Q: How long does a vapor barrier last?

• <div><p>A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It&rsquo;s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.</p></div>

Q: How is damp proofing different from waterproofing?

• <div><p>Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it&rsquo;s more protective, waterproofing typically costs more than damp proofing. </p></div>

Q: Does homeowners insurance cover basement flooding or water damage?

• <div><p>Standard homeowners insurance policies may cover basement water damage or flooding, but only if it is caused by a sudden and accidental event that is a covered peril, such as a burst pipe or a failing appliance. Damage caused by natural flooding from extreme weather, groundwater seepage, or heavy rain is typically excluded and requires a separate flood insurance policy. Some insurers also offer an optional water backup endorsement for issues like sewer backups. Review your policy or speak with your agent to understand your specific coverage.</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>

Q: How expensive is moisture barrier padding?

• <div><p>Generally, moisture barrier padding costs <b>$0.75 to $1.50</b> per square foot, varying by brand and mix. That&rsquo;s a lot more than standard padding, which runs <b>$0.25 to $0.90</b> per square foot. The price difference between these two options might seem steep, but think of it as insurance against future carpet replacement costs and subfloor damage. If you have pets or kids, that extra investment in high-risk areas like your living room often pays off.</p></div>
