Structural Fire Damage Cleaning in Dane, WI
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 Dane 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

Why the Bare Structure Needs Its Own Crew
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
Each contractor on our referral list is an independent, licensed and insured local company. Check the paperwork yourself and ask if their process lines up with IICRC S700.
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.
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. This page is about the framing, masonry and steel that actually carry the load.
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
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 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. 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.
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. 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.
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 how they will protect finished rooms and windows that were not damaged.

Mobile Crew on Site
An independent crew shows up with its compressor, blast gear, poly and air scrubbers. They check that the roof and floor are safe to walk and that power to the open walls is off.

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
Once the wood is blasted, vacuumed and sealed, the crew lead walks you through the open structure. 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
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 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.
Our basement fire blackened the block walls and the steel beam over the family room. 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. 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. 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. 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?
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. 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.
