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. 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.
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.
Mold inspection observes these five steps: interview of occupants or building maintenance caretaker, visual inspection, sampling, sampling analysis, 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.
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.
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 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.
