"I cannot say enough about Abide Inc. They were professional, timely and knowledgeable and do fantastic work. I had them do a quote consultation and testing for a mold issue and asbestos abatement and they were prompt to make room in their schedule to fit us in and kept every word of their agreements throughout their Process. Chris Coopee did a fantastic job reviewing reports needed plus conducting a physical inspection of the property for mold in order to produce an informed accurate quote. He also is knowledgeable about asbestos abatement and conducted some testing at the site for us. Not only did Chris do a perfect job, but he turned around the ask in a tight timeframe due to our needs related to a real estate closing. Ann at the main Abide office fielded many questions from me throughout the week and was always pleasant and helpful. I highly recommend consulting this company for any remodeling or remediation needs. This is a great company with great people. Kudos to them!"

"Excellent service from everyone at Mold Busters - from the estimate through completion of the mold remediation in my basement. Very fair pricing. Hopefully, I won't need mold remediation again, but if I do, I Definitely will hire Mold Busters!"

"This company is great at what they do. Used them twice. They helped removed asbestos tile and mold from my basement. They were quick, clean and most importantly got rid of the "bad stuff". They did such a good job the first time that I called them again when i unfortunately found mold in my crawl space. Both times eradicated all traces of mold. Would gladly use them a third time if needed!"

"Quick, efficient, good description of product. Definitely listened to our issue. However, more ficus put on resolving air issue than finding the root cause. We are happy with the units we purchased."

"Luis and his crew did great work removing large areas of adhered corkboard wall from two rooms. They were efficient and handled the removal, the drywall spackling and paint priming with minimal residual residue or mess in the house. The finished walls were just what we had hoped for. They were all a pleasure to work with! Communications via texts and the app made it easy to ask questions and follow up anytime."

Mold Testing and Remediation questions, answered by experts

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

Costs depend on property size, test types, and additional services like mold sampling.

Telling the difference between poisonous and nonpoisonous mushrooms is difficult even for trained mushroom experts and biologists! However, nature provides some red flags for poisonous mushrooms. Assume that any mushroom with a red cap or stem is poisonous. You should also assume mushrooms with white gills, rings, skirts, or a sack-like base are poisonous. 

According to the EPA, mold allergies are common and can cause skin irritation, respiratory problems, headaches, and other allergic reactions. Mold allergies can also trigger asthma attacks in people with asthma. Additionally, some molds produce mycotoxins, which can lead to very serious conditions, like lung cancer.

Water damage occurs when your property or items suffer damage due to excess and unwanted water or moisture. The water could be present due to a natural disaster such as a hurricane or a burst pipe—water damage can be caused by many things. If necessary, contact a local water damage restoration company.
