"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."

"Larry answered my call and explained why we have no need to remediate what was safe in its present condition, notwithstanding the re-roofing we are about to perform on the house. In other words, although he could have suggested we engage him for some remediation work for which I apparently would have had no need, he was honest and talked me out of paying for something I did not need. Class act."

Mold Testing and Remediation questions, answered by experts

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

Certainly, DIY mold tests are not perfect when trying to determine whether you have a mold problem. They could give you a false positive reading, or they may fail to detect mold that’s behind a wall, especially if the infestation is still small. Ultimately, you should seek a mold inspection if the DIY test gives you a positive result, just to be certain. And if the test is inconclusive, it’s probably worth seeking an inspection from a pro.

Mold can grow anywhere in a home where moisture accumulates and doesn't dry out, particularly in areas with poor ventilation. Common materials affected include insulation and drywall. The most frequent locations for mold growth are attics, basements, crawl spaces, wall cavities, bathroom and kitchen walls, exposed foundations, windows and window sills, air conditioning and heating vents, and around fireplaces and chimneys.

Knowing what to expect during a mold inspection can help make the process easier. Prepare by closing doors and windows for 48 hours, turning off HVAC systems for at least two hours, and avoiding disinfectant chemicals for at least 48 hours. 

The mold inspection process takes between 24 and 48 hours. Your professional will check walls, fireplaces, air ducts, vents, and windows for visible spores. They will also take an outdoor base air sample. Your pro will send these samples to a lab for testing and advise you on the findings.

Slime mold can thrive for weeks or months in the perfect environment, but that rarely occurs. The mold will typically die within a week of you noticing it. However, it could be dead long before it disappears, and since it’s safe to handle, it’s easier to get rid of it all at once. This eliminates its chance to spread, and also won’t leave you looking at decaying slime mold.
