Structural Fire Damage Cleaning in Delafield, 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 connects you with independent, licensed and insured contractors in Delafield 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
Blasting is priced by surface area, media and access, and attics and crawlspaces cost more to reach. Ask for a line-item written estimate before the first bag of media is opened.
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 Delafield 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. 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
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
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
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. 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. 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. 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.
Containment matters here, since blast media and loosened soot travel anywhere the air moves. Expect poly over openings, taped-off HVAC returns and air scrubbers pulling the space under negative pressure during blasting. Ask how they will protect finished rooms and windows that were not damaged.

Phone the Dispatcher
Say which parts of the structure are open now, such as walls, attic, crawlspace, masonry or steel. Mention if a roofer, engineer or adjuster has already been out.
- 2
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.
- 3
Probe, Mark and Quote
They test each stud, joist and rafter with an awl, tag it, and flag anything doubtful for an 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. 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.
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. 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. 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?
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. 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. Crews vacuum it out with a truck-mounted or portable insulation vac so the rafters and decking can be inspected and cleaned before new insulation goes 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. 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.
