"Working with Lee and his team has been a truly exceptional experience! I personally had mycotoxin so I understand the dangerous and debilitating effect mold can have on peopleâ s lives. We hired Lee and his team for mold inspection when we were considering buying a house. We contacted Lee when we were on day 3 of our 10-day inspection period. Despite his busy schedule, Lee squeezed time to come by the house. Professional and patient, Lee answered all my questions with expert knowledge regarding the test results and the proposed remediation plan. The house we were trying to buy doesnâ t have mold to an alarming level, but I was determined to rid of them for my familyâ s health. Lee and his team did an excellent job for the remediation and they shared so much professional knowledge with us, which I greatly appreciate. We liked their work ethic so much that we hired them again to do HEPA vacuuming for the house after some remodeling projects. Again, Lee always patiently answered every single one of my questions with great depth of knowledge. We had some issues with contractor delays and Leeâ s team was very understanding and accommodated our updated schedules several times with their very busy schedule. The ozone treatment has greatly reduced the odor from remodeling, which was already minimal from using zero VOC paint and flooring. Again, we liked their work so much that we asked for their help to deodorize our new car. Lee and his team are exceptional not only in their expertise knowledge in mold but also their work ethic; they are punctual, they prepare their clients before each visit, and they follow up after each visit. We cannot say enough praise about Lee and his team!"

"We discovered we had mold in our home after we had a leak. Matt and his team tested our home for mold, then we completed the dry fog remediation treatment. They gave me post tests to show the mold has all been killed. They were very thorough everything went just as planned. Excellent job, I am very impressed!"

"The tester was well versed in this area even showing the areas that were high in moisture. Very friendly and informative as well as professional. Made me comfortable with the experience she had. When the owner and maintenance worker failed she made me comfortable. Fae who had the credentials as well experience explained everything in detail. Definitely use Fae!!!"

"We had a water damage issue at our home and when Nexgen Property Restoration opened up the walls it turned into a much bigger problem than expected. They found mold and other issues we had no idea were there. Their team handled everything from remediation to drying out the house and made the whole process smooth. They worked directly with our insurance company and got everything covered which was a huge relief. They even helped us out by waiving our $2,500 deductible which says a lot about how they take care of their customers. They may be a newer company but they clearly have years of experience behind them. Highly recommend Nexgen Property Restoration you won?t regret it."

"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

Yes, it is generally unhealthy and can be dangerous to live in a damp basement. The damp air can negatively affect your breathing and lungs, and the moisture promotes mold growth and pest infestations. Inhaling mold spores or waste particles from insects and rodents attracted to the moisture can be hazardous. This damp, moldy air can also circulate into your main living area. It is crucial to resolve any moisture problems and implement preventative measures before using your basement as a living space.

Signs you may need mold remediation include visible mold growth on walls or ceilings, a persistent musty odor, or health symptoms like allergies and respiratory issues. Areas affected by water damage or excessive humidity are prone to hidden mold. A professional inspection can confirm whether mold remediation is required, especially for large or concealed infestations.

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

In some cases, black stains on brick are caused by organic substances like algae and mold. However, it's more likely that the black spots you're noticing on your bricks come from carbon from vehicle exhaust or soot. Black stains can usually be removed by scrubbing the brick with a brush and masonry cleaner or power washing.

Mold on window sills is common, especially in damp or poorly ventilated areas. Windows are prone to condensation, which creates the moisture mold needs to grow. Dust, dirt, and other debris on the sills can further feed mold spores. While it’s not unusual, it should be addressed quickly to prevent further growth and potential health risks.
