Mold Inspection & Testing in Long Beach
Mold and air quality testing for Long Beach homes, historic-district properties and multi-unit buildings.

What We Look For in Long Beach
Long Beach has some of the oldest continuously occupied housing in the county, and the historic districts come with historic plumbing. Craftsman and Spanish revival homes here often still have original drain lines and basements or sub-floor crawl spaces that stay damp year round. Closer to the water, the combination of high humidity and older single-pane construction produces condensation problems that look like leaks but are not. In multi-unit buildings we see shared-wall and shared-riser issues. Identifying which of those three it is changes the repair completely, so we test before anyone guesses.
Historic Homes and Coastal Moisture in Long Beach
Long Beach has one of the most varied housing stocks in the region: Craftsman and Spanish homes in Bluff Park and Belmont Heights, historic districts like California Heights, beach cottages in Naples and Belmont Shore, postwar homes in Lakewood Village and large numbers of older apartment buildings closer to downtown. Many older homes sit on raised foundations with crawlspaces that collect moisture, and plumbing in these homes is often decades old. Neighborhoods near the water deal with marine humidity and, in low-lying areas, higher ground moisture. Older apartment buildings frequently have shared plumbing stacks and limited bathroom ventilation. We look at crawlspaces, under-sink areas, exterior walls and any spot with past water damage, and we explain whether air or surface sampling is the right next step.
Who We Help in Long Beach
We work with homeowners, renters, landlords, property managers, real estate agents, buyers and sellers in Long Beach. 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. Whatever the reason, you get an independent inspector, honest answers and a clear written report.

Mold Testing FAQs for Long Beach
Do older Long Beach homes have more mold problems?
Not always, but older plumbing, raised foundations and decades of remodels create more places for slow leaks. A moisture-focused inspection helps find problems before they spread.
Do you inspect apartment buildings in Long Beach?
Yes. We inspect individual units for tenants and owners and work with property managers on multi-unit buildings, including common areas and shared plumbing walls.
Is there a rush option for lab results?
Yes. Standard results typically arrive in 24 to 48 hours, and rush lab options are available when you need answers faster, such as during escrow.
Do you serve Naples, Belmont Shore and Bixby Knolls?
Yes. We serve neighborhoods throughout Long Beach, including Naples, Belmont Shore, Belmont Heights, Bluff Park, Bixby Knolls, California Heights, Los Altos and downtown.
Can a musty crawlspace affect the air in my home?
It can. Air from a damp crawlspace can move into living areas through gaps in the floor and around plumbing. We inspect accessible crawlspaces and can use air sampling when odor is the main concern.
We Test. We Do Not Remediate.
Just Mold Testing is an independent inspection and testing company. We do not perform mold removal in Long Beach 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.
