Q: Does a crack in the basement floor mean foundation problems?

• <div><p>Not all cracks in the basement floor signal foundation problems. As the house settles, you&rsquo;ll notice very thin hairline cracks, which you don&rsquo;t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have <a href="https://www.angi.com/articles/are-cracks-my-basement-floor-problem.htm">cracks in your basement floor with heaving</a>, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.</p></div>

Q: Are horizontal cracks structural?

• <div><p>Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage. </p></div>

Q: Does homeowners insurance cover the cost of slab leaks?

• <div><p>Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.</p></div>

Q: What happens if you don’t fix foundation problems?

• <div><p>If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:</p><ul><li><p><b>Structural Damage:</b> Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.</p></li><li><p><b>Water Damage and Pests:</b> Moisture and water intrusion can cause flooding, mold growth, and pest infestations.</p></li><li><p><b>Health and Safety Risks:</b> Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.</p></li><li><p><b>Reduced Home Efficiency:</b> A compromised foundation can negatively impact your home's energy efficiency.</p></li></ul><p>To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.</p></div>

Q: What happens if I overwater my foundation?

• <div><p>Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.</p></div>

"The work was fine, at least so far! We hired them to repair cracks in the foundation, and the estimator thought that there were three cracks. When the person showed up to do the work, he only found (and repaired) two cracks. It took several months for them to adjust their bill, which is my only complaint. It took several phone calls and emails, and they didn't reduce the bill very much."

"Andrew did a great job digging footings and keys for a major wall/foundation. He even dug deeper on one area due to the previous excavator taking shortcuts and if he had not the whole house would have been built on poor ground and had foundation issues later! Very knowledgeable and communicative throughout. The price was also very fair and he did exactly what we discussed plus a little extra. I would highly recommend him!"
