Q: Why does my basement leak after heavy rain?

• <div><p>If your basement often leaks after heavy rain, it&rsquo;s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home&rsquo;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's the difference between a vapor barrier and insulation?

• <div><p>A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air&mdash;and sometimes moisture&mdash;that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won&rsquo;t get damaged from moisture, like rigid foam board or expanding spray foam insulation.</p></div>

Q: How long does a vapor barrier last?

• <div><p>A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It&rsquo;s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.</p></div>

Q: Do services include waterproofing or UV protection?

• <div><p>Yes, many repair services include reapplying waterproofing and UV-resistant coatings.</p></div>

Q: Does water damage always result in mold?

• <div><p>Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly&mdash;ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.</p></div>
