Structural Fire Damage Cleaning in Alpine, 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 Alpine contractors who clean the bare structure down to sound wood.
- Soda, dry ice and hand cleaning of framing
- Every stud and joist probed for char depth
- Cleaned wood encapsulated against lingering odor

What Makes Framing Work Different
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. Check the paperwork yourself and ask if their process lines up with IICRC S700.
Upfront Written Estimates
Blasting is priced by surface area, media and access, and attics and crawlspaces cost more to reach. Ask for a line-item written estimate before the first bag of media is opened.
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. Wait for the contractor to check that the structure is safe, and keep people off floors that sit over a burned crawlspace or basement.

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.

- 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. 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
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. Attic jobs start by vacuuming out the smoky blown-in or batt insulation so the rafters and roof deck can be reached.
Under the house, the crew probes the joists, sill plates and subfloor underside, then blasts and seals what can stay. A smoke-stained or wet vapor barrier usually comes out and goes back new.
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 what the plan is to shield the undamaged rooms, floors and glass.

Phone the Dispatcher
Say which parts of the structure are open now, such as walls, attic, crawlspace, masonry or steel. Mention if a roofer, engineer or adjuster has already been out.

Mobile Crew on Site
An independent crew shows up with its compressor, blast gear, poly and air scrubbers. First they confirm the roof deck and floors will hold weight and that the exposed circuits are dead.

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. 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. The crew pulled the insulation, dry ice blasted the rafters and rolled sealer on everything. 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.
Our basement fire blackened the block walls and the steel beam over the family room. 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?
The test is simple: 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. Deep char, cracks or a reduced cross section mean sistering or replacement, with a structural engineer making the call on anything questionable.
What is the difference between soda blasting and dry ice blasting?
Soda media is mild on the grain and helps with odor, though it leaves a white dust that needs a full HEPA cleanup. 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?
Smoke gets deep into the pores of the wood, past what blast media can reach. An encapsulating sealer traps what is left so the odor does not seep back through the finished walls. Sealer only works over clean framing, never as a shortcut over soot.
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. 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?
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. 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. An engineer's report on trusses, headers, beams, steel and badly charred joists protects you and supports the claim. The building department may ask for it before signing off on the rebuild.
