Women -air qaulityOrdering a FULL MOLD Inspection with air samples is important if you suspect that a MOLD problem exist due to a musty smell, visible evidence of apparent MOLD growth or if conditions exist for MOLD growth in multiple locations of your home and can not determine the source.  Mold spores are not visible to the naked eye, however the types of mold present can often be determined through laboratory analysis of the air samples.  Having samples analyzed can also help provide evidence of the scope and severity of any mold problem, as well as aid in assessing human exposure to mold spores.

Air samples can be used to gather data about mold spores present in the interior of a house.Pump2  These samples are taken by using a pump that forces air through a collection device which catches mold spores.  The sample is then sent off to a laboratory to be analyzed.

Air Samples are generally recommended if visual, non-invasive examination reveals apparent mold growth or conditions that could lead to growth, such as moisture intrusion or water damage.  Musty odors can also be a sign of mold growth.  If no sign of mold or potential for mold is apparent, then a FULL MOLD Inspection may not be necessary,however a Home buyers or Homeowner may still want to order one or two indoor air samples in the most lived-in room of the house or at the HVAC unit or Air ducts as a safety precaution or just Peace of Mind.

Our FULL MOLD Inspection and Air Quality sampling for Mold includes two outdoor air samples and four Interior samples. Outdoor samples are taken as a control for comparison to indoor samples. Two Outside samples — one from the windward side and one from the leeward side of the house — provides a more complete picture of what is in the air that may be entering the house through windows and doors at times when they are open.

The FULL MOLD Inspection &  Air Sampling package includes FOUR interior samples in the areas of concern or primary living or sleeping areas. If other areas of a house are suspected or confirmed to have mold growth, additional air samples can be taken to help verify and gather more information.  Moisture intrusion, water damage, musty odors, apparent mold growth, or conditions conducive to mold growth are all common reasons to gather an air sample.  Normally, samples are taken near the center of the room, with the collection device positioned 3 to 6 feet off the ground.

Sampling is recommended to take place in livable spaces within the house under closed conditions in order to help stabilize the air and allow for reproducibility of the sampling and measurement.  While the sample is being collected, we ask that windows and exterior doors be kept shut other than for normal entry and exit from the home.

Weather conditions can be an important factor in gathering accurate data. Severe thunderstorms or unusually high winds can affect the sampling and analysis results.  High winds or rapid changes in barometric pressure increase the difference in air pressure between the interior and exterior, which can increase the variability of airborne mold-spore concentration.  Large differences in air pressure between the interior and exterior can cause more airborne spores to be sucked inside, skewing the results of the sample. In the event the above conditions exist, we will reschedule the air sampling for another day.

Difficulties and Practicality of Air Sampling

Ordering a FULL MOLD inspection with Air samples is a good start, however sometimes an air sample alone is not enough to confirm or refute the existence of a problem, and such testing needs to be accompanied by other methods of data collection, such as a surface sample. SPore 2

Air samples are good for use as a background screen to ensure that there is not a large source of mold not yet found somewhere in a home.  This is because they can detect long chains of spores that are still intact. spo These chains normally break apart quickly as they travel through the air, so a sample that reveals intact chains can indicate that there is mold nearby, possibly undiscovered during other tests and visual examination.

In summary, when taken under controlled conditions and properly analyzed, air samples for mold are helpful in comparing relative particle levels between a problem and a control area.  They can also be crucial for comparing particle levels and air quality in an area before and after mold remediation.  Please note that our Inspection and Air Quality evaluation is for Mold and other airborne contaminates and not an Allergy or Allergen evaluation.

SPECIAL INTRODUCTORY OFFER! (Not offered as an Add-On-   This is not a Home Inspection but a separate Full Mold Inspection)

Our FULL MOLD INSPECTION & Air Sampling package is a separate full Mold Inspection offered at $795 for the inspection and six air samples (4 indoors & 2 outdoors) which includes all lab fees.  Additional air samples or surface samples are available at $65 each.  Lab results are available within  48 to 72 hours from drop off or mail delivery and e-mailed as a PDF file to the client the same day of receipt.    In most cases… a Full Mold Inspection may not be necessary if concerns are general or can be defined to a particular area of concern. Other more affordable options are available by ordering a LIMITED Mold Inspection which includes two Air samples.Our Limited Mold Inspection is available as an Add-On to your Full Home Inspection or available as a stand-a-lone inspection. Additional air or surface samples can be ordered for just $55 each which includes all lab fees.
