Biohazard Remediation questions, answered by experts

Rust in your bathtub occurs when iron in the water or on metal components in your tub are exposed to oxygen, but while it’s unsightly, it won’t make bathing dangerous. However, if the rust appears under or around your tub spout or shower head, it could indicate that you have high levels of iron in your water. Drinking water with small amounts of iron in it usually doesn’t pose a health risk, but you might want to consider installing a water softener. The presence of iron could indicate that you have hard water, which can create some plumbing issues.

Neglecting to clean your chimney can lead to serious safety hazards. A primary risk is the buildup of creosote, a highly flammable substance that can ignite and cause a dangerous chimney fire. This buildup can also create blockages in the flue, resulting in poor venting of smoke, soot, and toxic gases like carbon monoxide, which can then enter your home and create dangerously poor indoor air quality. Additionally, creosote is acidic and can damage the chimney's mortar and metal components over time, potentially allowing smoke to leak into your house. To prevent these issues, it is essential to schedule an annual chimney cleaning with a professional.

The necessary frequency of mold cleaning in your home will depend on several factors, including the climate, the presence of moisture sources, and the type of siding. It's generally recommended to inspect your siding regularly and clean any mold growth as soon as it appears to prevent it from spreading or causing damage. If you’re not sure how often you should clean mold off siding, you can always contact a siding contractor near you to consult on what maintenance schedule will work best for your home. 

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.
