"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."

"After a disappointing experience with another remediation company that left us with lingering mold, we were fortunate to have Alex come to the rescue! From the start, he impressed us with his professionalism and thorough approach. Alex not only identified the areas the previous company missed but also explained his entire process, ensuring we knew what to expect. He worked meticulously and left no corner unchecked. Thanks to Alex, our space is now completely mold-free and feels fresh and healthy again. We’re so grateful for his expertise and dedication—wish we had called this company first! Highly recommend, especially Alex!"

"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"

Mold Testing and Remediation FAQs, answered by experts

Nearly all homes have at least some airborne mold spores. If you want to determine the concentration of spores in the air, you have a few options. The most effective option is to hire a professional tester who can take air samples of the home. The tester would send the samples to a laboratory to determine the concentration of mold spores. 

The high humidity of steam showers creates the ideal environment for mold growth, so it’s important to stay proactive against it. Along with regular cleaning, run your bathroom fan during and after your steam shower. Keep your shower door open and any doors and windows in the bathroom to allow the space to air out properly. If you come across ugly mold spores, spray them with undiluted vinegar, let it sit for at least an hour, and then scrub away the mold.

If you believe mold is hidden somewhere in your home, don’t delay inspecting it, as it can be dangerous, especially to people with breathing problems and allergies. While it’s possible to learn how to check for mold yourself, we advise most people to hire a professional mold inspector, who can look more thoroughly. You can also purchase mold test kits if you aren’t sure if your home has mold, but a true human inspector is still your best bet.

If you find black residue in your toilet tank, chances are it’s caused by manganese deposits from hard water and not mold growth. You can prevent these deposits from damaging your toilet by installing a water softener in your home, which also might improve the quality of your drinking water. You can also remove the deposits inside your toilet tank once every six months or so to prevent them from causing problems with toilet functionality.

Signs of mold under silicone caulk include discoloration or dark spots appearing through or around the caulk, a musty odor in the area, and visible growth on the surface of the caulk. Additionally, if the caulk feels soft or spongy, it could indicate moisture trapped underneath, which is a breeding ground for mold.
