"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."

"Very professional and knowledgeable!! Had a leak in my roof and didn't realize it until the dreaded mold was everywhere!! Called Moisture Solutions and the guy came out and quoted me a price that i felt was very reasonable. He cut out all the mold, treated the "whole" house, and it was very quickly. Very impressed with "Josh." I highly recommend this company!"

Mold Testing and Remediation FAQs, answered by experts

White mold is generally considered less harmful than black mold, which can be more toxic due to the mycotoxins it produces. However, white mold can still be harmful, particularly for individuals with mold allergies, asthma, or other respiratory conditions. Exposure can cause symptoms like nasal stuffiness, throat irritation, coughing, or skin irritation, and it can exacerbate existing health issues. Because any type of mold can pose health risks, all mold infestations should be treated seriously. Prompt remediation is necessary, and you should take proper precautions, such as wearing protective gear and using appropriate cleaning agents, when dealing with it.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

If you believe mold is hidden somewhere in your home, don’t delay inspecting it, as it can be dangerous, especially to people with breathing problems and allergies. While it’s possible to learn how to check for mold yourself, we advise most people to hire a professional mold inspector, who can look more thoroughly. You can also purchase mold test kits if you aren’t sure if your home has mold, but a true human inspector is still your best bet.

Professionals use specialized equipment and techniques to detect asbestos, radon, and VOCs.

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.
