Q: Can underfloor insulation cause moisture and mold?

• <div><p>Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and&mdash;if your floors are wood&mdash;rotting.</p></div>

Q: Can I waterproof my basement myself?

• <div><p>You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn&rsquo;t experiencing a lot of water but is noticeably humid, you can try <a href="https://www.angi.com/articles/how-choose-basement-dehumidifier.htm">running a dehumidifier</a> that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. </p><p>However, if the problem is more severe and requires a more extensive solution, it&rsquo;s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.</p></div>

Q: Is a vapor barrier required in a crawl space?

• <div><p>In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to <a href="https://www.angi.com/articles/4-steps-protect-your-crawl-space.htm">keep your crawl space dry</a>.</p></div>

Q: How can I prevent ductwork from sweating in a crawl space?

• <div><p>Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.</p></div>

Q: Who should I hire for crawl space repair?

• <div><p>You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don&rsquo;t have ongoing damage. They&rsquo;ll also often take preventative measures to stop the issue from recurring in the future.</p></div>
