"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

Thorough inspection, air quality tests, and surface sampling to detect mold presence and levels.

If you're wondering about black stains on brick at your home, the answer is that you're not looking at efflorescence. While efflorescence can be darker when certain types of salt are involved, black staining is caused by carbon staining, pollution from vehicles, and chimney soot. Black stains can also be caused by organic materials like lichen, algae, or mold.

Yes, mold behind drywall can affect your health, even if it is not visible. Mold releases spores and mycotoxins into the air that can be inhaled, leading to various health issues including respiratory problems, allergies, asthma symptoms, coughs, and other infections. While individuals with pre-existing conditions like allergies, asthma, or weakened immune systems are particularly vulnerable, anyone can be affected by prolonged exposure. Additionally, if left untreated, mold can spread throughout your home and compromise its structural integrity, resulting in costly repairs.

Neglecting mold growth on wood can result in various issues that deteriorate its appearance and jeopardize its structural stability. The mold's ability to multiply and expand can disintegrate the fibers of the wood, weakening it further. In addition, the allergenic spores and mycotoxins released by mold can pose health hazards through inhalation or contact. Ignoring the mold's presence allows it to thrive, increasing the likelihood of spreading to other surfaces and requiring extensive and expensive measures to control in the future. Addressing mold on wood promptly is crucial to preserving its condition and safeguarding the health of those around it.

The cost for mold remediation typically ranges from $1,125 to $3,350, with a national average of around $2,400. The final price depends on various factors, including the location and square footage of the affected area, the type of mold, and local labor costs.

Additional factors that influence the total cost include:

  • Extent of Damage: The overall price can increase significantly if extensive repairs are needed after mold removal, such as replacing large sections of drywall. Removing mold from a small area of drywall might cost between $300 and $825, but full wall replacement is more expensive.

  • Health Risks: The cost is also justified by the health risks associated with toxic mold, which can cause respiratory distress, act as carcinogens, or even damage the nervous system.

  • Comprehensive Service: Remediation involves not only removing the mold but also addressing the moisture issues that caused it to prevent future growth.

  • Testing and Air Quality: The need for safety testing and measures to improve indoor air quality can also add to the cost.

For an accurate estimate, it is best to consult a mold removal specialist who can assess the specifics of your situation.
