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>

Q: Can water leak through window frames?

• <div><p>Water leakage through window openings is much more common in older homes, but it can also create issues with window frames that are improperly installed. If left unattended, water buildup can cause damage to surrounding fixtures, lead to harmful mold, and compromise the architectural integrity of your home. The potential damage that a water leak poses makes investing in weather- and water-proofing your window frames entirely worthwhile. </p></div>

Q: Is it okay if it rains on underlayment?

• <div><p>As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it&rsquo;s okay if it gets wet. However, you shouldn&rsquo;t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you&rsquo;ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.</p></div>

Q: What are signs that I need to waterproof my basement?

• <div><p>Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:</p><ul><li><p>Water in your basement, including damp walls or puddles on the floor</p></li><li><p>Mold spots in your basement</p></li><li><p>Musty smells or odors</p></li><li><p>Warped doors or walls</p></li><li><p>Cracks in walls</p></li><li><p>Insect issues, such as cockroaches and termites</p></li></ul><p></p></div>

Q: What causes problems with crawl space foundations?

• <div><p>Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.</p></div>

You don’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’s ideal for homes in humid areas.

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.

Cracks in walls
Insect issues, such as cockroaches and termites
