"Our attic developed mold after years of small roof leaks that we kept patching temporarily. LeakSafe Homes handled the mold remediation in our Calabasas home with incredible professionalism. They removed contaminated insulation, treated the wood framing, and helped us understand how ventilation contributed to the issue. Very knowledgeable company."

"We were happy to find Tommy and his crew. We had some water damage in the lower level of our home after the heavy rains this year. We had mold in the carpet and water coming in through the porous tile. Tommy gave us a fair quote and their staff handled the process professionally. There were no surprise charges and the crew showed up on time and the office quickly responded to our emails. They did the build back after the mold remediation and we could not be happier with the way it turned out. They did a beautiful job. I highly recommend Pure Restoration if you are dealing with a mold takeover in in your home!"

"We hired Hippo to do an air quality check in our apartment because we were worried about mold and other allergens that are causing health problems for my husband and I. Daveâ s son came out and was SO knowledgeable and did an excellent job of explaining everything he was checking for and what all of the numbers meant. He was very thorough and gave great recommendations for next steps as well. The whole process was so easy and theyâ re very professional. They also check for more than just mold, which I found a lot of other inspection companies around us donâ t check for. Would definitely hire Hippo again!"

"Alex was great from the first time I called for a quote. I hired Alex and his team for Asbestos Abatement and mold remediation. Alex and his team were professional and were a pleasure to work with. What impressed me the most was their integrity. After their job had been completed there was something our painter pointed out to us that required for them to return and they came back as soon as they could to fix the issue. They were a pleasure to work with and their price was more than fair compared to others."

"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."

Biohazard Remediation questions, answered by experts

Some mold can look like dust, but most doesn’t. Powdery mildew is often confused with dust as it’s a similar color and grows in a similar way. Some gray molds can look like dust as well, but usually, it’s pretty easy to spot the difference. It’s better to be safe, so if you aren’t completely sure what you’re seeing is dust, call a mold professional to check it out.

Follow recommendations for removal or remediation to ensure a safe living environment.

No. When dry, mold enters a dormant state. While “sleeping,” the mold won’t multiply, but when it encounters moisture again, it springs back to life, releasing spores. That's why it's crucial to not only control humidity but also actively eliminate mold to prevent its resurgence and further growth inside your home.

The necessary frequency of mold cleaning in your home will depend on several factors, including the climate, the presence of moisture sources, and the type of siding. It's generally recommended to inspect your siding regularly and clean any mold growth as soon as it appears to prevent it from spreading or causing damage. If you’re not sure how often you should clean mold off siding, you can always contact a siding contractor near you to consult on what maintenance schedule will work best for your home. 

When soffits aren’t vented, the airflow can’t infiltrate your attic space which results in stale air trapped inside. Over time—sometimes very quickly—that trapped air can result in a moisture sink, causing rapidly growing mold issues throughout the home. You should generally avoid covering or fully closing off soffits, even in the winter months, as the ability to circulate air is far more important than the meager increase in heating costs.
