How much does basement waterproofing cost?

• <div><p>The <a href="https://www.angi.com/articles/how-much-does-basement-waterproofing-cost.htm">cost of basement waterproofing</a> is <b>$4,950</b> for the average homeowner. However, you could end up paying between <b>$600 and $14,000</b>, depending on factors like basement size, waterproofing method, and the region you live in. </p><p>If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between <b>$2,500</b> <b>and $5,000</b> to waterproof, but that price rises significantly for a larger basement. </p></div>

How do I remove standing water around the foundation?

• <div><p>French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.</p></div>

Q: Why are houses built with crawl spaces?

• <div><p>The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They&rsquo;re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they&rsquo;re at less of a risk of freezing.</p></div>

Q: What happens if water gets under pavers?

• <div><p>Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the <a href="https://www.angi.com/articles/how-much-does-it-cost-install-patio.htm">cost to build and install a patio</a> to replace the damaged one. </p></div>

Q: How long does ice and water shield last?

• <div><p>In perfect conditions&mdash;meaning, no overexposure to the elements without roofing material on top of it&mdash;an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.</p></div>
