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.
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.
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.
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.
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 last segment in the mold inspection is a documented summary report which consists of the following: photos of the mold presence and its specific locations, population level of mold spores in the air inside the building, the specific mold found, the inspector’s conclusions and strong recommendations in stepping up measures to prevent mold growth, as well as its elimination.
