"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."

"Pure Restoration is a fantastic company! We contacted Pure Restoration because we had a leak in our ceiling and had suspected that we have mold, and so the company's owner, Tommy, came over with a team and confirmed it. Tommy helped us with our insurance claim and made the all process as easy and as pleasant as possible. We feel very lucky that Tommy and his team were there to help. Tommy personally took me to his suppliers to find the right wooden floors and wallpaper to match what I had and it was very important to him that I was happy with what I picked. It is really great to find such an honest and professional company and I will defiantly recommend and use them again."

"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."

"It went exceptionally well. Larry is the greatest. He worked very **** ** this project. His team that came to clean the property was very professional and friendly. I hope I never have another asbestos problem again, but if I did, or if someone I knew had one, I would definitely recommend Larry and All Clear again. Thanks Larry and Hector. This is a true statement and I stand by it. :-)"

Mold Testing and Remediation questions, answered by experts

Mold grows in areas with humidity levels above 60%, but ideal conditions for mold growth occur when humidity is between 70% and 90%, especially in poorly ventilated areas. To prevent mold growth, aim to maintain indoor humidity levels between 30% and 50% using dehumidifiers, proper ventilation, and temperature control. Regularly check your home's humidity with a hygrometer to help you monitor and avoid conditions conducive to mold.

While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

There are two types of mold symptoms in the home: visible mold and unexplained health issues. If you have allergies out-of-season, brain fog with no other obvious cause, constant congestion, and other such symptoms, you may have a mold problem. Oftentimes you can smell mold in your home, even if you can’t see it. 

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.
