You will also want to use fans in the crawl space to help circulate the air and increase the ventilation. If the crawl space has suffered any flood damage, you will also want to set up dehumidifiers in order to remove any additional moisture in the air.
Additionally, you may want to look into installing waterproofing materials, such as a vapor barrier, to help keep moisture out of the crawl space in the future.
What humidity should my crawl space dehumidifier be set at?
The humidity setting for your crawl space dehumidifier should ideally be set to 50-60% relative humidity. This is the range that is most comfortable for human beings and will maintain the best environment to prevent mold and mildew growth.
Additionally, this range will also protect items stored in the crawl space, such as clothes and wood, from warping, discoloration, and other damages that can be caused by high levels of moisture. Although it may be tempting to turn the setting as low as possible, doing so could cause the dehumidifier to run continuously, resulting in equally damaging low humidity levels and higher-than-necessary energy costs.
Additionally, it may be necessary to raise the humidity settings slightly during the winter months, as cold air holds small amounts of moisture for longer.
How long should dehumidifier sit before using?
It is recommended to allow a dehumidifier to sit for at least 24 hours before turning it on for the first time. This will allow time for any packaging residue or debris to settle before the unit is turned on and begins to circulate the air.
After 24 hours, the dehumidifier can be plugged in and turned on. It is important to note that it is good practice to allow the unit to operate for several hours before adjusting the settings and to let the humidifier cycle through several on and off cycles before changing the settings.
This will allow you to get a feel for how the unit works before adjusting the settings and ensure that the unit is functioning properly.
Will a dehumidifier prevent mold in crawl space?
A dehumidifier can help to prevent mold growth in crawl spaces or other damp areas of the home by reducing humidity levels. The ideal humidity level for a home is between 30-50 percent, for a crawl space it should not exceed 55 percent.
Setting up a dehumidifier to regulate the humidity within this range can help to prevent the growth of mold in a crawl space. In addition to the dehumidifier, you should make sure that the crawl space is sealed from outside water sources and the walls are insulated.
It’s also beneficial to point two separate dehumidifiers in the crawl space, one facing blowing air in and the other facing blowing out, for optimal moisture control. These preventive measures can help to limit the amount of moisture in the crawl space, eliminating the environment necessary for mold to grow.
Should a crawl space be completely dry?
A crawl space should generally aim to be as dry as possible. Ground moisture and humidity can cause a number of issues, such as wood rot and mold, so it’s important that the area be well-ventilated and kept dry.
A few methods to prevent moisture buildup include making sure there is sufficient ventilation, using a sump pump to keep water out, installing a ground moisture barrier, and sealing air ducts and openings.
Checking for water leakage and repairing any plumbing or roof problems as soon as possible is also important to avoid mold and other moisture issues.
Should the dirt in my crawl space be wet?
No, it is not advisable for the dirt in your crawl space to be wet. Moisture in the crawl space can create a number of issues, including the growth of mold and mildew, wood rot, and structural damage.
