"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."

"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!"

"The whole experience was amazing! When Eric came to look at the house he explained everything to us so we would understand the process and what to expect. He let me know how common this happens and it even happened to him recently which made me feel better. They were super efficient, quick, and caring. They even use green products which is a plus having a pet. I would recommend them to friends family and anyone else who needs their help with the services they provide. Very affordable for us and money well spent! Thank you so much for making the house feel more comfortable and the air so much cleaner!"

"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

You can kill slime mold with organic fungicides and commercial products like BioSafe Disease Control. However, the following substances will also get rid of slime mold: baking soda, potassium bicarbonate, cornmeal, cornmeal tea, and hydrogen peroxide. Typically, these fungi are cosmetic and rarely harmful to plants, so it’s OK to wait it out. The matter will disappear in a few days to two weeks.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.

Mushrooms do not harm your yard. In fact, they can actually help improve your lawn health by decomposing woody organic matter in your soil, and breaking it down into nutrients that feed your grass and plants.

You can do a basic home water test, but we recommend having a pro conduct a more in-depth test. This method is accurate, and you’ll have a pro who knows your house helping you determine a plan of attack for anything out of the ordinary.

Vermiculite insulation can be hazardous if it contains asbestos. Asbestos fibers, when released into the air and inhaled, can pose significant health risks. The EPA recommends leaving vermiculite insulation undisturbed to avoid potential exposure. It is crucial to have vermiculite insulation tested by a certified professional to determine if it contains asbestos. If asbestos is present, proper precautions should be taken, including containment or removal by licensed abatement professionals.
