"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!"

"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!"

"My whole world crumbled when my bathroom leaked water down my walls and out of my ceiling. I didn't know what to do. I'm a new home owner and have never processed a claim through my insurance. Wes showed up to my house in all the mess. He was there within an hour of the issue happening. Not only did he and his company take care of the damage, they took care of everything with the insurance company. I was out of my home for over three weeks. My animals were displaced and I had to leave my kitties locked in the basement. They went so far above and beyond, they even fed and watered my cats! It was a stressful situation, but they took so much pressure off of me by handling everything! When I was finally able to go back home, not only was the water damage gone, my house was sparkling clean from top to bottom on both floors of my house. My house hasn't been this clean ever! It's like I walked into a brand new home. They updated me everyday. I never had to reach out, because they were in constant communication. I am so blessed this company came in and saved the day. The work was phenomenal. You better believe I have them saved in my phone. I was assured they do all manner of work my home could possibly need. Next time I need help with ANYTHING, I'm calling Wes at Plow and Property Projects!"

"for $50 we had an initial reading done, bought two Aerus Angel Air Scubbing/Purifying units, and now we can breath easily in our home again after a severe mold problem in the home was partly remediated (so far). The service was professional, prompt, and detailed. The products were worth the price for our health."

"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

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

The CDC does not consider diatomaceous earth toxic to humans or animals, though it can cause skin, eye, and lung irritation when handled without PPE. It's important to note that non-food-grade diatomaceous earth can be toxic when handled or consumed, so homeowners should only purchase the food-grade option.

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.

When you smell something, it’s because the particles of what you are smelling are floating through the air. If you smell mold, it means that it’s airborne, and whether or not it’s harmful depends on the type of mold. It’s very hard to tell the difference between molds, even with the internet to guide you. Call a professional as soon as you see mold, they will test it, remove it, and make sure you aren’t breathing anything harmful.

In most cases, it's not worth the risk of buying a home with mold. You should carefully weigh the pros and cons before making a decision—and there are far more drawbacks than benefits. For one, buying a house with mold opens you up to health risks since mold can cause respiratory and allergic reactions. If the mold is widespread throughout the home, the cost to completely remove it, make necessary repairs, and prevent it from returning is often not worth the cost savings of buying a mold-infested home for a bargain.
