About Mold in West Hollywood
West Hollywood is unusually dense for the LA Westside — primarily 1920s-1950s small-lot single-family + duplex housing now packed in among 1970s-1990s mid-rise condominium and apartment buildings. The age mix is the issue: the 100-year-old single-families have original galvanized water-supply lines now well past service life, and the mid-rise condos have shared HVAC systems where a single corroded coil pan can contaminate three or four units' airspace. The Norma Triangle and Plummer Park neighborhoods have especially high concentrations of pre-1940 single-family stock with crawlspaces that flood routinely in heavy winter rain.
Why Mold Is a Problem in West Hollywood
Galvanized pipe corrosion is the dominant West Hollywood issue. Original 1920s plumbing in many homes has reached the point where pinhole leaks are accumulating faster than they can be repaired. Each one saturates the slab edge or wall cavity for weeks before discovery, and we are typically called in after the third or fourth visible-mold incident in the same wall cavity.

Types of Mold We Identify and Remove
We test for 19 mold species and spore categories — the same panel an AIHA-accredited environmental lab reports on every spore-trap. The six most common indoor species are shown first; expand the panel below to see every category we test for.

Black Mold
Stachybotrys chartarum
Often labeled "toxic black mold" — produces mycotoxins linked to respiratory irritation, chronic coughing, and worsened allergies in sensitive individuals. Removal should be done by certified, fully suited professionals.
- Where it's found
- Drywall, ceiling tiles, and wood that has stayed wet for 7+ days — typically after a roof leak, slab-leak, or hidden plumbing failure. Memnoniella, a closely related genus, is grouped with Stachybotrys on most lab reports.
- What it looks like
- Dark green-black, slimy or wet appearance when active.

Aspergillus
Aspergillus spp.
One of the most common indoor molds. Most species are harmless to healthy adults but can trigger asthma, sinus infections, or aspergillosis in immunocompromised individuals.
- Where it's found
- HVAC systems, damp insulation, food, leather, paper. Loves warm humid air — a near-constant concern in humid indoor environments.
- What it looks like
- Yellow, green, brown, or black powdery patches; often fuzzy at the edges.

Penicillium
Penicillium spp.
Common allergy trigger. Continuous exposure can worsen asthma and cause chronic sinus inflammation. Some species produce mycotoxins on water-damaged building materials.
- Where it's found
- Water-damaged carpets, wallpaper, mattresses, and fabric. Frequently appears within 24–48 hours of a leak.
- What it looks like
- Blue-green or grey powdery patches; smells musty.

Cladosporium
Cladosporium spp.
Triggers hay-fever-like symptoms, asthma flares, and skin rashes. Tolerates cool temperatures, so it can grow even in refrigerators and AC drip pans.
- Where it's found
- Bathrooms, kitchens, basements, HVAC drip pans, behind toilets, on shower grout.
- What it looks like
- Olive-green to black; velvety or suede-like texture.

Alternaria
Alternaria alternata
One of the most well-known asthma triggers — outdoor exposure is normal, but indoor growth concentrates spores and can drive severe respiratory reactions in sensitized people. Ulocladium, a visually similar genus, is grouped with Alternaria on most lab reports.
- Where it's found
- Window seals, shower stalls, around tubs, under sinks. Wherever condensation lingers.
- What it looks like
- Dark grey-green or brown; wool-like or velvety.

Chaetomium
Chaetomium globosum
A water-damage indicator species — its presence almost always means a hidden long-term moisture problem. Can produce mycotoxins; linked to allergic and neurological symptoms.
- Where it's found
- Behind drywall and under wood floors that experienced flooding or a sustained leak.
- What it looks like
- Starts white and cottony, then matures to grey, brown, or black.
