There are many different types of inspections a mold inspector can perform on your home or business. The two most common types of inspections are: Air Sampling & Surface Sampling. Air Sampling is designed to capture and quantify a broad spectrum of fungal spores (both culturable and non-culturable) present in the air, and to assess […]
Alternaria is one of the most important allergenic molds found in the US. It is most common as an outdoor mold, as it thrives on various types of vegetation. Alternaria spores can be detected from Spring through late Fall in most temperate areas, and can reach levels of thousands of spores per cubic meter of […]
Molds are tiny, multicelled organisms made up of branching filaments called hyphae (singular: hypha). Some of the hyphae are embedded in the material on which the molds grow and are called vegetative hyphae. Many molds also have other hyphae, called aerial hyphae, which absorb oxygen from the air. Rhizoids, hairlike filaments resembling roots, grow from […]
Bulk Sampling is another technique used for direct examination. A direct exam allows for the immediate determination of the presence of fungal spores as well as what types of fungi are present. Direct examinations should only be used to sample visible mold growth in a contaminated area since most surfaces collect a mixture of fungal […]
Surface sampling is the most common technique used to test surfaces for mold during a mold inspection. It provides valuable information. The species of mold, the relative degree of contamination, and the potential for airborne spore production may all be determined by tape sampling. This method can be performed using either standard, clear cellophane tape or a […]
Taking air samples during a mold inspection is important for several reasons. Mold spores are not visible to the naked eye, and 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 a mold problem, as […]
There are may forms of mold testing that can determine whether or not your home or office has mold, and the severity of issue if one exists. The most common form of testing is Air Sampling, which basically traps spores in the air onto a sticky slide within a cassette that is mounted on top […]
Molds are microscopic fungi that live on plant and animal matter. Molds can be found almost anywhere when moisture is present. Molds create tiny spores to reproduce, just as plants produce seeds. Mold spores float through the indoor and outdoor air continually. When mold spores land on damp places indoors, they may begin growing. For people sensitive […]
Overview Non-culturable spore trap samplers draw measured volumes of air through the sampling device for a specified length of time. The collection surface is a coated glass slide. Particles in the air (spores, dust, etc.) impact onto the sticky surface and are “trapped” for later analysis. A general philosophy regarding the interpretation of biological air samples […]
There are other simple sampling methods that may be used to supplement volumetric air sampling. Surface samples are taken by tape lift imprint, by swabbing the suspect surface with a culturette swab, or by submitting a bulk sample of the suspect surface. We typically recommend that a direct microscopic examination be performed on surface samples. […]
