Water Damage Evaluations

Have you had a pipe break? An appliance leaking? Or did you have flooding or a roof leak resulting from a hurricane? We can come in to inspect the areas damaged and provide evidence to the extend of the damage, confirm that all moisture levels are at normal levels, and look for evidence of mold propagation. The assessment will let those working on restoring the property know exactly what needs to be done to fully restore the building. All of our assessments are customized to meet your needs, but a general guide is listed below. 

Anatomy of an Assessment

Visual Inspection

A visual inspection is the most important initial step in identifying a possible contamination problem. The extent of any water damage and mold growth should be visually assessed. This assessment is important in determining remedial strategies. Ventilation systems should also be visually checked, particularly for damp filters but also for damp conditions elsewhere in the system and overall cleanliness. Ceiling tiles, gypsum wallboard (sheet rock), cardboard, paper, and other cellulosic surfaces should be given careful attention during a visual inspection. 

Laboratory Sampling

An expert will collect samples for laboratory analysis. These may include:


Air Samples: The investigator collects samples of the air to determine if hidden sources of mold are present in the building. The simplest type is called “spore trap technique” in which a known quantity of air is drawn across a sticky surface. Spores in the air adhere to the sticky surface. 

 

Bulk/Surface Sampling: A piece of the building material or furnishing suspected of housing mold growth is cut out and sent to a laboratory. The sample can either be inspected under a microscope or cultured in a growth medium. Bulk samples are usually collected from visibly moldy surfaces by scraping or cutting materials with a clean tool into a clean plastic bag. Surface samples are usually collected by wiping a measured area with a sterile swab or by stripping the suspect surface with clear tape. Surface sampling is less destructive than bulk sampling. 

 

Dust Collection Samples: Samples of settled dust are sometimes collected to see how much and what types of fungi are in the dust. 

Tape Lift Sample: A piece of cellophane tape is placed on a surface containing discoloration that is suspected to be mold. A trained mycologist using a microscope is a laboratory can confirm the sample. 

 

Wipe or “Swab” Samples: The investigator wipes a smooth surface with a cotton swab which is then placed in a growth media.
 

Air Monitoring

Air sampling for fungi should not be part of a routine assessment. Since decisions about appropriate remediation strategies can usually be made on the basis of a visual inspection. In addition, air-sampling methods for some fungi are prone to false negative results and therefore cannot be used to definitively rule out contamination. 

Assessments we offer:

Limited Assessment

Can be done with or without a protocol report. Price determined based on square footage and scope of work.

Full Assessment

Includes full protocol report with removal recommendations. Price determined based on square footage and scope of work.

Post Remediation Verification

Post remediation verification is testing performed after water damaged and mold infected materials have been removed. 

All assessments may include the following:

  • Visual inspection of all common areas of concern for any evidence of mold, contamination and water intrusion.

  • Exterior inspection (if applicable)

  • Cause of origin if not already known

  • Humidity and Temperature readings

  • Moisture readings (interior and exterior)

  • Moisture mapping

  • Thermal imaging with standard infrared camera

  • Inspection of HVAC system (if applicable)

  • Investigation and assessment of other known irritants and pollutants (if applicable)

  • Supporting photographs

  • Recommended filters and accessories

  • Preventative maintenance check list

  • Supporting laboratory reports (if applicable)
