"My review is tiered because the overall service seems to run on tiers. The technician was great. Very personable and professional. 5 stars for his work. Your tests get sent to the lab. The lab explains the results and recommends a company for a DIY solution. This is where things start to fall apart. The company you get referred to has abysmal reviews and the sales pitch feels extremely predatory. That taints my opinion of the lab results which would be teamed up with a business they probably shouldn't recommend. We're planning on either an independent company locally to get a quote from for any remediations we will take or even see what home depot has to offer. In any event please read the reviews of BioCide, the company they will recommend you use. We're still not sure we even have a real problem if they are working together."

"I had a great experience with this company when I needed mold removed from my home. From the initial inspection to the completion of the work, everyone was professional, courteous, and knowledgeable. They explained the process clearly, answered all of my questions, and kept me informed throughout the job. The team arrived on time, worked efficiently, and took the necessary precautions to protect the rest of my home. They did a thorough job removing the affected material and cleaning the area, and they left everything neat and clean when they were finished."

"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

Although fiberglass dust is generally not considered toxic, inhaling excessive amounts of it can lead to health risks. Irritation to the respiratory system, eyes, and skin are common effects of fiberglass particle inhalation. While short-term exposure to the dust may only cause temporary discomfort, long-term or chronic exposure can lead to more severe respiratory problems.

Proper safety measures, such as wearing appropriate protective equipment, including masks and goggles, should be observed when handling or working with fiberglass materials to minimize health risks. It is important to note that, unlike asbestos, fiberglass is not associated with life-threatening illnesses.

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

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Both mildew and mold come from fungi. One of the main differences is that mildew’s texture is dry and powdery, whereas mold is fuzzy and slimy. In addition, mildew isn’t very thick, while mold looks three-dimensional. Also, mildew is typically light in color, whereas mold comes in various shades, including green and black.

If you’ve spotted a skunk or know that one of these furry creatures sprayed one of your family members, your answer is fairly obvious. However, a skunky smell in your house that isn’t coming from these critters may be a sign of a dangerous gas leak. If you suspect this, leave your home immediately and call emergency services. It could also be a build-up of dangerous gas in your home’s septic system or plumbing. Call a professional plumber near you to make an assessment.
