Structural Fire Damage Cleaning in Markham, IL
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 Markham who clean the framing, masonry and steel itself.
- 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. 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. 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. Get a written, itemized estimate in hand before any blasting begins.
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.
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. 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.
- Members marked clean, sister or replace
- 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
For a few blackened studs or a small closet fire, wire brushes, sanding discs and a HEPA-shrouded grinder may be all it takes. Hand work is slower but sensible where a blast rig would be too much.
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. Attic jobs start by vacuuming out the smoky blown-in or batt insulation so the rafters and roof deck can be reached.
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.
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
Describe what is exposed: open stud walls, an attic, a crawlspace, block or steel. Let us know if an adjuster, engineer or roofer has already visited.

Mobile Crew on Site
The contractor arrives with a compressor, blasting equipment and containment materials. 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. A written, itemized quote covering area, blast method, encapsulant and attic insulation comes before any work starts.

Blasting, Sealing and Walkthrough
After blasting and HEPA cleanup, the framing gets its sealer coat, and you walk the bare structure with the crew lead. 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. 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. The contractor cleaned the block and the beam, then had an engineer check the steel for warping. No smell now, even with the windows shut.
Your Structural Fire Cleaning Questions Answered
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. An encapsulating sealer traps what is left so the odor does not seep back through the finished walls. 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. Loose-fill and batts act like a giant filter for smoke, and hose water often soaks them as well. 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?
Usually yes, though masonry takes more effort than drywall because soot sinks into the pores. 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. The building department may ask for it before signing off on the rebuild.
