Dark mold growth, while common, can cause allergic reactions and various symptoms even when in the attic.

"This company is great to work with. They did some mold testing on parents’ home and did excellent work. They also did some work on my home. They replaced a water heater and bathroom fans. He was easy to get a hold of, personable and come over right away."

"I had Brett come to our home to test for mold because I’ve had an ongoing illness that Drs can never diagnose. He was so caring & did the testing within days of talking to him the 1st time. After the testing, he explained everything in detail and provided a list of things to improve the air quality in the home. I have never dealt with any type of contractor that was as thorough and really had our best interest at heart. He was honest, upfront with cost and I felt like I could totally trust him and his recommendations. If you are in need of mold or air quality testing, call Brett. You will be completely satisfied with his knowledge and care to make your home “healthy” again."

"I am extremely satisfied with the mold inspection and remediation services! The team conducted a thorough inspection of the entire property, used professional equipment to measure moisture levels, and clearly explained where the issues were located. After we agreed on the scope of work, they promptly began the remediation process: everything was done carefully, using safe products, and they provided a detailed report with before-and-after photos. The entire process was smooth, on schedule, and stress-free. I especially want to highlight their high level of professionalism, attention to detail, and willingness to answer all my questions. Now the air in my home is fresh again, with no unpleasant odors. I highly recommend this company to anyone looking for reliable mold specialists!"

Mold Testing and Remediation FAQs, answered by experts

While the resistance of lime to mold is a hotly contested topic of debate, it is true that because it allows porous materials to breathe, it avoids trapping moisture close to the structure of a building. This breathability makes it less susceptible to mold than paint because it gathers less moisture.

While the air inside your home should have some moisture—the ideal humidity level is between 30% and 50%—too much moisture can lead to issues. Some ways to tell if there’s too much moisture in your home include condensation inside your windows, mildew growth in the bathroom or mold on surfaces, peeling paint, or an uptick in allergy symptoms.

Yes, mold can grow on nonporous surfaces. Mold is extremely resilient and can survive just about anywhere. However, mold will not grow as quickly on a nonporous surface as on a porous one. Additionally, the nonporous nature makes it easier to remove. Keep the countertop clean and properly maintained, and you shouldn’t experience mold growth.

No—there are key things that help you determine if it’s mold versus mildew. Mildew is a specific type of mold. Both can trigger allergies, asthma, and respiratory symptoms, though mold is typically more severe than mildew.

Hazardous waste is waste that poses a threat to human or environmental health. This generally refers to waste that is flammable, corrosive, toxic, or reactive. To confirm if the waste you need to remove is considered hazardous waste, contact your local hazardous waste facility.
