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. When there is mold growth inside a building, it is an indication of a water problem, which could mean that there is excessive water leaking somewhere in the building of which when it produces a damp condition can richly invite for mold growth. 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.
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.
Mold inspection observes these five steps: interview of occupants or building maintenance caretaker, visual inspection, sampling, sampling analysis, 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 third important task of the mold inspector is to take air samples, outside and inside the building, by using a special sample instrument that can collect mold spores and provide counting results of spores collected, thereby giving a good analysis if the air quality inside the building has deteriorated.
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 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.
