The air quality inside a residential or commercial building may be greatly affected when there is a detected mold environment growing inside, especially when the molds are of the airborne species, as they are a common source of allergen and can be the primary cause of health problems for the building residents, such as sneezing, runny nose, cough, eye irritation, upper respiratory irritation, and, in serious condition, 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. Another adverse effect of mold presence inside a building establishment is that they can cause structural damage by decomposing wood and porous materials, drywalls, and even carpeting.
As part of a maintenance procedure in a building structure, mold inspection should be regularly performed, to meet up on the following objectives: test for mold growth in the establishment; locate the mold population when there is a positive test result of their existence; identify their specie; and conduct a post-inspection after a remedial action has been performed to eliminate the mold presence.
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.
A mold inspector will usually conduct first an interview to get as much information needed for him to conduct his next step of inspection and the information that he will most likely ask are about the humidity condition inside the building, whether there has been a leaking problem existing in the roof or plumbing fixtures, have the occupants smell some kind of moldy odor, or has there been a detected mold population growth inside the structure.
As soon as the mold inspector completes his interview with the homeowner or building caretaker and quickly studying the information he has gathered in the interview, he proceeds to the next step which is conducting an ocular inspection to pinpointed areas where there are likely presences of mold growth, using various tools to confirm the presence, such as a hydrometer to check on the humidity of the room, moisture meter to determine the presence of moisture, borescope to view wall sections, laser thermometer to evaluate the actual heat composition of the surface, and digital camera to record graphically the mold growth presence.
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.
The mold inspector brings the air samples taken in the building to a professional analyst to determine the population of mold spores for every cubic meter of air sample and to also determine the kind of mold specie found in the building.
The summary report of the mold inspector constitutes the visual proof of mold presence, spore level in the air in the building, mold specie present, conclusions and recommendations in maintaining the building condition, as well as measures to remove the presence of molds.
