"Ted from Biotek noted that since I had already done some home project work, the fix needed was actually something I could do myself. He gave great feedback on the root problem for moisture continuing to build up was the lack of a hose feeding to a vent from the bathroom fan, and that a simple dryer hose running to an existing vent exit in the attic would help on that front. He then gave steps on using a vinegar solution, elbow grease, and letting the area dry for several days (avoid that shower) after killing the existing mold, before applying a layer of mold sealing primer (like Killz). He saved me at least $2500 compared to some quotes I'd received to take care of the problem."

"I received the kit and sent the swabs in due to the virus. Results came back very quickly and were informative and consistent with my expectations.. The agent called and gave a very thorough explanation of the results. The cost was reasonable; it would have cost more had they come in to do the work. this was no hard sell. I have not yet completed the mold remediation."

"I would recommend this company for asbestos abatement. I was very grateful that they were able to help me in such short notice to remove the asbestos when another company did not show. I thought their price was pretty fair and was told by the mold testing company that they do good work. I would not hire this company to do anything else. I was in a bind and got a quote on what it would be to mud and paint the ceiling and paint the house. I was very very unhappy with the quality of the work of the painters he hired. I feel I should have been deeply reimbursed or discounted because the paint job was so bad. They got plaster everywhere on my kitchen cabinets and are unable to remove it so I must just look at it. They did not replace some of my lights and there are cracks in the seems and every worker I have comments on how bad the paint job is. Very dissapointed that I spent so much money for that. They came out to try and fix it and it was not even fixed. Maybe a little better on the ceilings. It was extremely hard to get the electrician that I hired through them to come up and finish the job here in Charleston. I believe he lived a few hours away and everything was just a headache. He was unable to find a certain part and I ended up having to research and find it online. We lost at least a week while he was looking for that."

"Greg and his employees did an amazing job!! From start to finish it took three days and if you had saw our crawlspace I didn't think anything could be done. Our crawlspace went froma dark, dank, moldy, snake infested, armadillo incubator to a space that is as clean and seems as hygienic as a hospital operating room. I would not go anywhere near our crawlspace before and now have no issues crawling anywhere I want or need to go under the house. they even went beyond by adding some lighting and fixing our airhandler so it didn't drain under the house anymore. I highly recommend Greg and his team at Crawlspace Doctor to turn your space into what it was meant to be."

"It turned out well. I used it shortly after I purchased the deal. There were additional charges beyond the big deal amount as I had them repair something that they found while doing it. They did everything as advertised and then in addition to that, they also fixed some molding around the chimney that had become cracked and weathered. I had not used them before. There have been no issues since the service was provided."

Mold Testing and Remediation FAQs, answered by experts

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

Yes, air duct cleaning can remove mold from the interior lines of HVAC systems. Professional air duct cleaning companies use tools and methods like brushes, cleaners, and vacuums to remove mold from air ducts. For successful mold remediation, it is essential to hire a reputable and experienced air duct cleaning service. Keeping your air ducts clean can also help prevent the conditions that allow mold to grow and thrive in your ductwork.

Air purifiers are meant to kill airborne mold, along with pollen and dirt. Air purifiers are a good option if you have allergies and need a whole-home solution, whereas dehumidifiers are best for naturally damp areas (like a bathroom). Consider getting an indoor air quality test to determine if an air purifier is right for you.

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.

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.
