"Noah scheduled an estimator to come to my house 30 minutes after my phone call. Moises came and gave me a reasonable price. He was prompt and courteous. The next day Hiram and Orge came to do the work. They were prompt and friendly. They did an excellent job removing the mold. Brian called me to keep me appraised of what they did and how long they will be leaving the dehumidifier and other drying equipment in the garage. This company is prompt, professional, and courteous and did an excellent job. I would definitely use them again."

"Ongoing water intrusion from our windows over the years led to mold issues throughout several rooms in the house. After bringing out three different companies to evaluate the situation, Steven and the team at Nexgen Property Restoration stood out right away. They were fair on pricing and offered a non insurance discount since we chose to handle everything out of pocket. With multiple areas needing to be opened up, that savings really helped. The remediation process was handled professionally from start to finish and the quality of work gave us the confidence to move forward with them for reconstruction as well. Having one company manage everything made the process a lot easier. The final result came out great and their warranty gives us peace of mind moving forward. Definitely recommend Nexgen if you?re dealing with paying out of pocket"

"SavOn/Ivan came out immediately and tested the area in question. I had mold in my dining room ceiling, not airborne thank God; but mold none the less needing remediation. SavOn completed the remediation in about 4 days and were very thorough, professional and attentive. Taylor in the office and Ivan in the field provided excellent service. SavOn was a little pricey but not as astronomical as the other companies. My project is not yet completed due to a lack of funds on my part but the cosmetic repairs will be completed soon and I'll keep you posted on the progress. Angel A"

Mold Testing and Remediation FAQs, answered by experts

In most cases, it is safe to return home after mold remediation is complete. You should follow your mold remediation technician’s recommendations, but most pros request that homeowners wait one day after the process is complete to move back in.

After returning home, be sure to carefully inspect the exposed areas for any remaining signs of mold spores. Contact the mold remediation company if you detect any lingering mold.

Black mold appears in areas with constant moisture and has a slightly fuzzy texture. It’ll have a primarily circular pattern. While it’s known to have a black color, it can also appear dark green, or dark brown, although a few types include orange or white flecks. Identifying black mold is important because people who inhale the spores could suffer respiratory issues or neurological problems. Black mold is a toxic material and requires a professional to remove it.

Both an air purifier and a dehumidifier can help prevent future mold growth, but neither can remove existing mold. An air purifier will improve air quality and trap mold spores in the air, whereas a dehumidifier will reduce moisture in the environment. Keep in mind that you need to make sure your air purifier uses HEPA filters, which are rated for mold removal.

EIFS has several disadvantages, primarily related to cost and moisture. The system tends to have higher upfront installation costs compared to other siding options, and repairs can also be expensive, especially if water damage occurs. A significant downside is its low breathability, which can trap moisture between its layers from either leakage or condensation. This trapped moisture increases the risk of developing mold and rot, which can lead to costly and extensive repairs if not addressed promptly.

It’s unlikely your leaves are a hazard, especially if you get to them while they’re dry. However, a couple of rare risks exist. University studies suggest that decaying leaves can produce organochlorines, toxic pollutants similar to man-made PCBs (polychlorinated biphenyls), so avoid keeping them in an enclosed area.

Also, leaves and compost may cause the growth of fungi that can cause diseases like histoplasmosis and aspergillosis, as well as mold spores that are unhealthy for human lungs. Again, severe issues are rare, but those with compromised immune systems or allergies to mold should wear face masks when directly handling leaves.
