Ask an inspectorNo. Oso provides inspection and testing only. Because we do not sell remediation services, there is no conflict of interest attached to the findings.
A mold inspection is a structured visual and environmental assessment — looking for moisture sources, water intrusion, and conditions that support mold growth. Mold testing adds sampling — air, surface, or bulk samples analyzed by an independent laboratory — to clarify whether mold is present. Oso recommends testing only where it will change your next decision.
A qualified inspector identifies suspect materials — common in homes built before the 1980s, such as certain flooring, insulation, textured ceilings, and siding — then collects samples following established procedures. Samples go to an accredited laboratory for analysis. Because sampling disturbs the material, it should be done by a trained professional, consistent with EPA guidance.
Over-the-counter settled-plate kits can grow mold from normal background spores and rarely tell you where a problem is or what to do next. A professional inspection pairs visual assessment with targeted, lab-analyzed sampling so the findings point to a clear next step.
If your home was built before the 1980s and your project will disturb suspect materials — flooring, insulation, textured ceilings, roofing, or siding — testing first is the prudent step. Renovation and demolition rules treat confirmed asbestos-containing material differently, and testing before work begins keeps the project on the safer, compliant path.
Yes. Air sampling captures airborne spores for laboratory analysis and is often paired with an outdoor control sample for comparison. Air testing is most useful alongside a visual inspection — on its own, without context, airborne counts are hard to interpret. Oso will tell you honestly when air sampling will help and when it will not.
Timing depends on the property size, areas of concern, accessibility, and the type of inspection. Call with a few details about the property and Oso can explain what to expect.
Turnaround depends on the inspection and laboratory testing involved. Aaron will explain the expected timing when the scope is confirmed.
Property size, the number of areas evaluated, the number of laboratory samples, and lab turnaround options all shape the scope. Oso scopes each job by phone so you know exactly what is included before scheduling — call (949) 573-1937. Pricing is never published because every property is different.
Yes. Pre-purchase inspections, pre-listing evaluations, and testing for rental and commercial properties are a regular part of the work. Findings are documented independently of any remediation contractor, which keeps transactions and management decisions clean.
