"I had a great experience with this company when I needed mold removed from my home. From the initial inspection to the completion of the work, everyone was professional, courteous, and knowledgeable. They explained the process clearly, answered all of my questions, and kept me informed throughout the job. The team arrived on time, worked efficiently, and took the necessary precautions to protect the rest of my home. They did a thorough job removing the affected material and cleaning the area, and they left everything neat and clean when they were finished."

"We hired Jeff to give us pre and post mold remediation air quality tests, and I am so glad we did. Jeff was extremely knowledgeable and had no conflict of interest on the outcome of the results since we had a different company doing the remediation. We actually had to go back to the mold remediation company when his air quality report did not pass clearance, and he was our chief advocate in getting the company to come back and do further remediation. He has been a great to work with because he is not only an expert but is a caring individual, and I would recommend anybody use his services. He also is licensed to test for asbestos, which is our next project before we remove our popcorn ceiling!"

Mold Testing and Remediation FAQs, answered by experts

Touching toxic mushrooms will generally not cause harm unless you consume them. It's important to thoroughly wash hands after handling any type of mushroom to prevent accidental ingestion.  

Yes, mold behind drywall can affect your health, even if it is not visible. Mold releases spores and mycotoxins into the air that can be inhaled, leading to various health issues including respiratory problems, allergies, asthma symptoms, coughs, and other infections. While individuals with pre-existing conditions like allergies, asthma, or weakened immune systems are particularly vulnerable, anyone can be affected by prolonged exposure. Additionally, if left untreated, mold can spread throughout your home and compromise its structural integrity, resulting in costly repairs.

The most common reason for a smelly dishwasher is a dirty dishwasher filter. The filter is responsible for catching food while your machine is running to prevent clogs. Over time, that filter gets more and more filled with food particles. Cleaning your dishwasher filter monthly can keep the smell at bay.

Mold thrives in high-moisture environments, whether that’s steady leaks or just high condensation. Around the house, common causes of mold include leaky pipes, a leaking roof, high humidity, poor ventilation, a damp basement, rotting food in the fridge, wet clothing and towels not hung properly for drying, a leaking foundation, and a leaky air conditioner.

And, of course, if your home suffers from flood damage, you stand the risk of developing mold in the aftermath. That’s why it’s important to act quickly at the first sign of mold.

The primary difference is that black mold (Stachybotrys chartarum) is considered toxic and more dangerous than regular mold. It can produce harmful chemicals called mycotoxins, which may lead to severe health issues like respiratory problems, skin irritation, headaches, and other long-term complications. While regular mold is rarely toxic, it can still cause allergic reactions and respiratory irritation. Visually, black mold often appears dark—green, gray, brown, or black—with a fuzzy texture, whereas regular mold can be almost any color. Black mold is less common and typically grows in areas with severe water damage. Regardless of the type, you should not ignore any mold infestation in your home.
