"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

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

Homes built before the 1990s may contain asbestos, but the only way to be sure is to have your home tested. Hire an asbestos testing and removal service to determine whether you have the hazardous material in your home and the best process for removing or sealing it.

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.

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

Beyond looking for visible signs of mold in a home, you can tell if your house has mold by undertaking testing. You can hire a local mold testing company to run the test for you, giving you a sure answer. Professional testing is often the best way to determine whether you have mold, as some types of mold may grow in places where you can’t easily see them, such as behind walls.
