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: What causes a basement wall to bow?

• <div><p>External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure&mdash;these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent. </p></div>

Q: What protects you from mold?

• <div><p>When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.</p></div>

Q: Should you have vents in a crawl space?

• <div><p>Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. </p></div>
