Mold Frequently Asked Questions & Testing Procedures

Why is mold growing in my home?

Molds are part of the natural environment.  Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided.  Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air.  Mold may begin growing indoors when mold spores land on surfaces that are wet.  There are many types of mold, and none of them will grow without water or moisture.

Can mold cause health problems?

Molds are usually not a problem indoors, unless mold spores land on a wet or damp spot and begin growing.  Molds have the potential to cause health problems.  Molds produce allergens, irritants, and in some cases, potentially toxic substances.
Allergic reactions to mold are common and include hay fever-type symptoms, such as sneezing, runny nose, red eyes, and skin rash.  Molds can also cause asthma attacks in people with asthma who are allergic to mold.

How can I determine if mold is in my home?

Mold spores will not grow without water or moisture. Identifying areas of moisture are key to preventing mold growth inside of your home.

Our state-of-the-art infrared thermal imaging technology provides a visual footprint of moisture at the walls and ceiling of your home by identifying the differential temperature changes on the surface of the building materials, which helps locate the wet areas within your home. Many times these areas go unseen because they are invisible to the naked eye. The combination of this technology with the use of moisture meters, visual inspection and mold testing equipment provide the lastest advancements in testing procedures.

What to do if you suspect that your home has mold?

 

Get a Professional Mold Assessment of your house. By surveying moisture levels of walls, ceilings and floors, locating visible mold growth, and testing the air for the quantity and variety of mold spores. Determining the variety of mold is important because some types of mold are indicators of water damage and are potential health hazards.

How is the air tested?

 

Indoor Air 

It is primarily these samples that determine airborne mold spore counts. Proximate outdoor air is also tested (for the control sample) For reliable results, the equipment used includes a controlled volume air pump, which draws air through Z5 spore trap cassettes. After the air samples have been performed the Z5 cassettes are shipped FedEx overnight to an accredited microbiology laboratory for microscopic examination and analysis. Typical turnaround is 48 hours.

 

Wall Interior Air

Infrared thermal imaging and moisture meter readings of an elevated moisture content of the wall material make it a candidate for this type of testing; especially when it is drywall (the paper covering is vulnerable to consumption from mold growth). Samples are collected using the WallChek® system, providing an adapter for Z5 spore trap cassette, and utilizing small ¼ inch tubing, which is inserted into the wall. Air sampling pumps draw air from the wall cavity to obtain the mold spore count within the wall cavity.
