Q: What are the most cost-effective foundation repairs?

• <div><p>The most cost-effective foundation repair is using <b>masonry patches and sealants</b> to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they&rsquo;re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost <b>$500</b>, but a sealant like an epoxy crack injection can total <b>over $2,000</b>. If you&rsquo;re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.</p></div>

Q: Should I avoid buying a house with a crawl space?

• <div><p>Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn&rsquo;t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn&rsquo;t have any more issues than a slab or basement home.</p></div>

Q: Can underfloor insulation cause moisture and mold?

• <div><p>Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and&mdash;if your floors are wood&mdash;rotting.</p></div>

Q: What materials can stop a flood?

• <div><p>The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged. </p></div>

Ralph replaced my large, badly cracked, uneven patio to perfection. He is willing to tackle any concrete problem, always has a solution and produces amazing results. Lots of people lay concrete and may even do it cheaper, but no one does it better than Ralph Schmidt Concrete Construction!
