"Mold test took air samples inside and out after we discovered some questionable spots that worried us. Samples are sent to a lab for analysis. We subsequently purchased a mold remediation kit from another firm and treated the house. We are breathing easier now. Thanks!"

"Very well. Will serviced the house. He suspected there could be mold in the ducts, because there wasn't any in the furnace itself. I had burning sensations in my eyes and throat and that usually is generated by mold. The burning continues, so I'm not sure there was a mold issue, but I'm glad I had the service done just in case there was. Will is very professional. Explained everything that he was going to do. He left the house in the same condition as when he arrived. Also, he was quick to say that if I had any problems in the future, he would be glad to come back."

"Upon submitting the request for quotes on mold remediation I was contacted by Dave within hours to 1 day. I had a consultation scheduled with Dave within the week. I can not attest to the testing services of All Mold & Basement Services as I had the testing done prior to submitting the quote requests. Dave was very professional and forward with his process. While their process is very similar to others on this site, they go the extra mile and use a dry ice blasting technique to remove and eradicate the mold from all services and even between the joists and flooring which other companies could not guarantee would be done. Because of this process they weren't the lowest quoted price but the end result was the wood looked BRAND NEW. Both my wife and I were astonished. There were some delays in getting started and finished however this was not due to the company but adverse weather. With close to 1,600 sqft needing work and in meeting the agreed upon deadlines some areas appeared to had been missed and were brought up with Dave. He personnaly came out with one member of his crew and the necessary treatment materials and immediately took care of the questionable spots. I can't speak highly enough of Dave and his folks and I would highly recommend this company if you have need of mold remediation work."

Mold Testing and Remediation FAQs, answered by experts

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

The negatives of a humidifier are the potential for mold growth due to high humidity levels, the up-front cost, and the energy requirements to run it. Depending on the state of humidity in your home, you may not actually see lower utility bills due to the humidifier running on a near-constant basis. 

Slime mold isn’t toxic to your dog, even if they eat it. Toxicity and comfort are two different things, and if you notice your dog eating slime mold, you should stop them, but not worry too much. Expect a period of gastrointestinal distress, and possibly some other complications, but your dog should be ok within a few days.

Mold damage devalues a home in two ways: monetarily and emotionally. The numerical amount of mold damage devaluation can be 20% to 37%, which is substantial when house prices are often over $250,000. The second factor to consider is the emotional one: many buyers are hesitant to purchase a home that either has, or had, significant mold damage. For these reasons, it’s very important to deal with any mold issues immediately.
