Inspecting Homes in Malibu
Malibu's coastal corridor has the highest year-round mean humidity in the LA basin — overnight RH often exceeds 90% even in summer — and direct salt air accelerates every HVAC and metal-corrosion failure mode an inspector checks for. The housing ranges from 1950s beach cottages (Point Dume, Big Rock) never built for permanent occupancy to 2010s hilltop builds with floor-to-ceiling glazing that condenses along window-frame interiors. Post-Woolsey-fire (2018) and Palisades-fire (2025) rebuilds add their own profile: framing that absorbed suppression water before reconstruction. A thorough inspection here pairs the structural, roof, deck, and electrical review with moisture mapping and mold, radon, and air-quality testing — because the salt-and-moisture load works on a house constantly.
What Our Inspectors Find in Malibu
Salt air, sustained high outdoor humidity, and a regional wildfire history make Malibu a place where hidden conditions are the rule. Owners keep meticulous visible interiors while the cavity behind a kitchen wall, the crawlspace under a deck, or the air-handler return quietly degrades. Many of our Malibu jobs start with a homeowner who was just allergy-tested and learned they are reacting to something they cannot see. A multi-discipline inspection — systems plus environmental testing — is the only reliable way to find it before it becomes a structural or health problem.

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.
