A house fire does not end when the trucks leave. Even a small kitchen fire can leave soot on every wall, a sharp smoke smell in carpets and closets, and gallons of firefighting water soaking into drywall and subfloors. Larger fires add structural damage, compromised wiring and a long insurance process. Fire damage restoration is the work of making the home safe, removing water and debris, cleaning or replacing what smoke and soot affected, and rebuilding. This guide walks through what restoration involves, the odor-removal methods contractors use and their safety caveats, hidden damage worth checking, the mold risk that follows firefighting water, how insurance documentation usually works, how to choose a contractor and when an inspection makes sense before moving back in. It also covers wildfire smoke, which along the Colorado Front Range can affect homes that never caught fire. It summarizes EPA and U.S. Fire Administration guidance current as of 2026; anyone with breathing symptoms after smoke exposure should consult a physician.

What Does Fire Damage Restoration Involve?

Fire damage restoration is the process of returning a fire-affected home to safe, livable condition. It typically moves through a predictable sequence, although the order and scope vary with the size of the fire:

1. Safety assessment and access. The fire department or building official determines whether the structure can be entered. Utilities may be shut off until they are checked.
2. Emergency board-up and tarping. Broken windows, doors and roof openings are secured against weather, animals and theft.
3. Water removal and drying. Water used to fight the fire is extracted, and drying equipment is set up.
4. Debris removal and content pack-out. Unsalvageable materials are removed; salvageable belongings may be moved off-site for cleaning.
5. Smoke and soot cleaning. Surfaces, contents and building systems are cleaned using methods matched to the type of residue.
6. Odor control. Lingering smoke odor is treated, often in several rounds.
7. Repairs and reconstruction. Damaged drywall, insulation, flooring, cabinets, roofing and framing are replaced, typically with permits and inspections.

A small, contained fire may need only cleaning and odor treatment over a few days. A fire that reached the attic or structure may take months of reconstruction.

Safety, Board-Up and Water Removal

The first hours after a fire are about preventing more damage. The U.S. Fire Administration’s “After the Fire: Returning to Normal” booklet covers what to do in the first 24 hours, insurance considerations, valuing property, replacing documents and salvage tips, and it is worth reading before making decisions under stress.

Do not re-enter a fire-damaged home until the fire department says it is safe. Floors and ceilings can be weakened, and hidden hot spots can reignite. Utilities such as gas and electricity should be restored only after they are checked by the utility or a qualified professional.

Emergency Board-Up

Restoration companies typically board up openings and tarp damaged roofs within a day or two. Many insurance policies expect the homeowner to take reasonable steps to prevent further damage, so photograph the condition before and after board-up and keep receipts.

Firefighting Water

Water damage is often a large share of total fire damage. Hoses and sprinklers can saturate drywall, insulation, subfloors and basement areas below the fire. Extraction, dehumidifiers and air movers are used to dry the structure, with moisture readings taken to confirm materials are dry before they are closed up. The steps are similar to any flood or leak cleanup, covered in more depth in the guide to water damage restoration.

Smoke and Soot Cleaning

Smoke residue is not one thing. Restoration technicians distinguish between several types because each cleans differently:

• Dry soot from fast, hot fires burning paper or wood is powdery and can often be removed with dry-cleaning sponges and HEPA vacuuming.
• Wet or oily soot from slower, smoldering fires and burning plastics is sticky and smears easily, so it usually needs specialized cleaners.
• Protein residue from kitchen fires involving food may be nearly invisible yet carry a strong odor and discolor paint.

Methods include HEPA vacuuming, chemical sponges, detergent washing, abrasive or soda blasting on framing, and ultrasonic cleaning for some contents. Porous materials such as insulation, carpet pad and some drywall often cannot be cleaned effectively and are replaced. Soot is acidic and can etch metal, glass and finishes if left too long, which is one reason restoration companies push to start quickly.

Homeowners doing any of their own cleanup should avoid dry-sweeping soot or ash, which puts fine particles back in the air. The EPA’s wildfire ash guidance recommends misting surfaces before sweeping, wet mopping, using a HEPA vacuum, wearing gloves and long sleeves, and wearing an N95 respirator. It also advises that children, older adults and people with heart or lung disease not take part in cleanup.

Smoke Odor Removal: Methods and Safety Caveats

Smoke odor clings to porous materials and can return on humid days if the source residue is not removed. Cleaning comes first; deodorizing treatments are meant to address what remains.

Thermal Fogging

A fogger heats a deodorizing solution into a fine vapor intended to penetrate the same cracks and porous materials smoke reached. The home is usually vacated during treatment and ventilated afterward.

Ozone Treatment

Ozone generators are widely used in fire restoration, but ozone is a lung irritant. The EPA’s page on ozone generators sold as air cleaners states that relatively low amounts of ozone can cause chest pain, coughing, shortness of breath and throat irritation, and can worsen chronic respiratory diseases such as asthma. The EPA notes that high ozone concentrations are sometimes used to treat unoccupied spaces for odors, giving fire restoration as an example, but says conditions should be controlled so that no person or pet is exposed. It also notes that little is known about the chemical by-products these treatments leave behind. Practical takeaway: ozone treatment should be done only by trained technicians, in an empty, sealed space, with people, pets and plants out of the house until it has been properly ventilated.

Hydroxyl Generators

Hydroxyl generators are marketed as an alternative that can run with lower occupant risk and are sometimes used for longer treatment periods. Claims vary by manufacturer, so ask the contractor what occupancy rules they follow for the equipment they use.

Sealing and Replacing

When odor persists, contractors may seal cleaned framing and subfloors with a shellac- or specialty odor-blocking primer before rebuilding. Replacing insulation and carpet pad often removes more odor than any treatment can.

Salvaging Contents: What to Keep, Clean or Discard

Belongings often make up a large part of a fire claim, and decisions about them come fast. Restoration companies commonly offer a “pack-out,” in which salvageable items are inventoried, boxed and taken to a facility for cleaning and storage while the house is repaired. The inventory they create can double as claim documentation, so ask for a copy.

A few general patterns hold for most fires:

• Hard, non-porous items such as dishes, glass, metal and many hard plastics often clean well, even when they look badly sooted.
• Textiles and clothing can frequently be restored through specialized laundering or dry cleaning that targets smoke odor. Ordinary home washing sometimes sets the odor instead.
• Upholstered furniture and mattresses absorb smoke deeply and are harder to restore. Results vary with exposure.
• Electronics exposed to soot can corrode internally over time. Do not power them on until they have been evaluated.
• Food, medicine and cosmetics exposed to heat, smoke, soot or firefighting water are generally discarded rather than risked, including canned goods that were heated.
• Documents and photos may be recoverable by specialists, sometimes through freeze-drying when they are wet.

Before throwing anything out, photograph it and list it. Adjusters usually want to see damaged items or clear evidence of them, and a detailed list with approximate age and purchase price makes depreciation and replacement discussions far easier later.

Hidden Damage Worth Checking

Some of the most expensive fire damage is not obvious on a walk-through.

• HVAC ductwork. A running furnace or air handler can pull smoke and soot through the entire duct system and redistribute it. Ducts, the blower and the coil may need cleaning, and some flexible duct is simply replaced. The guide to air duct cleaning explains what a proper cleaning involves.
• Electrical wiring. Heat can damage insulation on wires inside walls far from visible scorching, and water can reach boxes and panels. An electrician should evaluate affected circuits before power is restored. The guide to an electrical inspection outlines what that review covers.
• Structural framing. Charred joists, rafters and studs may lose strength. An engineer or experienced contractor can assess whether members can be cleaned and sealed or must be replaced.
• Roof and attic. Fire and firefighting can open roofs and soak attic insulation.
• Gas appliances and venting. Heat and debris can damage flues and connectors. Having appliances checked before relighting is sensible, and working carbon monoxide alarms matter more than ever while equipment is being restored. The site’s CO and gas detector category lists options.

Mold Risk After Firefighting Water

Fire and mold seem like opposites, but the water used to put out a fire can set up a mold problem within days. The EPA’s guide to mold and moisture notes that if wet or damp materials are dried within 24 to 48 hours, in most cases mold will not grow. Fire scenes often miss that window: the home may be inaccessible, power may be off, and wet drywall can be hidden behind boarded windows.

Ask the restoration company to document moisture readings and to remove wet porous materials that cannot be dried in time. If musty odors or visible growth appear during reconstruction, a mold assessment before walls are closed up is far cheaper than opening them later.

Insurance and Documentation

Insurance terms vary by policy and insurer, so the policy language governs. In general terms, many homeowners policies cover fire and smoke damage to the structure and contents, and many include additional living expenses while the home is uninhabitable. Limits, deductibles and how depreciation is handled differ.

Practical steps that commonly help a claim:

• Notify the insurer promptly and ask about the claims process and any requirements for emergency work.
• Photograph and video every room before cleanup begins, including closets, ceilings and contents.
• Keep receipts for board-up, temporary housing, meals and essential purchases.
• Build a contents inventory room by room. The USFA booklet includes guidance on valuing property.
• Do not discard damaged items until the adjuster has documented them, unless they pose a health hazard.
• Get the restoration scope in writing and ask the adjuster to review it before work proceeds.

You generally have the right to choose your own restoration contractor, though insurers may suggest preferred vendors. Some homeowners hire a public adjuster for large losses; they work for the policyholder and typically charge a percentage of the settlement.

How Much Does Fire Damage Restoration Cost?

Costs depend on the size of the fire, how far smoke traveled, how much water was used and how much rebuilding is required. As rough industry estimates rather than quotes, smoke and soot cleaning for a limited area might run from several hundred to a few thousand dollars, while whole-house smoke cleaning and odor treatment can run into the thousands or tens of thousands. Fires requiring structural reconstruction can approach the cost of building new rooms. Contents cleaning, pack-out and storage are often billed separately. Many restoration companies price insurance work using estimating software that adjusters also use, which can make comparing scopes easier.

Choosing a Restoration Contractor

After a fire, homeowners are often approached by contractors quickly, sometimes the same day. Take a breath before signing anything.

• Credentials: IICRC certification is a widely recognized industry credential for cleaning and restoration technicians, including fire and smoke restoration. Ask which technicians hold it.
• Licensing and insurance: confirm general liability and workers’ compensation coverage, and any local contractor licensing required for reconstruction.
• Written scope: the estimate should separate emergency services, cleaning, odor treatment, contents and reconstruction.
• Direction to pay: read any assignment of benefits or direction-to-pay document carefully before signing.
• References: ask for recent fire jobs of similar size.

When to Get an Inspection Before Re-Occupying

Restoration companies clean and rebuild; they do not always provide an independent view of the result. An inspection before moving back in, or before buying a home with a fire history, can catch issues such as unrepaired wiring, missing smoke alarms, lingering odor sources, attic soot and moisture problems. Inspectors work within a visual scope and may recommend an electrician, HVAC contractor or engineer for specific concerns. The guide to hiring a home inspector explains how to scope an inspection, and specialty evaluations are covered in specialty inspections.

Before re-occupying, confirm that smoke alarms on every level work, CO alarms are installed near sleeping areas where fuel-burning appliances are present, and the HVAC system has been cleaned or cleared.

Wildfire Smoke on the Front Range

Wildfires in and near the foothills, along with smoke drifting in from fires across the West, mean many Front Range homes deal with smoke even though they never burned. The EPA’s wildfires and indoor air quality guidance explains that outdoor smoke can enter homes through open windows and doors, bathroom and kitchen exhaust fans, and HVAC systems with fresh-air intakes, as well as through gaps in the building. The biggest health threat from smoke, according to the EPA, is fine particles.

Homes near a fire perimeter can have ash in attics, on window sills and in duct systems, plus odor in carpets and upholstery. Light smoke exposure often responds to HEPA vacuuming, wet wiping, replacing HVAC filters and airing out. Heavier exposure may justify professional cleaning. An indoor monitor can help show whether particle levels have returned to normal after an event; the site’s air quality monitor category lists options. The EPA advises considering duct cleaning after a fire only if ducts are clogged with debris or particles are actually blowing out of supply registers.
