"Lifetime radon service did a great job of explaining the process of installing the remediation system as well as options we had to help control the costs of the project to within our budget. They were also flexible and allowed to replace the sump pump on our own prior to installation so that we were able to install the model of sump pump that we wanted."

"Great company to work with! The service was great from the beginning of the process to completion. It was easy to work with their scheduling of the project and their electronic payment system. I had lots of concerns about having the asbestos tiles removed from my basement and I had lots of questions. Harrison took the time to explain how the project would be handled, he was very patient with me in answering all my concerns so that I felt confidence in hiring EnviroGo. The crew doing the work showed up at the time they said they would and the technicians and supervisor were very personable and professional in explaining how they would prep the area to do the containment. I was happy with the respect they showed to my property and the finished work. I received the Air monitoring test results about 24 hours after the work was completed and all was good. I would hire EnviroGo again if I had another project that needed this type of work."

Biohazard Remediation FAQs, answered by experts

Tree sap is not usually dangerous to humans or pets. But some trees do produce dangerous sap. Notably, ash, birch, cedar and similar saps can irritate the skin but aren’t dangerous. Sap from trees like the Brazilwood, Mahogany, Milky Mangrove or well-named Poison Walnut can be corrosive, cause nausea, or trigger those with asthma. But for most backyard trees, protective equipment like a sturdy pair of gloves should be fine.

Black mold often smells musty, stale, or earthy, and some people liken its scent to that of sweaty clothing. While not everyone can identify the smell of mold, you are likely to smell it before you see it, as it usually is hidden in dark, damp areas; instead, the scent may pervade your entire home. If you smell mold, start by opening windows and looking for the source of the smell. If you find mold or are concerned about side effects, call a mold specialist right away, as it can be almost impossible to get rid of yourself.

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

Mildew is a type of mold that forms in areas of excessive moisture and poor ventilation. Although it commonly exists in household air, it can’t take hold and spread if a surface is clean and dry. Generally, if you have any mildew or mold issues, it’s because the humidity in either your house, room, cabinet, or cupboard is above 50 percent. Common areas where you’ll find mildew are around water sources, which is why it’s commonly found near showers and in kitchen sinks.

In most cases, it is safe to return home after mold remediation is complete. You should follow your mold remediation technician’s recommendations, but most pros request that homeowners wait one day after the process is complete to move back in.

After returning home, be sure to carefully inspect the exposed areas for any remaining signs of mold spores. Contact the mold remediation company if you detect any lingering mold.
