"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

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.

Yes, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.

While water in your basement is unlikely to make you sick unless it’s coming from a sewage backup, mold is likely to start to grow in wet areas within 24 hours, and mold can make you sick. According to the Centers for Disease Control and Prevention (CDC), inhaling mold spores can cause allergy symptoms, including runny nose, itchy eyes, difficulty breathing, wheezing, and itchy skin. Individuals with pre-existing respiratory issues like asthma and immunocompromised individuals are at an elevated risk of symptoms when inhaling mold spores.

Although mildew is less harmful than mold, that doesn’t mean it’s safe. Breathing in even small amounts of mildew can cause serious health complications, especially in those with weakened immune systems. If you find any mildew in your home and can’t completely remove it easily (and there are elderly or sick people living there) you should call a professional right away.

If the smell is closer to mildew or rotten eggs, the issue is probably mold or bacteria buildup in the machine or its drainage system. Clean your washing machine thoroughly, paying close attention to the rubber door gasket, as it can harbor odor-causing residue. Some machines have lint or debris filters that should also be checked and cleaned according to the user manual's instructions. Be sure to leave the machine's door or lid open after each use, as this allows for better air circulation and helps prevent mold growth.
