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. Molds exist to contribute to the natural habitat of decomposing dead matters, that is why they can pose a serious adverse effect inside a building environment, when they are found existing, as they are likely to decompose any wood, porous materials in the building, including 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.
Common issues inquired through the interview by the mold inspector are on these topics: humidity inside the building, mold smell, any possible roof or plumbing leaks, or detected mold presence inside the building.
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.
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.
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.
