"Charles Schwartz was available immediately for us when we called. We met him the next day, and he did an extremely thorough mold inspection/assessment of the house we were planning to buy. He tested the surfaces and the air for mold. We were able to determine what type of mold it was, where it was located, the extent of the problem, the cause of the problem and a plan to remediate. He was highly professional and scientific. He was patient with us, available to answer our questions, and thorough in his report. We felt very much able to trust his advice, and now have a plan in terms of moving forward with what we will need the seller to do in order to properly remediate the problem. We would definitely highly recommend his services."

"Gary was kind enough to come in on a weekend to get the testing done. Not only was he thorough in his work but also in explaining everything. We received the results back within the time promised. Since then he has still been quite helpful in answering questions and quick to respond even though his job has been completed. I would highly recommend MoldXperts, not only for the great work and customer service, but it was the most reasonably priced company around."

"I highly recommend G-Tech Restoration as an outstanding company. We recently discovered mold in our kitchen and the damage was extensive; finding a reputable company to do the mold remediation seemed daunting. After doing some research, we were so fortunate to come across G-Tech; Don called right away and Jack came to inspect the following day. We met with three different companies and in the end, G-Tech stood out far and above as the company that was genuinely concerned about getting our home back in order as quickly and painlessly as possible. Everyone we encountered was extremely professional, on time every day, and we were never left hanging, wondering what and when the next step would be. Pretty much half my house had to be packed up: every single item, from my large furniture, down to the smallest knick knack was treated with complete and utter respect. Every precaution was taken, as far as sealing off the affected areas and putting in air scrubbers, to ensure that we and our children were living and breathing in a safe living environment while the mold was being remediated. Everything was resolved in a timely, efficient, professional manner and now that we can begin putting our home back together, they even come back and move our furniture back into the house! Once again, I highly recommend G-Tech Restoration as a company of extremely knowledgeable professionals who actually care about the comfort and well-being of their clients. In my encounters as a homeowner, this is an extremely rare quality and I’m so grateful that we worked with them."

"Angstrom Testing used a moisture meter and found that one of the kitchen walls and an area of the kitchen ceiling in my mom's apartment were wet. Then they took an air sample in the kitchen and sent the sample to the lab to determine the level of mold in the air. After that, they made a cut into the wet area of the kitchen ceiling and found a dripping water pipe. The top side of the ceiling was black with mold. They also took a piece of sheetrock out of the top of the wet kitchen wall and found more mold on the back of the wall (yuck!!).
They called me two days later with the air test results, and they told me that the level of mold in the air was very high. They also told me that there was probably a connection between my mom's symptoms and high levels of mold in the air. Makes sense. They also told me that that my mom should stay upstairs with me and my husband until we get rid of the moldy ceiling and wall in her apartment.
A few days after they called, Angstrom emailed me a report with all of the details of what they did and found. In the report, they wrote recommendations and procedures that a mold removal contractor should follow to safely remove the mold and dry and treat the wood wall frames and wood ceiling. Since the level of mold in the air was so high, they said in their report that the kitchen air should be cleaned with an air cleaner and that the kitchen appliances, cabinets, and floor should be wiped down to get rid of all the mold spores that were laying around.
I really appreciated all the work they did and all of the advice that they gave me to help me and my mom. My mom is now living upstairs with me and my husband, and she says that she is already starting to feel better. Although my husband is not too happy (LOL). Great company! Thanks.

Ground water infiltration occurred through the concrete slab in two rooms on the ground floor of the house causing water damage and mold growth on the overlying flooring. The cause of the water infiltration appears to be associated with cracks and a crater in the concrete slab, which is believed to have been caused by pile driving work being performed during the construction of an adjacent building.
Mold in HVAC Coil Compartment
Construction/demolition work in an  apartment unavoidably released high levels of dust that migrated into adjacent apartments. Dust containment methods, such as negative air filtration and poly sheeting, should have been used to prevent dust migration into adjoining spaces. Settled dust samples were collected from a table & curtain rod in a nearby apt, which revealed the presence of substantially elevated levels of silica and asbestos in the dust. Asbestos and silica are known carcinogens.

Mold Testing and Remediation FAQs, answered by experts

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.

PVC is not considered a hazardous waste in most areas, but regulations vary by location. If in doubt, you should contact your local sanitation department to confirm. The Center for Biological Diversity (CBD) has been working to get PVC classified as hazardous waste, so it’s possible that it will be considered as such in the near future. If it is, disposing of PVC will require the use of a hazardous waste disposal facility or transporter in your area.

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

Telling the difference between poisonous and nonpoisonous mushrooms is difficult even for trained mushroom experts and biologists! However, nature provides some red flags for poisonous mushrooms. Assume that any mushroom with a red cap or stem is poisonous. You should also assume mushrooms with white gills, rings, skirts, or a sack-like base are poisonous.
