When the relative humidity of your crawl space is 70% or higher, mold can thrive. "Relative" humidity is the humidity level expressed in a percentage of the amount of moisture in the air needed for "saturation" (i.e. the highest level of humidity – 100%). The amount of water the air can hold (humidity level) is dependent upon the temperature of the air itself. When the humidity level begins to creep up past 70% relative humidity, this provides the perfect environment for mold growth!
Condensation is an indication that the air within your crawl space has reached 100%. The air can no longer hold the moisture and it's condensing onto the surfaces, causing the organic materials that make up your crawl space to become damp, which will result in mold growth.
A hygrometer is a device used to measure the humidity of indoor air. Using this tool to measure the humidity of your crawl space is a great way to monitor the amount of moisture present. A thermo-hygrometer measures both temperature and humidity level. These devices are even more ideal for crawl space atmosphere monitoring because the relative humidity level is contingent upon the moisture in the air in relation to the air's temperature.
Being able to track the changes in both of these conditions in your crawl space will allow you to see trends and anticipate necessary changes. For instance, if the weather is hot during the day but the temperature plummets at night, this can cause problems for your crawl space's humidity levels. The daytime temperature is higher, which allows the air to hold more moisture. As night approaches and the air cools, the amount of moisture the air can hold also decreases – causing the relative humidity level to rise. A crawl space that was at a permissible humidity level during the day can run into problems when night falls. Being able to see these changes on your thermo-hygrometer can help you identify these types of trends so that you can respond appropriately. Keep in mind that properly insulating your crawl space and installing vapor barriers will help regulate the temperature and keep moisture levels down, resulting in less fluctuations in the air’s relative humidity.
Having unconditioned air below your living spaces makes the whole house harder to heat and cool as well as provide the perfect damp setting for mold spores to breed.
In the past, we were told that crawl spaces needed to be ventilated. Now, however, we are learning that crawl spaces need to be treated almost as if they were living spaces. In other words, areas that are in contact with your living space affect your living space. So if you have a crawl space, what solution is available?
Midwest Enviro Solutions can help you dry out the dampest crawl spaces and turn them into drier, healthier foundations for your home that aren't breeding grounds for mold spores.
Turning crawl spaces into dry spaces!
Our Dry-space technique combines the following:
- A thorough cleaning of the space, including mold remediation
- Installation of a wall-to-wall guide, durable vapor barrier.
- Attachment of the vapor barrier over ground and up sidewalls to 6 inches below floor joists.
The result is an energy efficient, healthy home. Midwest Enviro Solutions dry space methods described above not only helps mold-proof your home, but the combination of these methods will make it more energy efficient and comfortable.
