Q: Is it safe to stay in a house with a flooded basement?

• <div><p>It depends on <a href="https://www.angi.com/articles/causes-and-costs-flooded-basement.htm">what caused your basement flooding</a>, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don&rsquo;t have electrical lines down there, but make sure you call in professionals to fix the issue immediately. </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: Is it unhealthy or dangerous to live in a damp basement?

• <div><p>Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.</p></div>

Q: How hard is it to add a basement to an existing house?
