Mold Inspection Process

testingandinspection

Mold inspection and mold testing are designed to help clients discover, document, and understand mold related issues through professional investigation, testing, and analysis methods in conjunction with proven sampling strategies (e.g., microscopic vs. culturable analysis, culturable & non-culturable air sampling, surface sampling, tape lift sampling).

Such mold & toxic mold inspection, clearance testing, and analysis must be accomplished with an effective chain of custody, meeting outlined and proven transport requirements. In the end, all findings must be reported to the client in a professional manner. Only the results of building material moisture surveys, boroscopic examination (if necessary) of wall cavities, and laboratory results can accurately define a mold problem.

The following are some of the potential property conditions which warrant a professional mold inspection:

Mold-Inspections4

Frequent Condensation on Window

Cause: improper window seal, moisture retention inside wall cavities, temperature-humidity regulation.

Consequence: moisture seeps past window frame and into wall cavity causing water damage and mold growth inside wall.

Surface Mold On Window Seal

Cause: improper window seal, moisture retention inside wall cavities, temperature-humidity regulation.

Consequence: moisture seeps past window frame and into wall cavity causing water damage and mold growth inside wall.

Roof Leak

Cause: damaged or improperly installed shingles.

Consequence: water damage and mold growth spreading under shingles and eventually ending up in attic and interior construction materials.


Mold Inspection Process

  • Typically 2 certified technicians are sent to the property to do a full five point inspection, visual, and manual assessment.
  • Air samples taken check if there is mold in the air and swab samples to check if there is mold on surfaces. Then check for possible water intrusion points that may lead to mold and take non-invasive moisture level measurements.
  • Photographs of mold specimen sources are taken and attached to a “Chain of Custody” document; a procedure compliant with legal standards for evidence. Additionally, particle counters in and outside your home help to determine the amount of negative particles that are in elevated indoor levels as compared to the outside.
  • Use of infrared camera technology to clearly show mold that may be growing behind walls and moisture readers to detect moisture damage to drywall, insulation and other materials in your property.
  • Within 2-3 business days, a detailed report of the lab results should be compiled. This report will advise on (1) whether there is mold; (2) severity of the mold growth rate; (3) the recommended remediation steps to remove the mold; and (4) instructions to prevent mold from reoccurring along with infrared photos of your property.

The cost of comprehensive inspection varies by region. Testing should include air testing, swab sampling, water intrusion inspection, moisture level measurement, photographs of mold sources, internal/external mold particle comparison, infrared technology for hidden mold detection and damage assessment, and a detailed report summarizing lab results as well as recommended curative steps. 

Goals of Mold Investigation

Mold-Inspections-why1 

  • Determine if there is a mold or toxic mold infestation problem
  • Determine the cause of the mold or toxic mold infestation problem
  • Determine the extent of the mold or toxic mold infestation problem

Types of Mold Testing

  • Air Testing using Air Cassettes
  • Wall Check Cassettes
  • Carpet Check Cassettes
  • Bulk, Swab & Wipe Samples
  • Tape Lift Samples
  • Clearance Testing

The 3 Most Common Types of Sampling:

  • Surface samples (testing mold growth on surfaces)
  • Air samples (testing airborne mold spores)
  • Dust samples (mold DNA analysis)

Purpose:

  • Identify the type of mold present
  • Quantify the level of mold present
  • Confirm or rule out the probability that mold is originating from a suspect condition indoors
  • Assess the potential for property damage caused by mold without invasive procedures
  • Assess the potential negative impact of mold on indoor air quality

Mold often grows behind walls and inside ceiling and floor cavities long before it is ever detected. By the time you start smelling an unpleasant odor, rest assured mold has been growing somewhere for some time and every day is growing more. If you suspect you have mold growing indoors, the time to act is sooner rather than later.
