Molds have an important role in the natural environment, but when they grow and exist inside building establishments, they create a negative effect on the air quality inside the building atmosphere, especially with airborne type of mold species, being a source of allergen and can adversely affect the health of the dwellers, who may have allergic reactions to molds, thus, causing them to experience nasal problems, like sneezing or runny nose, and other health reactions, such as coughing, eye irritation or upper respiratory irritation and even as severe as an asthma attack. Most common molds thrive when there is conducive moisture present in their environment; therefore, when molds are found inside a building, this is a positive indication that there is a water leak somewhere inside that has not been found and remedied and, thus, one can feel some kind of dampness condition, as well as, a mold smell indicating its presence and growth inside the building. The natural function of molds is to decompose organic matter, especially matters that are no longer living; therefore, when they are found growing inside a building establishment, their natural function takes an adverse effect on decomposing materials inside the building, such as wood, porous objects, drywalls, and carpets.
The purposes of conducting a mold inspection are the following: testing for the presence of molds inside an establishment; when there is a positive presence, identifying the mold species; locating where the molds are growing inside the establishment; and, when remedial action has been done to remove the molds, a post-inspection is performed to assess if the molds have been completely eliminated.
Conducting a mold inspection follows these 5 important procedures: interviewing of building owner or caretaker; conducting an ocular inspection; taking samples; having the samples analysed; and reporting.
Most of the relevant questions asked by a mold inspector during an interview with the building owner or caretaker are on the following: humidity problems inside the building, mold odor, presence of rook leaks or plumbing leaks, or any visible mold found inside.
As soon as all needed information have been collected and studied, the mold inspector conducts an ocular inspection of the suspected areas where mold presence is existing and specific tools will be helpful during his inspections, such as a borescope to view some wall sections, laser thermometer to check on the surface temperature, moisture meter to find out the moisture presence of the room, hydrometer to determine the amount of humidity in the room, as well as a camera to take shots of a detected mold growth.
The mold inspector proceeds with the third step of taking air samples, outside and inside the building, using a special air collector device that has the design of specifically collecting airborne mold spores and which can, at the same time, provide conclusive results of the spore counts, giving the inspector an idea if the air quality inside the building is of health risk or not.
Once air samples have been collected they are then taken to a professional analyst for determination and analysis for the number of mold spores per cubic meter of air, as well as finding out the specific type of mold found.
The final step is the written report of the inspector presenting photos of the mold growth, spore level and type and his conclusions and recommendations for the removal of the molds.
