What Makes Framing Work Different
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
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
Media blasting depends on square footage, the media used and how hard the space is to get into. 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.
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. Wait for the contractor to check that the structure is safe, and keep people off floors that sit over a burned crawlspace or basement.

This is not contents cleaning and it is not debris haul-out. This page is about the framing, masonry and steel that actually carry the load.
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. Deep char that eats into the section of a joist or truss chord means sistering or replacement.
- 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. 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 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
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 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. 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. 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.
Plan for containment, because blasting throws soot and media into every corner it can reach. 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.

Phone the Dispatcher
Describe what is exposed: open stud walls, an attic, a crawlspace, block or steel. Mention if a roofer, engineer or adjuster has already been out.
- 2
Mobile Crew on Site
The contractor arrives with a compressor, blasting equipment and containment materials. They check that the roof and floor are safe to walk and that power to the open walls is off.
- 3
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. Do a sniff test on a warm afternoon, and ask for photos of every marked member before the rebuild closes the walls.

Notes From People We Connected
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. 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 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. 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. 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 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 pellets vanish on impact, so cleanup is easier and it works well around wiring, but it is louder and 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. 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?
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. 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?
You may not on a small job, but any doubtful load-bearing member calls for one. 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.
