Q: Should I avoid buying a house with a crawl space?

• <div><p>Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn&rsquo;t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn&rsquo;t have any more issues than a slab or basement home.</p></div>

Q: How do I get rid of moisture under my elevated deck?

• <div><p>If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.</p></div>

Q: When should you not use a dehumidifier?

• <div><p>Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze. </p></div>

Q: What are the hardest parts of finishing a basement?

• <div><p>Roughing in and connecting utilities are the hardest parts of finishing a basement, and they&rsquo;re the parts we typically don&rsquo;t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.</p></div>

Basement Waterproofing questions, answered by experts

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit.
