Q: How do I prevent foundation cracks?

• <div><p>The first step to preventing foundation cracks is to repair any current ones. When one crack forms, it becomes more likely that a second crack will follow. A few other tips include performing regular foundation checks, cleaning spouts and gutters, and installing exterior drains if needed. For those living in a hot and arid area, you should water your foundation every other day.</p></div>

Q: Is water coming up from the floor an emergency?

• <div><p>Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to <a href="https://www.angi.com/articles/will-water-damage-concrete.htm">water-damaged concrete</a>.</p></div>

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>
