Surfaces behind wallpaper,
  • or in heating, ventilation, and air conditioning (HVAC) systems.

In order for mold to grow, the conditions must be just right. They thrive in warm and wet environments with a continuous water source such as roof or water leaks, HVAC condensate pans or cooling towers, damp basements, and areas with high humidity such as shower areas and non-conditioned spaces. The more favorable the conditions, the faster mold will grow.

The most common sources of moisture within a building are those where moisture is most prevalent: plumbing, roofing, window leaks, flooding, condensation on cold surfaces like pipe sweating, poorly maintained drain pans from the HVAC system, and wet foundations due to landscaping or gutters that direct water into or under a building.


In schools, mold can most likely be found in roofs, walls, locker rooms, kitchens, bathrooms, and any other area where moisture collects. Since schools are often sealed during the summer months, excess humidity can also lead to mold growth during this time.

Why Building Owners and Facility Managers Should Be Concerned

Structural damage to buildings from mold growth, odors, and health effects in occupants or workers are all concerns when mold is present. Structural damage is caused when moisture is not controlled and fuels the growth of mold on building materials, finishes, and furnishings. Mold is ever present and will only need the perfect conditions for a short period of time to grow.

If there is a large amount of mold present in a building, odors and allergic reactions can also be present. Good indoor air quality is crucial to the health and well-being of building occupants, especially children who spend a majority of their time in school buildings. In fact, providing good indoor air quality (absent from odors caused by mold and particulate matter) falls under the general duty clause from the Occupational Health and Safety Association (OSHA) which states employers are required to provide a safe and healthy work environment.

Health Effects from Mold

While most people are familiar with mold growing on surfaces, mold is ever present in the air as it releases countless tiny, lightweight spores which travel through the air and help it multiply. These microscopic organisms are present both indoors and outdoors. Extensive indoor mold contamination can cause high and persistent airborne spore exposures leading to allergies, respiratory illnesses, and other health problems.

Though all individuals act differently to indoor mold exposure, the most common health effects and symptoms according to the Center for Disease Control (CDC) include:

  • Asthma
  • Wheezing
  • Allergic reactions
  • Nasal stuffiness
  • Eye irritation
  • Skin irritation

For some building occupants, a relatively small number of mold spores can trigger a respiratory episode while others take an infestation to show symptoms.

Choosing the Right Environmental Health Consultant

Most people decide to test for mold after smelling an unusual odor, seeing discolored spots, or becoming sick for no apparent reason. Since mold growth is often caused and accelerated by moisture, many businesses test after a significant water-related property issue: heavy rain, pipe burst, flooding, and in the heat of summer with poor moisture control. Testing before remediation helps establish a baseline while testing after ensures mold has been properly mitigated.

CMI is one of the premiere mold testing companies for commercial, educational, and industrial clients, and can help property managers, facility managers, and school administrators determine the best course of action for mold remediation including preventive measures before the mold has a chance to become a problem.

We have over 25 years of experience assisting architects, developers, building owners, school administrators, and property managers with ensuring Indoor Air Quality (IAQ) is conducive to a safe, healthy, and comfortable environment. Our experienced technical team of Certified Industrial Hygienists (CIH) and Industrial Hygiene field staff work closely with clients to assess, mitigate, and develop remediation plans for IAQ concerns, including mold.

We assist commercial and industrial clients to proactively manage occupational health and illness prevention programs.

Project Profiles

State and Local Government

CMI personnel provided this government entity with environmental, health, and safety consulting services.  The services included asbestos and lead inspections, abatement specifications, and the management of asbestos and lead abatement projects.  In addition, CMI personnel also performed mold and moisture investigations of the residential units.  The mold and moisture investigations included visual inspections, the collection of air and surface samples,  determining the cause of mold growth, and developing bioremediation protocols.

School Districts and Universities

CMI works with many school districts including one with mold growth on pipe insulation in the Middle School pipe tunnels. CMI conducted area air sampling for mold spores to evaluate the potential health risks in the building. In conjunction with the testing activities, CMI performed a visual inspection of the pipe tunnels to identify the extent of mold contamination. We also prepared a professional report with sample results, findings, conclusions, and recommendations.  We even assisted the school in soliciting and reviewing bids for the remediation.  During the remediation CMI provided oversight of the contract to ensure that work was performed safely and in accordance with the specification.  At the conclusion of the remediation CMI prepared a detailed final report for the District.

Real Estate and Property Managers

This real estate developer and property manager contacted CMI for an indoor air quality assessment that lead to the discovery of mold and a leaking HVAC system. CMI was able to create a mold abatement program, help solicit bids for mold remediation, and routinely checks indoor air quality to maintain the comfort of tenants.
