Mold Testing

Same-day and next-day appointments are usually available across our Sherman Oaks 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.

In many cases, yes — particularly in the 1960s and 1970s-era apartment stock that is common along the Sherman Oaks corridor. These buildings were constructed with plumbing systems, roofing materials, and waterproofing standards that have now exceeded their design life, and the shared infrastructure of multi-unit buildings means that a plumbing failure or roof intrusion in one location can spread moisture to multiple units before it is identified and repaired. Individual unit owners and tenants in these buildings have limited ability to control moisture conditions that originate in the building's common systems, and HOA or management company maintenance backlogs are a frequent contributing factor. Pre-purchase inspections in Sherman Oaks apartment conversions and condo buildings are particularly important for this reason.

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 Sherman Oaks fall within the standard industry range of $300 to $600, with a clear quote provided before any work begins.

Air sampling, swab testing, tape lift testing, wall cavity sampling, and HVAC mold testing. The inspector recommends the right method on-site based on what's found. Samples go to a state-certified lab, with results typically back in 24 to 72 hours.

Mold needs water to grow, so finding the moisture source is what prevents the same problem from coming back after any cleanup. Moisture detection during the inspection identifies plumbing leaks, roof leaks, condensation issues, and humidity buildup that's feeding any growth.

Yes. Post-remediation verification confirms the remediation contractor's work succeeded and the space is safe to reoccupy. Because we don't perform remediation ourselves, the verification stays independent of the remediation contractor's interests, which is what insurers and tenants look for.

No — inspection and testing only. We never perform mold removal or remediation. The company telling you how much mold you have shouldn't profit from removing it. What we provide is the diagnosis — extent of growth, moisture source, lab-confirmed species, and a written scope you can use to get accurate, comparable bids from multiple remediation contractors. In Sherman Oaks' older housing stock, where a superficial remediation treatment often masks a deeper moisture source at the plumbing or foundation level, that independent scope is what ensures the cleanup addresses the cause.

Commercial inspections along the Ventura Boulevard corridor follow the same instrument-based approach as residential work, scaled to the property's size and use type. For older retail and restaurant buildings, the inspection focuses on rooftop drainage, HVAC condensate management, and any below-grade mechanical or storage space. For converted residential-to-commercial properties, the original residential plumbing and structural details require the same assessment as a residential inspection. Reports are written for property managers, commercial tenants, and insurers with no remediation interest behind them.

Yes — landlord-tenant documentation is a regular part of our Sherman Oaks work. California's implied warranty of habitability requires landlords to maintain rental properties free of conditions that materially affect health. The inspection report either confirms the problem and defines the fix, or provides defensible evidence that the unit met habitability standards at the time of inspection. Because we perform no remediation, the report carries no financial interest — which makes it credible to LAHD inspectors and hearing officers as well as to both parties in a dispute.

Post-remediation verification confirms that a remediation contractor's work succeeded — affected material was removed, the moisture source was controlled, and indoor spore counts are back within normal range. In Sherman Oaks' older housing stock, where moisture sources are often building-system failures that have developed over decades, a remediation that didn't address the source will return within a season. Because 24H Mold Inspection never performs remediation, the verification carries no conflict of interest — the clearance report documents what we found rather than what a contractor needed us to find.
