Air Testing

Same-day and next-day appointments are usually available across our Simi Valley service area, with 24/7 emergency response for active leaks, recent water damage, or urgent real estate timelines. Standard scheduling runs 1 to 3 business days depending on availability.

Our certified mold inspectors assess bathrooms, kitchens, laundry rooms, basements, attics, crawl spaces, HVAC components, and any area showing signs of past or current water issues. Thermal imaging and moisture meters identify hidden moisture behind walls and under floors.

Yes — and it is one of the most common mold pathways we find in Simi Valley's 1970s and 1980s housing stock. The HVAC systems installed in homes from that era were sized and configured under different energy and moisture management standards than current equipment, and many have been in service for decades without the duct inspections or air handler assessments that would identify moisture accumulation. Forced-air systems in the Simi Valley climate — where summer temperatures drive heavy AC use and the indoor-outdoor temperature differential is significant — generate substantial condensation at the air handler and inside poorly insulated ductwork. When that condensation is not properly drained or when drain pans crack and fail, moisture accumulates in the air handler closet, inside wall cavities adjacent to ductwork, and in the building materials surrounding return-air chases. The result is mold growth that can be extensive by the time it becomes visible or produces a detectable odor.

Pricing varies based on the size of the property, the scope of testing required, and whether any lab work is included. Most residential mold inspections in Simi Valley fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.
