Mold Inspection & Testing in West Hollywood
Mold and air quality testing for West Hollywood apartments, condos and duplexes, for tenants and owners alike.

What We Look For in West Hollywood
This is dense multi-unit territory, and that changes the question. In a shared building, the moisture source is often not in your unit. A slow leak in the unit above, a common wall riser, or a neighbour poorly venting a bathroom can all produce growth on your side of the drywall. Because so much of the housing here is 1920s to 1960s, bathroom exhaust often vents into the wall cavity or the attic rather than outside. We document conditions clearly enough to hand to a landlord, a property manager or a housing inspector, which is usually why tenants call us in the first place.
Apartments, Condos and Older Buildings in West Hollywood
Most West Hollywood residents live in apartments and condominiums, many in buildings constructed between the 1920s and the 1970s. In these buildings, one leaking shower pan, supply line or roof drain can affect several units, and the visible damage often shows up away from the actual source. Units on lower floors and those against hillside retaining walls near Sunset tend to hold more moisture. Bathrooms with no window and a weak exhaust fan are a frequent source of ceiling and grout growth. Many renters also want documentation they can share with building management. Our inspections look at the full picture: your unit, shared walls, the ceiling below a neighbor's bathroom and any history of leaks reported in the building, so the report points to the most likely cause.
Who We Help in West Hollywood
We work with homeowners, renters, landlords, property managers, real estate agents, buyers and sellers in West Hollywood. Some clients call after a leak or a musty smell, others need documentation for a landlord, an HOA or an insurance claim, and many book before closing on a home.

Mold Testing FAQs for West Hollywood
My neighbor's leak caused stains in my unit. Can you document it?
Yes. We document what we observe, take moisture readings and, when appropriate, collect samples. The written report gives you clear information to share with your landlord, HOA or the neighbor's insurer.
Do you work with HOAs and property managers in West Hollywood?
Yes. We inspect individual units and common areas for HOAs, property managers and building owners, and we can coordinate access with tenants.
Are you available at night or on weekends?
Our phone line is answered 24/7 at (818) 658-9336, and weekend appointments are available by request. After you book online, our team calls you within 2 hours to confirm.
Why does my bathroom ceiling keep growing mold?
In many older West Hollywood buildings, bathrooms have no window and an undersized exhaust fan, so steam condenses on the ceiling every day. A leak from the unit above can make it worse. We check moisture levels to tell the difference.
Can you inspect a unit before I sign a lease?
Yes. Some renters book an inspection before moving in, especially if they notice odors or staining during a showing. Coordinate access with the landlord or leasing office and we will schedule around it.
We Test. We Do Not Remediate.
Just Mold Testing is an independent inspection and testing company. We do not perform mold removal in West Hollywood 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.
