Mold Inspection & Testing in Oak Park
Independent mold inspection and testing in Oak Park, from the original neighborhoods along Medea Creek to newer hillside homes.

What We Look For in Oak Park
Oak Park is a planned community in Ventura County, built mostly in the 1970s and 1980s along Medea Creek and the surrounding hills. Many homes are two stories with bathrooms over finished ceilings, attic air handlers and slab foundations. Aging shower pans, original windows and irrigated slopes right behind the house are the moisture sources we check most often here. We find the source before we sample.
Two-Story Homes and Irrigated Slopes in Oak Park
Oak Park is an unincorporated community in Ventura County between Agoura Hills and Thousand Oaks. Many streets are lined with two-story homes on sloped lots, often with irrigated hillsides directly behind the house. When sprinklers overspray or slope drains clog, water can collect against stucco and soak the bottom of walls. Inside, upstairs bathrooms and laundry rooms are frequent sources of ceiling stains. We check exterior walls on the uphill side, baseboards, ceilings under bathrooms, attics and the area around the water heater.

Mold Testing FAQs for Oak Park
Is Oak Park in your service area even though it is in Ventura County?
Yes. Oak Park is close to our West Hills base, and we serve it along with Agoura Hills, Westlake Village and Thousand Oaks.
A water stain appeared on our ceiling under an upstairs bathroom. Does that mean mold?
Not necessarily. A stain shows that water reached the ceiling, but growth depends on how long the material stayed wet. We measure moisture, look at the area and sample if the source or extent is not clear.
Can sprinklers cause mold inside the house?
They can. Overspray against stucco or clogged drains on a slope can keep the base of an exterior wall wet, and over time moisture can wick into framing and drywall. We check moisture along exterior walls from inside the house.
How much does a mold inspection cost in Oak Park?
The professional mold inspection is $49, and it is waived if you proceed with testing during the visit. Testing is priced and approved by you before any samples are taken.
Will you tell me if I do not need testing?
Yes. After the inspection we only recommend testing when it will answer a real question. If there is no reason to sample, you have paid $49 for peace of mind.
We Test. We Do Not Remediate.
Just Mold Testing is an independent inspection and testing company. We do not perform mold removal in Oak Park or anywhere else, and we never will. The company that finds the mold should not be the company that profits from removing it.
You get a written report with the laboratory data, an explanation of what the numbers mean, and practical next steps. If remediation is needed we tell you exactly what to ask a contractor for, then we are happy to return afterwards for independent post-remediation verification.
