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: Should you put plastic over insulation in basement walls?

• <div><p>A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.</p></div>

Q: What is crawl space encapsulation and what are the negatives?

• <div><p>The only real negative when encapsulating a crawl space is that the cost is high. It can cost several thousands of dollars to do this project. However, it protects your house and those in it by providing an energy-efficient space instead of one that frequently pools moisture and causes damage through <a href="https://www.angi.com/articles/black-mold-lurking-your-house.htm">mold growth in your home</a>. While less common, another disadvantage could be encapsulation making access to pipes and electrical slightly more complicated in certain crawl spaces.</p></div>

Q: How long does it take to waterproof a basement or crawlspace?

• <div><p>The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.</p></div>
