Q: How can I prevent mold after water damage?

• <div><p>Mold and other fungi love moisture, so the best way to prevent <a href="https://www.angi.com/articles/6-steps-prevent-carpet-mold-after-water-damage.htm">mold growth after water damage</a> is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.</p></div>

Q: Can underfloor insulation cause moisture and mold?

• <div><p>Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and&mdash;if your floors are wood&mdash;rotting.</p></div>

Q: Can you finish a basement that leaks?

• <div><p>Yes, you can finish a basement that leaks, as long as you address the leak first. Before finishing a basement, you&rsquo;ll need to repair any cracks in the walls and waterproof the basement to prevent future leaks. It&rsquo;s much harder to clean up a water leak from a finished basement than an unfinished one, so preemptively addressing any leaking areas prevents expensive repairs in the future.</p></div>

Q: Can a damp basement affect upstairs?

• <div><p>Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement. </p></div>

Q: Why does my crawl space smell like a sewer?

• <div><p>A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor. </p></div>

Jeremiah made the trek up to the upper peninsula of Michigan to paint and clean up our exterior chimney. He did a magnificent job, and the only issue now is the rest of my house exterior looks subpar next to it. Nice person and reasonable prices to boot. A++
