Somebody now has to decide what gets blasted clean, what gets sistered and what gets replaced. Unify Fire Solutions puts you in touch with independent, licensed and insured Ukiah 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

What Makes Framing Work Different
Hang new drywall over sooty, smoky studs and the smell comes back through the paint on the first warm day. This stage decides whether your rebuilt rooms smell fresh or smell burned for years.
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. Burned joists and decking can fail under one person's weight, and open wiring may still carry current. Let the crew confirm the structure will hold before anyone goes up, and keep everyone off the floor above a burned basement or crawlspace.

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
An awl pushed into a charred stud tells the story: if it stops in sound wood after a thin layer of char, the member is usually a cleaning candidate. When the char cuts deep into a joist or a truss web, the member gets sistered or swapped out.
- Members marked clean, sister or replace
- Structural engineer called in for questionable beams, trusses and headers
- 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. Expect fine dust and residue that has to be contained and HEPA vacuumed when the blasting is done.
Dry Ice Blasting
Dry ice pellets hit the surface and turn straight into gas, so there is no media left behind to sweep up. It works well in tight attics and around wiring, though it costs more and is noisy.
- Hearing protection and ventilation required
- Good choice when residue would be a problem
Wire Brushing and Sanding
Small, isolated char spots are often handled by hand with wire brushes and sanders tied into a HEPA vacuum. 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 get cleaned and inspected for any heat warping, with doubts sent 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.

Probe, Mark and Quote
They test each stud, joist and rafter with an awl, tag it, and flag anything doubtful for an 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. Smell the space on a warm day and get photos of each tagged member before anyone hangs drywall.

What Callers Said About Their Structural Crew
After the attic fire, the rafters were black and the blown-in insulation was a wet mess. They vacuumed out the insulation, dry iced the rafters around the wiring and sealed it all. 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 pushed an awl into each one and showed me the wood was solid under a thin crust. They soda blasted and sealed them, and only three were swapped.
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. Many crews use both on the same house.
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?
If smoke reached the attic, almost always yes. 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?
Most of the time, but brick and block hold soot in their pores and need more than a wipe. Crews use alkaline masonry cleaners and stiff brushes, and soda or other media blasting for heavy buildup. 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?
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.
