"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 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!"

"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."

"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."

"When I went looking for flooring at a local store, the man said there was a good chance the tiles and glue were asbestos. My research indicated I could just cover the floor (encapsulate it) or remediate it. Even though it was expensive, I thought it best to remediate it. I used Angi's which is what I ALWAYS do and looked up service providers. I called a couple of them and got prices. Environmental was not the cheapest, but Maximus made me feel comfortable. He not only reviewed what needed to be done in the basement, he advised me about other things, as well. I felt like he really knew what he was doing, and he spent time with me. He gave me options, and I think he went above and beyond."

"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

Visible growth, musty odors, and water damage are common indicators.

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Silverfish aren’t a direct sign of a mold problem. But since they like dark, damp locations, they’re a very strong sign that mold problems could exist. That’s why it’s important to look for signs of mold while you are taking care of a silverfish problem, and fix any causes of long-term moisture in your house.

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.
