"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

Bathroom tiles can contain asbestos, just the same as patio tiles or kitchen tiles. Remember that asbestos was used primarily for its insulative and fire-resistant properties, both of which are desired in a house. Before we knew asbestos caused cancers and other diseases, it made a lot of sense to include it in many different building materials, including bathroom tiles.

Mold loves moisture, so prolonged high humidity levels or standing water can trigger mold growth. Mold also needs a food source to grow on, such as wood, fabric or another material. However, it's moisture that's most important for mold growth, which is why you want to keep humidity levels low.

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.

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.

Yes, limewash is free of volatile organic compounds (VOCs). Made of lime and water, it is eco-friendly, breathable, and toxin-free. Most synthetic paints have low to high levels of VOCs, which causes their irritating odor, which can have adverse and long-term effects on your health. Conversely, limewash consists of crushed limestone, which undergoes burning, mixing, and aging before being diluted with water—natural pigments add coloration.
