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 water coming up from the floor an emergency?

• <div><p>Yes, water coming up from the floor should be treated as an emergency. If you're unable to either identify or stop the source of the water on your own, contact an emergency plumber right away. In addition to harming your flooring, standing or pooled water can lead to <a href="https://www.angi.com/articles/will-water-damage-concrete.htm">water-damaged concrete</a>.</p></div>

Q: Is a moisture or vapor barrier necessary?

• <div><p>A moisture or vapor barrier helps separate the warm air inside your home from the cold air outside of it. Without it, your walls could collect condensation, mold, or other damage. Check your local building codes to see if including an interior vapor barrier is necessary for your building project or renovation, especially for rooms that are likely to be humid, like bathrooms.</p></div>

Q: Is it worth it to repair a crawl space foundation?

• <div><p>Yes, it&rsquo;s worth it to repair a crawl space foundation, even if the issue seems relatively minor. Foundation problems often get worse and more expensive to fix if you leave them untreated. Additionally, your entire home, from the framing and flooring to the roof system, relies on the foundation for even and level support. Issues with your foundation will almost always manifest as problems in and above your living space, so it&rsquo;s important to find a solution.</p></div>

Q: Can I waterproof my basement myself?

• <div><p>You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn&rsquo;t experiencing a lot of water but is noticeably humid, you can try <a href="https://www.angi.com/articles/how-choose-basement-dehumidifier.htm">running a dehumidifier</a> that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. </p><p>However, if the problem is more severe and requires a more extensive solution, it&rsquo;s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.</p></div>
