Structural Fire Damage Cleaning in Bothell, WA
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 Bothell 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
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. This stage decides whether your rebuilt rooms smell fresh or smell burned for years.
Licensed & Insured Independent Pros
Each contractor on our referral list is an independent, licensed and insured local company. 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
This trade runs on gear most remodelers do not own: soda blast pots, dry ice blasters, tow-behind compressors, HEPA vacuums, air scrubbers and an awl for probing char.
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.
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. 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
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
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. 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 get cleaned and inspected for any heat warping, with doubts sent 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. 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. 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 what the plan is to shield the undamaged rooms, floors and glass.

- 1
Phone the Dispatcher
Describe what is exposed: open stud walls, an attic, a crawlspace, block or steel. Let us know if an adjuster, engineer or roofer has already visited.
- 2
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.
Notes From People We Connected
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.
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. The basement smells normal again, even closed up.
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. 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 leaves no media behind and works well near wiring, but the equipment is noisy and the job 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. 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. 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?
Usually yes, though masonry takes more effort than drywall because soot sinks into the pores. 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?
You may not on a small job, but any doubtful load-bearing member calls for one. 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.
