"My husband and I are writing to communicate to you a very positive interaction with Brian. His professional approach to mold remediation, which was mandatory in the conduction of the sale of our home, displayed a knowledgeable background, as he also educated my husband and myself, as to the mold clean-out process. His service was stellar!?"

"I contacted them yesterday for Mold Remediation services. I would recommend reaching out to this company for this type of service. I spoke to the owner and he was kind enough to talk me through my problem over the phone. He was completely honest up front and told me how to solve this issue on my own without spending any money. The other 2 companies I called for this service wanted to charge me a large amount upfront and I would have ended up wasting a lot of money if I hadn’t spoke to the owner of Illinois Mold Eradicator. It’s hard to find honest people now a days, I would highly recommend anyone to use this company as their first choice!"

"Rapid mold services and Augustin were absolutely amazing!!! We had extensive mold in our kitchen and they worked endlessly to remediate it all while keeping costs as low as possible. They worked in a timely manner, kept us up to date and educated through everything they did, and had excellent communication. I would recommend them time and time again!"

"I had a water leak from my ice maker. The water line had a pin size hole in it and was leaking downward thru the floor. Once I realized the issue. I had a 6x6 section of flooring to be replaced. I also had sub-flooring, drywall and insulation that needed to be replaced. My insurance suggested I bring in a specialist. Because of the potential of mold. I called Patrick at Mold Removal & Solutions. Patrick came to the house the same day and gave me a quote. A couple days later Patrick started working and was finished in about three days. This is the second time I used Mold Removal and Solutions. Patrick and his crew were always on time and professional. I would recommend Patrick to anyone."

"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."

Mold Testing and Remediation FAQs, answered by experts

The signs of asbestos exposure are often subtle and may not appear for many years, or even decades, after initial contact. This long latency period is one of the primary dangers associated with asbestos.

When symptoms do manifest, they can include:

  • Shortness of breath

  • A persistent, dry cough

  • Chest pain or tightness

  • Fatigue

  • Wheezing

  • Weight loss

  • Difficulty swallowing

  • A dry, crackling sound from the lungs when breathing

These symptoms are non-specific and can be mistaken for other respiratory conditions, making diagnosis challenging. Prolonged exposure can lead to serious diseases as the asbestos fibers cause scarring and inflammation in the lungs. These conditions include asbestosis, lung cancer, and mesothelioma.

Due to the vague nature of early symptoms, regular medical check-ups are crucial for anyone with a known history of asbestos exposure, particularly in an occupational setting. If you suspect asbestos is present in your home, a professional inspection is recommended.

While bathroom mold, commonly known as black mold, does not produce harmful mycotoxins, it can still pose health risks. If disturbed, mold spores can become airborne and potentially cause allergic reactions, respiratory problems, skin irritations, and other health issues. This is especially true for individuals with allergies or sensitivities. While bathroom molds are not as dangerous as other mold species, prompt action is crucial to mitigate health risks and prevent further spread. 

Mold is a fungus that typically grows in warm, moist environments, which is why it's so often found in bathrooms, attics, and under sinks. It survives by digesting decaying organic materials, which makes it very helpful for removing dead plant matter around the world. However, if it starts eating away at your drywall, window frames, and flooring, it can harm your home and your health.

Most mushrooms found on residential lawns are harmless. Certain varieties such as destroying angel, fly agaric, and vomiter mushrooms that can grow in grass will occasionally make their way onto residential lawn, but this is uncommon. Since mushrooms can be notoriously difficult to identify, if you suspect that your lawn mushrooms could be a poisonous type, consulting a professional is recommended.

Not all molds are inherently harmful, but their presence can lead to health issues, especially for individuals with allergies or respiratory problems. Black mold often garners attention due to its potential toxicity. However, other molds can cause health concerns too. Regular mold, appearing in various colors like green, gray, brown, or black, can trigger allergies and respiratory problems. Prompt removal and prevention measures are essential, regardless of mold type, to maintain a healthy indoor environment.
