Fire Damage: What Gets Cleaned, What Gets Replaced, and What Gets Missed

Not all soot is the same

A fast-burning fire with plenty of oxygen produces dry, powdery soot that's easier to clean from hard surfaces. A slow, smoldering fire produces wet, oily soot that's sticky, greasy, and costs two to three times more to clean. A kitchen grease fire produces protein-based soot that's nearly invisible but generates a powerful, lingering odor that penetrates every porous surface.

The IICRC S540 standard classifies these soot types and prescribes specific cleaning methods for each. Using the wrong approach, like wiping oily soot with a dry cloth, drives residue deeper into materials and can make the damage permanent. This is why professional assessment matters before anyone touches anything.

Surfaces that can be professionally restored

Hard, non-porous surfaces like metal, glass, sealed stone, and solid surface countertops can usually be cleaned and restored for $2 to $5 per square foot. Some fabrics and upholstery can be saved if the soot hasn't deeply penetrated the fibers, with professional textile cleaning running $50 to $200 per item. Hardwood floors can often be sanded and refinished at $3 to $6 per square foot if the damage is limited to the surface layer.

Electronics and appliances may be restorable depending on heat exposure, but here's the catch: internal soot deposits can cause failures weeks or months later. A certified restoration company should evaluate each item individually and give you a written recommendation.

Materials that must be replaced

Porous materials that have absorbed soot or smoke odor are usually done. Drywall absorbs smoke at a molecular level.

Carpet padding is a sponge for odor. Upholstered furniture with heavy soot penetration won't come clean. Anything directly burned or charred is obviously gone.

Soft goods like clothing may be restorable through ozone treatment or specialized cleaning, but heavily affected items are often cheaper to replace than to clean. When the cost of professional cleaning approaches the replacement cost, replacement is the better path.

Smoke odor doesn't fade on its own

Smoke odor penetrates drywall, wood framing, carpet fibers, and every inch of your HVAC ductwork. Professional odor removal may involve thermal fogging, ozone treatment, hydroxyl generators, or sealing surfaces with odor-blocking primers like Kilz or BIN shellac. Your HVAC system needs professional cleaning and filter replacement.

Don't assume the smell will dissipate with time. It won't. I've heard from homeowners who waited months hoping it would fade.

It never does.

Build your claim on evidence, not memory

Don't clean or throw away anything until it's been photographed and documented. Create a detailed inventory of every damaged item with description, approximate age, and replacement cost. Gather supporting records: purchase receipts, credit card statements, photos from social media showing items in your home.

Ask your insurer about having a restoration company do a formal contents evaluation, cleaning vs. replacement, item by item. This evaluation is a standard part of the Xactimate contents scope under Coverage C of your policy.
