Structural Fire Damage Cleaning in Penryn, CA
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 Penryn 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

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. 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. 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. Timing depends on which crews near Penryn 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. Let the crew confirm the structure will hold before anyone goes up, and keep everyone off the floor above a burned basement or crawlspace.
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
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
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
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.
Containment matters here, since blast media and loosened soot travel anywhere the air moves. The crew hangs poly over doorways, masks off the HVAC returns and runs air scrubbers under negative pressure while they work. Ask how they will protect finished rooms and windows that were not damaged.

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
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. Smell the space on a warm day and get photos of each tagged member before anyone hangs drywall.

What Callers Said About Their Structural Crew
After the attic fire, the rafters were black and the blown-in insulation was a wet mess. They vacuumed out the insulation, dry iced the rafters around the wiring and sealed it all. Two rafters were cut deep enough that they called in an engineer, and those got sistered.
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. 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.
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. Members with deep char, splitting or a lost cross section get sistered or replaced, and anything structural in doubt goes to a licensed structural engineer.
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 leaves no media behind and works well near wiring, but the equipment is noisy and the job 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. 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?
Usually yes, though masonry takes more effort than drywall because soot sinks into the pores. 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. The building department may ask for it before signing off on the rebuild.
