Mold testing in Los Angeles ranges from $300 to $900 depending on the company and number of samples. Here’s a transparent breakdown of what you’re paying for — and what’s not worth it.
Many homeowners confuse mold testing with mold inspection — they’re different services that answer different questions. Here’s when you need each one.
Mold inside ductwork spreads spores through every room every time your HVAC runs. Small patches on hard-surface ducts can sometimes be cleaned — but flex duct, insulation, and large infestations must be removed and replaced. This Los Angeles guide covers the warning signs, the safe cleaning process, and when duct mold is a symptom of a larger moisture problem that needs professional remediation. IICRC-certified: (818) 336-1800.
Mold remediation is dangerous when moldy materials are disturbed without containment — stirring up spores and spreading contamination to clean areas. Done by a certified contractor with proper PPE, HEPA filtration, and negative air pressure, the process is designed to be safe. This LA guide explains the real risks, what proper protocols look like, and how to spot a contractor cutting corners. IICRC-certified: (818) 336-1800.
Vinegar kills some surface mold on tile and glass, but doesn’t penetrate porous materials like drywall, wood framing, or carpet — and does nothing to address the moisture source. This LA guide explains what vinegar actually does (and doesn’t do), which household products work on which surfaces, and when mold coverage signals a problem that needs professional remediation. IICRC-certified, free assessment: (818) 336-1800.
A certified mold inspector uses moisture meters, borescopes, air sampling, and surface testing to identify the type, location, and source of mold — producing documentation your insurer and remediation contractor can act on. This LA guide explains what credentials to verify, what a real inspection includes, and the difference between an independent inspector and a contractor who inspects and remediates. Free assessment: (818) 336-1800.
The most common basement molds in LA homes are Aspergillus, Penicillium, Cladosporium, and Stachybotrys — but the species matters less than addressing the moisture source keeping it alive. Basements should stay below 50% humidity. This guide covers how to identify each mold type visually, which carry the highest health risk, and when basement mold signals water intrusion needing professional remediation. IICRC-certified: (818) 336-1800.
White fluffy mold is active, rapidly spreading fungal growth visible during sporulation — when mold releases airborne spores. Some species show fuzzy growth within 24–48 hours in humid conditions. This Los Angeles guide covers the most common white mold types found in homes, the health risks, how to identify them visually, and when white mold on wood, drywall, or in a crawl space requires professional remediation. IICRC-certified: (818) 336-1800.
Can black mold cause pneumonia? While it doesn’t directly cause bacterial pneumonia in healthy people, it can trigger hypersensitivity pneumonitis — an inflammatory lung disease with identical symptoms. Learn the medical facts, who’s most at risk, and when to call for professional mold remediation in Los Angeles.
White, fuzzy growth on attic wood isn’t cosmetic — it’s a sign of active moisture damaging structural framing. Attic mold spreads quickly in warm, poorly ventilated spaces and is often caused by bathroom exhaust fans venting into the attic or roof deck leaks. This LA guide covers how to identify it, why it grows, what remediation involves, and typical cost ranges. IICRC-certified mold remediation: (818) 336-1800.
Black mold in LA homes rarely starts with a dramatic stain — it starts with a smell, damp air, or paint lifting near a window. The cause is almost always an unresolved moisture source: a hidden leak, persistent condensation, or inadequate ventilation. This guide explains the specific conditions that allow Stachybotrys to grow, the most common sources in LA homes, and what professional remediation requires. IICRC-certified: (818) 336-1800.
A musty smell in a Los Angeles basement is almost always mold — growing on drywall, framing, or concrete after seasonal rain, a slow plumbing leak, or condensation on cold pipes. This guide covers how professional basement mold removal works, what IICRC S520 protocol requires, the difference between surface cleaning and true remediation, and typical costs in LA. IICRC-certified, free on-site assessment: (818) 336-1800.
Residential mold in Los Angeles most often starts with a smell — after rain, near a window, or in a bathroom with chronic moisture. By the time it’s visible, growth has often spread behind drywall or into framing. This guide covers the full professional mold removal process, how IICRC S520 protocol works, the difference between surface cleaning and true remediation, and what to expect from a free assessment. Call (818) 336-1800.
Water damage and mold are the same problem at different stages — wherever moisture persists for 24–48 hours, mold follows. Treating them separately leaves the underlying issue unresolved. This Los Angeles guide covers the combined remediation process: water classification, structural drying, mold testing, containment, removal, and clearance — plus how insurance claims work when both are present. IICRC-certified: (818) 336-1800.
Black mold symptoms appear two ways: structural signs in your home (dark spots, musty odors, warping near moisture sources) and health symptoms in your household (persistent cough, nasal irritation, worsening asthma). In LA, where hidden moisture is common after rain, both can develop before mold is visible. This guide covers what to look for, health risks by exposure level, and how professional remediation works. IICRC-certified: (818) 336-1800.
That musty smell after a minor leak is often the first sign of mold growing inside walls, under flooring, or in HVAC ductwork — and health risks escalate with exposure time. In Los Angeles, leaks from rainfall, plumbing, and condensation are common, making early action critical. This guide covers health risks by exposure level, who is most vulnerable, and the professional remediation process. IICRC-certified, free assessment: (818) 336-1800.
A mold inspection in Los Angeles requires checking more than visible surfaces — moisture migrates behind drywall, under flooring, and into HVAC systems. This step-by-step checklist covers what a certified inspector examines in each room, the instruments used (moisture meters, borescopes, air samplers), how to read a mold report, and the difference between an inspection-only and a test-and-remediate engagement. IICRC-certified: (818) 336-1800.
Wet drywall has a 24–48 hour window before mold begins growing inside the paper facing and behind the gypsum. Surface fans aren’t enough — moisture trapped inside the wall cavity requires dehumidifiers and air movers sized to the space. This LA guide covers how to assess drywall saturation, when it can be dried vs. must be removed, and the professional drying process IICRC contractors use. Free inspection: (818) 336-1800.
The best way to clean mold starts with assessment, not a scrub brush. Small patches on non-porous surfaces can sometimes be cleaned safely. But mold on drywall, wood framing, or anything behind a wall is a remediation job — not a cleaning job. This LA guide covers what you can safely DIY, what requires professional remediation, the EPA-recommended approach for each surface, and how to verify the job is done correctly. Call (818) 336-1800.
Bathroom mold grows where moisture can’t escape — behind tiles with failing grout, in drywall behind the tub surround, and in exhaust fans that vent into the attic. Surface cleaning keeps things looking clean without addressing the moisture source. This LA guide covers the ventilation standards, materials, and maintenance schedule that actually prevent mold — plus when bathroom mold signals a structural moisture problem needing professional assessment. Call (818) 336-1800.
