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: Where should I avoid using a dehumidifier?

• <div><p>One handy thing about whole-house dehumidifiers is, once installed, you don&rsquo;t have to worry about placement or changing the dehumidifier&rsquo;s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.</p></div>

Q: Can you get sick from a wet basement?

• <div><p>While water in your basement is unlikely to make you sick unless it&rsquo;s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the <a href="https://www.cdc.gov/mold-health/about/index.html">Centers for Disease Control and Prevention (CDC)</a>, inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.</p></div>

Q: Is sealing a foundation ever not recommended?

• <div><p>In some circumstances, <a href="https://www.angi.com/articles/foundation-refacing.htm">foundation refacing</a> or repair may be a better option for your home than sealing a foundation. It&rsquo;s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it&rsquo;s a good idea to get a professional opinion so you can avoid bigger problems down the road. </p></div>

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>
