Residential Mold TEsting

Air & Surface Sampling

If you want to confirm the presence of mold spores in your indoor environment without a full home inspection, our Mold Testing service offers professional air and surface sampling tailored to your specific areas of concern. This targeted testing is ideal for clients who need lab-confirmed results on what’s in the air or on surfaces but don’t require a comprehensive mold assessment.fullfufu

What Is Mold Testing?

Mold testing involves collecting air samples and/or surface swabs from areas in your home or business to identify and quantify mold spores. These samples are sent to accredited laboratories that specialize in mold identification to provide detailed reports of the types and concentrations of mold present.

Why Choose Mold Testing?

Mold Testing vs. Mold Assessment

While mold testing identifies what mold is present, a Mold Assessment is a comprehensive evaluation of the entire property. An assessment includes a visual inspection, moisture mapping, HVAC system evaluation, and strategic sampling to determine the source and extent of mold growth.

 

If you’re unsure which service fits your needs, we recommend our Mold Assessment service — it often provides a clearer picture for safe and effective remediation.

Different methods of sampling include:

Air Sampling

A specialized ‘Air Cassette” is used to collect mold spores in the air.

Cavity Sampling

A tube is inserted into a wall  cavity to draw air from between the space to collect mold spores.

Swab Sampling

Taking samples of any visible mold growth or suspected areas of mold growth along a surface

Tape Sampling

Using a piece of adhesive tape to collect mold spores from a surface.

Common Mold Types We Test For

Aspergillus

Aspergillus is a typical primary mold commonly found in environments with elevated humidity. It thrives in moist indoor areas where humidity levels are consistently high, often without obvious water damage. Aspergillus spores can cause allergic reactions and respiratory issues, especially in sensitive individuals.

Cladosporium

Cladosporium is also linked to humidity but usually indicates slight water damage or damp conditions. It’s one of the most common molds found inside HVAC duct systems due to condensation and/or poor ventilation. Its presence often points to persistent moisture problems that need addressing.

Water Damage Indicator Spores

These molds are considered tertiary molds and typically signal extensive water damage. Often referred to as “toxic black mold,” species like Stachybotrys and Chaetomium grow on wet, cellulose-rich materials after prolonged moisture exposure. Their detection usually indicates a serious moisture intrusion problem requiring immediate professional remediation.

Why Is Mold Testing Important?

Many people experience unexplained allergies, asthma flare-ups, or chronic respiratory symptoms without realizing mold exposure could be a factor. Mold spores are microscopic and airborne, making them invisible yet potentially harmful. Testing helps confirm the presence and types of mold — giving you data to decide if remediation or further assessment is needed.
