The Importance of Mold Testing in Your Home: Insights from a Home Inspector

Mold testing plays a crucial role in maintaining a safe and healthy home environment. As a home inspector, I recommend mold testing to uncover potential issues that may not be immediately visible. Here’s why mold testing is important.

Why Mold Testing is Important

Health Risks

Mold exposure can lead to various health problems, including respiratory issues, allergic reactions, and worsening of asthma. Identifying and addressing mold early can prevent these health risks and ensure a safer living environment.

Hidden Mold

Mold often grows in hidden areas, such as behind walls, under floors, or within HVAC systems. These hidden colonies can cause significant damage over time if left undetected. Mold testing helps uncover these hidden issues before they escalate into more serious problems.

Property Value

A home with undetected mold can lose value. Potential buyers may be deterred by mold issues, which can lead to reduced marketability and financial losses. Mold testing provides a clear understanding of any issues and helps maintain the value of your property.

Insurance and Liability

If you’re selling your home, undetected mold can lead to disputes or insurance claims from new owners. Mold testing provides documentation of the home’s condition, protecting you from future liability.

What is Mold Testing?

Mold testing involves collecting samples from the air and surfaces in your home to identify the presence and concentration of mold spores. Here is a brief overview of the process:

1. Visual Inspection
   A thorough visual inspection is conducted to identify any signs of mold or conditions conducive to mold growth, such as water damage or high humidity.
2. Air Sampling
   Air samples are taken from various areas of the home to measure the concentration of mold spores. This helps identify whether mold is present in areas that are not visible during the inspection.
3. Surface Sampling
   Swabs or tape lifts collect samples from surfaces where mold growth is suspected.
4. Laboratory Analysis
   The collected samples are sent to a laboratory for analysis to identify the types and concentrations of mold present.

A comprehensive list of the organisms that our lab can detect.

Predominantly Indoor Water-Related

The spores listed below the section “Predominantly Indoor Water Related” are spores which are not expected appear in the outdoor air commonly. Presence of these spore types indoors can be a strong indication of water damage, even at low levels.

	Aspergillus/Penicillium Chains	Aspergillus/Penicillium spores appearing in attached chains can be indication of nearby fungal growth. Typically, airborne Aspergillus/Penicillium spores from the outdoors will separate and appear on air samples as individual spores.
	Chaetomium	Water damage indicating mold that can be found on damp building materials such as drywall, paper, and wood. Some species can produce mycotoxins.
	Clado-Sphaerospermum	A specific species of Cladosporium that can be reliably identified visually and which requires more moisture to grow. This allows it to be a suitable indoor water-damage-indicating mold.
	Fusarium	A common plant pathogen that may also impact very wet building materials and humidifiers indoors. Other indoor sources may be molded fruits. Some species may produce mycotoxins.
	Gliomastix	An uncommon mold occasionally recovered from water-damaged building materials. Toxicity and human health effects not known.
	Scopulariopsis	A naturally occurring soil fungi that can also grow on water-damaged building materials. Scopulariopsis has a similarly high water activity as Stachybotrys.
	Stachybotrys	A sticky, pigmented spore that can grow on cellulose containing building materials such as paper and wood. Due to the sticky nature of these spores, hidden, undisturbed growth may be difficult to detect with routine air sampling. Stachybotrys has been referred to as “toxic black mold” in the media; however the specific health effects from exposure to Stachybotrys has not been established and is still the subject of ongoing scientific research. Some species can produce mycotoxins.
	Ulocladium	Water damage indicating mold, can be found in outdoor air samples. Spores may be confused with Alternaria or Pithomyces. Major allergen.
	Wallemia	Wallemia is a xerophile that can grow on relatively dry surfaces. Can be found growing on exposed wood and in house dust.

Indoor/Outdoor

The types of mold that appear under the section “Indoor/Outdoor” are types which can be found frequently in the outdoor air, but also can be found growing on building materials indoors. The presence of these types of mold indoors is not always an indication of water damage, concentrations should be compared closely to outdoor reference samples.

	Alternaria-like	A common outdoor mold that may also be found growing on damp building materials. Can be an opportunistic human pathogen, and some species may produce mycotoxins.
	Aspergillus/Penicillium	Aspergillus/Penicillium an aggregate group of spores that are reported together due to the common morphology found amongst these spores. In non-cultured samples, a more specific identification can not be made without additional structures such as condiaphores. Aspergillus and Penicillium one of the most common outdoor molds, but can also be found growing on water damaged building materials indoors. Some species may also grow in properties with chronic humidity issues. Some species may produce mycotoxins. Some species may be potential human pathogens.
	Cladosporium	One of the most common molds in the world, ubiquitous outdoors but also found in high concentrations in water damaged buildings.

Predominantly Outdoor

“Predominantly outdoor” molds are types that are found naturally in the outdoor environment, which do not readily grow on building materials indoors.

	Arthrinium	Generally an outdoor mold, but on occasion can be found growing on damp cellulose building materials.
	Ascospore	The Ascospore group represents a very large group of fungal spores that are produced by Ascomycota, otherwise known as Sac fungi. This group is generally represented by unimportant spore types that most likely originate from the outdoors. Spores from specific Ascomycota of note, such as Chaetomium, are reported separately and are not included in this report group.
	Basidiospore	The Basidiospore group represents the group of spores produced by Basidiomycota. Basidiomycota includes many macrofungi such as mushrooms, puffballs, brackets, and more. Basidiospores found indoors nearly always originate from the outdoor environment.
	Bipolaris	One of the most common fungal allergenic agents. Plant pathogen and soil based fungi.
	Bispora	Mitosporic fungi that can rarely be recovered on damp wood materials.
	Botrytis	Plant pathogen found commonly on fruit.

	Chaetoconis	Plant pathogen
	Coelomycete	Asexual fungi that produce spores in fruiting bodies. Many are plant pathogens. Infrequently impact IAQ due to spores not being readily dissipated by air movement.
	Curvularia	Outdoor fungi that can rarely be recovered from water damaged fabrics.
	Epicoccum	Commonly found in outdoor air, uncommon growth on building materials indoors. Juvenile spores may be confused with Stemphylium, Alternaria, Pithomyces, or Ulocladium
	Exosporium	Plant pathogen
	Fusicladium	Agricultural pathogen affecting many different crops.
	Lasiosphaeria	Found on dead, decorticated deciduous trees throughout the world including Canada, Costa Rica (as L. chrysentera Carroll & Munk), Denmark, England, France, Germany, New Zealand, Philippines, Russia, Switzerland, and USA.
	Mitospore	A group of undifferentiated asexual fungal spores. These spores can be determined in being asexual spores, but can not be differentiated further.
	Myrothecium	An outdoor fungi that inhabits plant surfaces and soil, as well as the fruiting bodies of some mushrooms. This mold is extremely rare on building materials.
	Nigrospora	Common in the outdoor air, especially in warmer climates. Grows on plant material and soil and has an active spore dissemination.
	Oidium	Also known as “powdery mildew”, this fungi only grows on plants and does not affect building materials.
