Q: How do you make a homemade water barrier?

• <div><p>Sandbags are the most common and efficient way to create a flood barrier at home. Some local authorities pass them around to homes before the risk of a flood. Otherwise, you can use flood-proof house materials, like burlap or woven plastic bags, to make sandbags and fill them with sand or cat litter. Make sure that when you stack them, they&rsquo;re tightly laid on top of each other, creating the effect of a firm wall against accumulating water. </p></div>

Q: What benefits do professionals offer over DIY sealing?

• <div><p>Access to commercial-grade products and equipment, ensuring thorough coverage and long-lasting protection.</p></div>

Q: What are the benefits of foundation drainage?

• <div><p>Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home&rsquo;s structural integrity.</p></div>

Q: What is the safest insulation for basement walls?

• <div><p>Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don&rsquo;t have to worry as much about a fire breaking out as you would with spray foam insulation. </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>
