Q: Should you have vents in a crawl space?

• <div><p>Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. </p></div>

Q: How do you know if you have a leak under your foundation?

• <div><p>A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it&rsquo;s a plumbing line embedded in your slab, you&rsquo;ll also likely notice above-average water bills.</p></div>

Q: How long does it take for water to cause structural damage?

• <div><p>Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they&rsquo;ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.</p></div>

Q: Why does my crawl space smell like a sewer?

• <div><p>A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor. </p></div>

Q: What is the best drainage around a foundation?

• <div><p>Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it&rsquo;s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques&mdash;like soil gradation and gutter and leader installation&mdash;to resolve the underlying problem.</p></div>
