"Quacker's Waterproofing was wonderful. When they came for the estimate, they were fast and no nonsense. They weren't trying to convince me of things that needed doing or dramatizing the work for more money. When I had questions about the work, they didn't make me feel dumb but took extra time out of their day so that I had peace of mind with my foundation. I hope to never need their help again, but I will definitely call them if I do. Special kudos to Rob!"

"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."

He surveyed the area and took samples in 20 minutes. Then, he explained the process for mold remediation in great detail. He was courteous and thorough."

Mold Testing and Remediation FAQs, answered by experts

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

No, you can’t place hazardous waste in a dumpster unless you specifically ordered a dumpster for hazardous waste removal. If the dumpster company finds hazardous waste that it didn’t approve for dumping, the company will return the waste to you, and you’ll likely face a fine for illegal dumping.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

Professional carpet cleaning can cause mold if the job is not done properly. There are two ways this can happen—if your carpet cleaner fails to dry the carpet properly, or if your carpet cleaner uses an excessive amount of water during the cleaning process. Mold can grow wherever moisture is present, so make sure you hire a pro who knows the process inside and out.

It is not advisable to stay in a house with black mold. Exposure to black mold, or any mold, can lead to health problems, especially for vulnerable individuals such as children, the elderly, or those with weakened immune systems. Black mold produces mycotoxins, which can cause respiratory issues, skin irritation, fatigue, and headaches. If black mold is detected, it is crucial to evacuate the premises, seek professional help for remediation, and only return once the area is thoroughly cleaned and confirmed mold-free by experts.
