"Abatement and Remediation are not for the weak or weary - whether managing a personal or professional project, proper containment practices and efforts are essential. I will forever recommend and promote All Clear Environmental - a family-run business with hands-on customer relations. Larry Enos and his son, Beckett, put forth great effort to communicate, assess, and manage the process in good faith. All Clear's team of Rigo et al, handled the physical abatement and remediation, in our home. Rigo and his team made us feel 100% safe, confident, and secure throughout each stage - which was no easy feat with children and pets, in a home. And while there are no accolades for being second-round mold recipients, we hit the jackpot in working with All Clear. We have worked with other companies only to be left with poor communication, a tendency to be overcharged, and dishonesty. Beckett was available almost 24/7 to answer questions via text and live calls. When I felt doubt, Beckett made time to discuss alternative avenues and ensure our best interests were at the forefront of every decision. I recommend All Clear Environmental to friends, neighbors, and strangers with 6/5 stars. Your house is your home - and mold is personal. A company that recognizes the need to love your home well, is a gem beyond measure. Thank you, All Clear Environmental - good people attract good people! Gratefully, Jackie"

No, it isn’t. This is one of those things that needs to be dealt with immediately because mold will spread at a rapid rate and can go from just one spot on the wall to a serious health risk in a matter of days. Prolonged exposure can be extremely dangerous, so any mold issues (or even suspected mold) need to be dealt with right away.
The negatives of a humidifier are the potential for mold growth due to high humidity levels, the up-front cost, and the energy requirements to run it. Depending on the state of humidity in your home, you may not actually see lower utility bills due to the humidifier running on a near-constant basis.
Yes, mold on wood furniture can be dangerous, especially if it is identified as black mold. Inhaling spores or touching mold can make some people sick with respiratory issues, skin rashes, and eye irritation. However, some people have mild or no symptoms after exposure to mold. If you are going to clean mold off wood furniture, you should wear protective equipment to avoid direct exposure.
Costs depend on test type, home size, number of testing locations, and whether follow-up testing is required.
Yes, drywall mud can get moldy—though the presence of moisture is required for this to happen. That’s why the best way to keep your powdered drywall mud fresh for as long as possible is to keep it in dry storage conditions. If you live in a humid area, it might not make sense to stockpile a lot of powdered drywall mud before you’re ready to use it. As for premixed drywall mud, avoid opening the container until you’re ready to use it—and don’t expect it to last longer than six months.
