"Gary was great. He called me immediately upon reaching out to him via text. He scheduled an appt quickly. Gary was sincere about my feeling with my concern about my mold concerns. He explained what he was going to do, when I can expect my results and pending the results of air quality test, remediation steps. I would recommend Gary."

Customers say: True professional

"No one wants to find mold in their home (or in our case, the home we were buying), but everyone wants to find good, reliable, knowledgeable people to help them, and Johnnie definitely fits the bill. We were referred to Johnnie and got him on-site the very next day he was very accommodating. He spent a ton of time not only carefully working in the house, but gave generously of his time to explain things to us thoroughly. He was very honest, gave us his unfiltered assessment based on his expertise (which we appreciated), and we can not recommend him enough. If you are looking for someone who is personable, reliable, reasonably priced, and really good at their job, hire him, you will not be disappointed."

"From the first discussion with owner, Rob Ky, I felt confident that Certified Mold Removal Inc. was the right company for the job at my residence. From the actual testing of the mold, air samples, and everything is between-they were very thorough and efficient. Each and every associate that I worked with was not only extremely professional but genuinely cared about rectifying the situation that myself and my family were dealing with. They quickly and efficiently remediated the mold that was in and under the flooring in my home. Tom and his crew went above and beyond to make sure that I understood the process and was satisfied with the end result, which was of course no more mold! This was more than just throwing bleach on the floor and calling it a day, they made sure that the mold was completely cleaned and removed from the floor so that my family could return to a safe and healthy home. They even went as far as to fog the house so that any remaining mold particles were removed from the air. Mold remediation is extremely stressful and while I hope that I never have to go through this again, I would absolutely go to Certified Mold Removal, Inc. Thank you again for all your help and guidance throughout this process! 10 star service!"

"I had an issue in my son?s bedroom where mold kept forming on the ceiling and started spreading. We reached out to Safe Home Mold Remediation, and they came out the same day for a free inspection and provided a very fair estimate. We had already received three other quotes, and they were by far the most affordable option. On top of that, the quality of their work was excellent. They were professional, efficient, and made sure everything was properly handled. Very happy with the results?highly recommend Safe Home Mold Remediation."

"If more people were as honest, sincere, and caring as this man. I know this planet would thrive. Besides being a professional and clearly a true expert in this area, he explained everything clearly. Took his time and did not rush was patient and made me feel Safe. In the end, the mold testing he did showed I did not have elevated mold, prior to him I had a guy come in and told me he had a machine that tells if you have mold and he said I have 80% mold and I did not have to bother to do air samples. Be careful people. Other scammers out there. Andre is the Best you can trust what he says. Good luck."

"Prompt response, friendly and courteous. Clean - explained everything before and during the process. It seems to have significantly reduced mold - post test report shows mold levels in normal range. Much more comfortable in family room. Dave and Matt very easy to work with and quite professional. Highly recommend them."

"Jeremiah came out and tested the air and moisture and other items to determine if I had mold in my basement. After getting the test results there was evidence of mold and he recommended a company that provides a do it yourself kit for mold remediation. (Not cheap). After getting the items and realizing that there was more work, it would have been better for me to let my insurance company handle this as I do have coverage for mold/fungi. Though having a professional do the work is expensive, from what Jeremiah mentioned, it does not guarantee that the work will be complete or the source of the problem taken care of. He mentioned most companies will take care of the mold but not necessarily the cause of the mold. For this I would have to contact another company."

Mold Testing and Remediation FAQs, answered by experts

Symptoms of sewer gas poisoning include nausea, dizziness, extreme drowsiness, and headaches, according to the Wisconsin Department of Health Services. Exposure to higher concentrations for long periods of time could also lead to unconsciousness due to a lack of oxygen, aka suffocation. If you think you’ve been exposed to sewer gas for a dangerous amount of time, seek medical care immediately. Do not return to the site of exposure, after you’ve received medical care, call a pro for help.

Both an air purifier and a dehumidifier can help prevent future mold growth, but neither can remove existing mold. An air purifier will improve air quality and trap mold spores in the air, whereas a dehumidifier will reduce moisture in the environment. Keep in mind that you need to make sure your air purifier uses HEPA filters, which are rated for mold removal.

Mold grows quickly. It typically begins to grow on drywall about 24 hours after exposure to moisture or humidity. Drywall is a porous material, which makes it particularly hospitable to mold growth. 

While mold growth begins after just a day or so, it can take a few weeks before the evidence becomes visible. Mold spores will typically appear on the drywall surface within three weeks of growth starting.

If you suspect black mold is inside your walls, do not punch a hole in the drywall yourself to look. Call a mold inspection expert to help you. Some signs of a potential black mold infestation inside the wall include an unexplained musty, damp smell. Some people liken it to rotting vegetables. You may smell it most strongly through a wall outlet. If you and your family are experiencing constant coughing or symptoms that feel like an unexplained allergy, it could indicate black mold behind a wall.

Dehumidifiers do not directly remove mold or spores from the air. However, by lowering the room’s humidity, spores are less likely to flourish when landing on surfaces.
