Q: Does a basement need ventilation to reduce humidity?

• <div><p>Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.</p></div>

Q: What soaks up moisture under a house?

• <div><p>A sump pump can remove excess moisture from under a house if standing water is present. Other ways to <a href="https://www.angi.com/articles/4-steps-protect-your-crawl-space.htm">protect your crawl space from moisture</a> include installing a vapor barrier, using a dehumidifier, installing insulation, and using a fan to dry the space. Finally, keeping your gutters clear of debris and positioning your downspouts away from the home&rsquo;s foundation can prevent moisture from getting into the crawl space in the first place.</p></div>

Q: What can I use instead of crawl space encapsulation?

• <div><p>Venting the crawl space can be a good alternative to encapsulation if you live in a dry climate and the moisture problem isn&rsquo;t severe. You could also try a dehumidifier or install a vapor barrier on the floor, leaving the walls exposed. A new drainage system may eliminate the moisture problem if it is not caused by humidity.</p></div>

Q: Is it okay for a crawl space to be wet?

• <div><p>No, you don&rsquo;t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know <a href="https://www.angi.com/articles/how-to-waterproof-your-basement.htm">how to waterproof your basement</a> to prevent ongoing problems. </p></div>
