"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!"

"Going for a refi and the appraiser noticed mold on the ceiling in a bath. It's a vaulted ceiling. I needed to remediate the mold to close on the refi. I called Southside Mold Testing & Cleanouts and within a week, the mold was remediated. Brian and his crew were professional, prompt, and fair with pricing. Hope I never need this service again, but if I do, I would not hesitate to call Brian to do the work. What I thought was going to be a nightmare turned out to be pretty painless. Would highly recommend. Thanks!"

"I had a water heater leak that contaminated a 4x5 room with mold. RMS came over and thoroughly explained what they can do to fix it. They were punctual and also informative while they worked which made my wife comfortable with their work. The mold is gone and my family is safe. I would hire them again if ever needed."

"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!"

"Max just left my home and I already know he is the person to make our home safe! He will pack out our basement, remove mold, and remediate asbestos. I couldn’t be more happier! We are also looking for him to epoxy the floors."

"Michael showed up right on time at 8AM, removed damaged drywall, inspected for moisture or signs thereof, reinstalled drywall, and did a marvelous job on painting, and blending with the rest of the room so there was NO contrast between where he worked and other areas. Quote and timeliness of work were EXCEPTIONAL. Office staff was friendly and helpful. I definitely would recommend anyone to use GCPRO."

"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

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

DIY kits are available for basic air quality testing, but professional services provide more comprehensive results and recommendations. While a DIY kit may seem cost-effective, a professional assessment is more thorough. Inspectors are better equipped to catch all pollutants and hazards, and you'll still need a professional to verify and act on DIY test results. Furthermore, some kits don't test for certain pollutants or only detect their presence without measuring specific levels (like mold spores). It's generally better to opt for a detailed professional assessment.

While it isn’t as dangerous as black mold, pink mold in the shower or elsewhere still poses some health risks, particularly for people with compromised immune systems. Even if you’re in good health, pink mold could cause an infection if it gets into your eyes or penetrates your skin through an open wound.

Slime mold can thrive for weeks or months in the perfect environment, but that rarely occurs. The mold will typically die within a week of you noticing it. However, it could be dead long before it disappears, and since it’s safe to handle, it’s easier to get rid of it all at once. This eliminates its chance to spread, and also won’t leave you looking at decaying slime mold.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.
