"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!"

"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!?"

"We have a cold room for adhesive storage and had a horrible case of mold due to an incorrect build out. I called these guys and they came out very quickly. They removed all of the mold along with infested ceiling tiles and paint the fell off of the wall during the process. They left the walls looking new again and cleaned their mess. We have not had a mold issue since. I highly recommend these professionals!"

"They came, they saw, and they conquered! I had a sewer back-up in the utility room of my home, and had put kitty-litter to help absorb backup. Although it initially helped, it created its own mess when even more had to be put down because of additional backup. To be honest, wasn't sure if HydroForce was up to the task, especially when they had to finish up on another day. But, HydroForce proved not only to be up to the task. but did an awesome job! They cleared, cleaned, and disinfected the floor and the surrounding appliances to the point they would be affected by the back-up. The only thing I did expect that wasn't done was the use of an air scrubber or purifier because of mold/mildew concerns with water backup. However, the job they did was impressive and I will recommend them for future use."

Mold Testing and Remediation FAQs, answered by experts

In mild cases of mold growth, you can DIY mold remediation with a simple cleaning using safe and natural cleaning solutions like baking soda, hydrogen peroxide, vinegar, or lemon juice. However, if the mold is larger than 10 square feet or you suspect toxic black mold, you should not do mold remediation on your own. Instead, you should hire a professional mold removal company to handle the job.

Yes, drywall mud can get moldy—though the presence of moisture is required for this to happen. That’s why the best way to keep your powdered drywall mud fresh for as long as possible is to keep it in dry storage conditions. If you live in a humid area, it might not make sense to stockpile a lot of powdered drywall mud before you’re ready to use it. As for premixed drywall mud, avoid opening the container until you’re ready to use it—and don’t expect it to last longer than six months.

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.

It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.
