Do you smell musty and damp odors in your home or office? These are clear signs of property contamination. These micro-organisms thrive in wet, damp environments, usually caused by a water leak or condensation. They produce damaging toxins that can exacerbate asthma, instigate allergic reactions, and cause deadly lung infections. While it can be visible on the surface, they can also travel by air. **You must provide parking in the San Francisco area**

"It went very well. He had to come back 3 times to make sure the mold was gone since it was done by another company. We wouldn't have known that otherwise."

Golden State Inspection Services, LLC is a service oriented, multi-inspector firm. We conduct buyer home inspections, seller home inspections and commercial property inspections, mold testing, infrared scanning and comprehensive energy audits. Golden State Inspection services conducts inspections throughout northern California.

"Summary: Zero communication after the inspection. I hate to leave a negative review but I believe this must be done given my experience. I had an inspector come by on 2/26 for pest control. He was considerate and thorough (the only reason I am giving two stars instead of just one), and he told me I would receive the complete quote on the following Monday. Well, that did not happen. After waiting on the quote for a whole week, I called the company on 3/5 and let them know that I didn't receive my quote. They said they would look into my case and call me back right away. Well, that did not happen either. So on 3/9, I called the company again to inquire on the status of my quote (I actually had to help them backtrack to find my record!). I was told that they would contact the inspector who came to my house and call me back ASAP. Well, today is 3/20 and I haven't heard back yet. I am giving up."

Mold Testing and Remediation questions, answered by experts

Mold and mildew are always a primary risk with any water damage, but it’s not guaranteed that mold will grow. The chances of mold growth are dependent on many factors, such as the severity of the damage and how quickly the area was cleaned up and dried out—that’s why responding to water damage immediately is imperative. If you suspect you have mold and mildew growth, you should talk to a local mold removal expert .

Removing mold yourself can be dangerous. Always wear protective gear to cover your skin, face, and eyes, and wear a respiratory mask to protect your lungs. It is most recommended to only remove small areas of mold on your own and leave large mold growth to professionals. Mold growth can also be persistent. Without addressing the root cause, DIY surface cleaning can be ineffective and temporary.

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

Many caulk alternatives are safe for use in kitchens and food preparation areas, provided you apply them correctly and let them cure for the right amount of time. If you’re unsure about this step, call in a pro to do it for you. Silicone putty and caulk strips are often used around sinks and countertops due to their waterproof and flexible nature. Always choose products labeled as safe for kitchen use and follow the manufacturer's instructions for proper application and curing.

Just because you find mold in your home does not mean you need to pursue professional remediation services. You can often clean small amounts of surface mold, such as in bathrooms or on windowsills, using household products. However, extensive mold growth, persistent odors, or mold caused by water damage require professional remediation. A good rule of thumb is to hire a pro when the mold is in an area larger than 10 square feet, poses health risks, or affects the structural integrity of your home.
