"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!"

Dark mold growth, while common, can cause allergic reactions and various symptoms even when in the attic.
Great project which ultimately lowered the indoor humidity by 20% making it more livable for the family, storage where there was none previously, and much more healthy from and indoor air quality perspective (no stinky bacteria).

"Excellent! It is a Family owned business. Matt is very personable and explained everything with the whole process. I needed someone right away, and he genuinely seemed like he wanted to help. He fit us in his schedule immediately, even right before Memorial weekend. We got results very quickly, within 2-3 days and we were able to move along closing on our house. I would definitely recommend them as well as the testing for your home."

"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!"

"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."

"Professional and top quality service from beginning to end. Robert, the sales rep, inspected our attic and instantly identified the root cause of our mold problem, matching what a separate inspector also ascertained. He worked with us to provide a fair price for a comprehensive solution that remediated the mold while also recommending an approach to the root cause. What is great about Green Attic is that they are able to handle it all...saving me time and money from having to go through separate companies to piece together the full solution. Communication throughout the entire process was timely, consistent, and pleasant. The crews who came to do the work were obviously experienced and went out of their way to ensure I was kept up to date on progress (showing me before and after pictures along the way). These guys worked hard in tough conditions and made me feel confident the job was completed to spec and with attention to detail. I couldn't be more pleased!"

"Had a leak after some bad storms. Paul determined it was from a bad window frame. Came out and replaced it with vinyl , walked the rest of the roof to look for any other issues as well. Caulked around a chimney, replaced some flashing, and of course sealed around the new frame. He was very professional, and came in under his bid! I would highly recommend 360 Restoration."

Mold Testing and Remediation FAQs, answered by experts

Sampling typically takes 1-3 hours, and depending on the provider, lab results are available within 2-7 days.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

Mold can begin to grow in as little as 12 to 24 hours, especially if the room is warm, so drying the area is the first thing you should do after water damage. Because mold and mildew can cause a range of health issues, make sure you clean up any water damage as soon as possible and run blower fans and dehumidifiers for 24 to 72 hours to dry out the room and reduce the risk of mold growth.

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

In most cases, cloudy tap water is safe to drink, as the cause is often harmless air bubbles. A simple test is to let a glass of water sit for a few minutes; if the cloudiness dissipates, it was likely just trapped air. However, you cannot be certain of the water's safety without knowing the cause or performing a water test. If the cloudiness is persistent, comes with yellow or brown discoloration, or is accompanied by plumbing issues, it may pose a health risk. In such cases, it is best to call a local plumber to find the cause.
