Best basement waterproofing pros near Westminster, SC

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: 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: Do crawl spaces attract bugs?

• <div><p>Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier&mdash;called <a href="https://www.angi.com/articles/seal-wet-crawl-space-encapsulation.htm">crawl space encapsulation</a>&mdash;on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.</p></div>

Q: Should I pick a topical or a penetrating sealer for my project?

• <div><p>Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.</p></div>

Q: Do I need a dehumidifier in my encapsulated crawl space?

• <div><p>You don&rsquo;t always need to install a dehumidifier in your encapsulated crawl space, but it might be a good idea in certain instances. If you notice obvious signs of condensation, mold, or musty smells permeating from your crawl space, a dehumidifier can help. It&rsquo;s ideal for homes in humid areas.</p><p>In a worst case scenario, structural damage like rust on metal beams, rotting wood, and swelling on doors and windows can signal moisture problems that would benefit from a dehumidifier.</p></div>
