Structural Fire Damage Cleaning in Spearfish, SD
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 connects you with independent, licensed and insured contractors in Spearfish who clean the framing, masonry and steel itself.
- Soda, dry ice and hand cleaning of framing
- Char depth probed member by member
- Sealer applied to lock in residual 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. 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. 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. Ask for a line-item written estimate before the first bag of media is opened.
Rapid Local Dispatch
Day or night, a dispatcher picks up and starts looking for a structural cleaning crew right away. 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. 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
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. 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. 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
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
Fireplace surrounds, block foundation walls and concrete slabs hold soot in their pores, and alkaline cleaners, scrubbing or blasting pull it out. Steel beams and columns are cleaned of soot and checked for warping or sag, which goes 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.
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.

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
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
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.

What Callers Said About Their Structural Crew
The attic fire left every rafter black and the insulation soaked. 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.
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?
The test is simple: 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. Deep char, cracks or a reduced cross section mean sistering or replacement, with a structural engineer making the call on anything questionable.
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. Many crews use both on the same house.
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?
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. 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. 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.
