Structural Fire Damage Cleaning in Cold Spring, MN
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 Cold Spring 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
- Sealer applied to lock in residual 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. 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. Timing depends on which crews near Cold Spring 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.
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. 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
Furniture and debris are a separate job. 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. Deep char that eats into the section of a joist or truss chord means sistering or replacement.

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. 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 and columns are cleaned of soot and checked for warping or sag, which goes 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.
Ask your contractor which method they recommend for each area and why. 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
Say which parts of the structure are open now, such as walls, attic, crawlspace, masonry or steel. Let us know if an adjuster, engineer or roofer has already visited.

Mobile Crew on Site
An independent crew shows up with its compressor, blast gear, poly and air scrubbers. First they confirm the roof deck and floors will hold weight and that the exposed circuits are dead.

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. 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
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.
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.
Common Questions About Cleaning Charred Framing
How do crews decide if a charred stud can stay?
The test is simple: 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 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. 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?
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. The building department may ask for it before signing off on the rebuild.
