We at H&L Environmental Services recognize that many misconceptions with respect to mould growth still persists and as such, we delve deeper into how moisture results in mould growth and proliferation.
Apart from indoor sources of moisture: high relative humidity, plumbing leaks, water intrusion and condensation, climate change has also resulted in an increased prevalence of mould issues in the indoor environment.
Climate change causes increased prevalence of moisture events; storms and hurricanes. These climatic events result in floods and forceful water intrusion which can persist for an extended period of time, wetting building structures and materials.
It is very difficult to dry these structures before the recommended 24-48 hours’ period. The moisture then causes growth of mould and other biological contaminants indoors. If it is not corrected, this mould can make building occupants sick.
Moisture Control is the Key to Mould Control therefore the United States Environmental Protection Agency has provided a few guidelines to follow:
When water leaks or spills occur indoors - act quickly. If wet or damp materials or areas are dried 24-48 hours after a leak or spill happens, in most cases mould will not grow.
Clean and repair roof gutters regularly.
Make sure the ground slopes away from the building foundation, so that water does not enter or collect around the foundation.
Keep air conditioning drip pans clean and the drain lines unobstructed and flowing properly.
Keep indoor humidity low. If possible, keep indoor humidity below 60 percent.
If you see condensation or moisture collecting on windows, walls or pipes act quickly to dry the wet surface and reduce the moisture/water source. Condensation can be a sign of high humidity.
