Best basement waterproofing pros near Westminster, SC

Q: Where should I avoid using a dehumidifier?

• <div><p>One handy thing about whole-house dehumidifiers is, once installed, you don&rsquo;t have to worry about placement or changing the dehumidifier&rsquo;s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.</p></div>

Q: What if there is standing liquid on my concrete?

• <div><p>If there is standing liquid on your concrete, remove it before attempting any of the above cleaning methods. For small amounts of water, use rags, a bucket, and a mop. For larger areas of liquid, lay down cat litter or baking soda to soak up the water first. If you have extremely large pools of water sitting on your concrete, break out the wet vac and get to work.</p></div>

Q: Do all basements eventually flood?

• <div><p>Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn&rsquo;t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a <a href="https://www.angi.com/articles/flood-wall-around-house.htm">flood wall around the house</a> if you live in a flood-prone area.</p></div>

Q: How long does basement waterproofing last?

• <div><p>Typically, waterproofing a basement should last up to 10 years. However, it&rsquo;s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.</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>
