The short answer
Right now: Stay out until the fire department says the building is safe to enter. Soot and smoke residue are respiratory hazards, so keep children and anyone with asthma out. Leave the power and gas off until they are checked, and photograph everything before it is moved.
Fire and smoke restoration is three jobs: drying the water used to fight the fire, removing soot whose chemistry depends on what burned, and removing odor held in cavities and ducts. IICRC S700 is the industry standard. Structure and contents are separate scopes, and ACV or RCV coverage decides how belongings are paid.
What should you know before anyone starts cleaning?
What burned decides whether the residue is dry and powdery, greasy and smeared, or acidic. That decides the method, and the wrong method can set it into the surface.
It follows air through wall cavities, ductwork and anything porous, so rooms that look untouched can belong in the scope.
It needs the same drying goal and daily readings as any structural drying job.
Ask for two documents. Contents restoration has its own inventory and its own part of the claim.
Is the damage bigger than the burned room?
Fire damage is easy to under-scope at first glance, because much of it sits where there were no flames.
Odor follows air paths, and air paths run through the whole house.
The system can carry residue to every room it serves.
Wipe one with a dry white cloth. A gray smear means residue is there.
Or it is standing in the basement, or has soaked ceilings and insulation.
Some residues keep acting on materials for as long as they sit.
Weather has been getting in since the fire. That calls for board-up and tarping first.
What should be assessed before a scope is written?
Half of this list is about rooms where nothing burned.
Whether the fire department has released the building, and whether power and gas need checking before work starts.
It decides the residue type, and so the cleaning method.
Including surfaces that look clean and the cavities behind them.
Whether it ran, and the state of the ducts, filters and equipment.
How much, where it went, and whether drying has started. It is a full water loss in its own right.
Broken windows and cut vents to cover now, and in older houses, materials to test for lead or asbestos before removal.
How is a fire loss worked, in order?
The order matters: securing and documenting come before any cleaning, and the rebuild comes last.
Board up and tarp every opening the fire and the firefighters made. Until that is done, weather and access keep adding to the loss.
Photos and video of every room, item and surface, including your own set. A contents claim rests on what was recorded before cleanup began.
Extraction and drying to a measured goal, with daily readings, exactly as in any water loss. Left alone, firefighting water can add a mold problem to a fire one.
Early cleaning of metals, electronics and delicate finishes, which keep deteriorating while acidic residue sits on them.
Charred material, heavily soiled porous items and burned insulation come out. Removal also shows where the damage really ends.
The method matched to the residue, dry before wet, HEPA vacuuming throughout, starting with the gentlest method that works.
Ducts, equipment and filters, where the system ran. A clean house on a dirty system dirties itself again the first time the heat comes on.
Take out or seal the material holding it, open cavities where residue is trapped, then finish with air treatment. Air treatment is the finishing step, not the fix.
Seal sound surfaces where residue cannot all come off, then move to reconstruction: a separate scope, priced separately, where you have time to compare bids.
Why does the type of soot change the cleaning method?
Technicians classify residue because the right method for one type is the wrong method for another. Scrubbing a greasy residue, or wetting a dry one, can drive it into the surface for good.
| Residue | Where it comes from and how it is cleaned |
|---|---|
| Dry smoke residue | From a fast, hot fire burning mostly paper and wood. Powdery and loose, and it can come off with dry chemical sponges and HEPA vacuuming before anything wet is used. |
| Wet smoke residue | From a slow, smoldering fire, and from burning plastics and rubber. Sticky, smeary and strong-smelling. Dry methods do little, and it needs solvents and more labor. |
| Protein residue | From cooking fires where food burned. A thin, nearly invisible film that yellows finishes, with an odor far stronger than anything you can see. Easy to miss on cabinet interiors and ceilings. |
| Fuel-oil soot | From an oil furnace puff-back. Oily, and spread through the house by the system that made it, as far as the ductwork reaches. |
| Acidic residue | Some burning plastics and synthetics leave residue that keeps etching metal, glass and finishes while it sits. This is why early cleaning protects value before any rebuild decision. |
A technician should be able to tell you which residue this is and which method it calls for. It is a fair question on day one.
What belongs in the written scope
Ask for these in writing before the equipment arrives. A scope that is only spoken cannot be checked later.
Which residue is where, and which cleaning method each area gets.
Which rooms and cavities are in the odor scope, and how that line was drawn.
A list of materials removed, and which surfaces get a sealer instead of full cleaning, with the reason.
The target readings and a daily moisture log, as for any water loss.
Whether duct and equipment cleaning is included, and if not, why not.
What is cleaned on site, what is packed out, and the list of items called non-salvageable.
What is unsafe in a house after a fire?
The fire being out does not make the building safe. These are the hazards to know before you or anyone else goes in.
Burned framing, floors and ceilings can fail. The fire department decides when you can enter.
A respiratory hazard. Keep children and anyone with asthma or a heart or lung condition out, and do not stir it up by sweeping.
Leave them off until the utility or a licensed electrician has checked them.
In a house built before 1978, burned or removed paint can contain lead, and older ceilings, flooring and insulation can contain asbestos. Test before tear-out.
Ozone is a lung irritant. Treated rooms stay empty of people, pets and plants until the crew clears them.

What moves the price
A fire loss arrives as several invoices: securing, water mitigation, structural cleaning, contents and reconstruction. Each has its own logic, and each should be readable on its own.
| Factor | Why it changes the number |
|---|---|
| Board-up and tarping | The first invoice, priced by the number and size of openings. |
| Residue type | Wet smoke and protein residue take far more labor per square foot than dry residue, on the same visible damage. |
| Area of residue and odor | Larger than the burned area on many losses, and the reason an early estimate grows. |
| Water mitigation | A full drying scope, with its own equipment-days, inside the fire claim. |
| Contents | How many items, how many are packed out, and how many need specialist cleaning. Pack-out adds transport, storage and return. |
| HVAC and odor work | Duct cleaning where the system ran, plus the removal and cavity work behind real odor control. The air treatment at the end is the small part. |
| Reconstruction | Priced like any construction job, and driven by whether the finishes can be matched. |
HyreRestore publishes no average price for this work. Category of loss, affected area, how long equipment runs and local rebuild costs move the number far enough that a single figure would mislead.
How does a fire claim treat this work?
This is how the standard homeowners forms are built, not what your policy says. Your declarations page and your state decide the real answer.
| Question | How the claim treats it |
|---|---|
| Is fire covered? | Fire is one of the perils the standard homeowners forms, including the HO-3, are built around. Check your declarations page for limits and exclusions. |
| Is firefighting damage part of it? | Water used to put out a covered fire, roof vents cut for ventilation and doors forced for access are generally handled as part of the fire loss. |
| What about smoke in rooms that did not burn? | Smoke and soot damage can be claimed beyond the burned room. That is why the scope should cover the whole house. |
| How are belongings paid? | Contents have their own limit and inventory. With actual cash value (ACV) you are paid less depreciation; with replacement cost (RCV) you can recover the depreciation once you replace. See ACV or replacement cost. |
| Where do I stay? | Loss-of-use coverage (additional living expenses) can pay the extra cost of living elsewhere while the house is unlivable. The Insurance Information Institute says to keep receipts and records of all of it. |
| What if more damage turns up? | Damage found once cleaning opens surfaces is sent to the adjuster as a supplement, with photos and readings. |
| Why is the insurer investigating? | An insurer may look into how the fire started before settling. Leave the scene as asked, and keep your own photos. |
Coverage is decided by your own policy and the peril, not by what is typical. Read the declarations page, and where the answer matters, put the question to your insurer in writing.
One question separates real odor work from a fragrance.
“What are you removing, and where is the odor coming from?” Not which machine, and not which product. Smoke odor lives in porous materials, cavities and ducts.
A company that answers by naming the materials coming out and the cavities being opened is doing the job. One that answers with a product name is covering the smell for a few weeks.
What to ask before you sign
And which cleaning method does it call for?
How did you decide where it stops?
As opposed to treating or covering it.
Can I see both in writing?
If the system ran, why or why not?
And will I see the daily moisture log?
Will I get the list with photos before anything is thrown out?
What exactly am I signing today?
What to have ready
Before any cleaning, including rooms that look fine.
From the fire department that responded, once it is available.
Plus the adjuster’s name and contact details.
Start it before anything leaves the house, with the contents inventory builder.
Hotel, clothing, meals and essentials.
Photos, documents and heirlooms you want saved first.
Where this goes wrong
Handling soot presses it into surfaces and can turn a cleanable item into a replaced one. It also removes the evidence for that part of the claim. Photograph first, and leave residue to a crew with the right method.
The Insurance Information Institute says to avoid throwing out damaged items until the adjuster has visited. Photograph, list and keep everything until then, or until you are released in writing.
Suppression water is a full water loss: extraction, a drying goal and daily readings. If it is skipped while everyone focuses on soot, the fire claim can turn into a mold claim.
Ozone, hydroxyl and thermal fogging have a place at the end of a job done properly. Used instead of removing what holds the odor, they buy a few weeks, and the smell returns in humid weather or when the heat runs.
Every day a broken window or roof vent stays open adds weather damage to fire damage, and an insurer expects reasonable steps to protect the property.
If the system ran during the fire, switching it on spreads residue to every room it serves, including clean ones. Leave it off until someone has inspected it.

Primary-source research and fact checking
We are a research desk, not a restoration company and not an insurance adjuster.
We read the federal agency guidance, the state insurance statute or the industry standard ourselves, and we publish the rule with the document it came from and the date we read it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. The counts below are taken from the pages on this site.

How this desk works
- Primary sources only. A mold rule comes from the EPA, a flood rule from FEMA and the NFIP, a claim rule from the state insurance statute. We do not cite an article that cites a source.
- Every figure carries its retrieval date. Guidance is revised and statutes are amended. A number without the date it was read cannot be checked.
- Paywalled standards are named, not quoted. IICRC S500 and S520 define the categories and classes of water and mold work. We describe their public structure and say plainly when the controlling text sits behind a purchase.
- Safety before the claim. Electricity near water, sewage, smoke and mold come first on every page where they apply. We explain the work; we do not tell you to do it yourself.
- We do not dry, remediate or rebuild anything, we do not adjust claims, and we take no payment for placement, ranking or a favorable mention.
Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
