"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 FAQs, answered by experts

Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.

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.

Mold damage devalues a home in two ways: monetarily and emotionally. The numerical amount of mold damage devaluation can be 20% to 37%, which is substantial when house prices are often over $250,000. The second factor to consider is the emotional one: many buyers are hesitant to purchase a home that either has, or had, significant mold damage. For these reasons, it’s very important to deal with any mold issues immediately.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions. Mold releases spores into the air, and inhaling these spores can cause symptoms such as coughing, sneezing, eye irritation, and skin rashes. It's important to address mold issues promptly to protect your health.

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.
