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. Water leaking constantly in a building and has not been given immediate remedial action for a long period of time may result into dampness in the indoor environment and the existence of 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.
Mold inspection is a necessary building maintenance procedure to evaluate on the following objectives: check if the building has the presence of molds; identify the kind of mold species inside a building establishment; locate where the mold population is growing; test for the indoor air quality by scientifically measuring the amount of mold spores present in the air; and post-check if molds have been completely removed inside a building.
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.
When the inspector receives a positive reporting from the owner or caretaker of mold presence, he performs a visual inspection into the spot areas where there is likely water penetration or evidence of a mold habitat existing, using tools like moisture meters for detecting moisture, hydrometers for measuring the humidity, borescopes for viewing sections of walls, or laser thermometers for checking on the surface temperatures, as well as digital photographs, if the mold presence is detected.
Most important in the course of the inspection is taking air samples, outdoor and indoor, using a special sampling device that can collect mold spores of which the amount of spores collected will determine if air quality inside the building has been greatly affected.
A special laboratory analyst handles the given air samples by determining the number of mold spores present per cubic meter of air and, at the same time, analysing 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.
