Is it better to have a vented or sealed crawl space?

• <div><p>It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible. </p></div>

Why does my basement leak after heavy rain?

• <div><p>If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.</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>

Over time, hydrostatic pressure can cause structural damage to your home.</p></div>

Q: Can water seep through cracks in the basement floor?

• <div><p>Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don&rsquo;t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.</p></div>

Q: How deep should a crawl space be under a house?

• <div><p>A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.</p></div>
