Mold Testing

Mold is a type of fungus that exists almost everywhere, thriving in places with excessive moisture. If you spot mold growing inside your home, it's a clear indication of an underlying water or moisture issue.

It is crucial to first fix the cause of the moisture, and then obtain a comprehensive mold sample test to detect the extent of the growth. At NextDay Inspect, we utilize advanced testing for common indoor mold types including Cladosporium, Penicillium, and Aspergillus.

NAMRI Certified. Trained to set identical professional standards in mold testing.

Accuracy in Every Detail.

To ensure your mold test is pinpoint accurate, there are vital steps we prepare for and closely monitor throughout the property.

Air Or Swab Sample

We provide both air and swab samples. Black spots? A swab sample is best. High airborne spore concerns? Air samples determine if an area has enough mold to encourage growth.

Moisture Susceptibility

Mold is naturally attracted to moist environments like basements and bathrooms. This means spores are significantly more likely to settle and grow in these areas unchecked.

Closed Conditions

For maximum accuracy during tests, we keep the indoor environment within usual conditions. Readings will be skewed if windows and doors are left open during the testing.

Control Comparison

To determine dangerous elevations of spores, a exterior control sample must be taken to compare against the interior environment, isolating the property's actual mold growth.

Health Effects of Mold

Microscopic mold spores rapidly absorb airborne moisture to expand across surfaces. Prolonged exposure presents severe risks, especially for those with existing respiratory conditions.

Do I Have Mold?

Recent water leaks or persistent moisture issues almost certainly lead to rapid mold development. Early detection via professional sampling prevents massive repair costs and dangerous structural spreading.

Where Can Mold Hide?

Mold thrives in dark, humid, and undisturbed microclimates. Identifying these high-risk hidden zones is the crucial first step toward securing your home.

01
Behind the Refrigerator

Behind the Refrigerator

Due to the cooling nature of your refrigerator, atmospheric moisture may rapidly condense against nearby walls. This dark, undisturbed space is an ideal breeding ground and a critical first place to check.

02
Behind Drywall

Behind Drywall

Areas previously subject to leaky pipes or flooding trap ambient moisture directly inside porous drywall, allowing structural rot and mold to bloom completely hidden from plain sight.

03
Window Wallboards

Window Wallboards

As a primary thermal bridge where exterior heat and rain penetrate, frequent condensation makes the gypsum wallboard surrounding window framing exceptionally prone to water damage.

04
Ventilation Ducts

Ventilation Ducts

Improperly sealed ducts allow trapped condensation and humid vapors to stagnate. Circulating HVAC systems then effectively distribute these enclosed spores throughout the entire household.

05
Under Carpeting

Under Carpeting

Flooring padding eternally traps moisture after significant water intrusion. This dark, highly compressed microclimate creates the perfect damp environment for aggressive subsurface growth.

06
Attic Paneling

Attic Paneling

Trapped humidity in stagnant, unventilated attic zones guarantees rapid spore colonization across underlying wood paneling. Repairing an initial roof leak is only the first phase of addressing an attic outbreak.

Diagnostic Capability

Precision Sampling Methodology

We deploy rigorous laboratory-grade sampling techniques to isolate, identify, and quantify organic growth hiding throughout your property.

Air Sample

Air samples will be taken in the primary area and additional areas if requested. Laboratory analysis will conclusively indicate if there is a presence of mold growth and detail the types and amount of mold spores in the air.

Swab Sample

Swab samples can also be taken of visible growth on surfaces. Laboratory analysis will strongly indicate whether or not there is growth, and provide precise details on the specific type and amount of the mold.

Species Directory
High-Risk Indoor
Secondary Screening
Additional Particulates
High-Risk Allergen

Aspergillus / Penicillium

Statistically the most frequent indoor mold strains found in water-damaged homes. They rapidly colonize damp wallpaper, carpet fabrics, and HVAC systems, releasing dense concentrations of allergenic spores directly into the home's circulating airflow.

Primary Habitat HVAC, Drywall, Damaged Fabrics
Clinical Threat Aggravates Asthma & Allergies
Toxic Threat

Stachybotrys / Memnoniella

Infamous to the public as "toxic black mold". This dangerous pathogen requires constant, prolonged moisture to breed. It violently metabolizes high-cellulose structural materials like drywall, ceiling tiles, and structural wood framing.

Primary Habitat Saturated Drywall, Wet Wood
Clinical Threat Produces Harmful Mycotoxins
Moderate Allergen

Cladosporium

Highly prominent in inherently humid residential environments. This strain is frequently found spreading aggressively across cold surfaces subject to condensation, such as window sills, damp carpet padding, and uninsulated walls.

Primary Habitat Window Sills, Condensation Zones
Clinical Threat Triggers Respiratory Issues
Aggressive Grower

Alternaria

A naturally fast-spreading outdoor mold that successfully establishes massive, dark-colored colonies indoors within chronically damp areas. It is notoriously prevalent in leaking standing showers or previously flooded basements.

Primary Habitat Showers, Flooded Basements
Clinical Threat Heavy Allergen Emitter
Structural Threat

Chaetomium

Typically discovered aggressively deteriorating severely water-damaged drywall and baseboards. This specific genus is responsible for producing the distinct, aggressively "musty" odor characteristic of wet basements.

Primary Habitat Rotted Baseboards, Wet Drywall
Clinical Threat Structural Rot & Noxious Odors
High-Moisture Pathogen

Fusarium

An opportunistic pathogen requiring exceptionally wet conditions to survive. In residential properties, it is frequently isolated near active, ongoing plumbing failures, heavy humidifier usage, or areas of standing black water.

Primary Habitat Active Plumbing Leaks
Clinical Threat Toxic to Human Systems
Routine Screen

Ascospores

Widespread outdoor spores heavily released during damp or rainy weather. They frequently blow indoors via open windows or are carried inside by residents.

Routine Screen

Basidiospores

Typical wood-rotting fungi originating from decaying outdoor trees. They infiltrate interior residential environments via wind infiltration or foot traffic.

Indoor Survivor

Bipolaris

A plant pathogen that thrives on dead vegetation outdoors, but proves capable of surviving indoors by feeding off soft, water-damaged organic materials.
