"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!"

"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"

"My insurance paid Ivan directly for mold detection and remediation, which was completed quickly. We subsequently hired them to repair/remodel the entire bathroom, which they are in the process of doing (also as quickly as can be expected), in spite of having to deal with an extremely difficult and unpleasant tenant!"

Mold Testing and Remediation FAQs, answered by experts

If a professional mold inspector finds mold in your home, they’ll conduct mold testing to determine the type of mold species and the number of spores in your home. This plan will help develop a remediation plan, where a mold remediation specialist will remove the spores from your home. Since mold remediation costs the average homeowner $2,225, it’s best to treat mold at the first sign rather than waiting.

PVC is not considered a hazardous waste in most areas, but regulations vary by location. If in doubt, you should contact your local sanitation department to confirm. The Center for Biological Diversity (CBD) has been working to get PVC classified as hazardous waste, so it’s possible that it will be considered as such in the near future. If it is, disposing of PVC will require the use of a hazardous waste disposal facility or transporter in your area.

Yes, by identifying allergens and implementing measures to mitigate exposure.

Once again, contact with moisture is the culprit here, though water-resistant varieties of wallpaper are less likely to become wet and develop mold. Using a high-quality exhaust fan or dehumidifier and leaving the doors or windows cracked after bathing will keep this issue at bay. 

Mold in HVAC ducts is a relatively common issue that homeowners struggle with—especially in humid climates or homes with poor ventilation. Moisture from condensation, combined with dust and organic debris, creates the perfect environment for mold growth. Homes with high humidity, leaky ducts, or clogged drains are more prone to this issue. Regular inspections and proper HVAC maintenance significantly reduce the risk of mold developing in your ducts.
