Structural Fire Damage Cleaning in Willows, CA
With the wallboard torn out, what is left is a skeleton of black studs, scorched rafters and smoke-stained block. The question is which members can be cleaned, which need a sister, and which have to come out. Unify Fire Solutions puts you in touch with independent, licensed and insured Willows contractors who clean the bare structure down to sound wood.
- Soda blasting, dry ice blasting and wire brushing
- Char depth probed member by member
- Sealer applied to lock in residual odor

Why the Bare Structure Needs Its Own Crew
Close up the walls over dirty framing and the smoke odor bleeds right back through the new finish. 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
Media blasting depends on square footage, the media used and how hard the space is to get into. Get a written, itemized estimate in hand before any blasting begins.
Rapid Local Dispatch
Day or night, a dispatcher picks up and starts looking for a structural cleaning crew right away. 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.
Do not climb into a burned attic or walk a scorched roof deck to look for yourself. 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
Furniture and debris are a separate job. This page is about the framing, masonry and steel that actually carry the load.
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. Deep char that eats into the section of a joist or truss chord means sistering or replacement.

Soda Blasting
Baking soda media knocks soot and surface char off framing while leaving the grain mostly intact. 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. It is slow on big areas but precise where blasting would be overkill.
Brick, Block, Concrete and Steel Beams
Fireplace surrounds, block foundation walls and concrete slabs hold soot in their pores, and alkaline cleaners, scrubbing or blasting pull it out. 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. Attic jobs start by vacuuming out the smoky blown-in or batt insulation so the rafters and roof deck can be reached.
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. A smoke-stained or wet vapor barrier usually comes out and goes back new.
Ask your contractor which method they recommend for each area and why. 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. The crew hangs poly over doorways, masks off the HVAC returns and runs air scrubbers under negative pressure while they work. Ask what the plan is to shield the undamaged rooms, floors and glass.

Phone the Dispatcher
Describe what is exposed: open stud walls, an attic, a crawlspace, block or steel. Let us know if an adjuster, engineer or roofer has already visited.

Mobile Crew on Site
The contractor arrives with a compressor, blasting equipment and containment materials. They check that the roof and floor are safe to walk and that power to the open walls is off.
- 3
Probe, Mark and Quote
They test each stud, joist and rafter with an awl, tag it, and flag anything doubtful for an engineer. A written, itemized quote covering area, blast method, encapsulant and attic insulation comes 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.

Notes From People We Connected
After the attic fire, the rafters were black and the blown-in insulation was a wet mess. The crew pulled the insulation, dry ice blasted the rafters and rolled sealer on everything. An engineer looked at two deeply charred rafters and they were sistered instead of torn out.
I assumed every black stud in the hallway had to be replaced. The crew lead probed each one with an awl and showed me that most were just surface char. 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.
Common Questions About Cleaning Charred Framing
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 leaves no media behind and works well near wiring, but the equipment is noisy and the job 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. Sealer only works over clean framing, never as a shortcut over soot.
Does the attic insulation have to come out after a fire?
In most cases where smoke got into the attic, it does. Loose-fill and batts act like a giant filter for smoke, and hose water often soaks them as well. It is vacuumed out with an insulation vac so the rafters and roof deck can be probed, blasted and sealed before anything new is blown in.
Can soot be cleaned off brick and concrete block?
Most of the time, but brick and block hold soot in their pores and need more than a wipe. Expect alkaline detergents and scrub brushes for light staining and media blasting for thick deposits. Heat-cracked or spalled block and brick should be looked at by an engineer or mason.
Do I need a structural engineer for fire-damaged framing?
Not for every job, but for anything load-bearing that looks questionable, yes. 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.
