Mold Inspection & Testing in Granada Hills
Independent mold inspection and testing in Granada Hills, including the mid-century ranch homes of Balboa Highlands and Knollwood.

What We Look For in Granada Hills
Granada Hills is known for large lots and mid-century ranch homes built mostly in the 1950s and 1960s, including the Eichler homes of Balboa Highlands. Many of these houses still have original plumbing and older windows, and Eichlers have flat roofs and radiant heating pipes in the slab, so a leak can start above the ceiling or below the floor. The 1994 Northridge earthquake damaged many homes in the area, and some repairs from that time are now three decades old. We trace moisture before we sample.
Mid-Century Ranch Homes and Eichlers in Granada Hills
Granada Hills homes tend to be single-story with large yards, mature trees and pools. Flat-roof Eichler homes in Balboa Highlands have radiant heating pipes in the concrete slab, so a leak can start above the ceiling or below the floor. Older ranch homes often have original plumbing in the walls and under the slab. Mature trees drop leaves that clog gutters and roof drains. We inspect ceilings, walls near bathrooms and kitchens, floors for signs of slab leaks, window frames and the attic where there is one.

Mold Testing FAQs for Granada Hills
Do you inspect Eichler homes?
Yes. Eichlers need a different approach because many have no attic and use radiant heat in the slab. We check ceilings below the flat roof, walls, floors and window frames, and sample when it will help.
Our home has original plumbing from the 1960s. Should we test for mold?
Age alone is not a reason to test. If you have stains, a musty smell, a known leak or recent water damage, an inspection will tell you whether sampling is worthwhile.
Can clogged gutters lead to mold inside the house?
They can. Clogged gutters and roof drains can send water into walls and ceilings during storms. We look for staining near roof lines and check those areas with a moisture meter.
How much does a mold inspection cost in Granada Hills?
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.
How fast will I get results?
Lab results come back in 24 to 48 hours after sampling. We review them with you and explain what they mean.
We Test. We Do Not Remediate.
Just Mold Testing is an independent inspection and testing company. We do not perform mold removal in Granada Hills 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.
