What is the best ventilation for a crawl space?

• <div><p>The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system.

Q: How do you seal a leaky concrete slab?

• <div><p>You can <a href="https://www.angi.com/articles/how-to-seal-concrete.htm">seal a concrete slab</a> by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.</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: Are slab leaks common?
