Q: How long does it take for mold to grow on drywall?

• <div><p>Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. </p><p>While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.</p><p> </p></div>

Q: What is the black stuff around my air vents?

• <div><p>Seeing black dots around the air vents is alarming, but don&rsquo;t worry. It&rsquo;s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months. </p></div>

Q: Can I remove mold myself?

• <div><p>It&rsquo;s possible to scrub mold off of visible surfaces yourself, but it&rsquo;s not usually a good idea. Mold is not only a potential health risk, but it&rsquo;s also difficult to treat in its entirety, especially because it can grow behind walls and in other hidden areas a DIYer might miss. Since mold is a serious and often pervasive issue, you should hire a professional that will remove all of the mold&mdash;including any that might be hidden&mdash;run industrial air scrubbers to remove airborne particles, and complete mold testing to ensure the underlying problem is solved.</p></div>

Q: How do professionals ensure safe collection and removal?

• <div><p>Professionals use appropriate equipment to prevent property damage and ensure efficiency.</p></div>

Q: Does mold go away with a dehumidifier?

• <div><p>No, a dehumidifier does not actually remove mold. It only reduces the moisture in the room, which mold needs in order to grow. If you already have mold, you&rsquo;ll need to do a deeper cleaning or call a pro to remove the existing mold first.</p></div>
