Structural Fire Damage Cleaning in Millbrae, CA
With the wallboard torn out, what is left is a skeleton of black studs, scorched rafters and smoke-stained block. 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 Millbrae contractors who clean the bare structure down to sound wood.
- Soda blasting, dry ice blasting and wire brushing
- Every stud and joist probed for char depth
- Cleaned wood encapsulated against lingering 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
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.
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
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. Deep char that eats into the section of a joist or truss chord means sistering or replacement.

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
Dry ice pellets hit the surface and turn straight into gas, so there is no media left behind to sweep up. 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
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
Cleaned framing gets a coat of shellac-based or specialty encapsulant to lock in any odor left deep in the wood. 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. Expect a vapor barrier to be pulled and replaced if smoke or hose water soaked it.
Ask your contractor which method they recommend for each area and why. A good crew may soda blast the open walls, dry ice the attic around the wiring and hand sand a few studs near the panel.
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 how they will protect finished rooms and windows that were not damaged.

Phone the Dispatcher
Say which parts of the structure are open now, such as walls, attic, crawlspace, masonry or steel. Let us know if an adjuster, engineer or roofer has already visited.

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
Every exposed member gets probed with an awl and marked clean, sister or replace, and anything borderline goes to a structural engineer. A written, itemized quote covering area, blast method, encapsulant and attic insulation comes before any work starts.

Blasting, Sealing and Walkthrough
After blasting and HEPA cleanup, the framing gets its sealer coat, and you walk the bare structure with the crew lead. 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.
My contractor brother-in-law said all the black studs had to go. 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. They scrubbed and blasted the block, cleaned the beam and had the engineer confirm it had not sagged. 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. An awl or screwdriver pushed into the black surface shows how deep the char goes, and wood that is firm just under a thin crust can usually be blasted and sealed. 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 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. 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?
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. Your local building department may also require one before the walls close.
