"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."

"All work was completed on time with exceptionally high-quality work. All workers were introduced to me, making me comfortable with strangers in my home. All workers wore masks and used all health recommendations. I was brought into every step of the process and the process was explained. The total cost was as estimated. The price was about half of the estimate of other contractors. I was very satisfied. I recommend this business."

"This is my first time leaving a review for a company as I've never felt the need to, but using Pacific Environmental I feel I should share with my home owners. My husband and I bought out first home which we love but a room had acoustic ceiling. I reach out to PEAS, which everyone in the office was very helpful and patient on guiding me through this experience. Their scheduling was amazing as I was dealing with Closing Escrow and moving my family in. Once they arrived, they informed me on the scope of work and what they would be doing and what to expect, this being my 8-year-old son room so I was a bit worried on hazardous material that was being removed and used. CONTAINMENT WAS AMAZING! I was so happy and felt so safe on how they kept the area and the protection they took to take care of my family and themselves. My kids thought the crew looked pretty cool too, haha. CLEANING WAS AMAZING! Work was conducted upstairs and they went the extra mile and cleaned everything they touched, I really appreciate that, as it again made me feel secure and safe. PEAS left a memorial memory our kids still talk about. I strongly recommend them and would use them again."

"I had an excellent experience with Mold Dwelling Testing from start to finish. The inspector was extremely professional, knowledgeable, and thorough during the entire process. You can tell they genuinely care about helping people identify the source of mold problems instead of just rushing through an inspection. They took the time to explain everything clearly, answered all of my questions, and made me feel much more at ease about the air quality concerns in my home. What really stood out to me was how detailed and honest the assessment was. The testing process was quick, organized, and very professional, and I received my report faster than expected. The report itself was easy to understand and gave practical recommendations moving forward. It’s hard to find companies these days that combine great customer service with real expertise, but Mold Dwelling Testing absolutely delivered. If you need mold inspection or air quality testing in California, I highly recommend them. Rel"

"The expert who arrived to give an estimate on the job was punctual, friendly, very knowledgeable, and helpful. He recommended that I could simply do the de-molding of the car interior myself. He suggested what products to use and how to do it. He also advised me about how to avoid a similar problem in the future."

Mold Testing and Remediation FAQs, answered by experts

No, not all black mold is toxic. Although people often refer to stachybotrys chartarum as toxic black mold, there is little evidence that any one type of black mold has more toxicity than another. People who have an allergy to black mold would be more likely to have a dangerous reaction after inhaling it. Long-term exposure to black mold spores can lead to severe infection and disease. Some people only have minor health problems after black mold exposure. Ultimately, toxicity is rare with any kind of mold, but it is possible, so always take the appropriate precautions.

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

Thorough inspection, air quality tests, and surface sampling to detect mold presence and levels.

Several factors affect the color of mold, including humidity levels, age of the mold, and amount of light it receives. A patch of mold that starts out green may darken and turn black as it ages. A species of mold may be green if growing in one environment, but be black in another environment. Color usually isn't a reliable way to determine mold species or risk.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.
