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.
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.
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 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.
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.
