"We spent some time live with molds and we don’t know it was mold. We are trying 2 times to clean it out with some cleaning companies, but it was useless. Finally we got lucky with Bio 911- very professional, sharp, deeply attentive for details, even for our lifestyle depending on appearance of mold and compared with other not expensive. Thank you very much for Bio 911 and personally Kirill for outstanding work."

"Our landscaping in Menlo Park needed a complete refresh. The team replaced thirsty plants with drought-tolerant options that still provide plenty of color and curb appeal. We're using much less water without sacrificing appearance."

"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."

Biohazard Remediation questions, answered by experts

Mold removal will take between one and five days in most cases, but severe mold issues can take several weeks to correct. Your timeline will depend on how much mold there is in your home, where the mold is located, and how much testing and aftercare is required. If you have mold behind your walls or you have an excessive amount of mold that requires removal and running air scrubbers for several days, you could be looking at over a week for the process to be completed.

Bleach will kill green and black types of mold, but isn't always the best choice. Vinegar can be a more effective mold killer, as it can penetrate surfaces, killing mold beneath. If you have a large area of mold, it's best to hire a mold remediation company to take on mold removal.

Yes, you can save moldy wood furniture by removing the mold as soon as you notice it. Mold can penetrate and damage porous wood, though, so waiting to clean it could lead to significant damage. If a large coverage area of mold grows over several months, you may want to ask a professional to try to save the piece. If the damage is bad enough, though, even a pro might not be able to save it.

DIY cleanup is not recommended due to hazardous soot, odors, and potential structural issues.

Yes, many professional cleaning services include mold and mildew removal using safe, non-toxic solutions.
