Structural Fire Damage Cleaning in Cotati, CA
The drywall is gone, and now you are staring at blackened studs, scorched joists and a charred roof deck. 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 Cotati contractors who clean the bare structure down to sound wood.
- Soda blasting, dry ice blasting and wire brushing
- Char depth probed member by member
- Cleaned wood encapsulated against lingering 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
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. Timing depends on which crews near Cotati are free, and it is often 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.
Structural Cleaning Services From Rafters to Slab
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. 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
Baking soda media knocks soot and surface char off framing while leaving the grain mostly intact. 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 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
Small, isolated char spots are often handled by hand with wire brushes and sanders tied into a HEPA vacuum. Hand work is slower but sensible where a blast rig would be too much.
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
Cleaned framing gets a coat of shellac-based or specialty encapsulant to lock in any odor left deep in the wood. 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. Expect a vapor barrier to be pulled and replaced if smoke or hose water soaked it.
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. 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.

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.

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
After blasting and HEPA cleanup, the framing gets its sealer coat, and you walk the bare structure with the crew lead. Smell the space on a warm day and get photos of each tagged member before anyone hangs drywall.
Notes From People We Connected
The attic fire left every rafter black and the insulation soaked. 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 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.
Your Structural Fire Cleaning Questions Answered
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 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. 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. 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. 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.
