Mold Surveys

Mold Surveysback
profile
Identification of the source and the extent of the microbial contamination problem are critical in developing a successful remediation plan. We document, manage, and verify microbial remediation projects to ensure the work is completed successfully.
Service Offerings
  • Base Line Mold Surveys (viable or non-viable air surface and air sampling available)
  • Scope of Work for Microbial Remediation
  • Sewage Backflow Assessment, Remediation Protocols & Post Remediation Verification
  • Remediation Project Management and Sampling Services
  • Pre-remediation Contamination Identification
  • Post-remediation Removal Confirmation
  • Design, Construction and Renovation Consulting Services
Our Investigation Procedures
  • Assess as practically possible the buildings structure, document both indoor and outdoor environmental conditions and interview occupants for concerns that may or may not be related to a potential mold concern.
  • Create an effective sampling strategy following current industry sampling guidelines. (see the references below)
  • Perform a visual investigation of building components such as HVAC, sump pumps, air exchange systems, etc. We will perform intrusive methods only where required such as when both visual inspection and laboratory results suggest presence of hidden mold growth. We have a team of contractors who can provide a cost estimate for the replacement of any materials removed during intrusive investigations.
  • Test and document the following conditions:
    Moisture content in building materials.
    Relative humidity, Equilibrium RH of building materials, Dew Point, and Temperature of the outside environment and compare it to the indoor environment.
    Collect bulk, air, swab, and tape samples for mold and/or other hazardous materials such as Asbestos. Only samples that are relevant to the investigation being conducted will be collected.
    Determine the area of suspect mold-contaminated and or hazardous materials.
  • Photograph each sample taken as well as all of the above mentioned atmospheric conditions.
  • Prepare a detailed report which includes, lab test results, lab test results interpretation by Dr. Jackson Kung’u PhD; along with our added comments, photographs, conclusions, recommendations, and a scope of work, and at your request we can provide a cost estimate to remediate the mold concern.
