Q: How expensive is moisture barrier padding?

• <div><p>Generally, moisture barrier padding costs <b>$0.75 to $1.50</b> per square foot, varying by brand and mix. That&rsquo;s a lot more than standard padding, which runs <b>$0.25 to $0.90</b> per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.</p></div>

Q: What preventative measures can reduce the risk of future water or storm damage?

• <div><p>Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.</p></div>

Q: Should I pick a topical or a penetrating sealer for my project?

• <div><p>Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.</p></div>

Q: What happens if a crawl space is not vented?

• <div><p>If a crawl space isn&rsquo;t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards. </p></div>
