"I used Scope Environmental recently to test floor tile and the underlying mastic to determine if either contained asbestos. I selected Scope because Jeff was very responsive, professional, independent of the abatement companies and his price was competitive. Jeff suggested testing both the tiles and mastic. The tiles tested positive for asbestos but the mastic contained no asbestos. As a result, I saved considerable expense by abating the tiles only and not the mastic so I also used Scope again for the post abatement air testing rather than the abatement company. I would hire Scope again for material and air testing for asbestos, mold or any other potentially toxic materials."

Mold Testing and Remediation FAQs, answered by experts

Inhaling black mold spores, even from behind walls, can cause people to have a wide variety of potential health issues. Some people may only notice a few breathing problems, while others can become quite sick with symptoms related to severe allergies. Constant exposure to mold spores can lead to lung infections and other long-term health problems. If you believe you have black mold inside your walls, you will want to reach out to a pro for an inspection and for advice on how to take care of the problem before it causes severe illness.

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.

Results typically come back within 48 hours, allowing for prompt remedial action.

Black mold often smells musty, stale, or earthy, and some people liken its scent to that of sweaty clothing. While not everyone can identify the smell of mold, you are likely to smell it before you see it, as it usually is hidden in dark, damp areas; instead, the scent may pervade your entire home. If you smell mold, start by opening windows and looking for the source of the smell. If you find mold or are concerned about side effects, call a mold specialist right away, as it can be almost impossible to get rid of yourself.

Mold can damage the surface it’s growing on, cause mold-related sickness, and even affect your upper respiratory system.
