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

Refrigerant leaks are extremely toxic and dangerous to your health. Not only can you face health risks, such as headaches, nausea, and dizziness, but there’s also the chance of death or loss of consciousness. In addition, refrigerant leaks are toxic to the environment, and they can cause permanent damage to the ozone layer and the earth’s atmosphere.

Black mold appears in areas with constant moisture and has a slightly fuzzy texture. It’ll have a primarily circular pattern. While it’s known to have a black color, it can also appear dark green, or dark brown, although a few types include orange or white flecks. Identifying black mold is important because people who inhale the spores could suffer respiratory issues or neurological problems. Black mold is a toxic material and requires a professional to remove it.

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.

Wood stain is not considered toxic after it dries. The solvents in wood stain are what give off volatile organic compounds (VOCs), which are toxic, but these dissolve as the product dries, leaving behind a non-toxic product. When working with wood stain, you should always wear a respirator and rubber gloves to protect yourself, but once it dries fully, it’s not toxic, according to the manufacturer’s instructions.

Bad odors and actual, visible mold aren’t the only ways to tell if your floorboards are suffering from too much moisture. Everything from high humidity to direct contact with water can cause wood to buckle, warp, peel, and discolor. Spotting one or more of these signs could be a clue that you’re dealing with mold.
