Structural Fire Damage Cleaning in Moraga, CA
The drywall is gone, and now you are staring at blackened studs, scorched joists and a charred roof deck. 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 Moraga 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
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. Ask for a line-item written estimate before the first bag of media is opened.
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. 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.
Structural Cleaning Services From Rafters to Slab
Furniture and debris are a separate job. 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.
- 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. 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 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
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 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. 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. 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.
Plan for containment, because blasting throws soot and media into every corner it can reach. 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. 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. First they confirm the roof deck and floors will hold weight and that the exposed circuits are dead.
- 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. 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. 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.
My contractor brother-in-law said all the black studs had to go. The crew lead probed each one with an awl and showed me that most were just surface char. 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.
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. 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 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?
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. 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. 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. 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. An engineer's report on trusses, headers, beams, steel and badly charred joists protects you and supports the claim. Your local building department may also require one before the walls close.
