"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."

"I definitely recommend Santa Clarita Mold Inspection! I needed a mold inspection and was genuinely impressed with the company from start to finish. They were transparent throughout the entire process, and Nick was thorough, professional, and knowledgeable. Since this was my first time needing these services, I especially appreciated that Nick took the time to explain each step of the inspection process and what I could expect after the testing was completed. I was also extremely impressed with the final report and the level of detail that went into preparing it. The professionalism and thoroughness of the report were incredibly helpful and allowed me to utilize the documentation for legal purposes. Thank you so much to Santa Clarita Mold Inspection, and especially to Nick, for your time, effort, and professionalism. I truly appreciate the quality of service I received and would absolutely use your company again if the need arises. Trustworthy, I highly recommended!"

"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

Mold is very likely if you do not take action to fully dry your home within around 24 to 48 hours after water damage occurs. This can happen even faster in warm, dark locations with extensive water damage. In areas of the home that receive ample sunlight and only have slight moisture issues, it can take weeks for mold to appear.

Yes, mold under silicone caulk can potentially cause health issues, which may be more noticeable in people with asthma, allergies, or other respiratory conditions. Mold releases spores into the air, and inhaling these spores can cause symptoms such as coughing, sneezing, eye irritation, and skin rashes. It's important to address mold issues promptly to protect your health.

Pellet stoves burn compressed wood byproducts, making them very efficient and clean-burning. However, even efficient combustion still produces fine dust particles, which could have an effect on the health of vulnerable people in your household, such as infants and people with asthma. A wood stove pro can help determine whether the levels in your home are unsafe.

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. 

Black mold often smells musty, stale, or earthy, and some people liken its scent to that of sweaty clothing. While not everyone can identify the smell of mold, you are likely to smell it before you see it, as it usually is hidden in dark, damp areas; instead, the scent may pervade your entire home. If you smell mold, start by opening windows and looking for the source of the smell. If you find mold or are concerned about side effects, call a mold specialist right away, as it can be almost impossible to get rid of yourself.
