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: Should you cover the dirt in a crawl space?

• <div><p>Covering the dirt floor in your crawl space with a vapor barrier helps insulate the space and improve the air quality in your home. It protects your crawl space from pest infestations, excess moisture, and mold growth. It also makes the crawl space less dusty, which means there&rsquo;s a lower chance of dust mites breeding and causing allergic reactions in your home.</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: Is a vapor barrier required in a crawl space?

• <div><p>In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to <a href="https://www.angi.com/articles/4-steps-protect-your-crawl-space.htm">keep your crawl space dry</a>.</p></div>

Q: How can I prevent ductwork from sweating in a crawl space?

• <div><p>Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.</p></div>

"Their technician did an excellent inspection job: he crawled under the house, took photos, and did a very precise measurement of the house level. However, Saber doesn't replace steel girders under what are called "Princess homes". They can do jack replacement and leveling, but first I need a rusted steel girder replaced, for which I must hire a different foundation contractor."
