Immediate Safety Steps When You Suspect Mold

Take these actions after your call. Isolate the affected area by closing doors, and turn off your HVAC to prevent airborne spores from circulating. Don’t touch or disrupr the mold growth, as it can release dangerous particles and increases the complexity of professional mold remediation. Mold should not be touched and the affected area shouldn’t be entered. If anyone has respiratory concerns, move them to a clear area and wait for our assessment. Our Walnut Creek biohazard cleanup team will ensure a secure area and then identify what type of mold it is in order to conduct proper remediation procedures.

Types of Mold We Clean Up in San Francisco

Once the immediate needs are met, it’s good to know that the specific type of mold you have will not dictate our course of action. In San Francisco homes, we address all varieties of indoor mold in accordance with the ANSI/IICRC S520-2024 standard, which prioritizes physical removal over the use of biocides and chemicals. This standard governs the entire process, from a thorough assessment of the mold, establishment of control and contained areas, removal of the mold, advanced cleaning and restoration of the affected surfaces. Focusing on the physical removal of mold reduces the potential adverse health effects of employing unnecessary biocides and chemicals.

Once we have evaluated your mold issue, we will provide you an estimate and explain your financial options including insurance, to help facilitate the restoration process.
