If you found mold in your home — whether it's on a bathroom wall, in your kid's room, or just a musty smell that won't go away — we'll come look at it for free. No pressure, no salesy quote. Just a real IICRC-certified mold tech who'll tell you what you're dealing with, what it'll take to fix it, and what your insurance will probably cover.
Mold spore exposure varies by species, concentration, and time. Some people have no reaction. Others — especially kids, elderly, asthmatics, and anyone immunocompromised — can be sensitive. Our IICRC S520 protocol includes containment, HEPA filtration, and post-clearance air testing so we can prove the mold is gone before we hand the property back.
Cough, wheezing, sinus congestion, asthma triggers. The most common reaction. Usually resolves quickly once the mold is removed.
Sneezing, runny nose, itchy eyes, skin rash. Most often in people with existing allergies, eczema, or sinus issues.
Higher sensitivity. Prolonged exposure can increase asthma risk in children. Always treat mold quickly when family includes infants, toddlers, or seniors.
HIV+, chemo patients, transplant recipients, autoimmune. Some Aspergillus species can cause serious infections. Special caution and faster remediation timelines recommended.
Removing the mold removes the risk. There's no documented safe long-term exposure level for most species — which is exactly why we don't cut corners on protocol. Source: CDC, EPA, Los Angeles County Department of Public Health.
Most LA mold remediation companies kill the mold and walk. The problem comes back within 6–12 months because the moisture source was never fixed. We're a CSLB Class B general contractor, so we trace the leak — slab, ceiling, plumbing, condensation — and fix it as part of the same project. Permanent solution, not a temporary one.
Pinhole leak in pressurized water lines under the foundation. Slow saturation under flooring causes mold growth in subfloor and wall cavities for weeks before visible signs appear. Requires leak detection + slab work.
Minor roof penetration or HVAC condensation drip soaks attic insulation and drywall. Mold growth begins in dark cavities within 48–72 hours. Spores spread through HVAC into living spaces.
Pipe joint failure inside a wall. Drywall absorbs water, mold colonizes, surface remains dry until staining appears. By then mold has spread 4–10× the visible area.
Inadequate ventilation, repeated steam exposure, caulking failure. Mold grows behind tile, under sinks, around windows. Most common bathroom mold and kitchen mold pattern in LA homes.
Burst pipe, flood damage, sewage backup that wasn't fully dried. Class 2/3 water events have measurable mold colonies within 72 hours if drying isn't completed to IICRC S500 standards.
High-moisture, low-ventilation areas with organic material. Crawl space mold and attic mold are common in LA hillside homes — often invisible until air-quality issues surface.
IICRC S520 is the federal standard for professional mold remediation. Insurance carriers, indoor air-quality professionals, and regulators all use it as the baseline for what counts as "done right." Each step produces documented evidence — air samples, photo logs, post-clearance testing — that the mold is actually gone.
Most homeowners think "black mold = toxic, everything else = not a big deal." Reality is more nuanced. Several common LA mold species cause health effects regardless of color. The remediation protocol is the same; the urgency varies. Lab testing is the only way to confirm species — but every mold growth on the property gets removed under IICRC S520 regardless.
Greenish-black, slimy. Grows on wet drywall, paper, fabric. Produces mycotoxins — the species behind most "toxic mold" headlines, but rarer than people think.
Where: Wet drywall, paper backing. Health risk: High.
Most common species in LA homes. Olive-green, gray, or brown. Triggers allergies and asthma. Found on damp surfaces, AC drip pans, and bathroom grout.
Where: HVAC, bathrooms, fabric. Health risk: Moderate (allergens).
Often appear together. White, gray, or green-blue. Found in HVAC, water-damaged wood, food. Some Aspergillus species cause aspergillosis — serious in immunocompromised patients.
Where: HVAC, wood, basements. Health risk: Moderate to High.
Mold coverage is the most confusing part of any restoration claim. Most standard homeowner's policies cover mold ONLY if it's a direct result of a covered water event — burst pipe, sudden leak. Long-term moisture damage from a slow leak or maintenance issue is typically excluded. We document every aspect of your case for the insurance claims process so the adjuster has everything needed for the broadest coverage.
Some policies have a mold sub-limit ($1k–$10k typical). California policies vary by carrier. We work with your insurance company directly to maximize coverage on every mold remediation claim — most clients pay only their deductible, never the full invoice.
Project timeline is driven by square footage of affected area, mold species, and rebuild scope. Below: realistic timelines we deliver against on residential and commercial mold remediation jobs.
Containment + removal + sanitization in 1–2 days. Common scope: bathroom mold, attic spot, single closet. Source repair adds 1–2 days.
Full S520 protocol with containment, multi-day HEPA filtration, post-clearance air testing. Source repair (slab leak, roof, plumbing) typically runs in parallel.
Multiple containment zones, structural material removal, HVAC mold remediation, full post-clearance protocol, then complete rebuild under our Class B GC license.
A mold-only specialist can run the IICRC S520 protocol — every certified remediator can. But most can't fix the slab leak, replace the roof drain, or rebuild the kitchen they just gutted. We're a CSLB Class B General Contractor. That changes everything about how a mold remediation project closes out.
