"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."

Mold Testing and Remediation questions, answered by experts

Yes, if installed correctly. Moisture barrier padding blocks dampness from reaching the padding core and subfloor, where mold loves to grow, especially in humid environments like basements. However, poor installation with gaps or loose seams can do the exact opposite, trapping moisture and creating mold problems. So, make sure to do your installation carefully or hire a professional.

It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.

Visible growth, musty odors, and water damage are common indicators.

Yes, mold can grow on virtually any porous material, including plaster, and can be a pain to get rid of. If you see any signs of mold or mildew growth, call a local mold inspection company to take a look—mold is a health hazard and can spread quickly to other parts of your home.

Seeing black dots around the air vents is alarming, but don’t worry. It’s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months.
