Home Investigations

The first step in beginning an investigation is to interview the homeowner. There is the need for specific information from the homeowner before an investigation begins. This information will give a background of the day-to-day living arrangements of the household occupants. Without correct answers, the investigation would be of little use to those residing in the home. The information deals with the condition of the house itself along with any damage or remodeling that has transpired. The type of heating and air-conditioning system will also be noted. Most importantly, the ongoing health and age of the occupants is needed to come to a helpful resolution to the problem that is under investigation. At the bottom of this page is a basic questionnaire defining the information generally needed from every homeowner.

After the interview, particulate tests will be done throughout the home to get a general idea of the amount of particles in the air (see Testing Equipment ). A particulate test will also be done outside as a comparison because generally the outside air has more particles in it. During the particulate testing, an overall assessment of the structure of the home will be done. Any past or present water damage signs will be noted. If there is visible mold growth, the source of the moisture contributing to that mold growth will be checked. This may mean a look in the attic and basement or crawl space.

Moisture testing of building materials will be performed using a Delmhorst Moisture Meter:

• Check moisture in drywall, insulation, wood, concrete, and plaster.
• Trace leaks and find exterior moisture, and locate dry rot.

If mold tests are indicated two different tests which can give a picture of airborne contaminants will be considered and discussed with the householder. These tests will be taken in several areas, generally those where individuals are experiencing health problems and one non-problem area. This will give an excellent overall evaluation of the home at that time. There will also be tests taken on the outside for comparison purposes. The first test is generally taken with the Andersen air-sampling machine (see Testing Equipment) followed by a Zefon air sampler (see Testing Equipment). The Andersen air sampling tests will be sent to a lab where they will be incubated for seven days. The growth on the plate will be checked by electron microscope at three days and again on the seventh day. The results will be sent to us with a comment page telling the pathogenicity and quantity of airborne contaminants. The Zefon samples will be checked under a microscope to identify the particles collected.

Swab or tape samples may be taken from the air ducts and any visible mold growth. These also will be sent to the lab to be cultured or viewed under a light microscope to determine the contaminant(s).

If an odor or chemical smell is the problem a VOC Meter will be used to determine if there is a source within the home or business that may be emitting VOCs (volatile organic compounds). To find a specific VOC (i.e. formaldehyde) a test designated for that compound will need to be done.

After the report from the lab is received, a written report containing Indoor Air Services evaluation, the lab report and any recommendations, if necessary, will be emailed to the homeowner. The homeowner may call with any questions about this report. If remediation is necessary a Remediation Protocol can be requested.

FAQs

1. Is mold dangerous?
Certain molds can effect the health of individuals, especially those with respiratory health problems and individuals who are immuno-compromised.

2. What are the symptoms for mold exposure?
Some symptoms are headaches, lethargy, nose bleed, difficulty in breathing, brain fog, cold or flu-like symptoms.

3. Should I move out of my house?
Generally this is not necessary unless there are some extenuating circumstances, which must be determined in each individual case by a physician.

4. What steps can I take to improve the indoor air quality in my home?
