"Did mold remediation in 2020 before house was purchased. Mold found in attic. Resolved it with a 4 year warranty expiring 3-23-24. In January 2024, found mold in same spot. They inspected and sent an estimate to remove. Asked about the warranty still in place. Never responded. Did a good job of remediation work. Doesn’t support their warranty."

Toxicity and mold removals FAQs

Mold remediation can last indefinitely if you eliminate the underlying moisture problem that caused mold growth. That’s why it’s essential to repair leaks, reduce humidity, and remove water-damaged materials to prevent mold from returning to your home. Be sure to keep up with regular maintenance and inspections to help prevent future mold growth.

It's generally not recommended to stay home during mold remediation, especially if the infestation is extensive. Mold spores can become airborne during removal, posing health risks. It's best to relocate temporarily while professionals remove the mold and restore your home. Some contractors may require occupants to vacate to ensure safety and efficiency.

Mold can return after remediation if the underlying moisture problem isn't fully resolved. To prevent mold from coming back, it's essential to identify and repair the source of moisture, such as leaks, high humidity, or poor ventilation. Without addressing these issues, mold spores can find the damp environment they need to grow again. Ensuring that your home remains dry and well-ventilated is key to preventing future mold growth after remediation.

Unfortunately, exposure to mold can lead to various health effects, especially in individuals with allergies, asthma, or weakened immune systems. Common symptoms include nasal congestion, throat irritation, coughing, wheezing, eye irritation, and skin rash. Some molds produce mycotoxins, which can cause more serious health issues like respiratory infections or neurological problems. Prolonged exposure to toxic molds may even contribute to severe conditions such as lung disease. It's important to address mold problems promptly to protect your health and well-being.
