"The guy was really helpful but I couldn't afford what he charged me at that time. Otherwise I thought that they are a pretty good company. The guy who came out was really informative and helpful. As a matter of fact we had sewer damage and he had suggested about to claim with the metropolitan sewer industry. He was really pretty knowledgeable and very professional. The estimate was for around $4500 to $5000. It would have been well worth it but I couldn't afford it at that time. I think he was excellent personally. He was here when he said he would be here."

"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

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

When used in the correct quantity and with the right procedures, boric acid will produce fumes with limited to no toxicity. You’re more likely to experience adverse side effects from boric acid toxicity by accidentally ingesting it or touching it with bare skin. All the same, wearing an air-filtering mask is a good way to keep even minorly toxic fumes out of your system. Don’t forget gloves, too!

Mildew starts as a tiny spot, but if left untreated, it can severely damage your home as well as cause life-threatening health issues. Mildew eats away materials like wood and drywall and if left untreated can destroy entire walls and buildings. Mold sickness is almost a guarantee if you don’t tackle this problem as soon as it rears its head.

Dog vomit slime mold is not toxic to humans, plants or pets. However, it can act as an allergen to people with allergies. Dog vomit slime mold is considered more of a cosmetic nuisance. However, it is beneficial to its ecosystem as it helps break down organic matter, releasing nutrients for plants.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.
