"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."

"Overall was good for what the service is. The technician was a postal worker and home inspector. So mold test company appears to be brokers. Their pricing was competitive from other quotes I received but I honestly think it was pricey for time spent and what they do. But like I said the price was pretty standard from the companies I called, in my opinion. But the technician was attentive and knowledgeable, and friendly."

"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 questions, answered by experts

Window sill mold can be harmful, but the severity depends on the type. Common household molds like Cladosporium or Aspergillus can trigger allergies, respiratory issues, or worsen asthma symptoms. However, black mold (Stachybotrys) can produce mycotoxins that can harm your health. Even less toxic molds should be addressed promptly to prevent health risks and property damage.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Frequently, fungi have a gray color with a powdery or fuzzy texture on a wall. In showers, fungi and mildew may resemble a pink slime. Meanwhile, toxic mold may resemble a fuzzy growth on walls that’s often black or green in color. Some toxic black mold will have specks of orange or white on it. However, not all dark-colored mold you find on a wall is toxic. An infestation of toxic mold often will spread faster than fungi on walls. If you are unsure whether you have toxic mold, reach out to a professional for help.

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

Common causes include water leaks, settling, and impact. Address underlying issues to prevent recurring damage.
