Structural Fire Damage Cleaning in Gregory, SD
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 Gregory contractors who clean the bare structure down to sound wood.
- Soda, dry ice and hand cleaning of framing
- 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. Cleaning the structure is the step that decides whether the rebuild smells like a new house or a campfire.
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
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. Timing depends on which crews near Gregory are free, and it is often 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.
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. Let the crew confirm the structure will hold before anyone goes up, and keep everyone off the floor above a burned basement or crawlspace.

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.

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
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
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
Fireplace surrounds, block foundation walls and concrete slabs hold soot in their pores, and alkaline cleaners, scrubbing or blasting pull it out. 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.
Ask your contractor which method they recommend for each area and why. 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. Expect poly over openings, taped-off HVAC returns and air scrubbers pulling the space under negative pressure during blasting. Ask what the plan is to shield the undamaged rooms, floors and glass.

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. 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 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. The basement smells normal again, even closed up.
Your Structural Fire Cleaning Questions Answered
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. 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 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. It is common to see both on one job.
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?
If smoke reached the attic, almost always yes. 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?
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.
