"Jessie came a week earlier to estimate the problem and cost. He was punctual and thorough in the entire process. He and Tim cleaned out the mildew and moisture and cleaned up after resolving the issue so that my contractor can come to fix the leak problem. They were above and beyond polite and worked fast to keep the area controlled. Sanitized everything again before leaving. I would use them again and highly recommend them."

"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."

"I literally cannot say enough about Our experience with EnviroFry. Divine and William went above and beyond in doing our mold removal project, including adding on a significant additional project (our workshop in the basement which leaked for the first five years we lived in the house). They have excellent knowledge related to mold remediation, were dedicated and caring, and were willing to go more than the extra mile. Hire them and you won?t be sorry!"

Mold Testing and Remediation FAQs, answered by experts

Mildew starts as a tiny spot, but if left untreated, it can severely damage your home as well as cause life-threatening health issues. Mildew eats away materials like wood and drywall and if left untreated can destroy entire walls and buildings. Mold sickness is almost a guarantee if you don’t tackle this problem as soon as it rears its head.

If you notice water accumulating in your vent due to a roof or plumbing leak above your ductwork, it's essential to promptly identify the source of the leak and undertake any required repairs without delay. Such leaks have the potential to swiftly result in water damage within your home, ultimately leading to mold and mildew concerns.

Pellet stoves burn compressed wood byproducts, making them very efficient and clean-burning. However, even efficient combustion still produces fine dust particles, which could have an effect on the health of vulnerable people in your household, such as infants and people with asthma. A wood stove pro can help determine whether the levels in your home are unsafe.

You normally won’t see any dust or mold actively floating out of your vent, but you might notice your vent looks dirty. Mold will cling to the sides and collect almost like black soot. Dust will look, well, dusty, but there will usually be a heavy buildup so expect thick gray layers on the bottom and sometimes the sides of the vent. If you suspect you have mold in your vents, call a professional immediately.

Through air sampling devices and surface swabs in key areas of concern.
