Inspecting Homes in West Hollywood
West Hollywood is unusually dense for the LA Westside — 1920s-1950s small-lot single-family and duplex housing packed in among 1970s-1990s mid-rise condos. The age mix drives the inspection: century-old single-families often have original galvanized water-supply lines and knob-and-tube remnants well past service life, while the mid-rise condos have shared HVAC where one corroded coil pan can affect several units' airspace. Norma Triangle and Plummer Park hold high concentrations of pre-1940 single-family stock with crawlspaces that flood in heavy winter rain, plus pervasive pre-1978 lead paint. A full inspection covers plumbing, electrical, structure, and shared HVAC alongside moisture, mold, and air-quality testing.
What Our Inspectors Find in West Hollywood
Galvanized-pipe corrosion is the dominant West Hollywood issue, and it rarely travels alone. Original 1920s plumbing in many homes now produces pinhole leaks faster than they can be repaired, each one wetting a slab edge or wall cavity for weeks before discovery, while aging electrical and shared condo systems add their own risk. A multi-system inspection that pairs a plumbing and electrical review with moisture and environmental testing catches the pattern early, instead of after the third or fourth visible incident in the same cavity.

Our Services
From initial inspection to complete remediation, we handle every step with physician-level care and precision.

Home & Commercial Inspection
A full visual inspection of the structure, roof, and systems — with a full-color, next-day report and clear next steps. Residential and commercial.

Mold, Radon & Lead Testing
Environmental testing for what you can’t see — mold, radon, lead, and indoor air quality — with lab analysis from an independent, accredited laboratory.

Remediation & Restoration
When something turns up, we handle it — mold removal and remediation plus water-damage restoration, with before/after documentation.
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.
