Fire damage restoration with dry ice: removing soot and fire odour without residue
Professional fire damage restoration by dry ice blasting, up to 70% faster than conventional methods. Gentle on building fabric, timber and electronics. Mobile operations across Germany.
Fire damage restoration: dry ice blasting
After a fire, every hour counts. Soot particles, combustion gases and pollutants penetrate surfaces and, if restoration is delayed, cause irreversible damage to the building fabric, machinery and contents.
Dry ice blasting is the method of choice in professional fire damage restoration. Unlike sandblasting or chemical cleaners, dry ice works without residue: on impact, the CO₂ sublimates directly into gas, with no moisture, no chemicals and no abrasives. The building fabric remains intact, and sensitive surfaces such as timber beams, stucco or listed elements are protected.
Particularly relevant: insurers increasingly recognise dry ice blasting as a cost-effective restoration method, as it considerably shortens the overall restoration time and avoids costly secondary damage from moisture or chemicals. Under the duty to mitigate loss (§ 82 VVG, German Insurance Contract Act), the use of dry ice may even be required.
Typical applications:
Fire damage restoration
Dry ice blasting solves industry-specific cleaning tasks where conventional methods reach their limits.
Roof structures & timber constructions
Soot removal from rafters, purlins and timber framing, without damaging the timber structure. Ideal for listed buildings.
Masonry & concrete surfaces
Walls, ceilings, clinker brick and exposed concrete are freed of soot and fire residues, without exposure to water or chemical contamination.
Steel structures & metalwork
Steel beams, railings and metal structures are efficiently cleaned of soot, paint residues and incipient corrosion.
Control cabinets & electrical systems
Electrical components can be cleaned in situ: dry ice is electrically non-conductive and leaves no moisture.
Fire odour neutralisation
The thermal shock effect releases odour-causing particles (PAHs, dioxins) from porous surfaces, acting more deeply than ozone or chemical neutralisers.
Façades & exterior areas
Render, clinker brick, natural stone and plastered surfaces are cleaned of soot deposits and fire marks without damaging the surface.
Fire damage restoration: why dry ice?
Fire damage restoration: these industry-specific benefits make dry ice blasting the most efficient cleaning solution.
Up to 70% faster than manual cleaning
In a single pass, dry ice blasting achieves what takes manual or chemical methods several working days. One documented case: 8 days instead of an estimated 16 days, saving approx. €18,000 in labour costs.
Gentle on the substrate: ideal for timber, stucco & heritage
Unlike sandblasting, dry ice does not abrade any surface (Mohs hardness 2). Timber beams, stucco elements and historic building components remain intact: a decisive advantage for listed buildings.
No secondary damage from moisture
Sandblasting leaves blasting media behind, and high-pressure water cleaning introduces thousands of litres of water into the building. Dry ice sublimates without residue: no risk of mould, no drying times, no waste water.
In line with insurance requirements & documented
Complete photo documentation (before/after), audit-ready reports and transparent fixed prices. Insurers recognise dry ice blasting as a cost-efficient restoration method.
Effective removal of different types of soot
Protein soot (sticky, organic), plastic soot (toxic, containing PAHs), charcoal soot (deeply penetrating): dry ice blasting dislodges all types of soot through the thermal shock effect.

Dry ice vs. alternatives
Fire damage restoration: a direct comparison shows why companies are switching to dry ice blasting.
| Criterion | Dry ice | Sandblasting | Chemical cleaning |
|---|---|---|---|
| Speed | Up to 70% faster | Slow + rework | Dwell time + several passes |
| Building fabric | Fully preserved (Mohs 2) | Abrasive: wood/stucco at risk | Chemical contamination possible |
| Moisture | Zero: sublimates without residue | Dry, but blasting media residues | Water-based: risk of mould |
| Secondary waste | Only dislodged soot | Blasting media + soot | Chemical waste water |
| Heritage protection | Ideal: non-abrasive | Not recommended | Limited |
| Electronics | Yes: non-conductive | No | No |

Yes, in most cases. Insurers recognise dry ice blasting as a cost-effective method. Under the duty to mitigate loss (§ 82 VVG), its use may even be required. We provide documentation in line with insurance requirements.
All common types: protein soot (sticky, organic), plastic soot (toxic, containing PAHs) and charcoal soot (deeply penetrating). The thermal shock effect at −78.5 °C also releases stubborn particles from pores.
As quickly as possible. Within the first 48 to 72 hours, damage is often still reversible. Soot particles cause corrosion on contact with moisture, and combustion gases such as HCl attack materials.
Yes. With a Mohs hardness of 2, dry ice is softer than limestone and does not abrade any surface. Timber beams, stucco and natural stone remain intact. The method is recommended by heritage conservation authorities.
