"I worked with Robert, who gave me a thorough inspection with a comprehensive explanation of the whole inspection process. He even followed up when I had a roof leak issue after my inspection to see if any further testing was needed. I appreciate the time and care Bye Bye Mold gave in addressing concerns I had and giving me peace of mind."

"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 FAQs, answered by experts

When used in the correct quantity and with the right procedures, boric acid will produce fumes with limited to no toxicity. You’re more likely to experience adverse side effects from boric acid toxicity by accidentally ingesting it or touching it with bare skin. All the same, wearing an air-filtering mask is a good way to keep even minorly toxic fumes out of your system. Don’t forget gloves, too!

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.

While goats can eat poison ivy and other plants that are harmful to humans, this doesn’t mean they can eat anything. Certain plant species, like azaleas, sumac, nightshade, Virginia creeper, and more, can kill goats. If your property has any of these plants, it won’t qualify for goat rental services. Most rental companies will ask for pictures or videos of your property or even inspect your land themselves to ensure none of these plants are present.

Yes, if there is mold in your drywall mud and you then use it to build walls in your house—or if mold develops in your set drywall, like it can in hot and humid areas—it can lead to illness. Mold in your drywall (or other parts of your home) can make existing respiratory conditions or allergies worse, and the effect can be more intense for those who have existing health issues or compromised immune systems.

Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and  contact your gas company.
