"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

If a professional mold inspector finds mold in your home, they’ll conduct mold testing to determine the type of mold species and the number of spores in your home. This plan will help develop a remediation plan, where a mold remediation specialist will remove the spores from your home. Since mold remediation costs the average homeowner $2,225, it’s best to treat mold at the first sign rather than waiting.

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.

Mold can damage the surface it’s growing on, cause mold-related sickness, and even affect your upper respiratory system.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. Whether mold develops depends on several factors, including the severity of the water damage and how quickly the area is addressed. To prevent mold, you must act fast—ideally within the first 24 hours. The process involves cleaning up all standing water and thoroughly drying the affected area. If the damage is extensive, the cleanup was delayed, or you suspect mold might be present, it is safest to assume it has grown and contact a professional mold inspector or removal expert to assess the situation.
