Can a slab foundation sink?

• <div><p>Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including <a href="https://www.angi.com/articles/slab-on-grade-foundation.htm">slab-on-grade foundations</a> and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.</p></div>

Q: How do you tell the difference between settling and foundation problems?

• <div><p>Most of the time, normal foundation settling will present as thin cracks in the foundation and minor creaks in the floorboards. In contrast, you can identify foundation issues by wide or uneven foundation cracks, horizontal or step-shaped gaps on the foundation wall, or cracks that go around corners of your foundation. Foundation problems can also cause changes in your living area, like increased humidity, uneven or sloping floors, nail pops in drywall, countertops pulling away from the wall, and windows and doors getting stuck. When in doubt, call in a professional to identify the underlying cause.</p></div>

Q: What is the best way to fix cracks in the basement floor?

• <div><p>The best solution to <a href="https://www.angi.com/articles/how-to-fix-foundation-cracks.htm">fix a foundation crack</a> in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.</p></div>

Q: Does insurance cover foundation cracks?

• <div><p>Homeowner&rsquo;s insurance doesn&rsquo;t cover foundation cracks unless they&rsquo;re a result of a natural disaster like an earthquake, vandalism, or a vehicle accident that causes sudden damage. Taking care of your foundation to prevent problems with expansive soil and drainage is considered ongoing maintenance, and your insurance company expects the homeowner to carry out that preventative maintenance.</p></div>

Q: What is the best foundation repair method?

• <div><p>The best foundation repair method will depend on the issue you&rsquo;re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it&rsquo;s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.</p></div>

"Edgar’s communications via email, phone and text were great - he always responded quickly. And he always showed up on the day he said he would work. He and his team worked very hard day to day and also had very good manners. This was a big job - garage floor, corner lot with lots of sidewalks (personal walkways too) and spruced up front steps. My husband and I both agreed on 4 stars (which on this scale reads as good and 5 stars read as great but to me 4 stars = great and 5 = excellent). We agree that after Edgar has some more experience running his company that every new job he undertakes will add to that experience and small mistakes will be a thing of the past. "
