Why the Bare Structure Needs Its Own Crew
Hang new drywall over sooty, smoky studs and the smell comes back through the paint on the first warm day. Cleaning the structure is the step that decides whether the rebuild smells like a new house or a campfire.
Licensed & Insured Independent Pros
The contractors we connect you with are independent businesses carrying their own license and insurance. Verify both, and ask whether the crew follows the IICRC S700 standard for fire and smoke work.
Upfront Written Estimates
Blasting is priced by surface area, media and access, and attics and crawlspaces cost more to reach. Get a written, itemized estimate in hand before any blasting begins.
Rapid Local Dispatch
A real person answers around the clock, and the search for a crew begins on that call. How fast someone arrives depends on availability and distance, often within the same day.
Blasting Rigs and Probing Tools
Structural crews bring soda blast pots, dry ice units, big compressors, HEPA vacs, air scrubbers and a sharp awl to test every member.
Stay out of a fire-damaged attic, and never walk a charred roof deck to check it. Weakened joists and burned-through sheathing can give way without warning, and exposed wiring may still be live. Let the crew confirm the structure will hold before anyone goes up, and keep everyone off the floor above a burned basement or crawlspace.
Cleaning the Building From the Roof Deck Down
This is not contents cleaning and it is not debris haul-out. It is the work done on the wood, block, brick and steel that hold your house up.
Char Depth Probing and Member Decisions
Pressing an awl into the blackened wood shows how deep the char goes; a shallow crust over firm wood usually means it can be cleaned. When the char cuts deep into a joist or a truss web, the member gets sistered or swapped out.

- Photos of each marked member for the claim
Soda Blasting
Sodium bicarbonate is softer than wood, so it strips soot and light char off studs, joists and roof decking without gouging the grain. It leaves a fine white dust and some residue, so containment and a thorough HEPA vacuum afterward are part of the job.
Dry Ice Blasting
With dry ice the pellets sublimate on impact, so there is nothing left on the floor but the soot itself. It suits cramped attics and areas around wiring, but it runs louder and pricier than soda.
- Hearing protection and ventilation required
- Good choice when residue would be a problem
Wire Brushing and Sanding
For a few blackened studs or a small closet fire, wire brushes, sanding discs and a HEPA-shrouded grinder may be all it takes. Hand work is slower but sensible where a blast rig would be too much.
Brick, Block, Concrete and Steel Beams
Porous brick, block and concrete trap soot deep in the surface, so crews use alkaline detergents, scrub brushes or blast media to lift it. Steel beams and columns are cleaned of soot and checked for warping or sag, which goes to the engineer.
Encapsulation and Attic Insulation Removal
Even well-blasted wood can hold faint odor in its pores, so crews roll or spray a pigmented shellac-based or specialty encapsulating sealer over cleaned framing. In the attic, smoke-soaked blown-in or batt insulation is vacuumed out with a high-powered insulation vac before the rafters and decking are cleaned.
Crawlspaces get the same treatment on a smaller, dirtier scale: floor joists, sill plates and the underside of the subfloor are probed, blasted where needed and sealed. Expect a vapor barrier to be pulled and replaced if smoke or hose water soaked it.
Have the contractor explain the method they plan for each part of the house. It is common to see soda in open walls, dry ice in the attic and hand sanding near the electrical panel on the same job.
Containment matters here, since blast media and loosened soot travel anywhere the air moves. Expect poly over openings, taped-off HVAC returns and air scrubbers pulling the space under negative pressure during blasting. Ask how they will protect finished rooms and windows that were not damaged.

Mobile Crew on Site
The contractor arrives with a compressor, blasting equipment and containment materials. First they confirm the roof deck and floors will hold weight and that the exposed circuits are dead.

Probe, Mark and Quote
Every exposed member gets probed with an awl and marked clean, sister or replace, and anything borderline goes to a structural engineer. You get a written, line-item quote listing square footage, method, sealer and insulation removal before any work starts.

Blasting, Sealing and Walkthrough
Once the wood is blasted, vacuumed and sealed, the crew lead walks you through the open structure. Do a sniff test on a warm afternoon, and ask for photos of every marked member before the rebuild closes the walls.
What Callers Said About Their Structural Crew
The attic fire left every rafter black and the insulation soaked. They vacuumed out the insulation, dry iced the rafters around the wiring and sealed it all. Two rafters were cut deep enough that they called in an engineer, and those got sistered.
I assumed every black stud in the hallway had to be replaced. The crew lead pushed an awl into each one and showed me the wood was solid under a thin crust. Soda blasting and a coat of sealer saved most of the wall.
The fire in our lower level left the block walls and the steel beam coated in soot. The contractor cleaned the block and the beam, then had an engineer check the steel for warping. No smell now, even with the windows shut.
Your Structural Fire Cleaning Questions Answered
How do crews decide if a charred stud can stay?
They probe it. Push an awl into the char, and if it hits solid wood after a shallow layer, the stud is usually a cleaning job. Members with deep char, splitting or a lost cross section get sistered or replaced, and anything structural in doubt goes to a licensed structural engineer.
What is the difference between soda blasting and dry ice blasting?
Soda blasting uses sodium bicarbonate media that is gentle on wood and helps neutralize odor, but it leaves dust and residue to clean up. Dry ice pellets vanish on impact, so cleanup is easier and it works well around wiring, but it is louder and usually costs more. It is common to see both on one job.
Why seal the framing if it has already been cleaned?
Wood is porous, and smoke molecules sit deep in the grain where no blasting can reach. A shellac-based or specialty encapsulant locks that residual odor in so it cannot off-gas through the new drywall. Sealing dirty wood does not work, so the cleaning has to come first.
Does the attic insulation have to come out after a fire?
In most cases where smoke got into the attic, it does. Blown-in and batt insulation trap smoke and soot like a filter, and many get soaked by hose water too. Crews vacuum it out with a truck-mounted or portable insulation vac so the rafters and decking can be inspected and cleaned before new insulation goes in.
Can soot be cleaned off brick and concrete block?
Usually yes, though masonry takes more effort than drywall because soot sinks into the pores. Expect alkaline detergents and scrub brushes for light staining and media blasting for thick deposits. Spalling or cracked masonry is a structural question for a mason or engineer.
Do I need a structural engineer for fire-damaged framing?
You may not on a small job, but any doubtful load-bearing member calls for one. Trusses, beams, headers, steel and heavily charred joists are where an engineer's letter protects you and helps the claim. The building department may ask for it before signing off on the rebuild.
