"The guy was really helpful but I couldn't afford what he charged me at that time. Otherwise I thought that they are a pretty good company. The guy who came out was really informative and helpful. As a matter of fact we had sewer damage and he had suggested about to claim with the metropolitan sewer industry. He was really pretty knowledgeable and very professional. The estimate was for around $4500 to $5000. It would have been well worth it but I couldn't afford it at that time. I think he was excellent personally. He was here when he said he would be here."

"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."

Mold Testing and Remediation FAQs, answered by experts

Yes, a refrigerant leak is extremely toxic and dangerous to breathe. Refrigerants can displace oxygen in a room, which can lead to suffocation, loss of consciousness, serious health issues, and even death. You may also suffer from refrigerant poisoning, which can cause symptoms like headaches, nausea, dizziness, swelling of the throat or sinuses, vision loss, and a burning sensation in your eyes, ears, nose, lips, and tongue. If you experience any of these symptoms, you should seek medical attention immediately. In addition, refrigerant leaks are toxic to the environment and can cause permanent damage to the ozone layer.

Some of the most common signs of sensitivity or illness from mold include congestion, eye irritation, difficulty breathing, and headaches. These symptoms may not lead to long-term health issues. However, some types of mold, like toxic black mold, can make you quite ill. You may experience respiratory issues, skin rashes, or neurological issues after exposure because of the toxicity. Infants, people with compromised immune systems, and older adults can suffer the most severe reactions.

Mold in a basement is harmful as it can trigger allergy symptoms, especially for those with asthma and other breathing conditions. Symptoms of mold exposure include itching, sneezing, running nose, and congestion.

Mold can begin growing in as little as one to two days after your ceiling has been exposed to water. Mold grows and spreads quickly and can cause serious health problems. Always ensure areas with leaks are fully dried out, and any damaged material is replaced to discourage mold growth.

While an air purifier can trap mold spores and stop them from spreading around your home, it’s not the most effective solution for tackling the problem. Mold is caused by excess moisture and humidity, so there’s a good chance you have an issue somewhere else in your HVAC system that needs to be addressed.
