Post-Wildfire Smoke Cleaning in Los Angeles

Why LA wildfire-smoke remediation requires a specific protocol

LA fires are different from suburban or rural fires elsewhere. Three reasons matter for cleaning. First, Santa Ana wind pattern: fires that start in the canyons (Eaton, Bobcat, Getty, Palisades, Saddleridge — the recent ones we have all watched) are pushed by 30–60 mph offshore winds across the LA Basin. That means homes 15, 20, even 30 miles from the actual burn area still get measurable soot and PM2.5 deposition because the smoke plume is wide and low-altitude. Second, urban-interface burning: when wildfires hit suburbs they burn cars, plastics, treated wood, paint, electronics — not just brush. The smoke contains heavier particulates and a different chemical profile than pure brush smoke. Third, LA home construction: most LA homes have older window seals, single-pane windows in many neighborhoods, and HVAC systems without HEPA-grade filtration. Smoke gets in, settles on every surface, and accumulates inside ducts and on filter housings.

What that means for cleaning: a regular deep clean is not enough. Standard cleaning products do not remove fine PM2.5 particulates from soft surfaces — they smear them. Vacuuming with a non-HEPA vacuum recirculates the particulates back into the air. Damp-wiping without proper microfiber technique pushes soot into surface pores. The protocol matters as much as the effort. And the order matters: HEPA-vacuum soft surfaces first (so suspended particulates are removed), then dry-soot-sponge pre-treat any visible smoke staining on hard surfaces, then damp-microfiber wipe everything in a top-to-bottom sequence (so anything we knock down lands on uncleaned surfaces, not freshly-cleaned ones).

We have been doing this work in LA since the 2018 Woolsey fire and we have refined the protocol across every major event since. We carry HEPA-rated vacuums on every truck (consumer vacuums do not capture PM2.5), color-coded microfiber rotation (so soot does not transfer between surfaces), dry soot sponges (a specific natural-rubber product that lifts soot dry without smearing), and pH-neutral surface cleaners that do not react with soot residue. Our crew leads have worked through the Bobcat, Saddleridge, and Palisades response cycles and know what to look for in homes that were 5 miles from the burn versus 20 miles from the burn — different scopes apply.

What we do, in the order we do it (the protocol matters)

Step 1: assessment. When we arrive we do a 10-minute walkthrough with a flashlight and a white microfiber cloth. We check window sills, top of door frames, top of fan blades, top of fridge — the horizontal surfaces above eye level where soot settles invisibly. We test surfaces with the white cloth (any gray transfer means soot present). We note which rooms have higher exposure (typically rooms with windows facing the wind direction during the fire) and which have lower exposure. This determines crew assignment for the rest of the visit.

Step 2: HEPA-vacuum soft surfaces. Every rug, every sofa cushion, every drape, every mattress, every fabric chair. This is done before any wet cleaning anywhere because vacuuming will kick particulates into the air and we want them captured before we wet anything down. We use commercial HEPA vacuums (HEPA H13 minimum) with sealed body construction so nothing leaks. Drapes are vacuumed top to bottom; if heavy soot is present they are taken down for off-site cleaning at a separate scope.

Step 3: dry soot sponge on hard surfaces. Any visible smoke staining on walls, ceilings, or trim gets a pass with a natural-rubber soot sponge — dry, no liquid. This lifts the soot off in chunks rather than smearing it. We do this before any wet cleaning because adding water to soot makes it harder to remove. We do not repaint or do drywall work; if walls have permanent smoke staining we document and recommend a separate painting service.

Step 4: damp-microfiber wipe, top to bottom, room to room. Color-coded microfiber so kitchen / bathroom / general / glass do not cross-contaminate. Top of door frames, light fixtures, fan blades, picture frames, shelves — every horizontal surface. Then walls (spot-clean, not full wash). Then counters, vanities, window sills. Then floors mopped with low-residue solution. We work from cleanest area to dirtiest, top to bottom, so anything we miss falls onto a surface we have not yet cleaned.

Step 5: HVAC-side cleanup (visible parts only). Vent registers (the louvers in the ceiling or wall) HEPA-vacuumed and wiped. Return-air grilles same. Ceiling fans disassembled and blades washed. AC filter assessment: we look at the filter, photograph it, and recommend replacement timing — the actual filter swap is yours to do or schedule with HVAC. We do not service ducts, coils, or blower internals — that requires a duct-cleaning specialist with negative-pressure equipment, and we refer for that.

Step 6: documentation. Before-and-after photos of every major room, plus close-ups of any heavy-soot zones. Itemized scope of work. Receipt formatted for insurance submission. Smell-test note: post-clean smoke odor assessment. If smell persists at 24 hours, we offer a complimentary recheck.

Insurance claim documentation — what we provide

Every LA homeowners policy handles wildfire smoke differently. Some pay for full cleaning under loss-of-use; some require itemized smoke-damage proof; some pay for HEPA professional cleaning specifically. We provide the documentation that supports the most common claim patterns: dated, geo-tagged photos before our work begins; itemized scope of services; receipt with line-item pricing; smell-test note; and recommendation for any further professional services (HVAC duct cleaning, painting, drape off-site cleaning).

We have submitted documentation to most major LA-area insurers — State Farm, Allstate, Farmers, Mercury, Wawanesa, AAA, Liberty Mutual — and we know what their adjusters typically need. If your insurance requires a specific format or additional documentation, tell us at booking and we will provide it. We do not negotiate with your insurance directly — that is your role or your public adjuster's — but we make the claim filing as straightforward as possible.

If your home has heavier smoke damage that requires structural intervention (drywall replacement, repainting, full carpet replacement, full HVAC duct cleaning), we will tell you honestly. Our scope ends where your scope of work expands — we will not oversell you on services that exceed our trade. We have a referral list of LA-area smoke-damage contractors we trust if you need them.

What we do not do — and what to schedule alongside

We do not do HVAC duct cleaning. That requires negative-pressure equipment and a different licensure. We assess and recommend; you book a duct-cleaning specialist separately. The right sequence is: HVAC duct cleaning first, then our surface remediation, so the duct cleaning's stirred-up dust settles on surfaces we are about to clean.

We do not do painting or drywall. Smoke-stained walls that do not respond to dry-soot sponge and damp wipe need a coat of stain-blocking primer and paint. That is a painter's job. We document and refer.

We do not do drape, curtain, or large-area carpet off-site cleaning. Heavy-smoke drapes go to a textile cleaner. Wall-to-wall carpet with heavy smoke gets a professional carpet cleaner with hot-water extraction and odor-neutralization. We can refer trusted vendors.

We do not do air-duct testing or air-quality lab work. If you want lab-grade air-quality testing post-clean, schedule an indoor air-quality consultant separately. We do qualitative smell-test and visible-residue check, not lab-grade analysis.

Wildfire-season prevention and ongoing maintenance

If you are in a high-risk LA neighborhood (anywhere in the canyons, hillsides, or wildland-urban interface), you should have a fire-season cleaning plan in place before fire season arrives. This means biweekly or monthly maintenance through fire season (typically September through December in LA), upgraded HVAC filtration (MERV 13 or HEPA at minimum during fire season), sealed window and door gaskets, and a portable HEPA air scrubber in primary bedrooms.

We offer a fire-season retainer plan that holds you a reserve cleaning slot for the duration of fire season. If a major event affects your area, we can be at your home within 5–10 days even when our regular schedule is overwhelmed. The retainer is $290 for the season and is credited against any cleaning visit you book. Most clients in Pacific Palisades, Brentwood, Bel Air, La Cañada Flintridge, and parts of Pasadena and Sherman Oaks book this every year.

On the household side: keep an N95 or KN95 mask supply for everyone in the home during fire season, run AC on recirculate (not fresh-air intake) during smoke events, close windows and doors at the first AQI alert, and have a clean route to your safe room (typically a bedroom with the best window seal and the least exterior wall surface). These are not cleaning services but they reduce how much smoke ends up in your home before our crew arrives.
