"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!"

"Green Home solutions is a God send. The home I bought had mold from in the attic main level and basement. Dustin gave me such a good price, half of the other quotes. They came right out and within two days all the mold was gone and my new home smelled great! I have the peace of mind that my family is safe! And best of all the product is a non toxic enzyme and Dustin guarantees the mold will stay gone!!"

"Plow and Property has completed several projects for us on a very old and neglected rental property and we are so glad we found them. The first job was a vacant house clean out. The house was left in truly appalling condition. The cleaning crew worked and worked and worked so hard and so long I was telling them to stop. They made a filthy house fresh and pleasant again. I would not have thought it could be restored to such a fresh condition. The next job was replacing the old casement windows which were rotted wood frames in crumbly 1950s cement. They not only repaired the window foundation area but other foundation ugly spots as well and put in beautiful new sturdy basement sliding windows. They also re-dug and replaced the adjoining window wells which were undoubtedly the original wells and were falling apart. Regraded the foundation area around the wells and reseeded without being asked. While they were in the basement doing the windows they cleaned a bunch of that up too so it’s no longer a horror movie waiting to be filmed down there. Everything they did was simply above and beyond. Wesley Vercosa has returned my many questions and concerns with lots of information and smiles, bless him. My retired husband worked in construction for many years and he is happy and impressed with the work. We are planning more work with them already. We have multiple properties and I think we have found our new property manager."

"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."

Mold Testing and Remediation FAQs, answered by experts

Toxic drywall has a sulfur smell, similar to rotten eggs or poop. It’s often a sign that the drywall mud is expired, there’s mold or mildew growth, or there’s a leak in your home. Drywall can also absorb moisture during storage, transportation, or installation, resulting in a distinct musty odor.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Although you can run a DIY test for mold inside your home by buying a test kit, you won’t know whether the strain of mold is dangerous. The best way to test for mold in a home is to hire a professional who can determine the specific type of mold that you have. If you’re worried you exposed yourself to mold and it’s making you ill, you could request a health test. Your personal doctor could test your urine, take a nasal swab, or test some body tissue to determine your potential exposure to mold.

Mildew and mold are not different—mildew is a specific type of mold and yes, it can become dangerous if left untreated. It would be amazing if we were all biochemists but because we most likely aren’t, it isn’t wise to assume any mold is mildew on sight alone. Harmless mold and toxigenic mold (which can be deadly) look very similar, so if you see any new mold that looks even a little suspect, call a mold professional immediately.
