"Of course, I had mold. I was surprised at how quickly they recommended Biocide to eliminate my mold problem. I feel like they may be together in the mold removal industry. Having done my research, you are not supposed to have a mold test company and also be a mold removal company, and yet this company seemed to skirt that but not having them be officially affiliated with Mold Test Company."

"Once contacted, Gregory Paxson provided timely and very professional mold and remediation services. Besides finding mold in several areas of the home, he also discovered the cause of the mold. All of the damaged materials were removed which allowed the plumbers to repair the water leaks that were causing the mold. Mr Paxson then was able to remove and replace the damaged insulation in the crawl space. During that work, he also discovered an additional structural problem that had to be addressed. In summary, Mr Paxson successfully completed removing the mold, conducting microbial remediation steps, replacing the damaged insulation, and installing a new crawl space vapor barrier ."

"I can't say enough about Joe and Frank. They know their business. The mold problem was remediated quickly and efficiently at a reasonable cost. I highly recommend Failsafe, they were neat, clean, and safe. The containment area was impressive with negative air pressure maintained to avoid spreading spores. This is a big job, with multiple aspects to repair the crack in the outside wall to prevent further issues. Failsafe accomplished its portion flawlessly. The mold and musty smell is gone."

"CSI was flexible and was able to schedule a home inspector the day after I got a bid accepted on a house. The inspector, Patrick, showed up on time and the inspection took about 4 hours. Patrick was responsive to any questions I had by email or live during the inspection. My one recommendation is that I requested a pest, mold, radon, and home inspection. It would be a better heads up if they explained that they sometimes outsource the radon inspection depending on availability of radon inspectors. Also, they can explain a bit more for new home buyers what is involved with a mold inspection. Patrick ended up just eyeing whether he spotted any mold. Because he did not see any mold, we did not have to pay extra for mold samples."

"Remedia-Pro arrived on time as scheduled, talked with me about what I wanted them to do, and gave me a price upfront. They did a fabulous job--our 8-year-old, pet-stained berber and plush carpets looked like new when they were done. They also offered tips on how to treat stains immediately to keep them from setting in. Great experience, will hire them again!"

Mold Testing and Remediation FAQs, answered by experts

Toxic mold doesn't have a specific color; instead, toxicity depends on the type of mold and the mycotoxins it produces. Stachybotrys chartarum (also known as black mold) is notorious for its potential toxicity. However, not all molds appearing black are Stachybotrys chartarum. Mold species that appear in various colors, such as green, gray, brown, or black, can also produce mycotoxins. Therefore, it's essential to focus on identifying the type of mold through professional testing rather than relying solely on color to determine its toxicity.

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, it is common for mold to grow on the underside of the siding due to the moist atmosphere. When there is an abundance of moisture, mold has the ideal environment to spread and thrive. This fungus can be found on virtually any surface, both indoors and outdoors. Generally, it is most active when the environment is warm, damp, and humid.

The answer to whether it’s safe to use a moldy dishwasher is: It depends. Mold exposure affects people differently. It’s possible that even a small amount of mold in your dishwasher could contribute to respiratory issues and other health problems, especially if you have an underlying health condition. Mold is capable of surviving the high heat and detergent used in a dishwasher cycle, so it’s important to ensure that you act quickly at the first sign of mold, or contact a house cleaner near you to stay on top of any potential mold problems.

Painting over mold is not an effective solution and can actually make the problem worse. Instead, it traps moisture, which allows mold to grow and spread beneath the surface. Mold must be completely removed before painting to ensure the problem doesn’t recur. If mold is painted over, it may eventually seep through the new layer of paint, causing discoloration and peeling.
