"Jon came by for a consult to look at some ugly looking black staining that was growing in my basement. He was very professional and punctual and thoroughly explained why it was not mold, but harmless mildew and how to rectify it. I was so appreciative for his integrity and honesty and I will absolutely use Indoor Environmental if I ever do get mold in my house."

"Fantastic service. Had high mold counts for my Dads house. Other companies were 2-3 times higher and we had to vacate the house for 5 days. Rey came in treated the house and we were back the next day. Had an independent mold tester come in after remediation and the results were well below acceptable levels. My Dads health has improved dramatically and has changed his quality of life: Thank you Rey!"

"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."

"They do both mold removal AND restoration. (Not everyone does both!) They arrived when they said they would. Their pricing was 30% less than the next bidder. They explained what they were doing along the way. I even tried to fix Mateo up with my daughter."

"If we could give our technician, Paul, 10 stars we would. Paul was so conscientious and detailed in cleaning our sectional sofa. The floors were covered to prevent any residual spray products from getting on the floor. The house trim corners were protected from hose scraping. When the work was completed, everything was left in pristine condition. The company was good at communicating the scope of the job, sent reminders about the scheduled time & date, and thoroughly explained their pricing process."

Mold Testing and Remediation FAQs, answered by experts

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Yes, a one-time water leak can cause mold. Depending on the conditions, mold can begin to grow within 12 to 48 hours. The risk increases with the severity of the leak, high humidity, and when water soaks into absorbent materials like drywall. To prevent mold growth, stop the leak immediately and ensure the area is dried completely; running a blower fan for 24 hours is recommended. If you do notice mold, it's best to call a mold removal specialist to address the situation.

There are different types of mold, and not all humans are the same. For example, a more toxic type of mold may have less of an effect on a healthy person than a less toxic mold in the home of someone who is immunocompromised. If you recognize any symptoms of mold poisoning—sinus issues, brain fog, respiratory distress, constraint cough, migraines, or any others—call your doctor or go to the hospital before you attempt any removal.

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

You can find the smell of mold in your house in two ways: following your nose, and using common sense tactics like looking anywhere there’s water first. Mold cannot form in a completely dry environment, which is why you see mold much more often under kitchen sinks than on garage floors. If you have looked everywhere and still can’t find the source, hire a pro, because you may have mold in your walls.
